Power Test Code Thermometer Wells

Abstract

Design of thermometer wells involves strength and thermal considerations. Criteria for thermal evaluation have been well established, those for strength have not. This paper presents thermometer-well designs proposed for Power Test Code work. Forces imposed by static pressure, steady-state fluid impingement, vibration induced by Karman trail vortexes, and structure-borne vibration are discussed. Methods and equations are given to enable the selection of wells for given service conditions. Although these methods are confined to wells of Power Test Code design, the Appendix contains derivations of general equations that may be adapted for any cantilever-type thermometer well.
