High-precision cold-drawn precision steel pipe is a new type of steel pipe, whose main feature is high precision. Usually two-roller mill and three-roller mill production of two production processes, three-roller mill production of cold rolled seamless steel tube precision is higher, can be controlled within a few silk, but the price is relatively high.The promotion of high-precision cold-drawn precision steel tubes to save steel, improve processing efficiency, save energy The so-called high-precision cold-drawn seamless steel tube refers to the internal and external dimensional accuracy (tolerance range) is strict, internal and external surface finish, roundness, straightness, can greatly save machining hours, improve material utilization, while helping to improve product quality.

The main cold processing methods of steel pipe are cold drawing and cold rolling method. In recent years, with the development of science and technology, and the development of a cold spinning method, with this method can produce large diameter, high-precision cold-rolled tubes and cold-rolled tubes with variable cross-section. Cold processing of steel pipe raw materials can be hot-rolled seamless steel pipe can also be welded pipe. The common feature of the cold processing method of steel pipe is the high dimensional accuracy, good surface roughness, can produce very thin (up to 0.05 ~ 0.01mm) thin-walled tubes and very fine (diameter up to 0.3 ~ 0.1 mm) capillary tubes.Seamless steel pipes are pipes with hollow cross-section, which are used in large quantities as pipelines for transporting fluids, such as pipelines for transporting oil, natural gas, gas, water and certain solid materials. Compared with solid steel such as round steel, steel pipe is lighter in weight when the bending and torsional strength is the same, and is an economic cross-sectional steel, which is widely used in pipeline engineering.

The promotion and application of high-precision cold-drawn precision steel tubes to save steel, improve processing efficiency, save energy The so-called high-precision cold-drawn seamless steel tubes refers to the internal and external dimensional accuracy (tolerance range) is strict, internal and external surface finish, roundness, straightness is good, can greatly save mechanical processing hours, improve material utilization, while helping to improve product quality.

Production ：ProcessRound tube blank→heating→piercing→three-roller skew rolling, continuous rolling or extrusion→tube removal→sizing (or reducing)→cooling→straightening→hydrostatic test (or flaw detection)→marking→storage seamless steel pipe It is made of steel ingots or solid tube blanks through perforation to make capillary tubes, and then hot-rolled, cold-rolled or cold-drawn.
