20# Thick Wall Precision SeamlessTube is a kind of steel pipe with small size tolerance.  After cold drawn or hot rolling process ,the high precision steel tube is without oxidation layer in the surface. Precision steel tube can be under high pressure without leakage, high precision, high finish, cold bending deformation, flaring, flattening without cracks etc, it is mainly used to produce pneumatic or hydraulic components products, such as a cylinder or cylinder, can be a seamless steel pipe, welded pipe

Precision steel pipe is widely used in automobiles, motorcycles, electric cars, petrochemical, electric power, ships, aerospace, bearing, pneumatic components, such as low pressure boiler seamless steel tubes in the category, also can be applied to steel sleeve, bearings, hydraulic, mechanical processing and other fields.
