Steel Pipes manufacturing process

Steel pipes are long hollow tubes that are used for a variety of purposes. They are produced by two distinct methods, which result in either a welded or seamless pipe. In both methods, raw steel is first cast into a more workable starting form. It is then made into a pipe, by stretching the steel out into a seamless tube, or forcing the edges together & sealing them with a weld.

Welded pipes could be manufactured by one of the process, know as Electric Resistance Welding (ERW), where in a high frequency current is being used to fuse the steel together, resulting in welding at the seam of the pipe.

Worldwide, ERW pipes are manufactured & distributed, looking at the various applications, various people are into manufacturing of steel pipes & tubes, following various Indian & International standards.


Maintaining the quality of the ERW pipes is of utmost importance too. The product must pass through stringent quality tests, before they are finally supplied. Raw Material shall be tested for Chemical Composition, Tensile Strength, Elongation and Thickness & Tolerance. Pipes shall be hydraulically tested to ensure no leakage in the pipe. Galvanized pipes must be tested for uniformity of the zinc coating.

As the quality is the lifeline of any industry, so at Steel pipes manufacturing companies, Quality is not only checked, but is monitored & produced, with the help of proactive & professional approach.

Preventing Frozen Pipes and Burst Lines

Ice formation can occur any place within a length of pipe. Experts say that what causes potential bursting problems is that after the ice blockage, the pipe continues to freeze and expand and cause the downstream water pressure between the ice blockage and the closed faucet to increase.

When and where are your Pipes at Risk?

How vulnerable your pipes are to freezing depends on where they are located in your home.

How can you Prevent Frozen Pipes?

What can you do to prevent freezing? Plumbers offer several suggestions, with the caveat that pipes may still freeze even if you take precautions.

Install insulation and electric heat tape on the pipes prior to winter. Even if the pipes freeze in extreme temperatures, the heat will gradually thaw the pipe.
Seal gaps around the home around dryer vents, windows, cable entry points, etc.
When the temperatures are expected to dip, leave a small trickle of hot and cold water running to relieve pressure. If the dripping stops, still keep the faucets open.
Keep your house warm.
What to do if your Pipes Freeze

If pipes do freeze, it is important to thaw them out and prevent bursting. Make sure that your faucets are open and try these remedies:

Shut off the water supply to the whole house or at least in the section of the home near the frozen pipe.
Wrap the pipe in burlap or towels and pour hot water over the fabric several times until the pipe thaws.
Direct a heat lamp, hairdryer, or space heater toward the frozen area and move. Make sure to plug the appliance into a Ground Fault Circuit Interrupter (GFCI) outlet and aim it toward the pipe from at least a foot away.
When to Call a Licensed Plumber

What are Glass Pipes

Glass Pipes is allowing the user to inhale copied from the burning of some stuff. Tobacco pipe is the most common which designed for use with tobacco. The pipes are counting with a variety of material , commonly used  are: Briar,  Heather,  corn, clay, meerschaum,   glass, porcelain,  cherry, acrylic, ebonite, etc.

Glass Pipes, often called bowls, can be made of blown glass, wood, ceramic, stone, or metal because of ignoring inhalation of unwanted vapors, certain reactive metals like aluminum.  When speaking about a specific pipe, the term "bowl," "cone piece" often refers to the indentation where cannabis is to be combusted.

Blown Glass Pipes are usually complex and colorfully designed, and contain material that becomes brighter with repeated use. These types of pipe generally have a hole which is enclosed with a finger during inhalation, and then uncovered to clear the pipe of smoke and cool the burning cannabis.

Most or people, are getting indulge to tobacco pipes not just only for their taste or smoking purpose but they also for the countless of different kinds of pipes for enjoy its different activities. These pipes can be made up of glass which can be in varied designs and colors.

Firetube Boilers and Watertube Boilers

Firetube Boilers: Firetube boilers are also know as shell boilers. These boilers are the most commonly used boilers in the market. In the firetube or shell boilers the water is surrounded by the water. The water which surrounds the shell or firetube is heated by sending the hot gases or fire which is produced by the burner through the shell or firetube. The hot gases or fires are allowed four times through the tubes in the boiler before letting the out of the boilers. These tubes are generally set at the banks of the boilers. The firetube boiler systems can release up to 25,000lbs or 750hp of steam per hour. About 80% of the boilers that are in use today belong to this particular category.

