Rubber joint, flexible rubber joint, flexible rubber connection, rubber expansion joint

Description :

Also known as flexible rubber joint, rubber soft joint, shock absorber throat, rubber expansion joint, flexible joint; It is a flexible pipe connector made of vulcanized rubber composite reinforcement layer and metal flange/threaded joint, manufactured according to GB/T 26121 and GB/T 12465, used for absorbing vibration, compensating displacement, reducing noise, and adapting installation deviations.

 2、 Core structure

1.  Internal adhesive layer: Contact medium, EPDM resistant to water/steam, NBR resistant to oil, FKM resistant to strong corrosion;

2.  Enhancement layer: multi-layer scraped nylon/polyester curtain fabric+steel wire ring, pressure resistant and deformation resistant;

3.  External adhesive layer: weather resistant, ozone resistant, anti-aging;

4.  Connectors: Carbon steel/stainless steel flanges (loose/fixed), threaded joints;

5.  Optional limit pull rod: anti excessive stretching/pulling off (mandatory for high pressure/suspension).

3、 Core functions

-Multi directional displacement compensation: axial extension, lateral offset, angular deflection;

-Shock absorption and noise reduction: attenuate water pump/fan vibration by 60% -80%, and reduce noise by 15-30dB;

-Adapt to installation/settlement deviations, protect the pump valve and pipeline interface;

-Reliable sealing and prevention of medium leakage.

4、 Common Categories

1.  Structure: Single sphere (conventional), double sphere (large displacement), reducing, curved sphere;

2.  Connection: flange type (most commonly used), threaded type (small pipe diameter), clamp type;

3.  Working conditions: ordinary type, high pressure resistance, high temperature resistance, oil resistance, corrosion resistance, wear resistance (conveying slurry).

5、 Typical applications

Municipal water supply and drainage, heating/air conditioning, chemical industry, petroleum, electricity, metallurgy, shipbuilding; Especially at the inlet and outlet of water pumps, pipe penetrations through walls/wells, long-distance pipelines, and equipment connections with high vibration
