PTFE rubber expansion joint is a hollow rubber product used for flexible connection between metal pipes. It consists of inner and outer layer of rubber, cord fabric layer and steel wire ring, which is formed by vulcanization and then loosely combined with metal flange or parallel joint. This product can reduce vibration and noise, and can compensate for the thermal expansion and contraction caused by temperature changes, and is widely used in various pipeline systems. The product is manufactured by new technology of air-blown mold, which is composed of sphere with inner rubber layer, reinforcement layer, middle rubber layer, outer rubber layer and loose-fitting forged low carbon steel flange, with the characteristics of high pressure resistance, good elasticity, large displacement, good vibration and noise reduction, and easy installation. In addition, the product has good acid and alkali resistance and stable chemical state, which can greatly reduce the erosion effect of corrosive media on rubber joints. It can be widely used in pipeline systems such as water supply and drainage, HVAC, fire fighting, compressor, paper making, pharmaceutical, ship, pump and fan.
Features of PTFE rubber expansion joint: high internal density, can withstand high pressure, good elastic deformation effect.
Advantages of PTFE rubber expansion joint: vibration damping, noise reduction, lightness.
Application of PTFE rubber expansion joint: connection with pump and valve, especially suitable for pipeline with high vibration and frequent hot and cold changes. The rubber joint is composed of fabric-reinforced rubber parts and loose metal flange connection, which is used for pipeline vibration isolation and noise reduction, compensation displacement joint. It is a kind of pipeline joint with high elasticity, high airtightness, medium resistance and weather resistance.