Watertube Boilers: In the Watertube Boilers the tubes are arranged vertically in the shell. Then the water is filled in the shell which is heated by sending the hot fuel or hot gases through the tubes. Generally Watertube boilers are built in rectangular shape with two or three drums. The drums are arranged at the top and bottom, where top drum is used to separate water and steam and the bottom drum is used to collect he sludge. Watertube boilers are usually utilized when more than 750hp of steam per hour is required.

Working principle of a Boiler

Every household in the United Kingdom has a central heating boiler in their houses. But anyone of you has ever thought how does a central heating boiler work. Today I am going to explain how exactly the central heating system (boiler) works.

The water stored in the vessel when heated to a desired temperature level by burning natural gases, coal and wood pellets can be defined as a boiler. The steam produced by the boiler when heated is piped to a spot which can be is utilized for different purposes such has running the production units, sanitizing some area, sterilizing equipments, to warm up the surroundings, to heat up the water, and many more.

After the burners are heated up using the required fuels, then the gases or the fire from the burners are directly released on the boiler to heat up the water. The water can be boiled in the boiler depending on the two types of boilers used in the market.

There are generally two types of boilers which use their own principles to produce heat.

Industries require DTH Drill Pipe for their Complex Drilling Works

To meet the drilling requirements of various industrial sectors, the need for drill pipes has become inevitable. Most of the industries like construction, mining, oil &gas require DTH drill pipes to accomplish their drilling activities. The specially designed drill pipes enable a core to be easily extracted out of earth's surface or rock. The entire length of the pipe seamlessly enters beneath the earth's surface and digs out the mass to obtain even drilled holes. The profitability of these industries depends upon the drilling efficiency of the drill pipes. Hence, it is very important for the industries to choose best designed drilling tools from reputable manufacturers.

Get accustomed with the DTH drill pipe

DTH drill pipe is industrial tubular drilling equipment used to bore the ground surface. The most frequent application of this kind of tubular drilling tool is in the oil and gas industry. The DTH drilling pipe is provided with an external steel tube fabrication for greater longevity and higher working efficiency.

Why professionals use DTH drill pipes for their extensive drilling tasks?

DTH drill pipes are manufactured and designed in such a manner that it can effectively reduce the hardships of the drilling worker. These drilling tools do come with effective features and specifications to fulfill the different requirements of the professionals. Plumbers may require drilling pipes, to dig large holes in studs and joists. This can ease out their job of installing drains and waste pipes, beneath the surface of the Earth. Also because the plumber is drilling large holes, up to 4 inches, the right angle drill pipe will accomplish his drilling needs efficiently.

The Power of PEX Tubing

What is so special about PEX tubing? Isn’t it just a plastic plumbing pipe? Wait a minute, is it Polybutylene tubing that I heard about so many class-action lawsuits about? Slow down. It is not the Polybutylene that took a bad rap a few years ago. This is a hybrid, and it is a cross-linked Polybutylene tubing. Yes, it is plastic, but it offers numerous advantages to metallic water-distribution piping systems.

Polybutylene is grey in color. PEX comes in white, blue, and red colors. This is advantageous in that cold water can be piped with blue tubing and hot water can be piped with red tubing. PEX can expand up to one-third of its own diameter before bursting when it is frozen. Compare this to copper tubing and you will see instant advantages.

Copper tubing, which is common in most homes that people now live in, is subject to chemical reactions that can create leaks. Acid is one such chemical reaction. Too much acid in copper tubing will create pinholes. The holes may be tiny, but the water damage can be disastrous. This is not a problem when PEX tubing is used.

PEX installations require less time for a plumber’s labor. Most of us know how much plumbers charge for their time, so this is a no-brainer. No flame is required to install PEX tubing. This is another difference between PEX and copper. Go with the PEX!

Check the price of copper. Compare it with PEX. Again, you have a no-brainer. PEX fittings are more expensive than copper fittings, but fewer are needed and the additional cost of the fittings doesn’t amount to much when you compare the cost of the tubing itself.
I used Polybutylene (PB) back in the 1970’s and for many years following with no problems. However, the installation procedure required some precise work. Personally, I feel that PB got a bad rap, but PEX is installed with essentially the same procedures and it is great.

