FKM Flanged Rubber Expansion Joint Single Sphere High Elasticity
Rubber Expansion Joint is also called flange rubber joints, rubber
quick joints, etc. This Rubber Expansion Joint is a flexible
connector for metal pipes, which is composed of an inner rubber
layer, nylon cord fabric reinforcement, a rubber sphere compounded
by an outer rubber layer, and a loose metal flange.
Performance characteristics of Flanged Rubber Expansion Joint
1. High elasticity
2. High gas resistance
3. Medium resistance
4. Weather resistance
5. Radiation resistance

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

Bellow joints production flow
Do you know how is a bellow joints made?Let's see with JINGNING.
When selecting a suitable flexible joint pipe, it is very important
to understand the compatibility between the joint expansion medium
and the selected expansion rubber material, the full temperature,
full pressure and full vacuum range, the required joint expansion
movement and the size between pipe flanges. With this information,
Jingning application engineers can help determine the ideal
expansion joint for any application.
Bellow joints advantage
