Seamless Steel pipe (SMLS) is formed by drawing a solid billet over a piercing rod to create the hollow shell. The manufacturing process does not include any welding.

  • Use extrusion mother pipe In-Exterior surface profiles are beautiful due to drawing process.
  • No welding part, widely use in high pressure required field.
  • Equal phase exist on whole mother pipe due to HAZ (Heat Affection Zone)
  • When internal pressure increases by angle of banding, it tolerates longer than welded pipe. No nurst from weld zone.

Seamless Tube

Applications

Widely used in power plants, petrochemical plants, boiler and heat exchanger, shipbuilding, semiconductor equipment, high temperature, high pressure, high purity environment.
