Product Overview

High precision size seamless steel tube (DIN2391 ST35/ST45/ST52 cold drawn) for mechanical structures, hydraulic equipment and automotive parts. Precision pipe is carbon, alloy or stainless steel pipe with high precision sizes, made through hot rolling or cold drawn (cold rolling). Advantages: no oxide coating inside and outside; bears high pressure with no leaking; strict less tolerance; smooth surface.
