ASTM A252 Large Diameter SSAW Spiral Welded Pipe For Oil And Gas Transmission Pipelines
What is Spiral Welded Steel Pipe
Spiral welded steel pipe is a type of steel pipe that is manufactured by rolling a strip of steel into a cylindrical shape and then welding the edges together to form a spiral seam.

(4)Offshore and onshore construction
(5)Industrial plant piping
(6)Mining and dredging operations
Advantages
(1)Cost advantage: Large-diameter steel pipes can be made from narrower strip steel, with adjustable spiral angles and pitches. This allows for multi-specification pipes from fixed-size strips, offering high flexibility and low costs.
(2)Good pressure-bearing capacity: The spiral weld distributes stress more evenly under internal pressure, allowing for thinner walls compared to straight-seam welded pipes at the same pressure, enhancing safety.
(3)Excellent weldability: Using hot-rolled coils as raw material results in lower alloy content, improving weldability and providing better crack resistance than straight-seam steel pipes.
(4)Regular pipe shape: Consistent production processes ensure precise geometric dimensions, excellent pipe mouth ovality, and end face verticality, facilitating high-accuracy assembly during on-site welding.
Packaging and Shipping
We use standard export packing to safely transport welded steel pipes, protecting them from damage during transit. For shipping, we offer multiple options: containerized sea freight for long - distance international shipments, bulk sea freight for large orders, air freight for urgent needs, land transportation for domestic or nearby destinations, and multimodal transportation for maximum efficiency.
