Metal Bellows Expansion Joint with Flange End
| Feature: | |||||||
| 1. To Absorb large axial displacement between straight tube and support frame , and small horizontal displacement; | |||||||
| 2. To resolve minor deviation because of piping connection and eliminate the pipeline residual stress; | |||||||
| 3. Easy cleaning and maintenance. | |||||||
| Applications: For the chemical industry, metallurgy, electricity, shipbuilding, construction and other industries. | |||||||
| Application temperature:-50 ºC~300ºC. |
