Large-diameter Spiral Submerged Arc-Welding Pipe Market As per trusted projections, the Large-diameter Spiral Submerged Arc-Welding Pipe market is expected to accrue notable returns, expanding with a CAGR of XX% during 2021-2026. The research document also illuminates the shares and size of the sub-markets across the various geographies.
Submerged arc welding (SAW) is generally the preferred method for joining the seam edges of large diameter spiral pipes. The quality control of the welded pipes usually consists of a hydrostatic test in which water is pumped into the pipe. High pressure hydrostatic tests can moderate tensile residual stress caused by the welding process.
SPIRAL PIPE CASING - Alberdo Industries - The Philippines Spiral Submerged Arc Welded or SSAW pipes are highly noticeable because of their helical welding seam. Spiral steel pipe casing, which is also called pipe piles and bored pipe casing, is normally used in the foundation of structures that have soft soil. These pipes can also be used in water lines that require big diameter and lengths.
Spiral Welded Pipe Manufacturing ProcessSpiral welded pipe unit The spiral welded pipe unit is used to produce large-diameter steel pipes with a diameter of (892450)mm× (0.525.4)mm and a length of 635m. The production method is continuous and discontinuous. The unit adopts spiral forming, and the welding adopts two steps of pre-welding and final welding.
