Some buyers haven't a very clear concept about what is ERW pipe and what is ERW tube manufacturing process, they also don’t know its application. Today, Prime steel pipe will give you a detailed introduction about that.


What is ERW pipe?


ERW pipe (also called ERW steel pipe) is the abbreviation Electric Resistance Welded Pipes. Electric resistance welding refers to a group of welding process (including spot and seam welding) that produce coalescence of faying surfaces where heat to form the weld is generated by the electrical resistance of material combined with the time and the force used to hold the materials together during welding. ERW steel pipes and tube are available in various qualities, wall thicknesses, and diameters of the finished pipes.


What is ERW tube manufacturing process?


ERW steel pipe is manufactured by rolling metal and then welding it longitudinally across its length. ERW steel pipes are welded longitudinally, manufactured from Strip / Coil and can be manufactured up to 24”OD. ERW pipe cold formed from a ribbon of steel pulled through a series of rollers and formed into a tube which is fused through a electric charge.


Typical ERW tube manufacturing process of Prime Steel Pipe generally involves the following stages in a step by step procedure.




The application of ERW steel pipe


ERW steel pipes are used in various engineering purposes, fencing, scaffolding, line pipes etc. It is available in lengths from single random to 120 feet depending on mill capability. What's more, ERW steel pipes are usually used for Agricultural purposes, Drinking Water for housings, in collieries for extraction of Water, Thermal Powers, Transports, Hand pumps for deep boring wells, as a strong protection for cables by Telecom Department, Structural Purposes etc. ERW steel pipe is available with square ends or beveled for welding, threaded and coupled and victaulic grooved. Surface finish of it is available in black or bare, or with protective coatings.


Prime Steel Pipe have a very large production capacity of ERW steel pipes, so that we can manufacture ERW pipes and tubes of different size and shape based on the customers requirements.
