Endress+Hauser introduces a free on-line thermowell calculation tool to help customers stay compliant with the new ASME PTC 19.3 TW-2010thermowell standards. The thermowell sizing toolcalculates the thermowell’s ability to withstand stresses under given process conditions, important for safety-critical or demanding applications with high flow rates or high process pressures, particularly in the oil and gas and chemical industry.Because a thermowell is subjected to a variety of stresses in these types of applications, typically because of in-line and transverse vibrations, it is necessary to run calculations on the thermowell design to make sure these stresses do not exceed the maximum allowable limit. Endress+Hauser’s thermowell sizing calculator gives users a safe alternative to not only thermowell failure but loss of measurement, damage to expensive equipment, and safety risks to plant personnel. Unlike the traditional, time-consuming approach of using spreadsheets, the thermowell sizing calculator allows usersto make preliminary calculations to select the right thermowell early on in the design process – in just a few clicks. Enrichments in the thermowell calculation tool include a larger variety of thermowell geometries, such as stepped thermowells, and the updated ASME PTC 19.3 TW-2010standards have enhanced resonant frequency calculations allowing the maximum thermowell length to be determinedbased upon the process conditions.The thermowell calculation tool is available on-linevia the Endress+Hauser Applicatortool, a program that provides step-by-step assistance with product selection, sizing, and configuration.Also available on-line is a new white paper titled, “Basics of Thermowell Design and Selection,” that discusses thermowell design considerations, how to perform thermowell calculations, and options for selecting the right thermowell.
