EPDM Galvanized Double Sphere Flexible Bellow Rubber Expanison
Joint
Bellow rubber can also be called fan coil rubber joint, screw
rubber soft joint, screw rubber soft joint, screw rubber soft joint
and so on. Bellow rubber is composed of inner rubber, multi-layer scraper cord fabric
reinforcement, outer rubber tube and metal movable joint.
Performance characteristics of bellow rubber
1. High pressure of bellow rubber
2. The bellow rubber has good elasticity
3. The bellow rubbert has large deflection displacement
4. Aging resistance of bellow rubber
5. Good vibration absorption of bellow rubber

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.

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
The bellow rubber 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. Bellow rubbers are also suitable for factory and residential plumbing systems,
as well as circulating water pipes, sanitary pipes, chemical
anti-corrosion and freezing pipes, etc.
