What is the difference between the theoretical weight and the actual weight of a heat exchanger? Generally, heat exchangers are purchased based on their weight – is the pricing based on the theoretical weight or the actual weight?

I haven’t been involved in procurement, but I know that some manufacturers quote prices for equipment by multiplying the theoretical weight by a certain coefficient; if the actual weight differs little from the theoretical weight (1%~3%?) ), should we go with the quoted price? Please, experienced sea travelers, share your thoughts! !

Well, generally manufacturers charge based on theoretical calculations; I’m not sure if that’s reasonable or not

Are they selling cabbages? It shows utter frustration. . . . . . .
