Spirally Welded Tubular Hollow Sections
DESCRIPTION

Spirally welded tubular hollow sections are manufactured from steel coil by using a continuous spiral weld, welded internally and externally using automatic submerged arc welding. This method of fabrication is often the most economical solution for medium to large size structural and non-structural applications.

 

TYPICAL APPLICATIONS

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
KEY BENEFITS & FEATURES
  • Wide range of steel grades and manufacturing standards available
  • In-line manufacturing process for pile forming, welding and testing
  • Fast and cost-effective manufacturing method
  • Continuous unspliced sections
  • Option to incorporate:
    • pile shoes to facilitate pile driving
    • internal lining and external protective coatings
    • clutches, shear key rings or other fabricated components
