Neoprene Bellows Rubber Expansion Flexible Joint Coupling
The bellows rubber for pipe is made of high-strength, cold and hot stable polyester cord, which is cross-linked by high-pressure and high-temperature molding. The internal density of the bellows rubber for pipe is high, and it can withstand high pressure. The elastic deformation effect of the bellows rubber for pipe is excellent. The product structure is designed with high end arc and long curve, and the bellows rubber for pipe has a large number of displacement functions.
Performance characteristics of bellows rubber
1. The bellows rubber has the advantages of small volume, light weight, good elasticity and convenient installation and maintenance.
2. After installation, the bellows rubber can absorb the lateral, axial and angular displacement caused by the vibration of the pipeline, and is not limited by the non concentric pipeline and non parallel flange.
3. After the bellows rubber is installed, the noise caused by the vibration of the pipeline water pump can be reduced, and the vibration absorption ability is strong.
4. The inner seamless high pressure bellows rubber can effectively prevent the corrosive medium from eroding the inner wall of the rubber joint in the high temperature resistant, acid alkali resistant and oil resistant pipeline, and improve the service life.

Note: 1. The special requirements of bellows rubber 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 bellows rubber can be used as natural rubber, EPDM, chloroprene rubber, butyl rubber, butadiene rubber, fluororubber, etc. when the bellows rubber above DN200 is used for suspension water supply, the pipeline must have fixed support or fixed support, otherwise the bellows rubber shall be installed with anti falling device.

Bellows rubberr application
Bellows rubbers are widely used in various pipeline systems, such as the connection of bellows rubbers with pumps and valves, fire-fighting equipment and pipelines with large vibration. Pipes with frequent changes of heat and cold. Bellows rubber is mainly used for remote water and sewage lifting and transportation, water supply and cooling circulating water of thermal power plant, pipeline transportation of metallurgical industry, condensate water, chemical industry, cooling and dilution of petrochemical industry, and flexible connection between long and short distance pipelines in other industries. Because the bellows rubber has high wear resistance, bellows rubber is also suitable for all industries of granular and powdery and gas low temperature.