As an old-school master plumber with over 30 years of experience, I am probably supposed to support copper, but I don’t. For general residential applications, PEX is the player. It is cheaper, faster to install, and in many ways it offers superior service.

PEX joints are made in two ways. There are crimping tools and crimp rings. This is the system that I use. Another system, and it is equally good, uses an expansion tool on the tubing that opens the tubing and then allows it to grip onto fittings. These are the two professional means of installation.

Homeowners can use compression fittings to make easy connections with PEX. All you need to make a leak-proof joint is two adjustable wrenches and a compression fitting. The tubing is cut professionally with a sharp cutting tool, but a homeowner can cut the tubing with a knife or a hacksaw. There are also new fittings available that allow homeowners to basically jab the pipe into the fitting for a solid fit.

If you want to repipe your house, repair a section of piping, or add to your plumbing system, I strongly recommend a PEX tubing connection. The compression fittings that I spoke of earlier allow you to transition from copper to PEX. You can do it, and you don’t need super skills or pro tools. Go for it!

Uses And Benefits of Carbon Steel

All types of steel contain carbon but carbon steel has more carbon content. It also includes manganese and iron. It is considered to be one of the most widely used steel metals. It has many uses and advantages compared to other types of metals. It is also known as wrought steel and it can be formed into any shape. It is quite malleable and therefore it can be made into desired shapes. It is poured into blocks that are rolled to form desired shapes.

Carbon steel is categorized into three types which include low or mild steel, medium steel and high carbon content. The low alloy is easy to form and shape as it includes low level of carbon. Medium carbon steel is mainly used to make shafts, couplings and axles.

Low Steel: It contains lower level of carbon constituent as compared to other alloys. It is comparatively cheaper than the other types of metals and it is widely used for various construction purposes. It has low strength and durability.

Medium Steel: Another alloy of steel includes the medium carbon steel which is resistant to wear and tear. It is durable and strong. It is used to manufacture large metal structures and automotive components.

High Steel: One of the strongest carbon steel metals includes the high steel variety. It is mainly used to manufacture high strength springs and wires.
Another notable variety of steel includes the ultra high steel metal which is very tensile and strong. It is mainly used to manufacture knives and axles.

All these types of steel metals are used to manufacture various types of industrial tools and machines. It is also used to manufacture drilling bits as it is strong and tensile. It is even used to manufacture cutting tools and nails. High steel is mainly used to manufacture drill bits, knives and cutting tools as it is strong and versatile.

In addition to this constituent, many other elements such as manganese, chromium and tungsten are used as hardening agents. The properties of steel can be determined by the proportion of these elements.

Stainless steel which contains high level of this alloy is known to be rust proof and strong. Although this type of steel is inclusive of various benefits, it includes certain disadvantages. It is known to be brittle and therefore it can seldom be used for constructing building and bridges. Steel with low level of the main alloy can be used for various purposes as it is less brittle and stronger.

Nevertheless, it is used for manufacturing steel pipes as it tends to remain intact. It is also known to be durable and resistant. As it is anti-corrosive, it can be used for under water purposes. It has the ability to withstand high pressure and therefore it is used for various industrial purposes.

Most of carbon steel these varieties of steel alloys can be bought at affordable price rates. There are many industries which manufacture steel pipes and maintenance tools in the country.

