DN50 EPDM Single Sphere Rubber Expansion Joint SS304 Metal Flanged Expand Joint

Flanged expand joint can also be called: joint expansion, flexible joint, pipe expansion joint, flexible connectors. it is a pipe connector with high elasticity, high air tightness, medium resistance and weather resistance. Flanged expand joint 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 flanged expand joint makes use of the advantages of rubber, such as high elasticity, high gas resistance, medium resistance, weather resistance and radiation resistance. Flanged expand joint can reduce the vibration and noise of the pipeline, and compensate the thermal expansion and cold contraction caused by temperature change.

Performance characteristics of flanged expand joint

Flanged expand joint offer ultra-high performance, reliability and longevity, thus improving plant safety and the mechanical integrity of equipment. Due to the insertion of specially designed products in rigid piping systems, Flanged expand joint are able to:
1. Reduce displacement
2. Improve thermal stability
3. Release system strains caused by thermal variations, load stresses, pump pressure fluctuations, and sediment wear

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

Flanged expand joint production Flow

Do you know how is a flanged expand joint made? Let's see with JINGNING.

It is very important to select the appropriate flanged expand joint, to understand the compatibility of the medium and the selected material of the flanged expand joint, the range of full temperature, full pressure and full vacuum, the amount of movement required, and the size between the pipe flanges. With this information, JINGNING application engineers can help determine the ideal flanged expand joint for any application.

Flanged expansion joint application

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