DN50 EPDM Single Sphere Rubber Expansion Joint SS304 Metal Flanged
Expand Joint
Flanged expand joint can also be called: joint expansion, flexible joint, pipe
expansion joint, flexible connectors. it is a pipe connector with
high elasticity, high air tightness, medium resistance and weather
resistance. Flanged expand joint is a kind of composite rubber pipe which is composed of inner
rubber layer, fabric reinforcement layer (the reinforcement layer
has multi-layer scraped nylon cord), middle rubber layer, outer
rubber layer, end reinforced metal ring or steel ring, and loose
combination with metal flange or parallel joint after high
temperature and high pressure vulcanization. The flanged expand joint makes use of the advantages of rubber, such as high elasticity,
high gas resistance, medium resistance, weather resistance and
radiation resistance. Flanged expand joint can reduce the vibration and noise of the pipeline, and compensate
the thermal expansion and cold contraction caused by temperature
change.
Performance characteristics of flanged expand joint
Flanged expand joint offer ultra-high performance, reliability and
longevity, thus improving plant safety and the mechanical integrity
of equipment. Due to the insertion of specially designed products
in rigid piping systems, Flanged expand joint are able to:
1. Reduce displacement
2. Improve thermal stability
3. Release system strains caused by thermal variations, load
stresses, pump pressure fluctuations, and sediment wear

Note: 1. The special requirements of flanged 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 flanged expansion joint can be used as natural rubber, EPDM, chloroprene rubber, butyl
rubber, butadiene rubber, fluororubber, etc. when the flanged expansion joint above DN200 is used for suspension water supply, the pipeline must
have fixed support or fixed support, otherwise the flanged expansion joint shall be installed with anti falling device.

Do you know how is a flanged expand joint made? Let's see with
JINGNING.
It is very important to select the appropriate flanged expand joint, to understand the compatibility of the medium and the selected
material of the flanged expand joint, the range of full
temperature, full pressure and full vacuum, the amount of movement
required, and the size between the pipe flanges. With this
information, JINGNING application engineers can help determine the
ideal flanged expand joint for any application.
Flanged expansion joint application
Flanged expand joints are widely used in various pipeline systems,
such as the connection of flanged expand joints with pumps and valves, fire-fighting equipment and pipelines with
large vibration. Pipes with frequent changes of heat and cold.
Flanged expand joint is mainly used for remote water and sewage lifting and
transportation, water supply and cooling circulating water of
thermal power plant, pipeline transportation of metallurgical
industry, condensate water, chemical industry, cooling and dilution
of petrochemical industry, and flexible connection between long and
short distance pipelines in other industries. Because the flanged
expand joint has high wear resistance, flanged expand joint is also
suitable for all industries of granular and powdery and gas low
temperature.
