Thermowell strength calculation
WebbWhen fw = fn, the thermowell goes into resonance, and vibrating forces increase rapidly. The resultant vibrations can cause mechanical failure of the well. The Murdock … WebbThe thermowell design has PASSED the wake frequency calculation “These well design calculations are based on the ASME power test code PTC 19.3- formulas. The results of these calculations should only be used as a guide for thermowell design.

thermowell materials information, calculate the natural and Strouhal Frequency, compare the ratio to 0.8, calculate the bending stress, compare maximum pressure to process pressure, and check the maximum length to the desired length. WebbThe selection and supply of thermowells may be a small part of the safety of a process plant but every small part has an impact; a plant is only as safe as its weakest part. There are three vital things that we must understand: – Thermowell stress calculation – Flange specifications – Material control and verification
