Submerged arc spiral welded products
Steelpipe submerged arc spiral welded (SSAW) steel pipe is ideal for use in structural applications, such as foundation work (pile casing or piling) and in wharf, bridge and building construction projects because it offers major advantages over alternative materials.
The spiral forming process produces accurately manufactured pipe that makes the product easy to use and, combined with high-quality welding and testing, ensures enduring dependability.
Flexibility in end-preparation means that the closure plates, cone points, driving shoes and crosses are all compatible with spiral-welded steel pipe. As an alternative, pipes can be driven open-ended where minimum soil displacement is desired.
Efficient splicing on-site due to the consistent circularity of pipe ends and tight tolerances of diameters. Moreover, piles can be easily spliced to extend the pile length, which is a requirement for deep driving. Numerous combinations for jointing systems (including machine-bevelled ends) are available to guarantee fast, accurate jointing in the field. Internal welding bands, supplied loose or tack-welded into one end of the pipe, can also be employed to align piles for jointing and provide backing for welding.
Variable lengths can be manufactured to suit ground conditions and changing driving depths to minimise on site welding.
