Flanged rubber expansion joint has a small size, good elasticity and other advantages, which creates it installed in the pipeline can be easily installed and removed.
In the installation process, the flange can not be rotated at will, by using the bolt set to fix greatly improve the sealing and pressure resistance of the product.
When the bolts are installed, the flange and the edge of the sphere are installed inside together, which greatly increases the pressure resistance strength, generally up to 2.5Map or 4.0Map pressure. The sphere is configured with a booster ring outside, and the flange is configured with a limit device at both ends to prevent the pipeline pressure from rising to produce super limit radial displacement, thus playing a role in protecting the equipment.
The application range is wider because the rubber joint has good comprehensive performance, so it is widely used in chemical industry, construction, water supply, drainage, petroleum, light and heavy industry, refrigeration, sanitation, plumbing, fire-fighting, electric power and other basic projects.
