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. .

Application Note

TWS-H Helical Threaded Thermowell is engineered for protecting temperature sensors in demanding industrial environments. It is specifically designed for use in petrochemical industries, onshore and offshore operations, and plant construction where high performance and durability are essential.

The helical threaded design enhances strength and resistance against vibration, high flow velocity, and mechanical stress. This ensures reliable performance under extreme conditions while maintaining accurate temperature measurement. It effectively isolates the sensor from aggressive media, high pressure, and rapid flow rates, extending sensor life and improving operational safety.

Built for harsh process environments, the TWS-H thermowell provides a dependable solution for critical temperature monitoring applications.
