Nature of use of flange rubber joints
Rubber joint is a hollow rubber product used as a flexible connection between metal pipes. It is composed of inner and outer rubber layers, cord fabric layer and steel wire ring, which are formed into a tubular rubber part by vulcanization. It can not only reduce vibration and noise, but also compensate for the thermal expansion and contraction caused by temperature changes, and is widely used in various pipeline systems.
Role of flange rubber joint:
Rubber joint is a hollow rubber product used for flexible connection between metal pipes. It is composed of inner and outer rubber layers, cord fabric layer and steel wire ring, and is formed by vulcanization. It can not only reduce vibration and noise, but also compensate for thermal expansion and contraction caused by temperature changes, and is widely used in various pipeline systems. And rubber joints are composed of rubber spheres and flanges, but we all know that the flanges of rubber joints will rust after a period of use.
Types of flanges of rubber joints:
The flanges of rubber joints are divided into three kinds of carbon steel flanges, forged flanges and stainless steel flanges. The good quality is the stainless steel flange, which is widely used in the anti-corrosion pipeline with its unique advantages and does not need to do any treatment, and his service life is long. Stainless steel flange is not easy to rust because of its special material. But carbon steel flanges and forged flanges they contain iron inside the composition, so it is easy to rust, and his service life in the process of use will also be reduced. This time we will take protective measures to prevent rust, we often use the spraying and hot-dip galvanizing these two methods to prevent the flange rust.
The name of the rubber joint flange we are called according to his material, for example, the material of cast steel flange we call cast steel flange, and cast steel flange is what we call forged flange, the surface of this flange is not porous suitable manufacturing process is hot dip galvanizing, because his surface is flat, using hot dip galvanizing treatment of his long service life. And carbon steel material flange is carbon steel flange, carbon steel flange is produced in the way of casting, such a production method will make the flange on the phenomenon of porosity, so if the use of galvanized way to prevent rust will expose the shortcomings of carbon steel flange. So we generally use the form of plastic spraying to anti-corrosion, so after the coverage of plastic powder, will be good to make up for the shortcomings of the carbon steel flange, and from the appearance of the basic do not see the phenomenon of porosity.
