Guys, I have a quesion about the levels of discoloration in ASME BPE CODE, bioprocess equipments (Fig. MJ-8.4-2 and Fig. MJ-8.4-3 - BPE-2016).
How do I choose the appropriate maximum discoloration level of welding for my fluid?
Is there any table or pattern, like:
Hot Water = Levels #3 to #4;
Perfum = Levels #1b to #2;
Vaccine = Level #1a.
Because, the standard always says: "The maximum level of discolorayion must be choose by the employer".... ok, but, how does the employer choose then?
Do I need to have many tests with each tube to tube and fluid one by one?