Types and Properties of OCTG Pipe

OCTG stands for Oil Country Tubular Goods and covers several types of pipes and tubes that meet the standards of the American Petroleum Institute (API). OCTG covers three types of seamless tubes that have been quenched and tempered. OCTG drill pipe is heavy, seamless tubing that is used in drill strings for rotating the drill bit and circulating the drilling fluid. Normally 30 feet long, OCTG drill pipe is coupled with tool joints. OCTG casing pipe is pipe used to line the drill hole, and OCTG tubing transports the oil or gas that's produced in the wellbore. OCTG tubing is also around 30 feet long and comes with thread connections on either end.
Low allow steel grades used in OCTG pipe are traditionally carbon-manganese steels, or alloys with up to 0.4% molybdenum. However, in recent years, contaminants in drilling reservoirs and deep drilling applications have increased the demand for OCTG products that are more resistant to sulfide stress cracking and hydrogen embrittlement. For these applications, highly-tempered martensite has been found to be most resistant to sulfide stress cracking. Highly-tempered martensite with molybdenum concentrations of 0.75% offer the best combination of sulfide stress cracking resistance and high yield strength. When even higher yield strengths are needed, the addition of niobium offers yield strengths of up to 140 kilo-pounds per square inch.
Stainless steel API grades are standardized with 9% chromium plus 1% molybdenum or 13% chromium with no molybdenum. High temperature environments with carbon dioxide and hydrogen sulfide demand improved resistance to corrosion and sulfide stress cracking. Niobium and molybdenum improve corrosion resistance, with molybdenum improving pitting corrosion resistance, thus eliminating areas where sulfide stress cracking can get a foothold.
OCTG products meeting API 5CT or 5D specifications fall into 16 grades based on minimum yield strength, maximum yield strength, maximum tensile strength, and estimated Rockwell C hardness. For example, grade H-40 has minimum tensile strength of 60,000 psi, minimum yield strength of 40,000 psi, maximum yield strength of 80,000 psi, and estimated hardness of 70 to 87 on the "B" hardness scale, or HRB. At the other end of the scale, Grade S has minimum tensile strength of 145,000 psi, minimum yield strength of 135,000 psi, maximum yield strength of 165,000 psi, and estimated hardness of 32 to 39 (HRB).
Inspection classifications for new tubing and plain end drill pipe are designated by different colors of banding. White Band products are suitable for all inspections performed, while Yellow Band products are considered repairable rejects. With Yellow Band products, the bands are located on either side of the defect. Blue Band products have imperfections whose depth is undetermined. Red Band items must have body wall defects cut out of the tube for it to be usable. Damaged ends are marked with red bands, and drift restrictions are also designated by red bands located on either side of the restriction.

Your OCTG supplier should be conversant in pipe the various grades and classifications of OCTG piping and tubing so you can be confident you get the exact products your project requires.

Acidic Water Filtration Systems Prevent Copper Pipe Corrosion on Acid Well Water

In thousands of homes on Corrosion Pipe well water, acidic water causes thinning of copper pipes, pinhole leaks, and numerous copper pipe leaks over time. Acidic water filtration systems can easily correct and neutralize a low pH in well water.

The pH scale is a scale from 1 to 14. A neutral pH is 7. A ph of less than 7 is considered acidic. A pH greater than 7 is considered alkaline and is less corrosive to copper pipes than waters with a pH of less than 7.

Signs of acid water are corrosion of fixtures, blue staining (from copper pipes) or rust staining (from iron pipes). Acidic water can also cause pinhole leaks and pipe failure over time. By raising the pH to the range of 7.0 to 7.5 the water can be made alkaline which will then reduce or eliminate pipe corrosion.

Common causes for acidic water are acid rainfall due to atmospheric carbon dioxide and other airborne pollutants, runoff from mining spoils, and decomposition of plant materials. Acidic waters can be of good quality and are typically low in buffering calcium minerals, but are high in dissolved carbon-dioxide gas, which can cause the low pH or acidity.
An acidic water filtration system is also known as a calcite neutralizer filter. One of the most convenient methods to raise pH, and add a little hardness and alkalinity is to use a calcite neutralizer filter. These filters will typically raise the pH of the water to 7.0 to 8.0 and add 30 to 100 ppm of hardness depending on the alkalinity and water hardness. The water will taste better and in most applications no water softener will be required after the calcite neutralizer filter.

In neutralizer filters, the acidic water slowly dissolves the calcium and magnesium media on contact as the water flows through the filter, raising the pH of the water and increasing the alkalinity. This eliminates the effects of corrosive water chemistries and can help to prevent corrosion of piping and fixtures.

