Insulation joint voltage and performance and anti-corrosion treatment

Insulation joint voltage and performance and anti-corrosion treatment

This does not happen in soil or water-containing media. Generally, erosion occurs locally and is uneven, and the current balance in a small area along the surface is uneven. Without continuous corrosion of the battery, this is basically the case with natural corrosion with uniform material loss. On the other hand, the picture shows a continuous corrosion cell separated by several kilometers. This usually happens in the soil of local defense. The natural corrosion potential depends on the location, and there is no single electrostatic potential.

The stamping process has more advantages than other parts

Compared with castings and forgings, stamping parts are thin, even, light and strong. Stamping can produce workpieces with ribs, undulations or flanges that are difficult to manufacture by other methods to improve their rigidity. Due to the use of precision molds, the precision of the workpiece can reach the micron level, and the repeatability is high, the specifications are consistent, and holes, bosses, etc. can be punched out. Cold stamping parts are generally no longer processed by cutting, or only a small amount of cutting processing is required. The precision and surface condition of hot stamping parts are lower than cold stamping parts, but still better than castings and forgings, and the cutting amount is less.

What is the sealing effect of carbon steel flanges

For the rigidity requirements of carbon steel flanges, when flange design was originally carried out, only the strength calculation was carried out, and the rigidity calculation was rarely carried out. However, more and more production practices have proved that the flange stiffness will also affect the sealing performance of the flange. , Flanges with insufficient rigidity will produce excessive warpage and deformation, which will cause uneven stress on the gasket and lead to leakage. The carbon steel flange connection is a detachable connection. According to the connected parts, it can be divided into container flange and tube carbon steel flange. In high-pressure equipment and pipelines, metal gaskets of lens type or other shapes made of copper, aluminum, 10# steel, and stainless steel are used. The contact width between the high-pressure gasket and the sealing surface is very narrow (line contact), and the processed carbon steel flange of the sealing surface and the gasket has a higher finish.
