Rubber expansion joint is composed of inner rubber layer, multi-layer squeegee nylon cord fabric and outer rubber ring to form a tubular rubber part, which is formed by high temperature and high pressure vulcanization and then loosely combined with metal flange or parallel joint. According to the connection method, it can be divided into loose type and fixed type; according to the structure, it can be divided into single sphere and multi-sphere; according to the working pressure, it can be divided into different levels such as 0.6, 1.0, 1.6, 2.5mpa.
