DN65 Flanged Single Sphere Rubber Expansion Joint PN16 Single
Sphere Expansion Joint
The Single Sphere Rubber Flexible Joint features a single spherical
rubber bellows lined with EPDM rubber and interconnected with SS304
stainless steel flanges. The bellows are made of high-quality EPDM
rubber, which is known for its excellent resistance to ozone,
weathering, and a wide range of chemicals, including acids, bases,
and alcohols. The SS304 flanges provide structural support and
ensure a secure and corrosion-resistant connection to the piping
system.
Performance characteristics of Single Sphere Expansion Joint
Single sphere expansion 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, Single sphere expansion 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 Single Sphere Expansion Joint made? Let's see with JINGNING.
It is very important to select the appropriate single sphere expansion joint, to understand the compatibility of the medium and the
selected material of the single sphere expansion 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 single sphere expansion joint for any application.
Single Sphere Expansion Joint application
Single sphere expansion joints are widely used in various pipeline systems, such as the
connection of single sphere expansion joints with pumps and valves, fire-fighting equipment and pipelines
with large vibration. Pipes with frequent changes of heat and cold.
Single sphere expansion 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 single sphere expansion joint has high wear resistance, single sphere expansion joint is also suitable for all industries of granular and powdery
and gas low temperature.
