How to calculate heat loss for Schedule 40 pipe?
A steel pipeline, 2 in schedule 40 pipe, containing saturated steam at 121.1 C. The line is covered with 25.4 mm of insulation. Assuming that the inside surface temperature of the metal wall is at 121.1 C and the outer surface of insulation is at 26.7 C, calculate the heat loss for 30.5m of pipe.
How does the schedule number on a pipe relate to the thickness?
The schedule number on pipe products relates to the thickness of the wall on the pipe: as the number increases, the thicker the wall thickness becomes. Also, while the schedule number can be the same on different sized pipes, the actual wall thickness will be different. Here are a few examples:

What are the different schedules for a pipe?
There are several schedule numbers used on pipe, such as schedules: 5, 5S, 10, 20, 30, 40, 60, 80, 100, 120, 140, 160, STD, XS and XXS. The most common ones used are schedules 40 and 80
What is the thickness of a Schedule 40 pipe?
Pipe size 1.000” Schedule 40 – The actual wall thickness is 0.133”. Pipe size 2.000” Schedule 40 – The actual wall thickness is 0.145”. Pipe size 1.000” Schedule 80 – The actual wall thickness is 0.179”. Pipe size 2.000” Schedule 80 – The actual wall thickness is 0.218”.
Is the schedule number the same as the wall thickness?
Also, while the schedule number can be the same on different sized pipes, the actual wall thickness will be different. Here are a few examples: Pipe size 1.000” Schedule 40 – The actual wall thickness is 0.133” Pipe size 2.000” Schedule 40 – The actual wall thickness is 0.145”
What’s the difference between schedule 40 and Schedule 80?
Pipe size 2.000” Schedule 40 – The actual wall thickness is 0.145” Pipe size 1.000” Schedule 80 – The actual wall thickness is 0.179” Pipe size 2.000” Schedule 80 – The actual wall thickness is 0.218” What we can see here is that the schedule number increases the wall size, and that the wall thickness changes based on the nominal pipe size (NPS).
What do the schedule numbers on a pipe mean?
NPS OD Schedule # Wall Thickness ID. 1.000” 1.315” SCH 40 0.133” 1.049” (approx.) 1.000” 1.315” SCH 80 0.179” 0.957” (approx.) All pipes are specified using the NPS and schedule numbers. It is the schedule number that determines the approximate inside diameter.
