API 5L Spiral welded pipe for line pipe - steel pipe, ERW

API 5L spiral welded pipe could be used in petroleum oil and gas, and other fluid transmission. In order to protect the pipe from rust, anti-corrosion coating may be applied in accordance to the contractors option. External 3PE, 2PE, FBE, coal tar epoxy, internal FBE, coal tar epoxy, cement mortar lining etc. The coating layer will protect the line pipe and kept the usage time longer than 20 to 30 years in accordance with the media surrounding the pipes. Advantages and disadvantages of spiral steel pipe - abter Mar 23, 2021 · Spiral steel pipe is a spiral steel pipe made of strip steel or coiled plate in a spiral shape, using double-sided submerged arc active welding to weld the inner and outer seams. It can be widely used in water, electricity, and chemical industries for the following reasons In professional production:just by changing the forming viewpoint, steel pipes of various calibers can be produced

EN10219 spiral welded pipe for structure usage - steel

EN10219 spiral welded pipe is used for welded structure hollow sections. Spiral welded pipe with spiral welded seam by double submerged arc welding to form the steel plates/coils into one pipe. Compare to EN10219 ERW/LSAW/seamless pipes the advantage is the low products cost and high Material yield, with the large diameter and longer extent. Performance comparison of spiral steel pipe and straight The spiral angle of the spiral steel pipe weld is generally degrees, so the resultant stress at the spiral weld is the principal stress of the longitudinal welded pipe. Under the same working pressure, the wall thickness of spiral welded pipes with the same diameter is Quality inspection method of spiral steel pipe - Threeway For steel spiral welds conveyed by flammable ordinary fluids, 100% X-ray or ultrasonic testing should be carried out. The spiral welds of steel pipes that transport water, sewage, air, heating steam, and other general fluids should be inspected by X-ray or ultrasonic.
