SSAW

Sprial welded steel pipe(SSAW) is mainly used in oil and gas transmission pipeline,and its  specification is expressed as outside diameter * wall thickness .according to the external  structure, it is classfied single welding and double welding. Technically,the welded steel  pipe should ensure that hydrostatic test, weld tensile strength and the cold bending property  can comply with the regulations.


Size:
Outer Diamter: 219.1mm - 4064mm (8" - 160")
Wall Thickness: 3.2 mm - 40mm
Length: 6mtr-18mtr
