Rubber expansion joints are quite versatile

The application range of rubber expansion joints are better in heat and acid resistance, alkali resistance, high and low temperature resistance and other chemical properties. It can also absorb vibration, expansion and contraction displacement, and has a certain axial sealing effect. It is widely used in chemical, petroleum, food and other industries. And it is widely used in various fields.
Structure parameters sphere is made of shaped rubber, its outer diameter is generally 225 mm, inner diameter is 320 mm.(2) Single sphere is made of middle rubber layer and outer rubber, with good compressive strength; between single sphere and middle rubber layer can be processed by special vulcanization process to form a rubber ring, so that the rubber ring has the function of compensating displacement in both axial and lateral directions; with good vibration and noise reduction. effect. The sphere is composed of middle rubber layer and outer rubber layer; it is made by assembling bolts between the spheres; the sphere is made of common rubber; it is made by combining inner and outer rubber. (Rubber joint is a kind of pipe axial displacement reduction and axial sealing effect (or axial vibration and noise reduction), compensation of pipeline axial displacement and radial load with vibration and noise reduction function (or vibration reduction effect); good sound absorption and vibration reduction performance (or sound absorption effect), suitable for installation and use in the pipeline support system where the vibration is large, and its axial displacement is less than or equal to 0.5 mm.
Installation precautions Because rubber joints must have proper installation height, they must be installed on horizontal or vertical pipes. Pay attention to the alignment of the threaded holes on the flanges during installation to avoid loosening of the bolts during installation. Do not rotate the rotary joint in the axial direction to prevent the rotary joint from sliding and causing pipeline displacement; when installing the rubber joint, pay attention to whether the type of pipeline installed meets the design requirements, as improper installation can cause serious consequences of pipeline displacement; if leakage is found in use, stop using the joint in time or take corresponding measures to prevent accidents.
