Threaded rubber expansion joint union type is also known as: flexible rubber joints, rubber soft connection, soft joint, flexible rubber joints, rubber expansion joints, suspension throat, shock absorber, is a kind of pipe connecting piece with advantages of high elasticity, high air tightness, medium resistance and weather resistance.Protecting piping and equipment system from stress or motion.
Screw thread rubber joint can be widely used in the pipe system of water supply, drainage, circulating water, HVAC, fire protection, paper making, pharmacy, petroleum chemical industry, ship piping system, water pump, compressor and fan etc. The normal type is used to transport air ranges from - 20 °C to 115 °C, compressed air, water, sea water, oil, acid and alkali etc. The special type is used to transport the media above ranges from - 30 °C to 250 °C above, oil or strong alkali, strong acid and solid material.
We introduce advanced technology from abroad, and combine it with Chinese production experience. In the manufacturing operation, the inner side endures high pressure; nylon cord fabrics and the inner rubber are better combined and can work under higher pressure than normal flexible rubber joint. Its characteristics are that the inner adhesive layer united perfectly, bright, clean and seamless; the tag adopts the vulcanization process, perfectly matches the product.

Threaded union rubber expansion joint Advantage:
Rubber expansion joints are generally composed of smooth wave shape compensation element with rubber flange at both ends and metal flange. A loose sleeve structure is often used for metal flange.
The surface of the wave shape compensating element is rubber, and the inner layer is made from multilayer of strong fiber or steel band (wire). The layers of fiber or steel band (wire) has been extended to the ends of the rubber flange, the flange has a hard steel wire skeleton. The rubber expansion joint has a larger displacement compensation ability, which can compensate the axial, lateral and angular displacement, which can reduce the noise, absorb the vibration and has anti corrosion ability. Rubber expansion joints have excellent high pressure resistance, good elasticity, large displacement compensation, nice vibration absorption and noise reduction capability, convenient installation, widely used in water supply and drainage, HVAC, fire control, compressor, paper, pharmaceutical, ship, water pump, fan and other piping systems.
