Externally Pressurized Expansion Joints
Bellows Material: 304ss, 316ss, 321ss: Balance of Materials: Carbon Steel: Design Temperature: 400°C
- Externally pressurized expansion joints are used if there would be large axial movements.
- This type of expansion joint pressurizes the bellows externally, eliminating column instability concerns for the bellows.
- This configuration provides an outside cover protecting bellows from external elements and inside pipe acts as a liner protecting bellows from flow medium and and streamlines the flow.
