The difference between rubber expansion joint and rubber joint

1. Expansion joints are also called expansion joints, expansion joints, and compensators. They are divided into several types: corrugated compensator, sleeve compensator, rotary compensator, square natural compensator, etc., as well as intubation type expansion joints. Among them, the corrugated compensator is more commonly used, mainly to ensure the safe operation of the pipeline, and has the following functions: 1. Compensate the axial, lateral and angular thermal deformation of the absorption pipeline. 2. Absorb equipment vibration and reduce the impact of equipment vibration on the pipeline. 3. Absorb the deformation of the pipeline caused by earthquake and ground subsidence.

2. Rubber joints are hollow rubber products used for flexible connection between metal pipes. Soft joints are also called rubber tube soft joints, rubber joints, rubber soft joints, flexible joints, high-pressure rubber joints, rubber shock absorbers, etc. According to the connection mode, there are three types: loose flange type, fixed flange type and threaded type; according to the structure, it can be divided into single sphere, double sphere, curved sphere, etc. Tubular rubber parts are composed of inner and outer layers of rubber, cord layer and wire ring, which are vulcanized and formed and then combined with metal flanges or parallel joint loose sleeves. This product can reduce vibration and noise, and can compensate for thermal expansion and contraction caused by temperature changes, and 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. This product takes advantage of rubber's elasticity, high air tightness, medium resistance, weather resistance and radiation resistance, etc. After being cross-compounded with polyester cord fabric with high strength and strong cold and heat stability, it undergoes high pressure, It is vulcanized by high temperature mold. Because the rubber joint has good comprehensive performance, it mainly plays the role of shock absorption, noise reduction and noise reduction. Therefore, it is widely used in basic projects such as chemical industry, construction, water supply, drainage, petroleum, light and heavy industry, refrigeration, sanitation, plumbing, fire fighting, and electric power.
