As you shared. . . . . The content related to the maintenance of shell-and-tube heat exchangers is still missing; I have gone through that section in the specifications countless times recently. . . . But today, everything was finally resolved. . . . . . Not satisfied, but it’s still acceptable

Just use the appropriate quota for that type of heat exchanger – what’s there that you can’t find? .
