Steel Pipe

Product Description

As an important part of steel products, steel pipes are divided into two categories: seamless steel pipes  and welded steel pipes due to their different manufacturing processes and shapes of the tube blanks used.

Seamless steel pipe

Because of their different manufacturing processes, they are divided into two types: hot-rolled (extruded) seamless steel pipes and cold-rolled seamless steel pipes.

Welded steel pipe

The blanks used in welded steel pipes are steel plates or strips. Due to their different welding processes, they are divided into furnace welded pipes, electric welded (resistance welded) pipes and automatic arc welded pipes. Because of their different welding forms, they are divided into two types: straight seam welded pipes and spiral welded pipes. Because of their end shapes, they are divided into round welded pipes and special-shaped (square, flat, etc.) welded pipes.
