A stainless flange solution provider is a circular ring made of a material that can undergo plastic deformation and has a specific strength. Most stainless flange solution providers are cut from non-metallic plates or manufactured by factories in standard sizes. The materials are asbestos rubber plates, asbestos plates, polyethylene plates, etc. Some are made by wrapping non-metallic materials such as asbestos around thin metal plates (white iron sheets, stainless steel) to form a metal-covered stainless flange solution provider.
There is also an alternative type of stainless flange solution provided by using a thin steel strip and a asbestos strip wound together in a spiral form. The ordinary rubber stainless flange solution provider is suitable for places with a temperature lower than 120℃; the asbestos rubber stainless flange solution provider is suitable for places where the temperature of water vapor is lower than 450℃, the temperature of oil is lower than 350℃, and the pressure is lower than 5MPa. For common corrosive media, the most commonly used is acid-resistant asbestos sheet. In high-pressure equipment and pipelines, lens-shaped or other-shaped metal stainless flange solutions provider made of copper, aluminum, No. 10 steel, and stainless steel are adopted. The contact width between the high-pressure stainless flange solution provider and the sealing surface is narrow (line contact), and the processing brightness of the sealing surface and the stainless flange solution provider is relatively high.
The sealing principle of stainless flange solutions provider:
The two sealing surfaces of the bolt press against the flange and form a seal, but this also leads to the destruction of the seal. To maintain the seal, a large bolt force is required. Therefore, the bolt must be made larger. And a larger bolt requires a larger nut, which means that a larger diameter bolt is needed to create conditions for tightening the nut. However, the larger the bolt's diameter, the more the flange will become bent. The only solution is to increase the wall thickness of the flange section. The entire installation will require larger dimensions and weight, which becomes a particular problem in the offshore environment, as weight has always been the main concern in such conditions. Moreover, fundamentally, stainless flange solutions provider is an ineffective seal. It requires 50% of the bolt load to be used to press the stainless flange solutions provider, while only 50% is used to maintain the pressure.
