FEATURES OF LSAW PIPE SYSTEM

                                        •    

  • Welding under static conditions
  • High weld quality, short welds, 
  • Probability is very small defects. Near zero defects
  • By expanding full-length steel tubular good, precise size, wide range of pipe wall thickness and diameter range, the diameter range up 16-60 inch wall thickness range up 6.0-35mm
  • High degree of automation. CNC controlled.
  • Lower production costs compared to other methods
  • High flexibility and quick change over within the whole production range 
  • High reliability and availability, featuring economies that keep investment at a minimum 
  • High production line utilisation rate and material yield 
  • Maximised production capacity and low maintenance 
  • Less capital spare parts and low operation cost 
  • Easy operation for mass production

LSAW PRODUCTION ADVANTAGES

  • It uses leaflets plate as raw material. Can also use Steel Coil
  • A wide range of the finished product specifications, 
  • weld toughness, ductility, uniformity and dense, with a large diameter, wall thickness, high pressure resistance, low-temperature corrosion resistance, etc.. 
  • Required steel pipe in the construction of high-strength, high toughness, high-quality long-distance oil and gas pipelines, mostly large diameter thick wall LSAW Steel Pipes 
  • Used extensively in construction Industry 
  • Used in low/ high pressure Water and Agricultural Irrigation Projects
  • Used in foundations for high rise buildings, bridges, dams, onshore & offshore platforms and other steel bearing with columns, large span structures as well as wind and seismic requirements for electrical tower mast structure.
