high quality epdm rubber axial expansion joint

 

Axial expansion joint is also known as rubber bellows, rubber joint, single ball flexible connection, expansion joint bellows, etc. The axial expansion joint is mainly composed of two PCs flanges and a rubber ball. Flanges are used for connection. The rubber ball is flexible and can absorb axial, horizontal and annular displacement. The normal working pressure of the axial expansion joint is 16bar, the normal working temperature of the axial expansion joint is - 15 ~ + 90 ℃, the standard size of the axial expansion joint is dn25-dn3000, the standard rubber materials are natural rubber, EPDM, neoprene, nitrile rubber and polytetrafluoroethylene, and the standard flange materials are carbon steel galvanized, carbon steel painted, cast iron painted and stainless steel. Of course, if you have any special requirements, please let us know and we will recommend a good solution to you.

 

Performance characteristics of axial expansion joint

 

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

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

3. When the axial expansion joint is working, it can reduce the structure transmission noise and has strong vibration absorption ability.

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

Axial expansion joint application

 

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