EPDM Single Sphere Rubber Expansion Joint Flange Type Small Volume
Single Sphere Rubber Expansion Joints are also called rubber
joints, rubber flexible joints, soft joints, shock absorbers,
pipeline shock absorbers, shock-absorbing throats, etc. They are a
kind of high elasticity, high air tightness, medium resistance and
weather resistance. Pipe joints.
Performance characteristics of Single Sphere Rubber Expansion Joint
1. It has the advantages of small volume, light weight, good
ductility, convenient installation and maintenance, etc.
2. Installation can cause horizontal, radial and angular offset,
which is not limited by the uneven center of pipe plug and flange
surface.
3. When working, it can reduce the noise transmitted by the
structure and has strong damping capacity.

Note: The special requirements of bellows expansion joint can be
customized according to 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 axial expansion joint can be used as natural rubber,
EPDM, chloroprene rubber, butyl rubber, butadiene rubber,
fluororubber, etc. when the axial expansion joint above DN200 is
used for suspension water supply, the pipeline must have fixed
support or fixed support, otherwise the axial expansion joint shall
be installed with anti falling device.

It is very important to know the compatibility between the medium
of axial expansion joint and the selected expansion rubber
material, the range of full temperature, full pressure and full
vacuum, the required movement of axial expansion joint, and the
size between pipe flanges when selecting the appropriate flexible
joint pipe. With this information, JINGNING application engineers
can help determine the ideal axial expansion joint for any
application.
Bellows expansion joint advantage
1. Ex factory price of axial expansion joint.
2. 16 years of manufacturing experience and 5 years of export
experience.
3. Strict quality inspection, the quality far exceeds the industry
standard.
4. The mold has a variety of specifications and supports
customization and OEM.
5. Provide samples free of charge.
6. Large inventory.
Bellows expansion joint application
Bellows expansion joints are widely used in various pipeline
systems, such as the connection between axial expansion joints and
pumps, valves, fire-fighting equipment and pipelines with large
vibration. Pipes 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. Because the axial expansion joint has high wear
resistance, it is also suitable for all particle, powder and gas
low-temperature industries.
