Flange thermowell ScrutonWell®

stainless steel

Optimised root design Easy and cost-effective installation Application in critical measuring points ScrutonWell® - Innovative design for the damping of vibrational excitation Applications Petrochemical industry, on/offshore, plant construction For highest process loads Application in critical measuring points Special features The damping of vibrational excitation by helical strakes is a recognised state of the art in a wide variety of industrial applications Easier and more cost-effective installation of the thermowell without any machining of the collar or nozzle compared to the conventional support of the thermowell with support collar Optimised root design for improved bending strength Description In order to avoid any damage to the thermowell during operation due to mechanical loads, a wake frequency calculation per ASME PTC 19.3 TW-2016 is recommended for critical process conditions. In case of a calculation with negative results, the only constructive solution so far was to shorten the thermowell stem or to increase the root and tip diameter, accepting a longer response time of the thermometer. The only other alternative up to now was to use a support collar to stabilise the thermowell stem inside the flange nozzle. This variant required an on-site machining of the collar to assure an interference fit in flange nozzles. The ScrutonWell® design reduces the amplitude of oscillation by more than 90 % 1) and allows an easy and fast installation of the thermowell without support collar, and thus without expensive and time-consuming rework on site.
