Cold Drawn 20# carbon small diameter precision seamless steel tube
Precision seamless steel pipe is a kind of high-precision steel pipe
processed by cold rolling or cold drawing; full name: cold-rolled precision
seamless steel pipe Since the inner and outer walls of precision seamless
steel pipes have no oxide layer, bear high pressure without leakage, high
precision, high smoothness, cold bending without deformation, flaring,
flattening without cracks, etc., they are mainly used to produce pneumatic
or hydraulic components, such as Cylinders or oil cylinders are made of
seamless pipes
