How are thermowells calculated | Wake frequency calculation per ASME PTC 19.3 TW-2016

How are thermowell calculations made? Which designs are available for thermowells? Which design is best suited to my application? How is wake frequency calculation used to optimise thermowell design? These are important questions, since thermowells perform very important tasks: 🛡️ Protection of the temperature sensors 👷 Protection of personnel and environment ✅ Cleaning and replacement of the temperature probes during running operation #WIKAgroup #WIKAsmartinsensing #Thermowell #WakeFrequencyCalculation #ThermowellCalculation #DimensioningThermowell ▬ Contents of this video ▬▬▬▬▬▬▬▬▬▬▬▬ 0:00 Intro 0:10 Effect of the Kármán vortex street on thermowells 0:23 Wake frequency calculations per ASME PTC 19.3 TW-2016 0:38 Negative calculation results and alternative thermowell versions 1:07 Restrictions of traditional thermowell designs 1:19 Thermowells in ScrutonWell® design 1:36 Installation and use of thermowells in ScrutonWell® design As a rule, thermowells are very long-lasting. However, due to the Kármán vortex street and under critical conditions, they can oscillate. In extreme cases, this can lead to the thermowell breaking off. The wake frequency calculation can solve this problem and is generally an integral part of the design of any industrial plant. The American ASME PTC 19.3 TW-2016 standard is currently the most important valid standard worldwide for thermowells. 📖 You can find further information in our technical information: Wake frequency calculation per ASME PTC 19.3 TW-2016 👉 https://wika.link/mqdn 💾 You can request a program for dimensioning your thermowell here: https://wika.link/8kas In about one third of the cases, a negative result may occur in the calculation. In this case, the design of the thermowell must be changed in order to obtain a positive calculation result. This can be done by optimising the strength of the thermowell in two ways: ✅ Shortening of the insertion length below the process connection ✅ Increasing the root or tip diameter of the stem However, various parameters can limit the optimisation process, such as: 📌 Nozzle dimensions 📌 Minimum insertion lengths 📖 Learn more in our technical information: Design of thermowells in special lengths https://wika.link/ajut Thermowells in ScrutonWell® design are a good alternative, and also for many other cases. The helical design, which is used in a wide range of industrial applications, effectively suppresses vortex induced vibration. Thermowells in ScrutonWell® design are just as easy to install as their counterparts with conventional design. 👇 Download our data sheet “Thermowell in ScrutonWell® design”: https://wika.link/avuq 🔗 Our team of WIKA experts will help you select the right thermowell for your application and take care of the complicated calculation for your measuring location: https://wika.link/mhtb ▶ Watch our other videos about thermowells: What is a thermowell?    • Thermowell: Definition and application   WIKA ScrutonWell® design for thermowells    • WIKA ScrutonWell® design for thermowells: ...   _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Follow us on our social media channels: 📺 YouTube:    / wikagroup   🎯 LinkedIn:   / wikagroup
