Thick-walled spiral pipe wall thickness of steel pipe means with respect to ordinary spiral steel pipe spiral pipe slightly thicker. With respect to the advantages of ordinary spiral pipe wall thickness are: high strength, high impact strength, high safety performance, longer life

Thick-walled spiral pipe forming process

1. Spiral Pipe Forming ago

Double-sided spiral pipe submerged arc welding using advanced production process, welding may be implemented in the best position, not prone to the wrong side, partial and incomplete penetration weld defects, easy to control weld quality and position. Spiral steel pipe using a special welding process, welding can be achieved in the best welding position, without any errors defects, to ensure the eligibility of spiral steel pipe, good quality assurance.

2. Spiral Pipe Forming

Spiral pipe forming process, the steel sheet to be deformed even small residual stress, surface scratches do not produce, so I chose steel spiral pipe production to be careful, do not have to scratch the surface to be uniform. Spiral pipe machining diameter and wall thickness in a range of sizes greater flexibility, especially in the production of high-grade steel thick-walled pipes, especially small and medium-diameter thick-walled pipe connection, other processes have incomparable advantages, to meet users spiral pipe specifications more demanding.
