summarize

The common features of the steel pipe cold working method are high dimensional accuracy and good surface roughness. The production process of a general seamless steel tube can be divided into two types: cold rolling and hot rolling. In appearance, cold-rolled seamless steel pipes are shorter than hot-rolled seamless steel tubes. The surface is not too rough, and the calibre does not have too many burrs.

The main advantage of rolled steel pipes is the large section reduction rate, especially the strong wall reduction ability. At present, periodic cold rolled seamless steel tube machines are mostly used in the production of cold-rolled pipes. The reciprocating movement of the frame drives the rolling of the steel pipe, and the variable cross-section profile is used to compress the rolled piece to achieve the purpose of diameter and wall reduction.

Advantages

Fast forming speed, high output, and does not damage the coating. It can be made into a variety of cross-sectional forms to adapt to the needs of use conditions; cold rolling can cause large plastic deformation of steel, thereby improving the yield of the steel. The manufacturing process of cold rolled seamless steel pipe is more delicate and complex than that of ordinary steel pipe, which improves the precision of the steel pipe. The equipment and process used in the manufacturing of cold rolled seamless steel pipe is also more complex, which can ensure the precision and quality of the steel pipe. Therefore, cold rolled seamless steel pipe can meet the needs of some high-precision processing and application occasions.

Application

1. Machinery manufacturing field

Used to manufacture tyres, engines, shock absorbers, transmissions, drive shafts, crankshafts, balance shafts and other mechanical parts to meet the needs of different fields.

2. Automobile manufacturing field

It is suitable for manufacturing lightweight bodies, chassis, engines and other parts. It has the characteristics of high strength, good durability and corrosion resistance. It can improve the quality and reliability of automobile parts and make the vehicle safer, more stable and environmentally friendly.

3. Aerospace field

Due to its excellent high-temperature strength and corrosion resistance, it can meet the requirements of aircraft engines, gas turbines, high-temperature and high-pressure vessels and other components, and is used to improve the safety, reliability and performance of aerospace equipment.

4. Petrochemical field

Cold-rolled seamless steel pipes are widely used in pipeline transportation systems, which can improve the safety and reliability of petrochemical transportation systems.
