Principle and structural features

Because zinc is not easily transformed in dry air, but in a humid environment, a very dense zinc carbonate plastic film can be formed on the surface. This type of plastic film can effectively control the internal structure from being eroded again. Moreover, when various reasons cause the coating to be damaged and expose a substrate that is not particularly large, zinc and steel substrates generate micro-batteries, making the standard part substrate a negative electrode and being protected. It is widely used in the fields of transportation, etc., but what is more needed is a trivalent chromium passivation layer and a zinc-nickel alloy plated closed coating to reduce the harmful and harmful layer of hexavalent chromium passivation treatment.

The main body of the rubber joint is composed of a rubber tube and a flange. Many customers believe that the most important part of the rubber joint is the rubber tube, but the flange on the rubber joint is also very important. The flange on the rubber joint is mainly used as the core equipment for connecting the rubber joint to pipelines and water pumps. Due to the special properties of the rubber joint, it cannot be connected by welding like other equipment. Therefore, the importance of the rubber joint flange is self-evident. So, how should you choose the flange of the rubber joint?

The quality of the rubber joint flange has a great relationship with its material. The better the material, the more durable the rubber joint flange. At present, the main materials of high-quality rubber joint flanges sold on the market are cast steel flanges and forged flanges. These two materials are widely used. The quality of forged flanges is better than that of cast steel flanges. So how are these two flanges produced? The most direct method for cast steel flanges is to use steel plates of a certain thickness, cut them, and then use a round car to round the surface. After the surface is rounded, drill holes according to the specified hole positions to produce cast steel flanges. The forged flange is produced on the basis of the cast steel flange, and its strength and quality are much better than that of the cast steel flange.

Flexible pipe fittings made of rubber as the main material and formed by vulcanization process, used to compensate for thermal displacement of pipelines, absorb vibration and reduce noise.
