    DN40-600 Rubber Expansion Bellows EPDM Flexible Rubber Joint

    Rubber Expansion Bellows DN40-600 EPDM Flexible Rubber Joint


    Expansion bellows is commonly known as rubber joint. Expansion bellows is widely used in water, electricity, chemical industry and ship mooring system. The expansion bellows can be automatically extended with the natural change of weather during use. The structural material of the expansion bellows is nylon cord fabric, and the inner and outer surfaces are made of high strength aging resistant polar rubber. In order to prevent the natural shrinkage and reduce the aging fracture of expansion bellows in long-term use, steel wire is used for multiple protection.


    Performance characteristics of expansion rubber​ joint


    1. The expansion bellows has the advantages of small size, light weight, good ductility and convenient installation and maintenance.

    2. Expansion bellows installation can cause horizontal, radial, angular offset, will not be limited by the pipe plug center, flange uneven surface.

    3. When theexpansion bellows is working, it can reduce the structure transmission noise and has strong vibration absorption ability.

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

    Expansion bellows application


    Expansion bellows are widely used in various pipeline systems, such as the connection of expansion bellows with pumps and valves, fire-fighting equipment and pipelines with large vibration. Pipes with frequent changes of heat and cold. Expansion bellows 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 expansion bellows has high wear resistance, expansion bellows is also suitable for all industries of granular and powdery and gas low temperature.
