Politeknik-Klinger / Products / Metal Expansion Joints / 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.
