General situation of seamless steel pipe

　　seamless steel pipe is manufactured using a process called “extrusion”. During this process a solid steel bar is pierced though the centre using a die, turning the solid round into a round tube. Basically there are two types of seamless steel pipe. Cold Drawn Seamless (CDS) normally made from SAE 1018, having precise tolerances and good surface finish. Hot Finished Seamless (HFS) normally made from SAE 1026, having less critical tolerances and a scaly finish. It is not as strong as CDS. Cold Drawn Seamless (CDS) has some benefits, such as good surface finish, superior machinability, increased dimensional tolerances and high strength to weight ratio. Hot Finish Seamless (HFS) also has some advantages, including cost effective material, good machinability and wide range of sizes.

　　Seamless steel pipes are used in a range of applications in all different industries, including petrochemical, environmental, energy, fluid water, building and more. We can help you with the right products for your unique application.
