New ScrutonWell ® design for thermowells
| Kai Grabenauer | TemperatureIn order to avoid any damage to the thermowell during operation due to mechanical loads, a thermowell 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 …
What does “adiabatic compression” mean and what is a pressure-surge test?
| Stefan Heusel | Know-howThe term adiabatic compression refers to an abrupt temperature increase as a consequence of a pressure surge. Such temperature increases occur in gaseous media, when the thermal energy which is released due to a change in pressure cannot be passed on to the environment …
