Spiral Welded Steel Pipes SSAW
Spiral Submerged-Arc Welded Steel Pipes
SSAW Steel Pipe (Spiral Submerged Arc Welded) is manufactured using the spiral welding process, where hot-rolled steel coils or narrow steel strips are continuously shaped into a cylindrical form and welded along a spiral seam. This manufacturing method allows to produce steel pipes of large-diameter, making SSAW pipes ideal for oil and gas, pipeline transportation systems, piling, and structural applications.
The spiral welded structure provides excellent mechanical properties and efficient material usage, ensuring high strength and reliability. These pipes are commonly used in gas transportation, liquid transportation, and large-scale pipeline infrastructure projects.
Advantages of Spiral Welded Steel Pipes:
- High Structural Integrity – The spiral welding process provides strong mechanical performance and load-bearing capacity.
- Large Diameter and Versatility – SSAW pipes can be manufactured in various sizes, making them suitable for the oil and gas sector and natural gas infrastructure. They can also be used as welded structural hollow sections in construction.
- Efficient Production – SSAW pipes are manufactured from hot-rolled steel coils or narrow-strip steel, maximising material efficiency and reducing production costs.
- Enhanced Corrosion Resistance – To ensure long-term durability in harsh environments, spiral welded steel pipes can be supplied with hot-dip galvanising, external protective coatings, or specified elevated temperature properties.
- Strong Seam Welding – Using spiral submerged arc welding (SSAW) technology, the weld seam is highly uniform and secure, minimising risks of air holes or structural weaknesses.
