- Expansion coefficient of precision tube 2022/06/15
- The inspection method can be smeared with soapy water at the joints of the annealing furnace to see if gas escapes. The places where the gas is easy to escape are the places where the annealing furnace enters the pipe and t...
- What is hot rolled pipe 2022/03/10
- The hot-rolled precision steel pipe is made of continuous casting round tube billet slab or pre-rolled slab as raw material, heated in a walking furnace, descaled by high-pressure water, and then enters the rough rolling mill. ...
- Introduction of square and rectangular tube 2021/11/12
- Square and rectangular tube, also known as square and rectangular cold-formed hollow steel, referred to as square tube and rectangular tube, codenamed F and J respectively. 1. The allowable deviation of the wall t...
- Hardness and Deformation of Precision Steel Tubes 2021/07/15
- Take two samples, one is used to study the effect of different deformation degrees on hardness, and the other is used to study the effect of different temperatures on properties. Cold deformation strengthening is ...
- Precision Steel Tubes Improve Dimensional Accuracy 2020/08/20
- The reason why the precision steel pipe has this name is that the precision steel pipe is more accurate in size, the inner and outer surfaces of the steel pipe are also smoother, and the toughness is better. The steel pipe ...
- Analysis of the technological process advantages of precision steel pipes 2020/03/06
- Compared with ordinary pipe materials, the manufacturing process of precision steel pipes has been developed and improved to a certain extent. After the materials enter the production line, ultrasonic waves will be used for...
