High Pressure SSAW Spiral Pipe for Oil Pipeline
Specifications
SSAW (Spiral Submerged Arc Welded) pipe is manufactured by helically forming and welding steel coil, offering a cost-effective solution for large-diameter applications. While suitable for many fluid transport services—including water, oil, and gas—its suitability for "high pressure" depends on the project's specific safety requirements. Engineers often prefer seamless or LSAW pipes for extreme high-pressure service due to their lower residual stress and shorter weld seams.

High Pressure SSAW Pipe Packing & Loading
→SSAW Pipe is transported in containers
(Nesting Packaging): Large-diameter SSAW pipes can be nested within one another, similar to Russian dolls, to utilize the internal space of larger pipes and minimize the volume of the cargo. This is a "game-changer" for reducing freight expenses and improving supply chain efficiency.
