Rubber expansion joints are generally composed of smooth waveform compensated parts with rubber flanges at both ends and metal flanges. The metal flange often adopts a loose sleeve structure. The rubber expansion joint is a flexible device, which is made of natural or synthetic elastomer or fluoroplastic. If necessary, the reinforcement materials (steel, nylon or aramid) of the bellows can also be added. The rubber expansion joint is the perfect solution for the pipeline system to absorb movement, vibration or noise, thus greatly extending the service life of pipeline engineering and connecting equipment.
The surface of the waveform compensated parts are rubber, and the inner layer is several layers of strong fiber or steel belt (wire) reinforced interlayer. Strengthened fiber or steel belt (wire) and other reinforced sandwich has been extended to both ends of the rubber flange, the flange has a hard steel wire skeleton. Related to these materials mention-above, TWT Valve manufactuer always provide high quality with lower cost. So choice of supplier is very considerable. In the meantime, we are also worth to recommand for oversea sale of valves.
The Rubber Expansion Joint features
Rubber expansion joint has a large displacement compensation capacity. It also can be axial, lateral and angular displacement compensation, have to reduce noise, reduce vibration and a certain degree of corrosion resistance. In addition, there are more outstanding features. Such as its high pressure resistance, good elasticity, large displacement, good vibration and noise absorption, easy installation and so on.
The Advantages of Rubber Expansion Joint
Rubber expansion joints provide exceptional performance, reliability and longevity, thus improving plant safety and mechanical integrity of equipment. Due to the insertion of specially designed products in rigid piping systems, rubber expansion joints can: 1. Reduce displacement 2. Improve thermal stability 3. Release system strains caused by thermal variations, load stresses, pump pressure fluctuations, and sediment wear 4. Reduce mechanical noise 5. Compensate eccentricity 6.Eliminate electrolysis between different metals
