Bellows type expansion joint flexible rubber expansion joint
Bellows type expansion joint can also be called fan coil rubber joint, screw rubber soft joint, screw rubber soft joint, screw rubber soft joint and so on. Bellows type expansion joint is composed of inner rubber, multi-layer scraper cord fabric reinforcement, outer rubber tube and metal movable joint.
Performance characteristics of bellows type expansion joint
1. The bellows type expansion joint can reduce the noise produced by the vibration of the pipeline pump, and has strong damping capacity.
2. The bellows type expansion joint is easy to install and operate, simple and flexible.
3. The bellows type expansion joint is a kind of inner seamless high pressure rubber joint made of rubber soft joint. The bellows type expansion joint can effectively prevent the corrosion of the inner wall of rubber soft joint caused by high temperature resistance, acid and alkali resistance and corrosion medium in oil resistant pipeline, and improve the service life.
4. After the bellows type expansion joint is installed, it can absorb the lateral, axial and angular displacement caused by the vibration of the pipeline. The bellows type expansion joint is not limited by the imbalance of the pipe with the neutral flange.

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

Bellows type expansion joint production Flow
Do you know how is a bellows type expansion joint made?Let's see with JINGNING.
It is very important to select the appropriate bellows type expansion joint 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 bellows type expansion joint for any application.
Bellows type expansion joint advantage
1. The bellows type expansion joint is galvanized for 15 minutes, resistant to high pressure, high temperature, oil, wear, corrosion, acid and alkali.
2. Bellows type expansion joint 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 bellows type expansion joint 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 bellows type expansion joint 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 bellows type expansion joint. Bellows type expansion joint is characterized by perfect combination of inner rubber layer, bright, clean and seamless; the label of bellows type expansion joint adopts vulcanization process, which perfectly matches the ball of bellows type expansion joint.
Bellows type expansion joint application
The bellows type expansion joint is suitable for connecting the inlet and outlet pipes of all kinds of fan coil units for air conditioning in hotels and other guest rooms. Bellows type expansion joints are also suitable for factory and residential plumbing systems, as well as circulating water pipes, sanitary pipes, chemical anti-corrosion and freezing pipes, etc.
