Spiral Welded Pipe - an overview ScienceDirect Topics

Spiral-welded pipe is produced from coils of steel that are unwound and flattened. The flattened strip is formed by angled rollers into a cylinder of the desired diameter. Interior and exterior SAW seal the spiral seam. At the end of the coil, a new coil is butt-welded to the trailing edge of the pipe, forming a cross seam. Spiral Weld Pipe Specifications and Grade Chart - Feb 03, 2018 · Carbon Steel Spiral Welded Tubes are used in onshore and offshore oil and gas Tubelines that require critical service, high performance and tight tolerances. Carbon Steel Spiral Welded Tubes are also being used for low pressure liquid delivery, such as gas, water, and oil.
