SSAW Steel Pipe Manufacturer – Carbon Steel Spiral Welded Pipe Supplier
We are a professional SSAW steel pipe manufacturer in China, specializing in carbon steel spiral welded pipes (SSAW pipes) for oil & gas pipelines, water transmission systems, piling foundations, and structural applications. Our products are manufactured in compliance with API 5L, ASTM A252, and EN standards, covering a wide range of diameters and wall thicknesses to meet global engineering requirements.
What is SSAW Steel Pipe?
SSAW (Submerged Arc Welded) steel pipe, also known as spiral welded steel pipe, is produced by rolling steel strips into a spiral shape and welding the seam using submerged arc welding technology. It is widely used for large-diameter pipelines due to its high strength, cost efficiency, and flexibility in production length and diameter.
