Cold Rolled Seamless Steel Tube and Pipe
Overview
Cold-drawn seamless pipes are usually made of carbon steel and are produced by piercing the hot billet and then rolling it to reduce its diameter and elongate it. The material then passes through a die and a mandrel plug to achieve precise dimensions and specifications, mainly for use in automobiles, trucks, aircraft, and machinery.
Key Features
High dimensional accuracy
High surface finish
Great advantages in the precision machining industry
