  • 1000mm large diameter lsaw carbon steel pipe thick-walled steel tube LSAW steel pipe for construction
    LSAW steel pipe (Longitudinally Submerged Arc Welding abbreviated  is a professional expression term for LSAW steel pipe. It uses a single medium and thick plate as the raw material, and the steel plate is pressed (rolled) into a tube blank in a mold or a forming machine. The pipe is produced by submerged arc welding and expanded diater. In the construction of high strength, high toughness and high quality long-distance oil and gas pipelines, most of the steel pipes required are large-diameter thick wall straight seam submerged arc welded pipes.
  • API 5L gr.b ssaw spiral welded steel pipe
    SSAW steel pipe is the raw material of strip coil, often temperature extrusion molding, automatic double-wire double submerged arc welding process made of spiral seam pipe. Spiral steel pipe will strip into the pipe unit, the multi-roll rolling, strip rolled up, forming a circular gap opening gap, adjust the squeeze roll reduction, the weld gap control in the 1 ~ 3mm, and make both ends of the weld flush.
  • Astm A252 Ssaw Carbon Welding Pipes Custom Large Diameter 480mm Structure Welded Steel Pipe
    SSAW steel pipe is the raw material of strip coil, often temperature extrusion molding, automatic double-wire double submerged arc welding process made of spiral seam pipe. Spiral steel pipe will strip into the pipe unit, the multi-roll rolling, strip rolled up, forming a circular gap opening gap, adjust the squeeze roll reduction, the weld gap control in the 1 ~ 3mm, and make both ends of the weld flush.
  • ASTM A36 LSAW SSAW steel pipe large diameter API5L 5CT oil and gas for sch 40 carbon steel ERW spiral welded pipe tube
    LSAW steel pipe (Longitudinally Submerged Arc Welding abbreviated  is a professional expression term for LSAW steel pipe. It uses a single medium and thick plate as the raw material, and the steel plate is pressed (rolled) into a tube blank in a mold or a forming machine. The pipe is produced by submerged arc welding and expanded diater. In the construction of high strength, high toughness and high quality long-distance oil and gas pipelines, most of the steel pipes required are large-diameter thick wall straight seam submerged arc welded pipes.
  • Carbon Steel LSAW ERW X65 X70 X80 BS 1139 Mild Welded Casing LSAW Carbon Steel Pipe
    LSAW steel pipe (Longitudinally Submerged Arc Welding abbreviated  is a professional expression term for LSAW steel pipe. It uses a single medium and thick plate as the raw material, and the steel plate is pressed (rolled) into a tube blank in a mold or a forming machine. The pipe is produced by submerged arc welding and expanded diater. In the construction of high strength, high toughness and high quality long-distance oil and gas pipelines, most of the steel pipes required are large-diameter thick wall straight seam submerged arc welded pipes.
  • ERW Iron Pipe Welded Steel Pipe Round Erw LSAW Black Carbon Steel Pipe
    High-frequency resistance welding steel pipe, welding pipe and ordinary welding process is not the same, the weld is made of the base metal melt from the body, the mechanical strength is better than the general pipe. Smooth appearance, high precision, low cost weld high and small, favorable 3PE anti-corrosion coating. There are significant differences in the welding methods between high frequency welded pipe and submerged arc welded pipe. As the welding is done instantly at high speed, the difficulty of ensuring the quality of welding is much higher than that of submerged arc welding.
  • ERW Steel Pipe, ERW Casing, ERW Carbon Steel Pipe, MS ERW Pipe, GI ERW Pipe, Stainless ERW Pipe
    High-frequency resistance welding steel pipe, welding pipe and ordinary welding process is not the same, the weld is made of the base metal melt from the body, the mechanical strength is better than the general pipe. Smooth appearance, high precision, low cost weld high and small, favorable 3PE anti-corrosion coating. There are significant differences in the welding methods between high frequency welded pipe and submerged arc welded pipe. As the welding is done instantly at high speed, the difficulty of ensuring the quality of welding is much higher than that of submerged arc welding.

  • SSAW Steel Pipe Concrete Spiral Welded for Boiler Pipe Application
    SSAW steel pipe is the raw material of strip coil, often temperature extrusion molding, automatic double-wire double submerged arc welding process made of spiral seam pipe. Spiral steel pipe will strip into the pipe unit, the multi-roll rolling, strip rolled up, forming a circular gap opening gap, adjust the squeeze roll reduction, the weld gap control in the 1 ~ 3mm, and make both ends of the weld flush.
  • Straight seam welded steel pipe(lsaw steel pipe)
    LSAW steel pipe (Longitudinally Submerged Arc Welding abbreviated  is a professional expression term for LSAW steel pipe. It uses a single medium and thick plate as the raw material, and the steel plate is pressed (rolled) into a tube blank in a mold or a forming machine.
