Metal Bellows Expansion Joint for pipeline
The product can be used to eliminate the thermal expansion or displacement of pipelines, containers or equipment caused by climate change or other reasons. It can be installed at the inlet and outlet or at both ends of other high-frequency mechanical pumps to reduce or eliminate vibration and improve the service life and sealing performance of pipelines. It has the characteristics of reliable operation, compact structure, strong compensation ability, corrosion resistance to various media, long service life and so on.
Performance of metal bellows expansion joint
1. Corrosion resistance
2. High and low temperature resistance (- 196 ℃ to 420 ℃)
3. Light weight
4. Small volume
