    Are welded pipes thinner than longitudinal?Are welded pipes thinner than longitudinal?Obviously, under same working pressures, the strength exposed to helical pipe is lower, thus, for pipes of same diameter, wall thickness of helical welded pipes could be manufactured thinner than longitudinal welded pipes. Once pipe pressure beyond its tolerance, the pipe would get burst.Helical Welded Pipes and Longitudinal Welded Pipes - OCTG pipe prod Is longitudinal welding better than helical welding?Is longitudinal welding better than helical welding?Besides, T-shaped welding joints incline to cause welding residual stress, which lays potential risk for future fatigue crack. Therefore, though having low cost and simple manufacturing technique, the overall performance of longitudinal welded pipe is less promising than the helical welded pipes.Helical Welded Pipes and Longitudinal Welded Pipes - OCTG pipe prod
