  16Mn seamless steel pipe is now a relatively important type of steel. It is precisely because of its great effect and used in key areas, so the demand for it is still relatively large. At the time of purchase, there is still a concern about the service life of 16Mn seamless steel pipes, so how can we extend the service life of 16Mn seamless steel pipes?   The common method is:   The first method is to remove rust from steel pipes. When removing rust from steel pipes, steel wire brushes are mainly used to polish its surface. This method can effectively remove loose or raised rust on the surface of steel pipes.   The second method is to clean the surface of the steel pipe. When cleaning the steel pipe, the surface should be cleaned with solvent or emulsion to achieve the effect of degreasing and dust removal. This method is only suitable for removing grease on the surface of the steel pipe. And dust can not remove rust and oxide scale, so this method can only be use...

  From smelting to rolling, pipe processing and heat treatment of seamless steel pipes , the chemical composition, metallography, mechanics, and metal physical properties must meet the requirements for use.   The performance of seamless steel pipes can be divided into two categories:   Performance: including mechanical properties, physical properties, chemical properties Process performance: including casting performance, pressure processing performance, welding performance, cutting performance, heat treatment performance. Simply put, the mechanical properties of seamless steel pipes are the ability of seamless steel pipes to resist external forces. The external force acting on the metal material. According to the nature of the load, it can be divided into static load, impact load and alternating load. Commonly used mechanical performance indicators are: strength, plasticity, hardness, impact toughness, fatigue strength, etc.   The strength of seamless steel pipe ref...

      How to distinguish the authenticity of 16mn seamless steel pipe? 1. Fake and shoddy 16mn seamless steel pipes are easy to fold. Folding is a variety of fold lines formed on the surface of the 16mn seamless steel pipe. This defect often runs through the longitudinal direction of the entire product. The reason for the folding is that the counterfeit manufacturers are pursuing high efficiency, the amount of reduction is too large, and the ears are generated. The folding occurs during the next rolling. The folded product will crack after bending, and the strength of the 16mn seamless steel pipe will be greatly reduced.   2. Fake and inferior 16mn seamless steel pipes often have pitting on the surface. The pitted surface is caused by the serious wear of the rolling groove, which causes the irregular uneven surface of the 16mn seamless steel pipe. As the manufacturers of counterfeit and inferior 16mn seamless steel pipes are pursuing profits, the groove rolling of...

Seamless steel pipe occupies an important position in the national social economy. Perhaps our friends do not understand it very well, but it has been widely used in petroleum and chemical management and other aspects, bringing a new dimension to people ’ s lives. Great convenience. Seamless steel pipes are also divided into many categories in my country. Among them, Chinese stainless steel pipes are generally used by students in an ideal living environment. 　　 It is not difficult to find in life that the garden fences and staircase handrails that people see are all made of stainless steel pipes. The stainless steel pipe is small in size, which is convenient for people to install. It also has good corrosion resistance, thereby reducing a lot of unnecessary expenses, especially when it is used as a garden fence, it will not be corroded in a humid environment. Stainless steel pipes also have strong toughness, but this toughness is directly related to the size of the hole diameter. As a s...