The size of the system is directly proportional to the flow rate of the water, in gallons or liters per minute. The higher the flow rate, and the more gallons per minute flows through the pipes, the larger the system required. Generally for most homes with 1 bathroom, a 1 cubic foot size system containing 100 lbs of calcite will work well. For homes with 1 to 2 bathrooms, a 1.5 cubic foot filter is recommended. For higher flow demands and in homes with 3 to 4 bathrooms and larger families, a 2.5 cubic foot neutralizer containing 250 lbs of calcite is recommended.
Neutralizer filter tanks contain a small amount of filter gravel in the bottom of the tank and are filled to two-thirds full with a blend of calcium and magnesium carbonates made from naturally occurring minerals. These minerals dissolve into the water, making it less corrosive. More mineral can quickly and easily be added to the filter tank, typically once per year for most residential applications. No special tools are required.

The neutralizer filter should be installed after the pressure tank but before any copper piping in the house. If the pressure tank, check valve and pressure switch are installed with copper piping the copper piping should be replaced with PVC or stainless steel pipes up to the inlet of neutralizer filter. It is OK to have copper pipes installed on the outlet of neutralizer filter since the water is neutralized at this point and the pipe will be protected.

This type of neutralizer also acts as a filter removing sediment and small amounts of rust from the water, and then backwashing it out once every week or so. The most common type of acid neutralizer filter has an automatic backwash control valve. The frequency and length of the backwash cycle can be easily adjusted on the control valve. Most backwashing acid neutralizer filters are set to backwash once a week for eight to ten minutes. This backwashing cleans the calcite filter media and allows the mineral media to Corrosion Pipe more easily dissolve into the water over time.
Various steel pipe external coating projects are currently implemented by our company including single-layer/ double layer FEB, 2PE, 3PE, 3PP and other anti-corrosion coatings with the performed standards such as DIN 30670, DIN 30671, DIN 30678, CAN/CSA-Z245.21-M92, SY-/T4013-2002,SY/T0315-97 etc.

Some of the diverse applications of Stainless steel seamless pipe

Stainless steel seamless pipes have become very common these days and are offered by almost all steel pipes manufacturers. The benefits such as higher corrosion resistance than carbon steel and conventional stainless steel and light –weightiness make the design and construction compact and light. Stainless steel is composed of copper, chromium, nickel, tungsten, manganese, etc. and is therefore rust resistant. Stainless steel seamless pipes can prove to be a cheaper alternative to the nickel alloys, which are very costly. Steel has higher strength which leads to reduced thicknesses of section and therefore has reduced weight. It also exhibits good weld ability in thick sections and the ability to be welded is more in stainless steel. Resistance to stress corrosion cracking: Austenitic steel is prone to such corrosions. The resistance posed by stainless steel to stress corrosion cracking makes this material fit for purposes like Hot water boilers, brewing tanks and desalination, structure of swimming pools, etc.
Steel was invented around 100 years ago. The importance of steel has risen by leaps and bounds due to various reasons and attributes of steel. Steel does not get rusted easily and is light-weight as compared to Iron. It is durable, ductile, malleable, corrosion resistant and fire-resistant among scores of other benefits. All these features of Steel have made it the king of raw materials used in almost every industry. Steel is mostly used as structural steel which is the most preferred framework material for residential as well as non-residential construction. The steel beams and columns are the skeleton of the building and support the entire construction just like the bones in a body do. Angle bars, I-Beams, H beams, IPE etc. are some of the other structural elements requited in the construction. It is therefore clear that steel is indispensable in industries. The specially processed steel like galvanised steel has made steel more versatile and fit for various purposes. Some of the commonly used steel products are steel sections, steel pipe, steel tube, steel coil, steel sheet and steel plate. The process of galvanisation increases the strength and durability of steel. Steel has several grades and steel prices vary accordingly. Other types of steel are
Stainless steel pipe and tubes are some of the most common application of steel which are used in most industries as well as household. Steel pipes are used as curtain and drapery rods, plumbing pipes, parts of the mechanical equipments and various other uses.

