SS304 Flange Rubber Flexible Joint Single Sphere Expansion Joint
Rubber flexible joint is a tubular rubber part composed of inner and outer rubber, cord and steel ring. After high temperature and high pressure vulcanization, the rubber flexible joint is loosely combined with metal flange or parallel joint.
The rubber flexible joint makes use of the advantages of rubber, such as high elasticity, high gas resistance, medium resistance, weather resistance and radiation resistance. The rubber flexible joint can reduce the vibration and noise of the pipeline, and can compensate the thermal expansion and cold contraction caused by the change of temperature. Rubber flexible joints are widely used in chemical industry, construction, water supply, drainage, petroleum, light and heavy industry, refrigeration, cleaning, water heating, fire protection, electric power and other basic projects.
Performance characteristics of rubber flexible joint
1. The rubber flexible joint has the advantages of small volume, light weight, good elasticity and convenient installation and maintenance.
2. The rubber flexible joint can produce transverse, axial and angular displacement when it is installed, which is not limited by the pipe centerless and non parallel flange.
3. When the rubber flexible joint works, it can reduce the structure transmission noise and has strong vibration absorption ability.

Note: 1. The special requirements of rubber flexible joint can be customized according to user's drawing. Flange standard is GB / t9115.1-2000. Various flange standards (GB, JB, Hg, CB, ANSI, DIN, BSEN, NF, en, JIS, ISO, etc.) can be selected for production. The rubber ball of rubber flexible joint can be used as natural rubber, EPDM, chloroprene rubber, butyl rubber, butadiene rubber, fluororubber, etc. when the rubber flexible joint above DN200 is used for suspension water supply, the pipeline must have fixed support or fixed support, otherwise the rubber flexible joint shall be installed with anti falling device.
