What is The Differences Between LSAW Pipe and SSAW Pipe
The SSAW pipe diameter range is from 20 inch to 100 inch, 406 mm to 2540 mm.The advantage part is we can get the different diameter of SSAW pipes with the same size of the steel strip, there is a wide application for the raw material steel strip, and welding seam should avoid the primary stress, good performances to bear the stress.
What is a SSAW pipe?. Spiral submerged arc welded steel pipe is a kind of metal pipe with spiral seam welded by submerged arc welding technology.. SSAW pipe is made of hot rolled coiled steel by automatic submerged arc weld under normal atmospheric temperature. All the pipes are produced according to API Spec 5L, GB/T9711.1, GB/T9711.2, ASTM A252-89 standard.
Borun is an experienced manufacturer & exporter of OCTG Pipes, Seamless Pipes, Hollow Section, ERW,LSAW pipe and Galvanized Pipes in China making the best quality products At BOROUN, WE faithfully supply you with the good service and high-grade products you need.
Difference between ERW, SSAW, LSAW. Steel pipe for pipe technology, can be divided into (SML), mainly as the Oilfield internal transportation pipeline and small-diameter high-pressure natural gas pipeline, used for a small number of long-distance gas pipeline, the vast majority of long-distance pipeline with Direct seam high frequency (ERW), spiral submerged arc (SSAW), LSAW three (LSAW).
Coating pipe base metal is including spiral, straight seam pipe, seamless steel pipe, etc which, are widely used in pipeline projects in the field of petroleum, chemical natural, gas, heating, sewage, treatment, water, bridges, steel structures, piling and other marine water. 2) StandardDIN 30670:Polyethylene coatings of steel pipes and fittings.
The annual yield of SSAW pipe with outside diameter 219mm-3620mm, wall thickness 5-25.4mm and steel grade B-X80 is 1,000,000 tons. its two steel pipe production lines, one for spiral submerged arc welded (SAW) steel pipe and one for longitudinal submerged arc welded (SAW) steel pipe, are respectively comprised of two sets of main machines and 1
The surface quality of ERW pipes are better when compared to SAW (LSAW, SSAW) pipes, as they are smooth and have a better finish. In most of the SAW pipes, it is mainly about the weld reinforcement internally and externally.
API 5L Spec Line pipe Comparison and Selection-LSAW and SSAW
Due to mechanical expanding process, UOE pipe has higher dimensional accuracy than SSAW. SSAW pipe weld length is longer than the UOE pipe, it also has higher probability of weld defects. UOE separately forming and welding, good welding position, welding parameters easy to control, easy to weld quality assurance.

Difference of LSAW,ERW and SSAW - Hunan Great Steel Pipe
More common steel pipe is SSAW – spiral welded pipe. High frequency straight seam (ERW) according to the welding process is divided into different induction welding and resistance welding two forms, based on hot rolled wide volume as raw material, through the continuous forming, bending, welding, heat treatment, sizing, straightening, cutting process.
