Comments, Questions, and Answers about modeling non-metalic plastic piping (i.e. Plastic, PVC, PP, PPR, HDPE, PE, FRP, GRP, etc.) using AutoPIPE
Item#1:
See the following file for typical modeling plastic piping modeling approaches - download attached file
Note: AutoPIPE V8i 09.05.01.xx and higer has a new Piping code: Iso14692 (Petroleum and Natural Gas Industries - Glass Reinforced Plastics (GRP) Piping).
Item #2:
Why is it not possible to use elbows with HDPE pipe as with steel pipe? (Note from AutoPIPE Help: "For HDPE pipes, only Close and Wide are accepted options.")
Answer: At this time, AutoPIPE has only provided HDPE for B31.1 and ASME NC/ND and that uses the CC-N755-1 provisions. CC-N755-1 only permits miter bends for HDPE and provides B1 & B2 indices for miter and close bends only.
Otherwise, you would need to have stress indices for your HDPE bends that could be manually entered.
tem #3.
Is it possible to calculate HDPE pipe using any other (non-nuclear) code than N-755-1?
Answer: yes it would be posible, define Non Standard (NS) Pipe, with the correct values of allowable, modulus and everything required for calculations
