The long awaited PTC TW is a completely new standard that ASME responded to changing industry demands for a more comprehensive set of. thermowell failures in their systems, but ASME PTC had been the standard by which most thermowells were designed. Color enhanced smoke trail . Since then, ASME PTC TW has been applied successfully worldwide in all industries whose processes are subject to high loads.
