Project Description

API 5L A53 Spiral Pipe

  • API 5L A53 Spiral Pipe

Spiral welded pipe: Longitudinal strength is generally higher than that, can narrow the billet production of large diameter pipe, you can also use the same width of the billet production of different pipe diameters. However, compared with the same length of straight seam pipe, weld length of 30 to 100%, and lower production rate. Therefore, smaller diameter pipe is mostly a straight seam welding, large diameter spiral welded pipe for the most part.

Spiral welded steel pipe: according to different welding methods can be divided arc welded pipe, high-frequency or low frequency electric resistance welded pipe, gas pipe, stove pipe, Bundy tubes.
