Electric Resistance Welding (ERW) steel pipe is manufactured by rolling metal and then welding it longitudinally across its length. Seamless steel pipe is manufactured by extruding the metal to the desired length; therefore ERW steel pipe have a welded joint in its cross-section, while seamless steel pipe does not have any joint in its cross-section through-out its length.

In seamless steel pipe, there are no welding or joints and is manufactured from solid round billets. The seamless steel pipe is finished to dimensional and wall thickness specifications in sizes from 1/8 inch to 26 inch OD. Applicable in for high-pressure applications such as Hydrocarbon Industries & Refineries, Oil & Gas Exploration & Drilling, Oil & Gas Transportation and Air and Hydraulic cylinders, Bearings, Boilers, Automobiles etc.

ERW steel pipes are welded longitudinally, manufactured from Strip / Coil and can be manufactured upto 24” OD. ERW steel 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. It is mainly used for low/ medium pressure applications such as transportation of water / oil. 

Common sizes for ERW Steel Pipe range from 2 3/8 inch OD to 24 inch OD in a variety of lengths to over 100 feet. Surface finishes are available in bare and coated formats.
