We're well-known as one of the leading longitudinal weld erw, saw, dsaw, efw steel pipes manufacturers and suppliers in China. Please feel free to buy bulk longitudinal weld erw, saw, dsaw, efw steel pipes made in China here from our factory.(plate) Difference between ERW, SSAW, LSAW the professional manufacturer of LSAW (JCOE) pipe, Size from DN400~DN1500*6MM~60MM, Standard according to API 5L PSL1 &PSL2/ASTM /DIN/JIS /EN/AS and so on. Read More.(plate) ERW/LSAW Welded Steel Pipe (steel) SSAW pipe full name is Spiral Submerged arc welding pipe. The pipe is formed by spiral submerged arc welding technology which is called SSAW pipe. Generally speaking, when it comes to the same standard and steel grade, the price of SSAW pipe is cheaper or lower than ERW pipe and LSAW pipe. The strength is higher than the straight seam welded pipe.
LSAW and HSAW are variants of SAW (submerged arc welded) pipes. The difference between them is the way they are welded. In LSAW pipes, the welding is longitudinal, which means that steel (hot rolled coil plate) is rolled into a pipe and the seam is welded longitudinally. In the HSAW type, steel coils are welded spirally, like a helix, so that ssaw lsaw erw weld black steel(plate) SSAW Steel Pipe vs. LSAW Steel Pipe 1 YRS. 96.5%. 5.0 (3) Contact Supplier. 1/6. double seam black welding astm a252 gr.2 ssaw steel spiral pipe,spiral water pipe ssaw lsaw erw weld black steel API 5L X-65 Psl2 Spiral Weld Tube SSAW LSAW ERW Carbon Steel Line ssaw lsaw erw weld black steel
It is using the same welding technology of Submerged Arc-Welding with LSAW Pipes. 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, forming and welding, sot he welding seam is in a ssaw lsaw erw weld black steel(plate) Welded steel pipe Welded steel pipe(steel) Difference between ERW, SSAW, LSAW; The difference between ERW steel pipe and SAW stee ssaw lsaw erw weld black steel API SPEC 5L standard specifies; Spiral submerged-arc welding pipes; ASTM A53 Standard Specifications; ASTM A252-89 Welded and seamless steel pipe piles; ASTM A500, carbon steel, cold formed welded and se ssaw lsaw erw weld black steel ERW Black Steel Pipe; Applications of Welded ssaw lsaw erw weld black steel(plate) ssaw lsaw erw weld black steel(steel) erw steel pipeerw steel tubeerw welding
SSAW steel pipe, spiral submerged arc welded pipe is coiled its forward direction and shaping of the center line of the pipe forming angle (adjustable), side shaping welding edge, the weld into spiral line, the advantage of the same specifications can produce a variety of diameter specifications of steel, raw adaptation range is larger, weld joint can avoid the principal stress, stress better.
