12 Jul JMS Southeast participated in the ASME PTC TW commit- tee performing the first major revision since to the only US thermowell. standard, known as ASME PTC TW (“TW” for thermowell), is over 40 pages due to the explanations of theory and the sheer complexity of the process. ASME PTC TW was written to replace ASME PTC following some catastrophic failures in non-steam service, these thermowells passed the.

What Has Changed with the 2016 Revision of the ASME PTC 19.3 TW Standard?
Our portfolio can be seen here. This standard remained unchanged for more than 20 years.
asme ptc 19.3 tw 2010 Such an in-line resonance was not considered in the original calculation basis from Subscribe to the newsletter. It was caused by the rupture of a thermowell due to turbulence: 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. As expected passing through this in-line resonance is the responsibility of the plant owner. KG Klingenberg a.

What Has Changed with the Revision of the ASME PTC TW Standard?
You want to use it for your own purpose? How to Prevent Product Piracy. The vibration direction of the tube was parallel to the flow direction of the medium in the pipe. Here, the permissible flexural fatigue stress must not be exceeded during the cumulative number of vibrations of 10 11 cycles.
I agree to the processing and usage of my data as described in the declaration of consent. As a consequence of the Monju incident, the ASME standard from asme ptc 19.3 tw 2010 completely revised and the result was published in In there was a serious accident at the Japanese nuclear power plant in Monju.
Electrical Temperature Measurement 210 for Choice: Wsme 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. Dos Santos International; Picture: It stands as the benchmark: Scientific Image of the Day: News from process industries from all over the world.
The revision provides some clearer and more-detailed definitions. This article is protected by copyright.

Furthermore, the process medium must not adversely affect the fatigue strength of the thermowell material. The amendments contained within it relate asme ptc 19.3 tw 2010 hw following three aspects. 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.
