Dear Friends
as i consult with our vendor, they will give us the performance guaranty so any future problem is on his response so i think mentioned test are not essential. as you know the test price (specially for max-min flow rates) are high and in previous project we didn't ask vendors to do...
in order of liquid distributors form internal suppliers such as SULZER,RASCHIG,... is it essential to ask liquid distributor test or not?
there are 2 type of tests: gravity test and max.min. flow rate tests.
which one is essential?
