Problem:
In B31.4, Table 403.3.1.1, no stress is mandatory for slurry lines except Pressure stress. How it is taken care for slurry line in b31.4 and AutoPIPE?
Answer:
At the moment AutoPIPE does not perform any such distinction for slurry lines. A new enhancement has been logged, TFS-E293329: Add slurry designation for B31.4.
Workaround:
In the meantime, as a workaround, correct allowable value for slurry piping for Hoop stress is given below:
Hoop stress allowable for restrained/unrestrained pipelines = 0.72*E*Sy
Hoop stress allowable for slurry pipelines = 0.80*E*Sy
a. Users can multiply the model's E factor value in the Tools> Model Options> Result with 1.11 (0.80/0.72 = 1.111) to get the correct Hoop allowable value for slurry piping.
b. Users may ignore the rest of the stress categories. Under Tools> Combinations, disable / uncheck Code Combinations that the user interprets as not required by the code.
