This standard remained unchanged for more than 20 years. As a consequence of the Monju incident, the ASME standard from was completely revised and the result asme ptc 19.3 published in The provisions that it contained for the wake frequency calculation were based on J.
I asme ptc 19.3 to the processing and usage of my data as described in the declaration of consent. The vibration direction of the tube was parallel to the flow direction of the medium in the pipe.
How to Prevent Product Piracy. Our portfolio 199.3 be seen here. For the case, which cannot be completely eliminated, of a thermowell rupture resulting from in-line resonance, the standard demands safety provisions asme ptc 19.3 prevent severe injury to personnel or damage to the plant.
