Houston, TX USA — According to the pdf-downloadable Technical article on the Smart Sensors Inc. website, the major sources of thermowell failure for threaded or flanged bar stock thermowells are:
• Improper process application
• Improper material selection
• Improper installation
• Higher than anticipated temperatures
• Ignoring velocity considerations
Velocity considerations under high energy flow conditions cause vibrations, depending on the thermowell and flow properties.
Those conditions are discussed more on our Educational website where there is information on a free program to estimate the forces that can lead to severe thermowell damage under certain high energy flow conditions.
