Note: 1. The special requirements of bellow rubber 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 bellow rubber can be used as natural rubber, ethylene propylene diene monomer rubber, chloroprene rubber, butyl rubber, butadiene rubber, fluorine rubber, etc. When the bellow rubber above DN200 is used for suspended water supply, the pipe must have fixed support or fixed support, otherwise the bellow rubber shall be installed with anti falling device.


Typical installation

The installation in the piping of the anti-vibration joints near of pumps, compressors, control devices, valves, operating machines, etc., allows to interrupt the propagation of sound waves and to absorb small vibrations.


Bellow rubber production Flow


Do you know how is a bellow rubber made?Let's see with JINGNING.

It is very important to select the appropriate bellow rubber of the pipeline, understand the compatibility of the medium with the selected material, the full temperature, pressure and vacuum range, the required movement and the size between the pipeline flanges. With this information, Jingning application engineers can help determine the ideal bellow rubberfor any application.


Threaded rubber expansion joint advantage


1. The bellow rubber is galvanized for 15 minutes, resistant to high pressure, high temperature, oil, wear, corrosion, acid and alkali.

2. Bellow rubber are connected with pumps, valves, fire-fighting equipment, pipes with large vibration and pipes with frequent changes of cold and heat.

3. The natural rubber content of bellow rubber is 47%, which can be used continuously for 15 years without aging.

We introduce foreign advanced technology and combine with China's production experience. In the bellow rubber manufacturing operation, the inner side bears high pressure, and the nylon cord and the inner side rubber are combined better, which can bear higher pressure than the ordinary bellow rubber. Bellow rubber is characterized by perfect combination of inner rubber layer, bright, clean and seamless; the label of bellow rubber adopts vulcanization process, which perfectly matches the ball of bellow rubber.


Bellow rubber application


Heating, water pumping, air-conditioning, for installations such as apartment buildings, hospitals, schools, etc.. Compatible fluids: water, sea water, weak acids and bases, and so on.
Maximum operating pressure: 10 bar
Max continuous operating temperature: +100 ° C.
