Introduction

Rubber expansion joint is also called: flexible rubber expansion coupling, rubber soft connection, and soft rubber joint, rubber compensator, rubber shock hose, rubber shock reducer, is one kind of high elasticity, high air tightness, medium resistance and weather ability pipe fittings.

Rubber expansion joint consists of outer rubber, inner rubber, framework layer, and reinforcing bar and flange. Relying on rubber's special performances as long range elasticity, air impermeability, medium, climate and radiation resistance, rubber expansion couplings can reduce the vibration and noise of pipeline, and can be caused by the temperature change of heat bilges cold shrink compensation effect.

Classification:
1) According to appearance: concentric with diameter rubber expansion joint, concentric reducer rubber expansion joint, eccentric reducer rubber expansion joint.
2) According to the structure: single ball rubber expansion joints, double sphere rubber joints, spheres rubber joints, elbow sphere rubber joints.

3) According to the link the form: flange rubber joints, union rubber joints.

Characteristic Feature:

(1)Small volume, light in weight, very good flexibility, Convenience installation and maintenance.

(2)Transverse displacement, axial displacement, angular displacement

(3)Reduce noise, shock absorption

Range of application:

Due to favorable integrated performance, they can be widely used in chemical industry, Construction, water supply, drainage, oil industry, light and heavy industry, refrigeration station, water heating system, fire fighting system, electric power system, etc.
