Cost estimation can only come from the statistic database of market
prices accounting to fluctuation of market price. It cannot be arrive
by some technical thumb rules. Technical data can back the commercial
data not otherwise. By this I mean the range of interpretation is very
minimal due to various factors in the manufacturing process, regional
factors etc.
To qoute one of the factor, NPS 24 manuf. is not same as NPS 40 due to
plate config. limitations. Another important one is the testing. Many
other factors are there. However these two contribute a good portion
of the cost to derail any of your interpolated cost between such size
ranges.
Simple solution is to ask offers from few vendors with a blanket
requisition. Or a a phone call will do.
