Spirally Welded

Spirally welded pipes

Spirally welded pipes are pipes where the weld runs across the pipe as a spiral. A coil is rolled out and formed into a pipe-shaped spiral. It is then completely spirally welded. This is a continuous welding process until the coil is unwound. This is the ideal production form for larger projects/bigger quantities with long pipes and relatively thin wall thicknesses.

Spirally welded pipes are very suitable for various constructions as; combined walls , (outrigger) pipes, mooring posts/fenders and guideways.
