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.
