Flexible Single Ball Bellow Compensator Epdm Rubber Expansion Joints
Rubber expansion joints joint can also be called: flexible rubber joint, rubber soft joint, soft joint, flexible rubber joint, etc. Rubber expansion joints is a pipe connector with high elasticity, high air tightness, medium resistance and weather resistance. Rubber 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 rubber expansion joints makes use of the advantages of rubber, such as high elasticity, high gas resistance, medium resistance, weather resistance and radiation resistance. Rubber expansion joints can reduce the vibration and noise of the pipeline, and compensate the thermal expansion and cold contraction caused by temperature change.
Performance characteristics of rubber expansion joints
1. The rubber expansion joints for pipe has high wear resistance, acid and alkali resistance, etc.
2. Rubber expansion joints for pipe can reduce vibration and reduce pressure, reduce noise.
3. Rubber 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 rubber expansion joints 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 rubber expansion joints can be used as natural rubber, EPDM, chloroprene rubber, butyl rubber, butadiene rubber, fluororubber, etc. when the rubber expansion joints above DN200 is used for suspension water supply, the pipeline must have fixed support or fixed support, otherwise the rubber expansion joints shall be installed with anti falling device.

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