General Knowledge of Seamless Steel Pipe

Seamless steel pipe is a long steel with hollow sections and has no joints surrounding the steel bar. It is mainly used as a pipeline to transfer the fluid, such as oil,natural gas,water and some solid materials,etc. As compared to the flexural torsional strength in the same light, it is an economic cross-section steel. The seamless steel pipes are widely used in the manufactures  and mechniacal parts,such as the oil pipe, automotive transmission shaft,bicycles aircraft,as well as buliding construction. With steel pipe manufacturing, annular parts can improve the material utilization, simplify the manufacturing process, save material and machining time. For example, the roller bearing rings and the jack sets and so on have been widely made of steel pipes. Cylindrical rube can delivery more fluid since the circle has the largest areas under the same circumference. In addition, the ring cross-section bears internal or external pressure, the force more evenly, so that vast majority of tubular steel pipes are cylindrical rubes . However, the tube also has some limitations, such as in-plane bending conditions, the pipe on the better side, rectangular tube bending strength, and a number of sets of frames, steel-wood furniture on the commonly used square, rectangular tube.
Pressure pipelines are generally composed of pieces of standard parts, so the pressure pipe design component is the selection of its standard parts. the pressure level of pipelines is determined to the pressure level of its standard parts.
The parameters of channels characteristics which are determined by the nominal pressure level and wall thickness are called the pressure grade of the pipes.
the determine of the pressure  grades is not only the basis for pipeline design, but also the core of design. It is the basis of the arrangement of pressure pipe, and pressure pipe stress precondition for checking the design. and it is also an important factor which will affect investment and reliability.
carbon seamless steel pipes are widely used in gas, water and oil, transpotation;constructions;Bridge,highway,windows of model steel door; building materials;fences;heating facilities Fluid Pipe;conduit pipe,scaffolding pipe.etc.

Lancashire Boiler - a fire tube boiler

Now a days steam boilers are very popular which are used to convert water into steam at constant pressure. There are number of fire tube boilers. Some of them are Cochran Boiler, Lancashire Boiler, Locomotive Boiler etc. Here is some information available about Lancashire Boiler.

Lancashire Boiler is a fire tube boiler having internally fired two horizontal fire tubes. Each of the flue tube has a fire grate where flue is fed through fire holes. The water shell is having water and is placed in the brickwork setting the hollow brickwork works as the flue path, which ensures complete combustion of fuel.

Flue gases traverse the flue tubes from front to the back, where it dips down and pass under the boiler shell back to the front. In the front these gases are divided into paths and pass by the sides of the shell and traverse from front to the back and finally escape through the chimney. This path of flue gases enables the utilization of heat available in the flue gases to the maximum extent.
These types of boilers have a normal working pressures up to 15 kg/cm2, and are used for process steam requirement like sugar or textile industries.

All in all Lancashire Boiler is commonly used fire tube boilers. There are also other types of boilers that are Cochran Boiler and Locomotive Boiler which have diffrent functionality and work. Lancashire Boiler is mostly used for process steam requirement. In the textile industries Lancashire Boiler is very much useful.

Uses And Benefits of Carbon Steel

All types of steel contain carbon but carbon steel has more carbon content. It also includes manganese and iron. It is considered to be one of the most widely used steel metals. It has many uses and advantages compared to other types of metals. It is also known as wrought steel and it can be formed into any shape. It is quite malleable and therefore it can be made into desired shapes. It is poured into blocks that are rolled to form desired shapes.

Carbon steel is categorized into three types which include low or mild steel, medium steel and high carbon content. The low alloy is easy to form and shape as it includes low level of carbon. Medium carbon steel is mainly used to make shafts, couplings and axles.
Another notable variety of steel includes the ultra high steel metal which is very tensile and strong. It is mainly used to manufacture knives and axles.

All these types of steel metals are used to manufacture various types of industrial tools and machines. It is also used to manufacture drilling bits as it is strong and tensile. It is even used to manufacture cutting tools and nails. High steel is mainly used to manufacture drill bits, knives and cutting tools as it is strong and versatile.

In addition to this constituent, many other elements such as manganese, chromium and tungsten are used as hardening agents. The properties of steel can be determined by the proportion of these elements.

Stainless steel which contains high level of this alloy is known to be rust proof and strong. Although this type of steel is inclusive of various benefits, it includes certain disadvantages. It is known to be brittle and therefore it can seldom be used for constructing building and bridges. Steel with low level of the main alloy can be used for various purposes as it is less brittle and stronger.

Nevertheless, it is used for manufacturing steel pipes as it tends to remain intact. It is also known to be durable and resistant. As it is anti-corrosive, it can be used for under water purposes. It has the ability to withstand high pressure and therefore it is used for various industrial purposes.

