There is no corelation between a cylinders ID to OD.
id means inside diameter, od means outside diameter, copper pipe and tubing is measured by the od, therefore the od the pipe or tubing will be the same as the id of the fitting
Can you calculate the ID of a pipe when you have the OD to be 10.75" and the wall thickness to be 0.5"Depends on what you know about it. If you have the outer diameter and you know the wall thickness, then ID = OD-2 x wall thickness
assuming it's hollow. 10.68*ID*(OD-ID)
To calculate the outer diameter (OD) of a cylindrical object when you have the inner diameter (ID) and the thickness of the material, you can use the formula: OD = ID + 2 × Thickness. This accounts for the thickness on both sides of the cylinder. Simply add twice the thickness to the inner diameter to get the outer diameter.
it will vary by Tool Joint OD and ID. FYI 7"OD x ID 4" HT55 is 52,600 Ft lbs

wall thickness of pipe is (OD - ID) /2
it means outside diameter as opposed to id which is internal diameter
CID. see http://historymedren.about.com/od/cwho/p/who_cid.htm
Inside diameter
