Calculate wake frequency compliance yourself, quickly, accurately and independent of supplier constraints.

This application evaluates the wake frequency compliance in general accordance with the ASTM PTC 19.3 TW-2016 standard. 

The objective is to establish an assessment for the mechanical strength of the thermowell under forces caused by external pressure and the combination of static and dynamic forces resulting from fluid impingement.

This application is only applicable for tapered, straight and step-shanked thermowells, threaded, flanged or weld-in.
There are three material classes included : 316 SS, 304 SS and A105 CS. The application uses the latest ASME data to automatically calculate the mechanical properties of thermowells with these materials.
Based on the data provided, the application evaluates compliance against the standard and produces an assessment and a detailed report, which can be shared as a PDF file.

Click on the values in the DETAILS tab to adjust units.

This application is manufacturer independent, so can be used for any suppliers thermowells.
