Q235B、ASTM A36、SS400 spiral welded pipe for oil and gas transmission
What is Spiral Welded Steel Pipe
Spiral welded pipe is the low carbon structural steel or low alloy structural steel steel strip according to a certain Angle of the helix into the tube blank, and then welded the pipe joint made of it can be used to produce large diameter steel pipe with narrow strip steel. It offers higher strength and is often used for oil and gas transmission.

End Preparation: |
Available in plain end configuration or 30-degree beveled ends All pipe ends shall be burr-free and properly finished to ensure safe handling and optimal joint alignment. |
SSAW Spiral Welded Pipe Applications
(1)Oil and gas transmission pipelines
(2)Water and sewage pipelines
(3)Structural and piling purposes
(4)Offshore and onshore construction
(5)Industrial plant piping
(6)Mining and dredging operations
Advantages
(1)The use of strip steel of the same width can produce steel pipes of different diameters, especially narrow strip steel can be used to produce large diameter steel pipes.
(2)Under the same pressure conditions, the stress of the spiral weld is smaller than that of the straight seam, which is 75% to 90% of the straight seam welded pipe, so it can withstand greater pressure. Compared with the straight seam welded pipe with the same outer diameter, the wall thickness can be reduced by 10% ~ 25% under the same pressure.
(3)Continuous production, theoretically can produce infinite length steel pipe, cutting head, cutting tail loss is small, can improve the metal utilization rate of 6% ~ 8%.
(4)Compared with the straight seam welded pipe, its operation is flexible and the replacement variety is convenient to adjust.
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.
