Product Range

Our Standard Production Range

We classify our pipes according to the method of manufacture:

  1. High Frequency Induction (HFI) Pipes: Small diameter pipes manufactured using the longitudinal high frequency induction seam weld process – DN80mm – 200mm.
  2. Spiral Weld Pipes: Medium and large diameter pipes manufactured using the submerged arc spiral weld process – DN250mm – 2000mm.

Typical dimensions

  • Outside diameters: 88.9mm to 2032mm (up to 2540 mm on request)
  • Pipe lengths: 6m to 12m (longer on request)
  • Wall thicknesses: 2.3mm to 16mm – depending on steel grade (steel grades and wall thicknesses from 16mm to 20mm on request)
