RFJH Rubber Metal Expansion Joint Installation Flexible Bellows
Rubber metal expansion joint installation is a composite fitting that integrates rigid metallic components (such as stainless steel or aluminum flanges) with elastomeric rubber sleeves or bellows. This synergy provides vibration damping, misalignment compensation, and pressure containment, bridging rigid piping systems while mitigating mechanical stress. Common configurations include braided hoses with metal end fittings or flexible joints with embedded reinforcement rings for burst resistance.

Note: 1. The special requirements of rubber metal pipe connector can be customized according to the user's drawing. Flange standard is GB / t9115.1-2000. Various flange standards (GB, JB, Hg, CB, ANSI, DIN, BSEN, NF, en, JIS, ISO, etc.) can be selected for production. The rubber ball of rubber metal pipe connector can be used as natural rubber, ethylene propylene diene monomer rubber, chloroprene rubber, butyl rubber, butadiene rubber, fluorine rubber, etc. When the rubber metal pipe connector above DN200 is used for suspended water supply, the pipe must have fixed support or fixed support, otherwise the rubber metal pipe connector shall be installed with anti falling device.
Typical installation
The installation in the piping of the anti-vibration joints near of pumps, compressors, control devices, valves, operating machines, etc., allows to interrupt the propagation of sound waves and to absorb small vibrations.
Rubber Metal Expansion Joint Installation production Flow
Do you know how is a Rubber Metal Expansion Joint Installation made?Let's see with JINGNING.
It is very important to select the appropriate rubber metal expansion joint installation of the pipeline, understand the compatibility of the medium with the selected material, the full temperature, pressure and vacuum range, the required movement and the size between the pipeline flanges. With this information, Jingning application engineers can help determine the ideal rubber metal expansion joint for any application.
Rubber Metal Expansion Joint Installation Advantage
1. The rubber metal expansion joint is galvanized for 15 minutes, resistant to high pressure, high temperature, oil, wear, corrosion, acid and alkali.
2. Expansion joint flange are connected with pumps, valves, fire-fighting equipment, pipes with large vibration and pipes with frequent changes of cold and heat.
3. The natural rubber content of expansion joint flange is 47%, which can be used continuously for 15 years without aging.
Rubber Metal Expansion Joint Installation Application
Rubber metal expansion joint are mainly used for heating, pumping and air conditioning of apartment buildings, hospitals, schools and other facilities. Applicable liquid environment of expansion joint flange: water, seawater, weak acid and weak alkali, etc.; Maximum working pressure of rubber metal pipe connector: 10 bar; Maximum continuous working temperature of rubber metal pipe connector: + 100 ℃.
