EPDM Threaded Expansion Joint
EPDM threaded expansion joint can also be called fan coil rubber
joint, spiral rubber soft joint, spiral rubber soft joint, spiral
rubber soft joint, etc. It is composed of inner rubber, multi-layer
scraper cord reinforcement, outer rubber pipe and metal movable
joint.
Performance characteristics of EPDM threaded expansion joint
1. Reduce the noise caused by pipeline pump vibration and have
strong damping capacity.
2. Convenient installation and operation, simple and flexible.
3. It is an internal seamless high-pressure rubber joint made of
rubber soft joint, which can effectively prevent the corrosion of
high temperature resistant, acid and alkali resistant and corrosive
medium in oil resistant pipeline to the inner wall of rubber soft
joint and improve the service life.
4. After installation, it can absorb the lateral, axial and angular
displacement caused by pipeline vibration and is not limited by the
imbalance between the pipeline and the neutral flange.

Note: If there are special requirements, it can be customized
according to the user's 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 natural rubber, ethylene propylene diene
monomer rubber, neoprene, butyl rubber, butadiene rubber,
fluororubber, etc.

EPDM threaded expansion joint production Flow
Selecting a suitable pipe joint requires understanding the
compatibility of the medium with the selected material, the full
temperature, pressure and vacuum range, the required movement and
the size between pipe flanges. With this information, Jingning
application engineers can help determine the ideal rubber joint for
any application.
EPDM threaded expansion joint advantage
1. Galvanized for 15 minutes, resistant to high pressure, high
temperature, oil, wear, corrosion, acid and alkali.
2. Connect with pumps, valves, fire-fighting equipment, pipes with
large vibration and pipes with frequent changes in cold and heat.
3. The content of natural rubber is 47%, which can be used
continuously for 15 years without aging.
We introduce foreign advanced technology and combine China's
production experience. In the manufacturing operation of rubber
joint, the inner side bears high pressure, and the combination of
nylon rope and inner rubber is better, which can bear higher
pressure than ordinary bellows expansion joint. It is characterized
by the perfect combination of internal rubber layer, bright, clean
and seamless; Its label adopts vulcanization process, which is
perfectly matched with the sphere.
EPDM threaded expansion joint application
EPDM threaded expansion joint is suitable for connecting the inlet
and outlet pipes of various fan coils for air conditioning in
hotels and other guest rooms. It is also applicable to factory and
residential pipeline systems, as well as circulating water pipes,
sanitary pipes, chemical anti-corrosion and refrigeration pipes.
