EPDM Single Sphere Flexible Expansion Joint

Flexible expansion joint can also be called: flexible rubber joint, rubber soft joint, soft joint, flexible rubber joint, etc. Flexible expansion joint is a pipe connector with high elasticity, high air tightness, medium resistance and weather resistance. Flexible expansion 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 Flexible expansion joint makes use of the advantages of rubber, such as high elasticity, high gas resistance, medium resistance, weather resistance and radiation resistance. Flexible expansion 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 flexible expansion joint

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

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

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

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 s 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.
