What other uses does spiral welded pipe have in water supply engineering besides traditional oil pipelines

Spiral welded pipes have low cost, excellent quality, and fast production speed. At present, preliminary progress has also been made in some special application directions, such as pier piling, tank welding (oil tanks, boilers, etc.), civil air defense engineering, air ducts, drums, steel structure support, pipes for high-rise building pile foundations, bridge type filter pipes, large diameter spiral circular variable square pipes, and so on. Spiral welded pipes are gradually being accepted by more and more industries due to their low cost, high level of production automation, and simple equipment structure. They will have great potential for development in the future.
