1. Functionality: Expansion joints (bellows or compensators) are designed to handle axial, lateral, and angular movements, misalignment, and vibration within piping systems.
2. Customization: Standard joints come with three convolutions. More convolutions can be customized to provide greater movement. Optional reinforcements like rings and outer shells are available for high pressure or vacuum performance.
3. Safety Controls: Tie rods and hinges are utilized to limit maximum/minimum movements or prevent movement in specific planes.
4. Lining Options: High-quality lining materials include PTFE and PFA to resist corrosive media.
Note: For expansion joint sizes larger than DN300, a stainless steel housing type is recommended for enhanced vacuum resistance.
