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.

In India many organization, are engaged into manufacturing & exporting of Quality ERW Pipes. They manufactures different types of ERW Pipes namely Black Pipes, Hot Dip Galvanized Pipes, Conduit Pipes, Casing Pipes, Scaffolding Pipes & General Engineering Purpose Pipes.

These companies have huge production capacities, & holds certification of various Indian as well as 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.

Steel Pipes finds various applications in Commercial, Industrial, Residential & Agricultural areas. These pipes are used in Staircase Hand railings, Door Frames, Oil & Gas Industry, Structural & Scaffolding purposes, Green Houses, Shed for ware houses, Sanitary use of households, Sewage, Construction activities, Hand Pumps, Tube Wells, Boring, Water Distribution System & several other applications.

Diversified form of steel is yet to come, which will change the face of all economies, with easy applicability adaptability, affordability, viability & stability.
