Thermowell design and selection

A principal stress model is proposed as a basis for selection in high-velocity or corrosive services

Specifying the pressure rating and use of corrosion resistant materials is usually sufficient to guarantee mechanical integrity of thermowells. However, in high-velocity fluids, a more comprehensive basis for selection is needed.         Fig. 1. Cantilever coordinates for the continuous beam model. Current velocity rating tables are usually based on a nominal steam or condensate service to serve as a guide for thermowell selection. Murdock's stress model (1959) and its companion, the ASME Performance Tes
