Answer:

This is akin to modeling like FEA; insert a number of short run points and vary the temperature a small amount in each run of pipe.

Step #1: Build the piping system in AutoPIPE

Step #2: Determine what section of pipe is to have the thermal gradient

Step #3: Determine length of pipe run for each temperature change,

Example: pipe run is 10 feet,

what is the distance for each temperature, 1', 6", 3", 1", etc...

Regardless insert new run point along the existing run at the chosen increment

Step #4: Open the Press/Temp/Pipe ID tab on the input grids.

Step #5: For each pipe length vary the temperature the same increment along the length of pipe

Example: suppose the temperature changes from 100 to 205 long a length of pipe, the run point increments along the 10' length of pipe is 6 inches. the temperature change would be 5 deg f. along each run of pipe
