NBR Rubber Metal Flexible Expansion Joints Can be Customized
Rubber metal flexible expansion joints is chemically fused to pre-treated metal surfaces (sandblasted or primed) to ensure adhesion integrity. Advanced methods like injection molding or compression bonding create homogeneous interfaces resistant to delamination. Optional features include PTFE-lined rubber layers for chemical resistance or spiral-wound metal wire cores for enhanced collapse resistance under vacuum conditions.

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 flexible expansion joints production Flow
Do you know how is a Rubber metal flexible expansion joints made?Let's see with JINGNING.
It is very important to select the appropriate expansion joint flange 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 flexible expansion joints for any application.
Rubber Metal Flexible Expansion Joints Advantage
1. Rubber metal flexible expansion joints is galvanized for 15 minutes, resistant to high pressure, high temperature, oil, wear, corrosion, acid and alkali.
2. Rubber metal flexible expansion joints 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 rubber metal flexible expansion joints is 47%, which can be used continuously for 15 years without aging.
Rubber Metal Flexible Expansion Joints Application
Rubber metal flexible expansion joints 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 ℃.
