Flanged Connector Coupling Pipeline EPDM Flexible Expansion Rubber Joint

 

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

 

Performance characteristics of expansion rubber​ joint

 

Properties of expansion rubber​, such as high elasticity, high air tightness, medium resistance, weather resistance and radiation resistance, etc. The expansion rubber​ is made of polyester cord fabric with high strength and strong cold and hot stability, which is cross compounded with it. After high pressure and high temperature molding and crosslinking, expansion rubber​ is resistant to forming. The expansion rubber​ has high internal density, can withstand high pressure and excellent elastic deformation effect. The expansion rubber​ structure design section arc height, long curve, has a large multi-directional displacement function. Expansion rubber​ is especially suitable for places with complex geological conditions, large settlement radiance and frequent cold and hot changes during pipeline operation, which are easy to cause pipeline operation. The expansion rubber​ can effectively eliminate the displacement and physical damage of the pump, valve and pipeline itself by using the elastic sliding of rubber and the heat transfer function of deformation mechanical force. Because the rubber of the expansion rubber​ is a bad conductive material, the expansion rubber​ is an ideal environmental protection product for reducing vibration and noise transmission.

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

It is very important to know the compatibility between the medium of expansion rubber and the selected expansion rubber material, the range of full temperature, full pressure and full vacuum, the required movement of expansion rubber, and the size between pipe flanges when selecting the appropriate flexible joint pipe. With this information, JINGNING application engineers can help determine the ideal expansion rubber for any application.

 

Expansion rubber advantage

 

1. Factory price of  expansion rubber.

2. 16 years of manufacturing experience, 5 years of export experience.

3. Strict quality inspection, the quality far exceeds the industry standard.

4. Expansion rubber mold has a variety of specifications, support customization, OEM.

5. Provide free samples of expansion rubber.

Expansion rubber application

 

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