SSAW pipe is the raw material of strip coil, often temperature extrusion molding, automatic double-wire doubl ,Large diameter thick - walled spiral steel pipe

SSAW pipe is the raw material of strip coil, often temperature extrusion molding, automatic double-wire double submerged arc welding process made of spiral seam pipe. Spiral steel pipe will strip into the pipe unit, the multi-roll rolling, strip rolled up, forming a circular gap opening gap, adjust the squeeze roll reduction, the weld gap control in the 1 ~ 3mm, and make both ends of the weld flush. Q235B spiral steel pipe for drainage
