SSAW (spiral submerged arc welding) steel pipe, also called HSAW pipe, produced by spirally welding hot rolled coils, with welding seam in spiral (helix) type, can be manufactured in large diameter(OD219mm to 2540mm) and length. With characters of high strength, superior pressure resistance(reducing stress on the weld 75%-90% compared to straight-seam pipe), durability and low cost, commonly used for oil, gas and water transmission, structural piling for civil Engineering works or architecture, concrete casing, etc.
