ERW pipe is abbreviation of ELECTRIC RESISTANCE WELD PIPE.

ERW pipe is produced from individual sheets or steel coils. Firstly the steel sheet is cold formed into a cylindrical shape by extreme pressure of the rolls, steel plate is extruded on both the inside and outside of the cylindrical shape at the point of the weld, and an electric current is used to heat the edges of the strip for the fusion weld revolving copper discs serve as electrodes and raise the temperature to about 2600°F for effective welding.


ERW pipe is primarily used as API Line pipe for the transmission of gas and oil. It is also used for the transmission of water, under AWWA specifications, as piling and slurry pipe and in mechanical applications.

Electric Resistance Weld pipe is normally produced in sizes from 2 3/8 inch OD through 26 inch OD.
