Rubber joint is also called rubber flexible joint, this product is enhanced by the fabric rubber parts and flat union, slip-on metal flanged or threaded pipe flange, used for pipeline vibration isolation noise reduction, compensation displacement of the joint.It is a kind of high elasticity, high air tightness, medium resistance and weatherability of pipe joint.
According to the shape is divided into: concentric diameter, concentric reducer and eccentric reducer.According to the structure is divided into: single ball, double ball, bend sphere.
According to the connection form can be divided into: flange connection, threaded connections, threaded pipe flange connection.
According to the working pressure points: 0.25 MPa, 0.6 MPa, 1.0 MPa, 1.6 MPa, 2.5 MPa five grades.

Performance characteristics:
1, small volume, light weight, good elasticity, easy installation and maintenance.
2, the installation time can produce transverse, axial, angular displacement, pipe impassability heart, flange unparallel restrictions.
3, the structure of the work can reduce the noise, vibration absorbing ability.

Due to the rubber flexible joint has good comprehensive performance, so it is widely used in chemical industry, building, water supply, water drainage, oil, light and heavy industry, frozen, sanitary, plumbing, fire protection, electric power and other infrastructure.At the top when using the product, water pipe must have a fixed support or fixed bracket, otherwise the product should be installed pulled off prevention device.And fixed support bracket of force must be greater than the axial force, otherwise also should install pulled off device
