Product Description

      The maximum diameter of seamless steel pipe is 650mm and the minimum diameter is 0.3mm.

A steel pipe made of a whole piece of metal with no seams on the surface is called a seamless steel pipe.

According to the production method, seamless pipes are divided into hot-rolled pipes, cold-rolled pipes, cold-drawn pipes, extruded pipes, top pipes, etc.

According to the cross-sectional shape, seamless steel pipes are divided into round and special-shaped pipes. Special-shaped pipes have square, oval, triangle, hexagon, melon seed, star, winged pipes and many other complex shapes.
