Spiral steel pipes for steam transportation are formed using externally controlled or internally controlled rollers. Chinese name Spiral steel pipe for steam transportation Steel pipe category *-*
Pipe standard
Spiral steel pipe for steam transportation adopts external control or internal control roller forming. Production process Before forming: after smoothing, trimming, planing, surface cleaning, conveying and pre-bending. During forming: a weld gap control device is used to ensure that the weld gap meets the welding requirements, pipe diameter, offset amount and welding After the seam gaps are strictly controlled and formed: use an air plasma cutting machine to cut the steel pipes into individual steel pipes. After cutting into individual steel pipes, the first three dredging steel pipes of each batch must undergo a strict first inspection system to check the mechanical properties of the welds. Chemical composition, fusion status, steel pipe surface quality and non-destructive testing to ensure that the pipe making process is qualified can be officially put into production and undergo a hydrostatic test. The pressure adopts radial sealing. The test pressure and time are detected by the steel pipe hydraulic computer. The device is strictly controlled. Test parameters are automatically printed and recorded. Steel pipe category: *-*-Pipe material:
