CAESAR II Version

Specifies a single unrestrained expansion joint. This type of joint can absorb movement in all directions. It also subjects the system to pressure thrust which must be designed for, external to the expansion joint. This type of joint should almost never be used by the expansion joint novice needing to protect hot, pressurized equipment. The conditions below make using and analyzing an untied expansion joint difficult:

  • Guide restrictions limiting displacements into the joint

  • Regular maintenance problems because of support hardware away from the bellows

  • Pressure thrust
