High-precision cold-drawn tube is a high-precision seamless steel tube，which is produced by cold-rolling, cold-drawing or a combination of cold-rolling and cold-drawing. It has the characteristics of high dimensional accuracy and good surface finish. Let’s introduce the manufacturing process of high-precision cold-drawn tubes:
(1) Pipe material supply, the pipe materials used are hot-rolled finished pipes or semi-finished pipes, extruded pipes and welded pipes.
(2) Pipe material preparation, including inspection, bundling, pickling, cleaning, rinsing, neutralization, drying, lubricating, etc.
(3) Cold rolling or cold drawing;
(4) Finishing of finished products includes heat treatment of finished products, straightening, sampling, cutting head and tail, inspection, hydraulic test, oiling, packaging, storage, etc. Different products have different finishing contents.
High-precision cold-drawn steel pipe is an ideal metal material for producing honed tubes, which are widely used for manufacturing various hydraulic cylinders. The honed tubes made of high-precision cold-drawn steel pipe has high strength (especailly for 4140 honed tubes), rigidity, good wear resistance and good performance, and the inner surface is hard and the outer surface is tough.
High-precision cold-drawn pipes are used in many industries, mainly in hydraulic system piping, automobile manufacturing piping, and military industry, construction machinery, railway locomotives, aerospace, ships, injection molding machines, die-casting machines, machine tools, diesel engines, petrochemicals, power plants, boiler equipment and other industries.
