Description: Rubber expansion joints, also called rubber compensators, are flexible connectors made of natural and/or synthetic elastomers and fabrics. If necessary, internal metal reinforcement materials can be used. These materials are designed to relieve thermal movement and piping system stress caused by mechanical vibration. Rubber expansion joint material: EPDM, NBR, NR Type: Single ball rubber expansion joint Double ball rubber expansion joint Flange connection rubber expansion joint Threaded rubber expansion joint Feature: 1. Good displacement compensation ability, capable of axial, lateral and angular displacement. 2. Low noise, good vibration damping and corrosion resistance. 3. High pressure resistance, good elasticity, good displacement effect and simple installation. Application: Rubber expansion joints can be widely used in heating and cooling devices, water pipes, desalination plants, compressors, blowers and fans, cement industry, chemical industry, glass industry, wood processing industry and other pipeline Systems
