Longitudinal Submerged Arc Welding (LSAW) Processes In LSAW pipe mills, processing is carried out by cold forming heavy carbon steel plates, the pipe prematerial on which many of the pipe properties depend. The material of LSAW steel pipe is unit middle or heavy thickness sheet, coiled in the molding or forming machine, welded by double submerged arc welding and expand the diameter. Process Difference between Spiral Steel Pipe and Straight Nov 10, 2020 · It can be divided into straight seam welded pipe (ERW, LSAW) and spiral welded pipe (SSAW). Spiral steel pipe is a spiral seam steel pipe made of strip steel coils as raw materials, often extruded and formed by automatic double-wire double-sided submerged arc welding. The spiral steel pipe feeds the strip steel into the welded pipe unit.
Spiral Submerged-arc Welded Quality Assurance. Spiral welded pipe production by submerged arc method is based on using tandem welding technique for joining inside and outside coil edges, which have been trimmed and beveled by carbide milling for high quality weld structure. SSAW Pipes, Spiral submerged-arc welding pipes,Spiral Spiral Submerged-arc Welded steel pipe technological process. Spiral welded pipe production by submerged arc method is based on using tandem welding technique for joining inside and outside coil edges, which have been trimmed and beveled by carbide milling for high quality weld structure. SSAW Steel Pipe - Threeway SteelThreeway 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 enabels to produce finely pre-welded SAWH steel pipe of 360000 tons per year,and we have become the leading enterprise in this industry in virtue of large productivity and advanced technical equipment.

Seamless Pipe|Hot Rolled/Cold Drawn Steel Pipe|Oil Casing CSPG has an annual output of 600,000 tons of spiral steel pipes, 300,000 tons of LSAW, and 200,000 tons of seamless steel pipes. CSPG has thirteen sets of SSAW pipe production lines, primarily producing double-faced submerged-arc welded pipes of diameters 159-3500mm, wall thickness 5-28mm, and material gradesQ235AB, Q345, L245, L360, and X42 Spiral Welded Steel Pipe Philippines SSAW/HSAW Pipe Spiral welded steel pipe is a low carbon carbon structural steel or a low alloy structural steel strip rolled into a tube blank with a certain helix angle (also called forming angle), and then welded and made into a pipe joint, which can use a narrow strip steel production of large diameter steel pipes.. Spiral welded pipes are single-sided welded and double-sided welded.
As ERW steel pipe and SAW steel pipe in the pipe during forming, welding and process is different, so that two kinds of steel pipe in the performance there are some differences. ERW steel pipe surface quality is superior to spiral submerged arc welded pipe, ERW steel pipe surface is smooth, smooth, beautiful, SAW steel pipe internal and Welded steel pipe:Spiral submerged-arc welding pipesSSAW 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.
