Does a plate heat exchanger fall under pressure vessels?
It falls under pressure vessels, but is not necessarily regulated by relevant standards.
It does not belong to pressure vessels; it depends on the operating conditions.
It does not fall under the category of pressure vessels; pressure vessels must meet all three requirements specified in the regulations for pressure vessels
For fully welded plate heat exchangers, which are considered pressure vessels, they fall under the regulations governing pressure vessels.
It should belong. According to the PED’s perspective.
Welding is not a requirement for pressure vessels； For example, it is said that early boilers were riveted.
It depends on the operating conditions for pressure vessels; the relevant regulations state this clearly, so it’s not possible to determine whether it is a pressure vessel or not
The regulations vary from ** to region; in China, detachable types are not considered pressure vessels, while fully welded types are considered pressure vessels
