outside to outside
In pipe sizing, nominal bore (NB) is used to indicate the approximate internal diameter of a pipe, while the outside diameter (OD) is the actual measurement across the pipe's exterior. For pipes sized 14 inches and above, the NB is equivalent to the OD because these larger pipes are often constructed to a standard where the wall thickness is relatively uniform, making the internal and external measurements more closely aligned. This simplification helps in standardizing pipe sizes for ease of specification and installation in larger applications.
(Pi*(Center of elbow - od/2)^2-(pi*(Center of elbow+od/2)^2)÷4)÷100000=0.221 Square Meter
measure the length of the fitting first. Then insert pipe into fitting and mark a line on pipe. measure that bit of pipe. deduct off the length of fitting and half it to give you your x dimension
The width of a circle such as a cross view of a pipe.
to divide a pipe into sections measure the outside diameter then multiply by 3.142 this will give you the circumference divide this number by how many sections you require place a mark anywhere on the on the pipe then measure from that mark your answer The best method for calculating the cross section area of a round pipe or tube is to use the following formula: ((D-W)*W)*PI Where as D= Outside Diameter Measurement W= Wall Thickness PI= 3.1416 that is circumference. The answer I have is: diameter squared x .7854 Ex. 3inch pipe (inside diameter) 3 x 3 x .7854= 7.0686
To find the outer diameter (OD) of a pipe ranging from 1 to 10 inches, you can refer to standard pipe size charts, which specify the OD for different nominal pipe sizes. For instance, a 1-inch nominal pipe typically has an OD of 1.315 inches, while a 10-inch nominal pipe has an OD of 10.750 inches. Additionally, you can measure the pipe directly using a caliper or tape measure if you have access to the physical pipe.
pipe is measured up 12 inchs I.D. inside 12 and above are measured by O.D.if you measure 10" pipe you measure it from inside..12" and above measure from outside diametor
Measure the outside diameter of a pipe with some calipers. If you don't have these then you can get a good idea by using a ruler or tape measure, making sure to go through the mid point. It's outside wall to outside wall.

OD is Outside Diameter - at least when you are talking about pipe...
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
14" and above
89mm
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
NB = inside diameter of the tube. OD = outside diameter of the tube.
The outside diameter (OD) of a 40-inch nominal bore black steel pipe is typically 40 inches, as the nominal size refers to the approximate internal diameter of the pipe. However, the actual OD for standard pipe sizes can vary; for a 40-inch nominal bore, the standard OD is approximately 42.16 inches according to the American National Standards Institute (ANSI) specifications. This discrepancy is due to the wall thickness of the pipe, which is accounted for in the nominal size.
