Black ERW & Seamless Pipe - Steel Supply, L.P

Pipe is generally divided into seamless pipe and welded pipe. Welded pipe, sometimes called ERW (Electric Resistance Welded), is made by forming a flat piece of steel into a round shape and welding the edges together. Seamless pipe is made by drawing a solid piece of steel over a mandrel to create a solid tube without a weld seam. Difference between Seamless and erw Stainless steel pipe Nov 24, 2014 · It is mainly used for low/ medium pressure applications such as transportation of water / oil. Pearlites steel is one of the leading ERW Stainless Steel Pipes Manufacturer and exporter from India. Contact us for product details. 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.

Differences between ERW Steel Pipe and HFW Steel Pipe

ERW steel pipe is manufactured through low or high frequency resistances Electric Resistance. Welding seam is in longitudinal. During the ERW pipe welding processes, the electric current will make the heat when flow through the contact surface of the welding area. It will heat the 2 edges of the steel to a point that the edges can form a bond.
