The National Standard Allowable Deviation Wall Thickness of the Spiral Steel Pipe

Jun. 05, 2018

Spiral Steel Pipe is not only safe and healthy, but also with high strength and good corrosion resistance. Now is widely used in water supply and drainage pipeline, liquefied petroleum gas transportation and construction pile driving etc.

There will appear error in the production process. But the error cannot be too large, it must be in a certain range. Or there will affect the daily use. Then what is the national standard allowable deviation wall thickness of the spiral steel pipe ?

The national standard allowable deviation of wall thickness is between 0.2mm and 0.6mm. In the forming process, the steel plate deformation is uniform, the residual stress is small, and the surface does not produce scratch. Machined spiral steel pipes have greater flexibility in diameter and thickness dimensions.
