BACKSeamless steel pipe
20cr cold drawn seamless pipe
Description:20cr cold drawn seamless pipe is used for mechanical structure, hydraulic equipment of high dimensional accuracy and good surface finish of precision cold drawn seamless pipe. The selection of precision seamless tube manufacturing mechanical structure or hydraulic equipment, can greatly save machining hours, improve the utilization rate of materials, and help to improve product quality.
parameters
According to the different requirements of our goods units, imported seamless pipe specifications as many as 100 kinds, common specifications are 15922mm, 1595mm, 15918mm. 114.38mm, 114.310mm, 114.313mm. The length ranges from 5 to 8m or 4 to 7m. Mainly hot rolled carbon structure, and ST65. The smallest diameter of the import specification is 305mm and the largest is 47813mm.
introduction
The difference between 20cr cold-drawn seamless pipe and general ordinary seamless steel pipe:
1, general ordinary seamless steel pipe is mainly characterized by no welding joints, can withstand greater pressure. The product can be very rough cast or cold - drawn.
2. Cold-drawn precision steel pipe is a product that has appeared in recent years. It mainly has strict tolerance and roughness of inner hole and outer wall size.
Characteristics of cold-drawn (rolled) precision steel pipe:
1. Smaller outside diameter.
2. High precision can be done in small batches
3. Cold drawing (rolling) finished products have high precision and good surface quality.
4. The cross area of the steel pipe is more complex.
5. The steel pipe has superior performance and the metal is relatively dense.
