pipe longitudinal weld

Can helical welding be used to make pipe?Can helical welding be used to make pipe?Once the steel is cut for rolling, it cannot be changed, which means the diameter of the longitudinal pipe is fixed. While for helical welding, it can achieve various diameters of pipes by rolling the steel plate with different angles. Thus, helical welding can be used to manufacture pipes of different diameters.Helical Welded Pipes and Longitudinal Welded Pipes FeedbackDifference between helical welded pipes and longitudinal pipe longitudinal weld

As for longitudinal welded pipes, to meet the required length of pipelines used in industry projects, short longitudinal pipes always need to be jointed and welded into a long enough pipe. Thus, inevitably, many T-shaped welding seams would appear in this welding process, largely increasing the possibility of welding defects.

What is helical welding?What is helical welding?While for helical welding, it can achieve various diameters of pipes by rolling the steel plate with different angles. Thus, helical welding can be used to manufacture pipes of different diameters. It can use narrower steel to manufacture pipes into large diameter using large helical angle.Helical Welded Pipes and Longitudinal Welded Pipes49 CFR § 192.113 - Longitudinal joint factor (E) for steel pipe longitudinal weld

The pipe ovality, i.e. the deviation from an ideal round shape results from a non-perfectly round bending of the plate and from the distortions caused by the longitudinal weld. Moreover, the residual stresses in the pipe cause a shape change when the pipe is cut in shorter pieces.Throughout Simulation of Manufacturing of The pipe ovality, i.e. the deviation from an ideal round shape results from a non-perfectly round bending of the plate and from the distortions caused by the longitudinal weld.
