Is the heat exchanger a pressure vessel
I've never been a pressure vessel before, but this year's meeting has added heat exchanger to the pressure vessel. I've been tired of this rule recently
Depends on the definition of the pressure vessel.
A pressure vessel is an airtight device that is a gas or liquid that carries a certain amount of pressure. Storage containers, reaction containers, heat exchange containers and separating containers are pressure vessels. Not all of the pressure vessel to accept technical supervision departments of supervision and inspection, only in the related safety technical supervision regulations within the scope of the pressure vessel, such as the fixed rules ", "pan rules" and so on, to accept the supervision and inspection by technical supervision departments, and divided the corresponding category.
Both the tube and the shell of the heat exchanger are likely to be pressure vessels, as long as they are required to meet the requirements.
