That’s correct Jop, that’s my understanding too. But my task is as follows;
MTO Procedures – Inch Diameter basis to weight and length’s MTO calculator:
Requirement is to have a tool that can perform calculations from one format (inch diameter) to MTO data and a vice versa. Areas in calc. to include all piping items, fittings, flanges, etc. to match with the mating edges of uneven / different thickness wherever required, threading connecting with equipment nozzles, fixing of gaskets, bolts, nuts, elbows, reducers, tees, vents, drains, valves, weld inches.
No mean task, eh?
I thought about using inch-metres, used for estimating erection costs, and finding a way of converting to inch-diameters. But inch-metres requires known lengths of pipe. My task, I think, is to derive a conversion factor from inch-diameters to lengths and weights where the unknown factors, diameter and length, can be inserted later depending on the project requirements we’re trying to estimate costs for.
I hope this makes more sense and the problem more resolvable?
