May I ask, are there any specific standard requirements regarding the cleanliness of each sealing surface for the heat exchangers that are to be reinstalled after major repairs? Is a sealing surface necessary?

Clean it thoroughly; the seal grooves should also be cleaned clean, and it’s best to polish the sealing surfaces with a sanding machine

At least remove debris and rust, and check whether there are any defects on the sealing surfaces
