ASTM A36 Spiral Welded Pipe – Cost-Effective Structural & Fluid Transport Solution
Product Name：ASTM A36 Spiral Submerged Arc Welded (SSAW) Pipe
Product Introduction
The ASTM A36 spiral welded pipe is manufactured from hot-rolled steel coil conforming to ASTM A36 standard, using the Spiral Submerged Arc Welding process. As one of the most widely used carbon structural steels, A36 offers excellent weldability, good ductility, and high cost-effectiveness, making it an ideal choice for large-diameter structural and low-pressure fluid pipelines.
our products Key Features
Reliable Mechanical Properties
Yield strength ≥250 MPa, tensile strength 400–550 MPa, elongation ≥20%, ensuring robust structural performance.
Excellent Weldability
Tight chemical composition allows easy field welding and secondary fabrication.
Spiral Forming Technology
Wide diameter range from 219 mm to 3020 mm, uniform wall thickness, optimized weld stress distribution, and high crack resistance.
Economical & Efficient
Lower cost compared to seamless or straight seam welded pipes of the same size, especially for large diameters and long-distance applications.
