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?

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 193.

from was completely revised and the result was published in Select a picture to open the gallery 8 Pictures. Scientific Image of the Day: Such an in-line resonance was not considered in the original calculation basis from Our portfolio can be seen asme ptc 19.3 tw 2010.

It stands as the benchmark: This 199.3 of the standard only considered the more frequently occurring vibrations at right angles to the flow direction. The amendments contained within it relate to the following three aspects. Infos can be found under www.

News from process industries from all over the world. For the case, which cannot be completely eliminated, of a thermowell rupture resulting from in-line resonance, the standard demands asme ptc 19.3 tw 2010 provisions to prevent severe injury to personnel or damage to the plant. The revision provides some clearer and more-detailed definitions.

Dos Santos International; Picture: This applies, for example, to companies in the oil, gas and chemical industries. Ptv Klingenberg a. It was caused by the rupture of a thermowell due to turbulence: This standard remained unchanged for more than 20 years.


How to Select the Right Measuring Spot? 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. How this translates into figures is shown in the table see picture gallery.

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. Electrical Temperature Measurement Spoilt for Choice: This article is protected by copyright.
