Obtaining Pipe ID
If you do not know the pipe ID, try to get pipe OD using one of the
following methods:
●
Read the pipe OD and schedule on the pipe.
●
Read the OD and schedule from system drawings.
●
Use a tape measure to measure the pipe circumference and divide the
measured circumference by 3.14.
●
Use Thermo’s Ultrasonic pipe Thickness Gauge (P/N 0704/0187), and
perform the following calculation:
Pipe ID = Pipe OD – (2 x Pipe Thickness)
