Technology: High quality carbon steel, fine drawing, non-destructive testing, pipe wall and through a dedicated high-pressure washing equipment scrub, anti-rust oil for rust on steel processing, at both ends sealed for dust.

Main Features: Inner and outer walls of tube have high accuracy, excellent brightness, and high cleanness inside tube. The steel tube is able to stand high pressure. No deformation after cold bending, no crack after flaring and flattening. The complicated geometrical forming and machining can be realized.
