Flexible expansion joints are often referred to as rubber joints. Flexible expansion joints are widely used in water, electricity, chemical industry and ship mooring systems. According to different media, the rubber materials used in flexible expansion joints are also different, including NR, SBR, IIR, NBR, EPDM, Cr, fkr, etc. Flexible expansion joints have heat resistance, acid resistance, alkali resistance, corrosion resistance and oil resistance. The structural material of the rubber joint is nylon cord fabric, and the inner and outer surfaces are made of high-strength aging resistant polar rubber. In order to prevent natural shrinkage of flexible expansion joints in long-term use and reduce aging and fracture, steel wires are used for multiple protection of rubber joints.

 

Performance characteristics of flexible expansion joint

 

1. The flexible expansion joints for pipe has high wear resistance, acid and alkali resistance, etc.

2. Flexible expansion joints for pipe can reduce vibration and reduce pressure, reduce noise.

3. Flexible expansion joints for pipe has unique properties, such as high elasticity, high air tightness, medium resistance and corrosion resistance.

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

Flexible expansion joint application

 

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