Double Sphere Rubber Expansion Joint Type of EPDM Vulcanized Rubber
Expansion Joint
The connection type of the vulcanized rubber expansion joint with NBR rubber typically involves the use of flanges. These
flanges can be made of various materials, such as stainless steel
or carbon steel, depending on the specific application and
environmental conditions. The flanges are designed to fit securely
with the piping system, ensuring a leak-proof and reliable
connection. Vulcanized rubber expansion joint is a versatile and robust component for piping systems in various
industrial applications. Its oil and fuel resistance, high
flexibility, temperature resistance, and noise and vibration
reduction capabilities make it an essential element in ensuring the
smooth and efficient operation of piping systems.
Performance characteristics of Vulcanized Rubber Expansion Joint
Vulcanized rubber 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, vulcanized rubber expansion joint are able to:
1. Reduce mechanical noise
2. Compensate for eccentricity
3. Eliminate electrolysis between dissimilar metals

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 Vulcanized Rubber Expansion Joint made? Let's see with JINGNING.
It is very important to select the appropriate joint expansion, to understand the compatibility of the medium and the selected
material of the joint expansion, 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 joint expansion for any application.
Vulcanized Rubber Expansion Joint application
Vulcanized rubber expansion joint are widely used in various pipeline systems, such as the
connection of joint expansion with pumps and valves, fire-fighting equipment and pipelines with
large vibration. Pipes with frequent changes of heat and cold.
Vulcanized rubber 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
vulcanized rubber expansion joint has high wear resistance, vulcanized rubber expansion joint is also suitable for all industries of granular and powdery
and gas low temperature.
