Summary
For projects requiring large-diameter steel pipes with flexible production and reasonable cost, spiral welded pipe is a reliable and widely accepted solution. Contact with Tianjin Youfa Steel Pipe Group, get free quotation and enquiry more about Youfa brand steel prodcuts for your project.
Spiral welded pipe is produced by spirally forming steel strip and welding along a helical seam around the pipe body. This manufacturing method allows greater flexibility in producing large-diameter steel pipes.
Spiral welded steel pipes are commonly used in Water transmission pipelines, Gas distribution systems, Steel pipe piles and foundation projects, Structural supports for large-span structures, Large-diameter low-pressure oil and gas pipelines
Spiral Welded Pipe Manufacturing Process
● Steel strip is formed at a specific spiral angle
● Continuous spiral forming creates the pipe shape
● Internal and external submerged arc welding is applied
● Fixed-length cutting, weld inspection, and hydrostatic testing
● Optional pipe expansion depending on requirements
By adjusting the spiral angle, the same strip width can be used to manufacture multiple pipe diameters.
Advantages and Limitations of Spiral Welded Steel Pipe
Advantages
High flexibility for large-diameter production
Efficient use of raw material
Lower equipment investment compared with LSAW pipe
Spiral weld distributes stress more evenly along the pipe
Limitations
Longer weld seam than straight welded pipe
Dimensional accuracy and roundness slightly lower
More complex residual stress distribution
Slower production speed
