Product Description

Single sphere bellows expansion joint

 

Bellows expansion joints are often referred to as rubber joints. Flexible expansion joints are widely used in water, electricity, chemical industry and ship mooring systems. According to different media, the rubber materials used for flexible expansion joints are also different, including NR, SBR, IIR, NBR, EPDM, Cr, fkr, etc. Flexible expansion joints have heat resistance, acid resistance, alkali resistance, corrosion resistance and oil resistance. The structural material of the rubber joint is nylon cord fabric, and the inner and outer surfaces are made of high-strength aging resistant polar rubber. In order to prevent the natural shrinkage of flexible expansion joints in long-term use and reduce aging and fracture, steel wires are used for multiple protection of rubber joints.

 

Performance characteristics of bellows expansion joint

 

1. It has the characteristics of high wear resistance, acid and alkali resistance, etc.

2. It can reduce vibration, pressure and noise.

3. It has high elasticity, high air tightness, medium resistance, corrosion resistance and other unique properties.

Note: special requirements can be customized according to user drawings. The 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. Rubber balls can be used as natural rubber, EPDM, neoprene, butyl rubber, butadiene rubber, fluororubber, etc. When the flexible expansion joint above DN200 is used for suspended water supply, the pipeline must have fixed support or fixed support, otherwise the flexible expansion joint shall be equipped with anti falling device.

When selecting a suitable pipe joint, it is very important to understand the compatibility between the joint medium and the selected joint material, the range of full temperature, full pressure and full vacuum, the movement required by the joint and the size between pipe flanges. With this information, Jingning application engineers can help determine the ideal expansion joint for any application.

 

Bellows expansion joint advantage

 

1. The price is the ex factory price.

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

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

4. It has a variety of specifications and supports customization and OEM.

5. Provide samples free of charge.

6. Large inventory.

 

Bellows expansion joint application

 

The product is widely used in various pipeline systems, such as the connection with pumps and valves, fire-fighting equipment and pipelines with large vibration, and pipelines with frequent changes in cold and heat. It is mainly used for the lifting and transportation of remote water and sewage, water supply and cooling circulating water of thermal power plants, pipeline transportation in metallurgical industry, condensate water, pipeline transportation in chemical industry, cooling and dilution in petrochemical industry, and flexible connection between long-distance and short-distance pipelines in other industries. Due to its high wear resistance, it is also suitable for all industries with low temperature of particles, powders and gases.
