6m Length Cold Drawn Steel Tube , Precision Steel Pipe For
Automotive SAE 1026
Precision steel pipe is a kind of high precision steel pipe
material after cold drawing or hot rolling treatment. It is mainly
used for the production of pneumatic or hydraulic components, such
as cylinders or cylinders, because of the advantages of
high-pressure non-leaking, high-precision, high-grade finish,
cold-formed deformation, flaring, flattening and no cracks.
