Check or clean the access manhole that has been reserved

This isn’t a waste heat boiler, right? It’s some auxiliary equipment for a system, right? Deaerator? ? ? Or something else? ?

I’m not sure what ‘luo’ is meant to convey There’s nothing wrong with installing manholes.

This is the waste heat boiler, which is the conversion unit

I mean, why do both the tube side and the shell side need manholes? If the manholes on the shell side are there for ease of maintenance, then they’re filled with tube bundles – are they used to block the tubes?

Is it the pipe that’s leaking? Should I block it from the inside or what? Could you explain it in detail?

Used for inspecting the internal structure and conducting tests

It can be used to inspect the weld joints between the tube sheet and the heat exchange tubes. Additionally, check whether the shell side is lined; if it is lined, it can be used during the lining installation.