Some of the diverse applications of Stainless steel seamless pipe

Stainless steel seamless pipes have become very common these days and are offered by almost all steel pipes manufacturers. The benefits such as higher corrosion resistance than carbon steel and conventional stainless steel and light –weightiness make the design and construction compact and light. Stainless steel is composed of copper, chromium, nickel, tungsten, manganese, etc. and is therefore rust resistant. Stainless steel seamless pipes can prove to be a cheaper alternative to the nickel alloys, which are very costly. Steel has higher strength which leads to reduced thicknesses of section and therefore has reduced weight. It also exhibits good weld ability in thick sections and the ability to be welded is more in stainless steel. Resistance to stress corrosion cracking: Austenitic steel is prone to such corrosions. The resistance posed by stainless steel to stress corrosion cracking makes this material fit for purposes like Hot water boilers, brewing tanks and desalination, structure of swimming pools, etc.
Steel was invented around 100 years ago. The importance of steel has risen by leaps and bounds due to various reasons and attributes of steel. Steel does not get rusted easily and is light-weight as compared to Iron. It is durable, ductile, malleable, corrosion resistant and fire-resistant among scores of other benefits. All these features of Steel have made it the king of raw materials used in almost every industry. Steel is mostly used as structural steel which is the most preferred framework material for residential as well as non-residential construction. The steel beams and columns are the skeleton of the building and support the entire construction just like the bones in a body do. Angle bars, I-Beams, H beams, IPE etc. are some of the other structural elements requited in the construction. It is therefore clear that steel is indispensable in industries. The specially processed steel like galvanised steel has made steel more versatile and fit for various purposes. Some of the commonly used steel products are steel sections, steel pipe, steel tube, steel coil, steel sheet and steel plate. The process of galvanisation increases the strength and durability of steel. Steel has several grades and steel prices vary accordingly. Other types of steel are
carbon seamless steel pipes are widely used in gas, water and oil, transpotation;constructions;Bridge,highway,windows of model steel door; building materials;fences;heating facilities Fluid Pipe;conduit pipe,scaffolding pipe.etc.

Industries require DTH Drill Pipe for their Complex Drilling Works

To meet the drilling requirements of various industrial sectors, the need for drill pipes has become inevitable. Most of the industries like construction, mining, oil &gas require DTH drill pipes to accomplish their drilling activities. The specially designed drill pipes enable a core to be easily extracted out of earth's surface or rock. The entire length of the pipe seamlessly enters beneath the earth's surface and digs out the mass to obtain even drilled holes. The profitability of these industries depends upon the drilling efficiency of the drill pipes. Hence, it is very important for the industries to choose best designed drilling tools from reputable manufacturers.

The oil and gas industries utilize such drilling pipes, to effortlessly reach down to extreme surface of the ground surface. The oilfield drill pipe is drilled into the earth vertically by using the drilling rig and the oil is obtained effectively. Construction industries also make use of DTH drill pipe to bore tunnels under waterways or major roadways of a highly populated town. The resultant bore is thereby used for a variety of utility pipelines such as, fiber optic, water, electricity, oil and gas.

DTH drill pipes are manufactured and designed in such a manner that it can effectively reduce the hardships of the drilling worker. These drilling tools do come with effective features and specifications to fulfill the different requirements of the professionals. Plumbers may require drilling pipes, to dig large holes in studs and joists. This can ease out their job of installing drains and waste pipes, beneath the surface of the Earth. Also because the plumber is drilling large holes, up to 4 inches, the right angle drill pipe will accomplish his drilling needs efficiently.

SSAW Carbon Steel Pipe

Steel Pipes manufacturing process

Steel pipes are long hollow tubes that are used for a variety of purposes. They are produced by two distinct methods, which result in either a welded or seamless pipe. In both methods, raw steel is first cast into a more workable starting form. It is then made into a pipe, by stretching the steel out into a seamless tube, or forcing the edges together & sealing them with a weld.

Welded pipes could be manufactured by one of the process, know as Electric Resistance Welding (ERW), where in a high frequency current is being used to fuse the steel together, resulting in welding at the seam of the pipe.

Worldwide, ERW pipes are manufactured & distributed, looking at the various applications, various people are into manufacturing of steel pipes & tubes, following various Indian & International standards.
