Rubber Flexible Expansion Joints are rubber joints specifically designed to withstand high temperatures, high pressures, and corrosive media. They mainly consist of a rubber body, metal flanges, and fasteners. The rubber body is made of high-strength, corrosion-resistant, and aging-resistant special synthetic rubber, capable of withstanding extreme temperatures and chemical erosion. Its unique corrugated structure gives it excellent flexibility, expansion, deflection, and vibration resistance, effectively absorbing and compensating for displacements caused by thermal expansion and contraction, mechanical vibration, and ground settlement, significantly reducing the stress on the pipeline system and preventing damage to pipelines and equipment.
Components of a Rubber Flexible Expansion Joint:
1. Flanges: Both ends of the rubber expansion joint are connected to the pipeline via flanges, typically bolted. These flanges not only connect the pipeline but also provide a fixing function, ensuring safe pipeline operation.
2. Rubber Ball: The rubber ball is the core component of the rubber expansion joint, its main function being to provide a flexible connection. Generally, rubber balls are made of natural rubber or silicone rubber, possessing excellent elasticity and corrosion resistance, suitable for pipelines carrying various media.
3. Inner Steel Wire Ring: The inner steel wire ring is fixed inside the rubber ball, enhancing its load-bearing capacity and stability, ensuring the rubber ball does not deform or even break.
4. Central Rib: The central rib connects the two flanges and the rubber ball, maintaining the stability of the rubber expansion joint and enabling it to provide good buffering and compensation within the pipeline.
5. Outer Steel Wire Ring: The outer steel wire ring restores the shape of the rubber expansion joint, ensuring its normal operation.
