Website: ERW steel pipe
The High-Frequency Longitudinal Seam Welded Steel pipe is also called ERW steel pipe, it’s manufactured by cold-forming a sheet of steel into a cylindrical shape. Current is then passed between the two edges of the steel to heat the steel to a point at which the edges are forced together to form a bond without the use of welding filler material.
MAIN CHARACTERISTICS OF ERW STEEL PIPES:
High-security welding seam: as a result of special welding method of melting of the parent metal together without filler metal, the welding property is better and the welding seam is much smaller than spiral welded pipes.
Cost effective and short production period
A wide range of thickness/diameter ratio, covering hundreds of specification
In –line inspection and testing
