The two types of pipes produced through these technologies are Longitudinal submerged arc welded (LSAW) and Spiral submerged arc welded (SSAW) pipes. LSAW are made by bending and welding wide steel plates and most commonly used in oil and gas industry applications. Due to their high cost, LSAW pipes are seldom used in lower value non-energy
The most common variations of submerged arc welding pipes are:LSAW (longitudinal welding), DSAW (double submerged arc welding, the weld is applied on both the inner and outer surface) and SSAW or HSAW (spiral welded pipe, generally used for water transmission and distribution but Best Welded Steel Pipes In China - JS - China Leading Does Spiral welded pipe?

The only difference in their manufacturing process is that SSAW pipe is spiral welded while the LSAW pipe is longitudinally welded. The manufacturing process is rolling the steel strip, to make the rolling direction have an angle with the direction of the pipe center, forming and welding, so the welding seam is in a spiral line. The LSAW pipe Difference Between LSAW and HSAW Pipes - Knowledge Difference Between LSAW and HSAW Pipes. Helical submerged arc welding (spiral) steel pipe is the full name of HSAW pipe. spiral welded pipe and straight seam welded pipe welding method is consistent, straight seam steel pipe, inevitably, there will be a lot of the t-shaped weld, so the probability of weld defects is also greatly improved, and
Dec 19, 2018 · SAW pipe means Submerged Arc Welded pipe. And from different weld seam, there are two saw pipes, including LSAW and SSAW. As the name suggests, SSAW has a spiral weld seam. And LSAW has a longitudinal weld seam. ERW Steel Pipe, LSAW Steel Pipe, SSAW Steel Pipe, Hunan LSAW Steel Pipe.

Besides LSAW pipes we can also supply carbon steel ERW pipes, spiral welded pipes, seamless steel pipes & fittings, stainless steel tubes etc. for your diversified requirements by one-stop servie. 1, Sizes:323mm - 1820mm LSAW, SSAW, and ERW Pipes Description and ComparisonMay 06, 2020 · LSAW Pipes has two types:Longitudinal (Single or Double Straight-seam Weld, DSAW) and Spiral (also called SSAW, HSAW, or SAWL). What makes DSAW pipes differ from other LSAW pipes is that DSAW have a seam weld in the inside and outside of the pipe, while the latter have a single seam weld on the outer surface, longitudinal or cross sectional.
1. ASTM A53 spiral steel pipe 2. Large Welded Steel Pipe 3. 54inch*9.52Spiral steel pipe are producing 4. 36 inch Spiral Submerged-Arc Weld steel pipe (4) 5. 457mm OD LSAW steel pipe SSAW Steel PipeSSAW Steel Pipe Competitive Advantages. 1) As long as the forming angle is changed,steel pipes of various calibers can be produced with strips of the same width,which is easy to adjust. 2) Because it is formed by continuous bending,the length of helical tube is not limited and can be determined at will. 3) The spiral shape of the weld is evenly
Stainless and galvanized lsaw weld pipe for industrial and commercial purposes at . These hot-dipped lsaw weld pipe are ideal for seamless construction uses. The difference between SSAW,ERW and LSAW(UOE)Jan 11, 2018 · According to the manufacturing process of steel pipe, seamless steel pipe can be divided into (SML), as the main oil gathering pipe and the small caliber high pressure natural gas pipeline, the number for the long oil pipeline is very few, most of the pipeline is the use of high-frequency welded pipes (), spiral submerged arc welding pipe (SSAW) and LSAW (LSAW) three.
Spiral submerged arc welding (SSAW) steel pipe,also called HSAW pipe,welding line shape like a helix.It is using the same welding technology of Submerged Arc-Welding with LSAW pipe.Differently SSAW pipe is spiral welded where the LSAW is longitudinally welded.Manufacturing process is rolling the steel strip,to make the rolling direction have an angle with the direction of the pipe center Longitudinally Submerged Arc Welded Steel pipes, LSAW LSAW (Longitudinal double submerge arc welding) carbon steel pipe is a type of SAW pipe made of steel plates that were hot rolled by JCOE or UOE forming technology.
