For High pressure and high temperature

ERW pipe is manufactured by cold forming a flat steel strip into a rounded tube and passing it through a series of forming rollers to obtain a longitudinal seam. The two edges are then simultaneously heated with a high frequency current and squeezed together to produce a bond. The longitudinal ERW seam does not require filler metal while impurities in the heat affected zone are extruded during the welding process.

A few advantages to note with ERW pipe:

• There are no fusion metals used during the manufacturing process. This means that the pipe is extremely strong and durable.
• The weld seam cannot be seen or felt. This is a major difference when looking at the double submerged arc welding process, which creates an obvious welded bead that might need to be eliminated.
• With the advances in high-frequency electric currents for welding, the process is far easier and safer.
