Spiral Welded Pipe vs Longitudinal

• As the name suggests, the manufacturing processes of spiral welded pipe and longitudinal welded pipe are distinctly different. While Spiral-weld pipes are rolled and welded according to a preferred helical angle, the longitudinal welded pipes are created by bending and forming metal, and finally welded together down the length of the pipe to create a straight, longitudinal seam.
• Spiral welded pipes are produced using a continuous process under stable working conditions. On the other hand, the manufacturing of longitudinal welded pipes is carried out in stages.
• Longitudinal pipes are normally preferred for smaller-diameter applications whereas spiral welded pipes are best for applications requiring large-diameter pipes with thinner walls.
