Cold Drawn Seamless Steel Pipe
Cold drawn seamless steel pipes include low- and medium-pressure steel pipe, high-pressure boiler steel pipe, alloy steel pipe. Meanwhile, it can be divided into carbon steel thin-wall steel tube, alloy steel thin-wall steel tube, stainless steel thin-wall steel tube, and special-shaped steel tube.
Cold rolled steel pipe has higher dimensional accuracy than hot rolled steel pipe. The outside diameter of cold drawn seamless steel pipe can be up to 6mm, and the wall thickness can be up to 0.25mm. The outside diameter of thin-wall pipe can be up to 5mm, and the wall thickness can be up to 0.25mm.
Manufacturing Process of Cold Drawn Seamless Steel PipeRound pipe billet→ heating→ boring→ driving pipe head→ annealing→ acid cleaning→ oiling(copper plating)→ multiply cold-drawing(cold-rolling)→ semi-finished pipe→ heat treatment→ straightening→ hydraulic testing for fault detection→ marking→ entering warehouse
