DN200 Pressure Resistant Double Ball Rubber Joint With Booster Ring

Rubber expansion joints consist of inner and outer rubber,nylon cord fabric , which are vulcanized and then combined with metal flanges or loose sleeves of parallel joints. This product can reduce vibration and noise, and compensate thermal expansion and contraction caused by temperature change. It is widely used in various pipeline systems.

According to different material, acid resistance rubber joint, oil resistant rubber joint, thermostatic rubber joint, low temperature resistant rubber joint, wear resistance rubber joint can be made to suitable for various kinds of medium, and environment.

Flange Rubber Expansion Joint application

Flange rubber expansion joint are widely used in various pipeline systems, such as the connection of joint expansion with pumps and valves, fire-fighting equipment and pipelines with large vibration. Pipes with frequent changes of heat and cold.

Flange rubber expansion joint is mainly used for remote water and sewage lifting and transportation, water supply and cooling circulating water of thermal power plant, pipeline transportation of metallurgical industry, condensate water, chemical industry, cooling and dilution of petrochemical industry, and flexible connection between long and short distance pipelines in other industries.

FAQ

Q: The pipe is flange connected, so does the rubber joint need a gasket when installing it?
A: No gasket is needed, because the sealing surface of the rubber joint itself is protruding, as long as it is consistent with the flange connection on the pipe.

Q: How to choose the rubber material?
A: The rubber material depends on the circulating medium. If the medium is ordinary domestic water, natural rubber is used; if the medium is corrosive, weak acid and weak alkali, EPDM rubber can be used.

Q: What are the flange materials?
A: Ductile iron, galvanized carbon steel, stainless steel, etc.

Q: What are the flange standards? Do you support customization?
A: Flange standards include EN1092, ANSI 150LB, DIN PN16, BS4504, HG/T 20592,AWWA C207 etc.
Of course, customization is supported, but you need to provide accurate flange data for confirmation by factory technicians.
