Vibration calculation of temperature sleeves
Thread Content
Under some complex operating conditions, it is necessary to conduct vibration calculations on the thermometer’s casing in order to prevent accidents caused by the casing breaking during use. What experience do you all have in this regard? For example, under what conditions are such calculations required, how are they carried out, and what standards are used as a basis?
There’s no need, right? The casing itself already has a certain thickness, and I’ve never seen the casing break due to vibration.
There have been cases of temperature sleeve failure in refining units, especially in catalytic units where the flow rate of the medium is very high.
Due to vibration, our company has encountered cases where the thermometer sleeve caused the flange on top of the reactor to break completely – it’s quite serious, so caution is needed. We are now using Kai-style designs, which reduce vibration; moreover, the casing itself can be strengthened by making it thicker.
Put a protective tube over the thermometer sleeve (note: it is not placed at the temperature measurement point)
