Did TEMA mention any situations in which expansion joints should be installed?
Thread Content
Question: 1. What does it mean to determine whether an expansion joint is needed based on TEMA, rather than saying it is determined based on ASME? Did TEMA mention any situations in which expansion joints should be installed? 2. The ASME standards state that heat exchangers need to be considered for various operating conditions such as normal operation, startup, and shutdown. Do the TEMA standards also require that heat exchanger design take different operating conditions into account?
It can be determined through FEA calculations to see if additional installation is necessary
The metal wall temperature is calculated using the heat exchanger, and the magnitude of thermal stress in the equipment is determined to decide whether an expansion joint is necessary； When designing a heat exchanger, various operating conditions such as startup, normal operation, and shutdown must be taken into account.
