Angular expansion joints are expansion joints that absorb angular movements in a plane They are equipped with joints that allow only angular movements.
Advantages of angular expansion joints
- Medium to large expansion absorption possible
- Relatively low fixed point load
- Lower fixed point load than e.g. with axial expansion joints
- Regular guides are sufficient
- Pressure test possible even without fixed points
Disadvantages of angular expansion joints
- Tricky design
- Redirection of pipe work required
- Greater space requirements (than e.g. with axial expansion joints)
- Two or three expansion joints required for a compensation system
- Higher unit costs (than e.g. with axial expansion joints)
- No axial expansion possible
