SSAW steel pipe (Spiral Submerged Arc-Welding Pipe), also called HSAW pipe (Helical SAW), welding line shape like a helix. It uses the welding technology of spiral submerged arc-welding. There is a wide application for SSAW steel pipes, such as oil and gas pipeline systems, construction structure, water transport and sewage treatment, thermal industry, buildings, etc.
