To avoid thermowell damage from mechanical loads, it is suggested performing a wake frequency calculation according to ASME PTC 19.3 TW-2016 standards for critical processes. If results are negative, solutions like shortening the thermowell stem or increasing root and tip diameters can be considered, though they may slow response time. Alternatively, a support collar stabilizes the thermowell stem within the flange nozzle but requires on-site machining. Tempotech’s Helical design reduces oscillation amplitude by over 90%, enabling quick, easy installation without a support collar, saving time and cost. .
