Overview of ASTM A139 Spiral Welded Pipe
ASTM A139 Spiral Welded Pipe is a standard specification for electric-fusion (EFW) welded steel pipes designed for low-pressure and structural applications. These pipes are mainly used in water transmission, drainage systems, structural piling, and industrial piping.
The ASTM A139 standard, issued by the American Society for Testing and Materials (ASTM), ensures that these pipes comply with strict dimensional, mechanical, and quality requirements. Unlike ASTM A252, which is primarily for piling applications, ASTM A139 is designed for fluid transport and structural use.
Key Features of ASTM A139 Spiral Welded Pipe
✔ Manufactured using the Electric Fusion Welding (EFW) process
✔ Available in large diameters up to 3500mm
✔ Suitable for low-pressure fluid and gas transmission
✔ Cost-effective compared to seamless pipes
✔ Can be internally and externally coated for corrosion resistance
In this guide, we’ll explore everything about ASTM A139 Spiral Welded Pipes, including manufacturers, specifications, price trends, coatings, applications, and welding processes.
