What Has Changed with the Revision of the ASME PTC TW Standard?
Click on our picture gallery to find out! As a result, passing through the in-line resonance is possible, if the process medium is gaseous and the range of the in-line resonance does not fall within the continuous operation of the plant.
Such an in-line resonance was not considered in the original calculation basis from News from process industries from all over the world. In there was a serious accident at the Japanese nuclear power plant in Monju. It was caused by the rupture of a thermowell due to turbulence: 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 stands as the benchmark: This edition of the standard only considered the more frequently occurring vibrations at right angles to the flow direction. Scientific Image of the Day: Main Germany Company Profile Contact. Within Asia, India aims to add a total capacity of approximately 8.

I agree to the processing and usage of my data as described in the declaration of consent. You want to use it for your own purpose? The revision provides some clearer and more-detailed definitions. This applies, for example, to companies in the oil, gas and chemical industries.
The vibration asmee of the tube was parallel to the flow direction of the medium in the pipe. As expected passing through this in-line resonance is the responsibility of the plant owner. The amendments contained within it relate to the following three aspects.
Chemical Safety Board; Picture: Here, pt permissible flexural fatigue stress must not be exceeded during the cumulative number of vibrations of 10 11 cycles. How this translates into figures is shown in the table see picture gallery.

The provisions that it contained for the wake frequency calculation were based on J. KG Klingenberg a. Our portfolio can be seen here. Receive 15 new engineering projects per week — get them easily delivered into your mailbox. This standard remained unchanged for more than 20 years.
Furthermore, the process medium must not adversely affect the fatigue strength of the thermowell material. This article is protected by copyright.
