flexible bellow union rubber expansion joint
Screwed type flexible rubber joints are designed to absorb movements and stress on piping systems, compensate for pipe misalignment, reduce vibration and system noise, protect against start-up forces as well as system surges. Thus, they are also called sh
- [Name]: JGD-BW•N Fan coil rubber joint
- [PN]: 0.6~2.5Mpa
- [Medium]: Air, water, seawater, oil, slurry, weak acid, alkali, etc.
- [Material]: NR, NBR, CR, EPDM, PTFE etc.
Description
The double convoluted bellow rubber expansion joints compensate for in every direction vibrations and strong voices due to the soft skeleton structure; products that reduce stress and axial imbalance in the system.The operating pressure depends on the nomimal diameter and operating temperature.
Female threaded threaded rubber couplings are constructed with a high-quality EPDM tube and cover and nylon tire cord reinforcing.
Neoprene construction without cables is also available.Female threaded threaded rubber couplings offer high-temperature EPDM rubber
for tube and cover construction. Galvanized ductile iron threaded female union ends are standard. Special cable restraint attachments
surround each end to prevent the connector from over-extending due to pressure thrust. A steel body ring encircles the rubber between
the spheres to provide stability under pressure.
Features
1. This product can greatly reduce pipeline system shock and noise. And can fundamentally resolve pipe joints displacement, axial stretch and non-concentricity.
2. By using different materials, it can be made many kinds to cater for different medium and environment. Such as acid resistance, alkali resistance, corrosion resistance, oil resistance and heat resistance etc.
3. The material is pure rubber, sealing is very good. It is in light weight, very easy for installation . This product has long life performance, but must be not contact with sharp metal instruments to avoid piercing the sphere.
4. The product can be used for lift and transportation of raw water and sewage, transportation of water supply cooling cycle water thermal power ,condensate water of metallurgy industry and chemical industry,
