Dennis HawParticipantCan anybody help with a method by which we can convert inch-diameter into a weight and lengths mto calculator (spreadsheet)?

Mark LayportMemberSo are you the purchasing guy and are trying to estimate shipping cost? …Well if your really interested in getting “weights” then I suggest getting a piping book called “Navco Piping Datalog Book” …Pittsburg, PA., USA …they have just about every type of piping and with weight factors, so you can calculate the weights you’re looking for.

Dennis HawMemberNo, I’m the Piping Designer on the job tasked with coming up with a conversion calculator / spreadsheet to convert inch-diameters to lengths of pipe, which in turn can be converted into weights.
Perhaps my question should be how to convert inch-diameters into inch-meters, which can then be converted back to lengths, from which I can calculate weights? -

Anton DooleyAdministratorAshtray,
I think this may be what you are looking for: Principal properties of commercially available pipe
You can find it here:
http://pipingdesigners.com/contents/tips-tools-training/section-11-piping-layout/88-section-11b-pipe-piping-tools-downloads.html(2nd from bottom on the list)
It has an imperial and a metric tab, and lists Pipe Wt. per kg/m or per ft [lb] among other things.

Mark LayportMemberWell then I don’t understand WHY you want to know what pipe weighs!?? Every MTO I have generated the pipe is indicated by size, schedule, material (carbon steel or what ever), and listed as a quantity in linear feet (so suppliers can change that value to “radium or double radium lengths”) …The weight of the pipe was/is not required. You can prove this to yourself by calling a supplier and ask for 1.75 tons of 10″ pipe …see what they tell you!??
However, “IF” you feel you still need “something” to generate a weight, then I would suggest you contact the structural group that deals with pipe supports, they have to calculate pipe weights for supports, OR maybe a manufacture and see if they have something to get the info your looking for, they would be interested in “weights”. …Good Luck! -

Dennis HawMemberThanks Anton but no, that’s not what I’m after.

The way you have defined your task is confusing to me. I remember the term “inch-diameter” was normally used when calculating the amount of Field welding required on a project. I have never used it myself (or seen it used) in the context used in relation of lineal feet (or meters) of pipe and/or weight of pipe.Based on your profile you are not a novice so I am puzzled by the subject. Can you shed any more light on the assignment you have been given?

Dennis HawMemberThat’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?
