As a consequence of the Monju incident, hw ASME standard from was completely revised and the result was published in Here, the permissible flexural fatigue stress must not be exceeded during the cumulative number of vibrations of 10 11 cycles.

What Has Changed with the Revision of the ASME PTC TW Standard?
For the case, which cannot be completely eliminated, of a thermowell rupture resulting from in-line resonance, the standard demands safety provisions to prevent severe injury to personnel or damage to the plant. It was caused by the rupture of a thermowell due to turbulence: Chemical Safety Board; Picture: The amendments contained within it relate to the following three aspects.
The revision provides some clearer and more-detailed definitions. Our portfolio can be seen here.
What Has Changed with the 2016 Revision of the ASME PTC 19.3 TW Standard?
It stands as the benchmark: Dos Santos International; Picture: Scientific Image of the Day: Such an in-line resonance was not considered in the original calculation basis from This applies, for example, to companies in the oil, gas and chemical industries.
This edition of the standard only considered the more frequently occurring vibrations at right angles to the flow direction. In there was a serious accident at the Japanese nuclear power plant in Monju.

As expected passing through this in-line resonance is the responsibility of the plant owner. Once completed, the project is expected to be the biggest Pom manufacturing plant across the globe. The vibration direction of the tube was parallel to the flow direction of the medium in the pipe.
I agree to the processing and usage of my data as described in the declaration of consent. KG Klingenberg a. Furthermore, the process medium must not adversely affect the fatigue strength of the thermowell material. Select a picture to open the gallery 8 Pictures. Subscribe to the newsletter.
