  10. How Pipe Is Manufactured - Midstate Steel

    How Pipe Is Manufactured. ERW pipe is cold formed into a cylindrical shape rather than hot formed. An electric current rather than a flame 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.
