Round Steel Pipe & Tube

Round steel pipe & tube are steels that are open at both ends and have a hollow concentric section with a length that is relatively large compared to the circumference. It can be used in pipelines, thermal equipment, machinery industry, petroleum geological drilling, containers, chemical industry and special applications.

Classification of round steel pipe:
According to production methods can be divided into seamless round steel pipe and welded round steel pipe.
