Atmospheric pressure reactor, outer half-pipe for heating – a question from a beginner

So is the design pressure of this reactor still at atmospheric pressure, without needing to consider the impact of the pressure of the heating medium on the reactor vessel? Is there anyone who understands mechanics who can explain this?
The effect of external pressure on the reactor vessel must be taken into account; it can be designed for normal pressure, but its strength must be checked based on the pressure required by the heating medium.
No need to be an expert in mechanics; it’s still considered a pressure vessel at normal pressure. The new regulatory standards explicitly state that this is not within the scope of pressure vessel regulation.
The outer coil acts as a jacket! The equipment’s inner container and outer coil are each designed according to their respective operating pressures! It’s still a atmospheric-pressure device! But the wall thickness of the inner container is determined by the design pressure of the outer coil!
Agree with what was said above; it is still a pressure vessel at normal pressure, but the effect of the pressure inside the coil must be taken into account when performing strength calculations
A pressure vessel at normal pressure is sufficient; if it is designed as a pressure vessel, many more qualification requirements apply
It remains a pressure vessel at normal pressure; only the effect of the pressure in the coil needs to be taken into account when performing strength calculations
For external half-pipe heating, it can be treated as a pressure vessel at normal pressure, and there is no need to conduct a review regarding external pressure.
It shouldn’t be necessary, right? At normal pressure
Well, we also need to use reactors with external coils; it’s a reaction at atmospheric pressure. If there are tubes connecting to the atmosphere, then it’s considered an atmospheric-pressure vessel. I think the vessel design involves checking both the internal and external pressures – those who understand vessel design know this~
