How To Measure Pipe Thickness. Measure the pipe (female thread) measure the inside diameter (id) of the pipe and follow the same steps given above. The utg allows the user to find the wall thickness of the pipe when programming an ultrasonic transmitter without cutting or removing a section of the pipe to measure it.
The pipe shown in fig. Divide the total pipe wall thickness by two. As a result of calculation, they appeared continuous and symmetrical around the center of pipe.
Mark the point where the string touches together;
Wrap a string around the pipe; Spread the ruler across the diameter of the pipe and measure. A new general equation for determination of wall thickness from measured film density profile in a radiograph was derived. This is from the inside wall across to the other inside wall.
