Spiral Welded Steel Pipe SSAW Steel Pipe
Most submerged arc welded pipes are large diameter ones.
SSAW pipe is Spiral Submerged Arc Welding pipe.
It is to roll structural steel strip into tube blank according to a certain angle of helix (called forming angle), and then weld the pipe seam to make it. It can produce large-diameter steel pipe with narrow strip steel.
Its strength is generally higher than that of straight welded pipe, and it can produce welding pipe with larger pipe diameter with narrow steel strip.
Application: SSAW pipe is mainly used for pipeline transportation. Our products are used for potable water lines, irrigation systems, casings, conveyance and penstock piping for hydropower plants, piling support for bridges, ports, and wharf infrastructure, structural columns, and oil and gas distribution.
