The difference between straight seam steel pipes and seamless steel pipes

The difference between straight seam steel pipes and seamless steel pipes

The main differences between straight seam steel pipes and seamless pipes are production technology and application. A straight seam pipe is an iron plate produced through processes such as bending, sealing, and welding, with one weld allowed. Seamless pipes, on the other hand, are produced by hot rolling round steel using a pipe rolling mill and have no welds.

A straight seam pipe is an iron plate produced through processes such as bending, sealing, and welding, with one weld allowed. Seamless pipes, on the other hand, are produced by hot rolling round steel using a pipe rolling mill and have no welds.

Straight seam steel pipes are made by curling steel strips and welding them. Seamless pipes have no welding gaps, and they are a complete circular steel pipe made directly from round steel and pulled out directly from steel billets. 

When the diameter and wall thickness of seamless pipes and straight seam pipes are equal, the pressure and strength borne by seamless pipes are much greater than those of straight seam pipes. Generally, seamless pipes are chosen for projects with high pressure, while for projects without pressure or with low pressure, low-cost straight seam pipes are chosen when allowed.

Hot rolled pipes are rolled relative to cold rolling, which is carried out below the recrystallization temperature, while hot rolling is carried out above the recrystallization temperature.
