Bellows flange jiont
The limit device of bellows flange joint shall be reasonably matched with the flexible rubber joint. When it is used for general connection of pipelines or pipelines with displacement requirements, the positioning displacement can be limited. When the flexible rubber joint is connected with the pump and valve, a limit device shall be installed on the rubber joint to transfer force. It is an ideal substitute for steel force transmission joint.
Performance characteristics of bellows flange joint
1. Excellent rupture pressure resistance.
2. Excellent shock absorption and noise reduction performance
3. Compensate for greater elongation, compression, lateral and angular movement.

Note:To select the proper piping limit flexible rubber joint, it is critical to understand the media compatibility with the materials selected, full temperature, pressure and vacuum ranges, movements required, and dimensions between pipe flanges. With this information, JINGNING application engineers can assist in determining the ideal expansion joint for any application.
Bellows flange joint production flow
Do you know how is a high quality bellows flange joint made?Let's see with JINGNING.
Bellows flange joint application
Bellows flange joint are widely used in new joints, pipeline desulfurization and dust removal, water supply and drainage, chemical industry, water conservancy and hydropower and other industries. It is used to transport air, compressed air, water, seawater, oil, acid, alkali, etc. at - 15 ℃ ~ 115 ℃. The joint made of special rubber can also be used to transport the above media or oil, concentrated acid, concentrated alkali and solid materials above - 30 ℃ ~ 250 ℃.
