7Uses: Welded steel pipes for use in pipeline transportation system in the petroleum and natural gas (oil & gas) industries, water pipeline, ructural & construction.ERW pipes means Electric Resistance Welded Pipes. ERW steel pipes and tubes are used. ERW steel pipes and tubes are used in various engineering purposes, fencing, scaffolding, line pipes etc. ERW steel pipes and tube are available in various qualities, wall thicknesses, and diameters of the finished pipes. Our product finds its usage 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. While manufacturing ERW steel pipes, only high-quality, continuous-cast, fully killed, control-rolled, fine-grain, low-carbon steel is used. High performance ERW steel pipes and tubing possess high strength corrosion resistance, high deformability, high strength and high toughness. We are among the leading manufacturers and suppliers of erw pipes and tubes in India. We are also one of the largest exporters of erw pipes and tubes in India. ERW pipes and tubes stands for Electric Resistance Welded pipes and tubes. Based on the customers requirements we can manufacture erw pipes and tubes of different size and shape. We have a very large production capacity of erw pipes and tubes. ERW pipes and tubes are used in various engineering purposes, fencing, scaffolding, line pipes etc. ERW pipe is available in lengths from single random to 120 feet depending on mill capability. ERW pipe is available with square ends or beveled for welding, threaded and coupled and victaulic grooved. Surface finish are available in black or bare, or with protective coatings.

ERW pipes are manufactured starting from steel coils, that are at first uncoiled, cut, processed, welded, and tested as shown in the picture below.
The most common welding technique used for oil and gas pipes is the so-called “high-frequency induction technology” (ERW-HFI), consisting in the application of an induction current on the outer surface of the pipe able to generate a robust seam weld and join the two sides of the steel coil very tightly.

ERW pipes are available in sizes between 1/2 and 20 inches, in carbon steel (ASTM A53 is the most common specification) and stainless steel (ASTM A312). In terms of dimensions, the ASME B36.10 and ASME B36.19 are the key reference specifications (API 5L for welded ERW line pipes).
The ASME and API dimensional charts show typical combinations of pipe nominal size and wall thickness (designated as “schedule”), and show ERW pipe weight in kg (or pounds).
In the last few years, ERW pipes are have become an efficient alternative to seamless pipes, both in terms of price and performance, due to the modern welding technologies adopted by ERW pipe manufacturers (example HFI and HFW, high-frequency welding). These advancements in welding technologies have reduced, over time, the technical superiority of seamless pipes vs ERW pipes, making them interchangeable at least in some applications (low/medium pressure and temperature). Of course, seamless pipes will always benefit from the intrinsic superior mechanical strength of steel billets vs. coils and plates.
