The application of detachable high hardness force transfer joint, these three advantages, you need t
In case of detachable high hardness force transfer joint structural support, it is necessary to do the insulation treatment of the pipeline to prevent the corrosion situation of potential difference, and the exterior should be wrapped with insulation cotton for anti-corrosion treatment. Steel resistant to weakly corrosive media such as air, steam, water and chemically leaching media such as acids, alkalis and salts, also known as stainless acid-resistant steel. In practical application, we often refer to the steel resistant to weak corrosive media corrosion as detachable high hardness force transfer joint, and the steel resistant to chemical media corrosion as acid resistant steel.
Because of the difference in chemical composition between the two, the former is not necessarily resistant to corrosion by chemical media, while the latter is usually stainless. The corrosion resistance of detachable high hardness force transfer joints depends mainly on the alloying elements contained in the steel. Chromium is the basic element that makes detachable high hardness force transfer joints corrosion resistant.
Besides chromium, other commonly used alloying elements are nickel, molybdenum, titanium, niobium, copper, nitrogen, etc. to meet the requirements of various applications for the organization and properties of detachable high hardness force transfer joints. Usually, the strip is unpacked, flattened, rolled and welded to form a round tube, which is then rolled into a square tube and sheared to the required length. Removable high hardness force transfer joint square tubes are mainly divided into two types: seamless and welded, and removable high hardness force transfer joints are made by extruding seamless round tubes.
The mechanism of rust prevention of detachable high hardness force transfer joints is that the alloying elements form a dense oxide film, which blocks the touch of oxygen and prevents continued oxidation. The surface smoothness and flatness of the detachable high hardness force transfer joint square tube can be judged by observation. If the surface of the detachable high hardness force transfer joint square tube is relatively flat.
Removable high hardness force transfer joint products, especially removable high hardness force transfer joint strips, are in most cases processed in factories by using punching machines for stamping products. Usually hardnesses below 1/2 are utilized for stretching and bending, and hardnesses above 1/2 hardening are straight punched. When the chromium content in steel reaches about 1.2%, chromium and oxygen in the corrosive medium act to form a very thin oxide film (self-passivation film) on the surface of the steel, which can prevent further corrosion of the steel substrate.
