[Video Introduction] ASME PTC 19.3 Strength Calculation Method for Protective Tubes
WIKA Scruton-type protective tube
The American standard ASME PTC 19.3 TW-2016 is the most important international standard for protective tubes. This video explains it in an easy-to-understand manner.
▬ Content of this video ▬▬▬▬▬▬▬▬▬▬▬▬ 0:00 Intro 0:10 The impact of vortex shedding on the protective tube 0:23 Strength calculations according to ASME PTC 19.3 TW-2016 0:38 Calculation results that failed and alternative versions of the protective tube 1:07 Limitations of conventional protective tube designs 1:19 Protective tube design of ScrutonWell 1:36 Installation and usage of the protective tube in ScrutonWell design What are the strength calculations for protective tubes? What designs are available for protective tubes? Which design is optimal for my application? These questions are very important because protective tubes play a crucial role: - Protection of temperature measuring instruments - Protection of human beings and the environment - Cleaning and replacement of temperature measuring instruments during operation In general, protective tubes have a very long lifespan. However, they can vibrate under vortex shedding or hazardous conditions. In extreme cases, this can lead to damage to the protective tube.

basic information
Strength calculations can solve this problem and have become an essential element in the design of various plants. The American standard ASME PTC 19.3 TW-2016 is currently the most important international standard for protective tubes. You can check the program for measuring the dimensions of protective tubes here: https://bit.ly/3KWSjpR. In approximately 30% of cases, the results of strength calculations fail. To pass the strength calculations, it is necessary to modify the design of the protective tube. In this case, the results of the strength calculations for the protective tube can be optimized using four methods: - Shorten the insertion length at the connection. - Increase the diameter at the base or tip of the stem. - Change the nozzle dimensions. - Shorten the insertion length. For more details, please refer to the technical information below: https://bit.ly/34po1LX. Scruton Design's protective tubes have many successful implementations as an alternative. The helical structure can effectively suppress vibrations caused by Kármán vortices and is used in a wide range of industrial applications. The ScrutonWell designed protective tubes are easy to install, just like conventional designs.
