Spiral steel pipe, also known as spiral welded pipe or SSAW (Spiral Submerged Arc Welded) pipe, is a steel pipe formed by continuously welding a steel coil into a spiral shape.
Spiral steel pipe, also known as spiral welded pipe or SSAW (Spiral Submerged Arc Welded) pipe, is a steel pipe formed by continuously welding a steel coil into a spiral shape. With smooth inner walls, strong welding seams, and excellent pressure-bearing capacity, it is widely used in water supply systems, oil and gas transportation, structural engineering, and piling projects.
Spiral steel pipes offer stable mechanical performance, high tensile strength, and good weldability. Their spiral welding structure provides uniform stress distribution, making them ideal for long-distance pipeline transport. They can be produced in large diameters with flexible wall thickness options, ensuring suitability for various industrial and construction applications. In addition, the pipes can be coated or galvanized for enhanced corrosion resistance in harsh environments.
Common applications include municipal water pipelines, oil and gas pipelines, dredging lines, steel structure columns, bridge piles, and foundation support. With high durability, cost-effectiveness, and reliable performance,
spiral steel pipes remain a preferred material in major engineering and infrastructure projects worldwide.
