EPDM double ball Expansion Joint

EPDM double ball expansion rubber bellows

 

The double ball rubber joint is composed of inner rubber layer, nylon cord fabric reinforcing layer, outer composite rubber ball and metal flange. The multi wave design increases the length of the double ball rubber joint and the amount of compensation. It makes full use of the high elasticity and high air tightness of raw rubber, so that it has high internal density, can withstand high pressure and has good elastic deformation effect. With unique design, novel structure and good sealing performance, it solves the pipeline burst caused by thermal expansion and cold contraction and the damage of pipeline connecting equipment, and effectively improves the service life of pipeline and the protection of equipment.

 

Expansion rubber bellows characteristics

 

1. The ball itself is designed to be longer than the single ball rubber joint, which has good vibration and noise reduction effect

2. Good telescopic displacement performance and longer service life than single ball rubber joint

3. Small volume, light weight, good flexibility and convenient installation and maintenance

4. After installation, it can absorb the lateral, axial and angular displacement caused by pipeline vibration; It is not limited by the concentricity of the pipeline and the non parallelism of the flange, which can reduce the noise generated by the vibration of the pipeline, water pump and so on

5. The flexibility of raw materials is good. Choosing different rubber materials can make it more effectively used in various pipelines, effectively prevent the corrosion of corrosive medium on the inner wall of rubber joint, and prolong the service life

Note: 1. The special requirements of expansion rubber bellows can be customized according to the 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 three ball rubber joint can be used as natural rubber, ethylene propylene diene monomer rubber, chloroprene rubber, butyl rubber, butadiene rubber, fluorine rubber, etc. when the three ball rubber joint of DN200 and above is used for suspended water supply, the pipeline must have fixed support or fixed support, otherwise three ball rubber joint should be installed with anti falling device.

Expansion rubber bellows OEM&ODM

 

How to choose the right rubber joint? It is necessary to understand the compatibility between the medium and the selected material, the range of full temperature, full pressure and full vacuum, the amount of movement required and the size between pipe flanges. With this information, Jingning application engineers can help determine the ideal rubber joint for any application.
