How to inspect the tube ends of a heat exchanger tube bundle?
Thread Content
As far as I know, it is inspected using pressing fixtures: the housing, the body tongue, and the pressing ring. This method allows for verification by requiring the creation of a set of tooling for each specification of heat exchanger. Do any experts have more advanced approaches?
If it is a production unit or a specialized repair unit, a general pressure vessel must be constructed, which can only be used for pressure testing to check for leaks. For reference.
For tasks such as heat exchanger maintenance that involve only the tube bundles, if a large number of such tasks are carried out each year, it may be worthwhile to develop a set of universal pressure testing fixtures.
The manufacturing cost for each size is too high, and there are several sets due to different pressure levels.
What does a generic one look like?
This term \"universal\" refers to coolers with the same type of core.
