Problem:
How to correctly model a reducer mounted to the branch of a Welded Tee in AutoPIPE?
Solution:
Suggest using one of the following 3 methods:
step #1: Starting from the branch of a Tee node point:
Note: header pipe is 12" dia OD
option #1:
Step #2. Insert run to weld location between Tee and Reducer:
From Catalog, 12" welded tee, branch length = Dimension "N" = 10.00"
Step #3: Insert Reducer
Step #4: Insert smaller pipe run to next location
Done!!!
Option #2:
Step #2: Insert pipe from Tee Node point to outside surface of header pipe
Step #3: Insert pipe from surface to weld location of reducer
Step #4: Insert reducer
Step #5: Insert smaller pipe run to next location
Step #6: Select the pipe from Tee Node point to outside surface of header pipe (i.e. Step #2), Insert "Rigid Options Over Range", uncheck "Include Weight" option only
Done!!!
Option #3:
Starting with the following piping arrangement, notice that distance between node points is the exact distance for a reducer (ex. see reducer dimensions above P = 8")
DO NOT select run between existing node points or inserting a reducer who's length is the exact same distance between 2 node point. This is not good modeling practice. One cannot just convert a pipe run to a component at this time.
Instead, Delete downstream node point (ex. B02). Then use Insert> Reducer> Length = 8"
One may need to select the piping on the reducer's small side and "Modify> Pipe Properties Over Range" to select the correct pipe size.
