Double Sphere Rubber Expansion Joint Connection Type of NBR Rubber
Expansion Joint
NBR rubber expansion joint particularly when constructed with Nitrile Butadiene Rubber (NBR),
represents a highly specialized and robust piping system component.
This type of joint is designed to accommodate thermal expansion,
absorb vibration, and reduce noise in a wide range of industrial
applications. The use of NBR rubber enhances its resistance to
oils, fuels, and other hydrocarbons, making it ideal for use in
environments where such substances are present.
Performance characteristics of NBR Rubber Expansion Joint
NBR 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, NBR 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 NBR rubber expansion joint made? Let's see with JINGNING.
It is very important to select the appropriate NBR rubber expansion joint, to understand the compatibility of the medium and the selected
material of the NBR rubber 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 NBR rubber expansion joint for any application.
NBR Rubber Expansion Joint application
NBR 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. NBR 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 NBR rubber expansion joint has high wear resistance, jNBR rubber expansion joint is also suitable for all industries of granular and powdery and gas
low temperature.
