Classification and Production Methods of Steel Pipes

Jun 22, 2021 · When you purchase welded steel pipe from industrial pipe suppliers you would get a wide array of classification and pipes are produced using different methods Longitudinal Submerged Arc Welding (LSAW) Processes It is then made into a pipe by stretching the hot steel slab/billet out into a seamless pipe or forcing the edges of flat steel strip together and sealing them with a weld. When operational conditions require high wall thickness due to high internal or external pressures, LSAW (Longitudinal Submerged Arc Welding) pipes are commonly the most economical solution.

SSAW Steel Pipe - Threeway Steel

The SAWH steel pipe is the spiral submerged arc welding steel pipe for short. It is made adopting sumberged arc welding technique and comes with a welding seam. Threeway steel has overwhelming advantages over cometiotors in manufacturing this SAWH steel pipe.We have 10 traditional one-step production lines and 1 two-step production line that SSAW Steel Pipe, Spiral Submerged Arc Pipe, SAWL Steel Pipe45 rows · The spiral steel pipe feeds the strip steel into the welded pipe unit. After rolling by multiple Spiral Welded Steel Pipe Philippines SSAW/HSAW Pipe SSAW Pipe (Spiral Submerged Arc-Welding Pipe) also called HSAW pipe, welding line shaped like a helix. 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.

Steel Pipe & Circular Piles - Global Trade Sales AustraliaSMLS - Seamless Steel Pipe. SSAW - Spiral Submerged Arc Welded Steel Pipe. LSAW - Longitudinal Submerged Arc Welded Steel Pipe. ERW - Electric Resistance Welded Steel Pipe. 'C' - Cold formed sections. '250' - minimum yield strength in MPa. '350' - minimum yield strength in MPa. '450' - minimum yield strength in MPa. The difference between ERW steel pipe and spiral steel Jun 03, 2018 · Spiral steel pipe is a coiled steel pipe made from strip coils as the raw material, which is often warm extruded and welded by an automatic double wire double-sided submerged arc welding process. The strength of the spiral welded pipe is generally higher than that of the ERW welded pipe.

Spiral submerged arc welding(SSAW) is its forward direction and forming tube centerline hose reel molding angle (adjustable), side molding edge welding and weld them into a spiral. Spiral Submerged-arc Welded Quality Assurance; Submerged arc welding pipe, SAW pipes; ASTM A252 SSAW pipes; ASTM A252-89 Weldedd and seamless pipe piles; Spiral Submerged-arc Welded steel pipe spiral submerged arc welded ssaw steel pipe - Stainless and galvanized spiral submerged arc welded ssaw steel pipe for industrial and commercial purposes at . These hot-dipped spiral submerged arc welded ssaw steel pipe are ideal for seamless construction uses.Interpipe Inc. DSAW & Spiral Weld PipeDouble Submerged Arc Welded (DSAW) steel pipe is available in straight and spiral welded formats and used in a variety of applications. The submerged welding process protects the steel from contamination of impurities in the air. Both inside and outside welds are performed. DSAW pipe can be specified in very large diameter and to exact inside or outside dimensions.
