Longitudinally welded tubular hollow sections

Longitudinally welded tubular hollow sections are manufactured from steel plate by using various bending methods to form a tube. This method of fabrication is suited to high value added heavy wall or large diameter structural and non-structural applications.

Size range:

  • Outside diameter up to and greater than 3000mm
  • Wall thickness up to 80mm (heavier on request)
  • Unspliced length up to 16m

Characteristics and key benefits:

  • Wide range of steel grades and manufacturing standards available
  • Heavy wall
  • Option to incorporate:
    • pile shoes to facilitate pile driving
    • internal lining and external protective coatings
    • clutches, shear key rings or other fabricated components

Typical applications:

  • Pipes – typically used in pipelines for conducting liquid or gas
  • Piles – bearing elements for foundations typically within civil and marine environments
  • Casings for concrete piles
  • Components within mechanical systems and high pressure / temperature processes
  • Oil & petroleum casings
