Spiral welded pipe is made by steel plates or coils, formed by spiral Submerged Arc Welding type. The welding type SAW is the same with LSAW pipe, it’s just the welded seam shape is spiral or helical.

Spiral welded pipe could produce the large diameters max. up to 3048mm, with wall thickness 5mm to 30mm. The advantage is low production cost and material savings. And the length could reach longer up to 32meters in accordance to the steel mill facility and site. Spiral steel pipes are used in water, petroleum & gas, chemicals, power, irrigation and city construction etc.
