Corrosion Resistant Single Sphere Connector Flexible Joint Expansion Bellows
Joint expansion can also be called: flexible rubber joint, rubber soft joint, soft joint, flexible rubber joint, etc. Joint expansion is a pipe connector with high elasticity, high air tightness, medium resistance and weather resistance. Joint expansion is a kind of composite rubber pipe which is composed of inner rubber layer, fabric reinforcement layer (the reinforcement layer has multi-layer scraped nylon cord), middle rubber layer, outer rubber layer, end reinforced metal ring or steel ring, and loose combination with metal flange or parallel joint after high temperature and high pressure vulcanization. The joint expansion makes use of the advantages of rubber, such as high elasticity, high gas resistance, medium resistance, weather resistance and radiation resistance. Joint expansion can reduce the vibration and noise of the pipeline, and compensate the thermal expansion and cold contraction caused by temperature change.
Performance characteristics of joint expansion
1. The joint expansion has the advantages of small size, light weight, good ductility and convenient installation and maintenance.
2. Joint expansion installation can cause horizontal, radial, angular offset, will not be limited by the pipe plug center, flange uneven surface.
3. When the joint expansion is working, it can reduce the structure transmission noise and has strong vibration absorption ability.

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

Joint expansion production flow
Do you know how is a joint expansion made?Let's see with JINGNING.
It is very important to know the compatibility between the medium of joint expansion and the selected expansion rubber material, the range of full temperature, full pressure and full vacuum, the required movement of joint expansion, and the size between pipe flanges when selecting the appropriate flexible joint pipe. With this information, JINGNING application engineers can help determine the ideal joint expansion for any application.

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