Precision Seamless Steel Tube
Product Description:
The raw materials of the steel pipe are fine drawing, no oxidation
bright heat treatment (NBK state), non-destructive testing, the
inner hole of the steel pipe is high-pressure washing, pickling,
the inner and outer walls of the steel pipe are treated with
anti-rust oil, and the ends of the cover is used as dustproof
treatment.
