Longitudinal Straight Seam Welded Steel Pipes

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 Longitudinal Straight Seam Welded Steel Pipes

As the name shows, longitudinal pipe has a straight welding seam on the pipe surface. Different from the longitudinal pipe, the welding seam of which is vertical to the axial line of the pipe, helical welded pipe is rolled and welded according to certain helical angles. What are spiral pipes?What are spiral pipes?Spiral pipe is used in industry, also known as spiral steel pipe or spiral welded pipe, and it is to roll the low carbon structural steel and low alloy steel strip to tube according to certain helix angle, and then welded pipe joints.The Difference Between the Straight Seam Welded Pipe and Longitudinal Straight Seam Welded Steel Pipes
