What is the difference between rubber expansion joint and rubber joint?
A rubber joint is a hollow rubber product used for flexible connections between metal pipes. The flexible joint is also called soft rubber pipe joints, rubber joints, soft rubber joints, flexible joints, high-pressure rubber joints, rubber shock absorber etc..
The expansion joint is also called expansion device, expansion joint and compensator. It is divided into several types, such as ripple compensator, sleeve compensator, rotary compensator and square natural compensator, and also has intubation type expansion joint. Among them, the corrugated compensator is more commonly used, mainly to ensure the safe operation of the pipeline, and has the following functions: 1.. Compensating the axial, transverse and angular thermal deformation of the absorption pipeline. 2. vibration absorption equipment to reduce the impact of equipment vibration on the pipeline. The deformation of the pipeline 3., absorption of seismic subsidence.
It is divided into 3 kinds: flange type, fixed flange type and thread type by connection. The structure can be divided into single sphere, double sphere and curved sphere. A tubular rubber component is composed of inner and outer layers of rubber, cord and steel ring, which is vulcanized and molded and then combined with a metal flange or a parallel joint. This product can reduce vibration and noise, and can be compensated by thermal expansion and cold contraction due to temperature changes. It is widely used in various piping systems. Rubber joint is a kind of pipe joint with high elasticity, high air tightness, medium resistance and weather resistance. The product uses rubber elasticity, high air tightness, medium resistance, weather resistance and radiation resistance etc., using polyester cord fabric skew high strength, strong stability and the hot and cold composite, after high pressure, mold temperature and curing. As the rubber joint has good comprehensive performance, it mainly acts as shock absorption, noise elimination and noise reduction. Therefore, it is widely used in chemical, construction, water supply, drainage, petroleum, light and heavy industries, freezing, sanitation, plumbing, fire fighting, power and other infrastructure projects.
