Spiral welded pipe.

Compared with the straight seam welded pipe, the spiral welded pipe has higher strength and larger diameter. The production standard of the spiral welded pipe is more than that of the straight seam welded pipe. Mainly used in steel structure engineering, machinery manufacturing, construction water, oil pipelines and other low-pressure fluid pipelines, and can also be used in piling,structure and other construction fields.

 

 

1. Package with 20 ft or 40 ft container, fixing spiral steel pipe in the container with steel cable;
2. Package in bulk;
3. Pieces per container depending on the diameter of spiral steel pipes.
4.According to customers' requirement.
Advantages of spiral welded pipe.
(1) Steel pipes of different diameters can be produced using strip steel of the same width, and
steel pipes of large diameter can be produced from narrow strip steel.(2) Under the same pressure conditions, the stress of the
spiral welded seam is smaler than that of the straight seam, which is 75% to 90% of that of the straight seam welded pipe, so t can withstand greaterpressure. Compared with the straight seam welded pipe of the same uter diameter, the wal thickness can be reduced by 10% to 25% under the same
pressure3) The size is accurate. the oenera diameter tolerance does not exceed 0.12%,.the delection is ess than 12000. and the ovalitv is less than 1%
Generally, the sizing and straightening process can be omitted.(4) Continuous production is possible. ln theory, long steel pipes can be produced. with small head and tail loss. and canincrease the metal utilization rate by 6% to 8%.
(5) The eouipment is ioht in weioht and ow initial investment. t can be made into a trailer-ype mobie unit to directly produce welded pipes at the
construction site where the pipeline is laid.


The production of   spiral welded steel pipes  can reflect the advantages of high quality and high efficiency. The production capacity of one spiral welded pipe unit is equivalent to 5-8 sets of straight seam welded pipe equipment. How to make multiple pipe coiling equipment production lines meet the same production standard, that is, produce according to a unified production process specification and quality assurance system to meet welding quality Requirements and piping manufacturing grades will be an  arduous task.
