01c. Model Non-metallic Plastic Piping (i.e. Plastic, PVC, PP, PPR, HDPE, PE, FRP, GRP, etc.)

Comments, Questions, and Answers

Notes:

1. Typical modeling approaches of plastic piping:

- See AutoPIPE Help Supplemental documentation, tutorial section: 1. ASME B311 With HDPE Tutorial and 2. ASME ND With HDPE Tutorial

- Learning Path - Non Metallic Piping Analysis in AutoPIPE

2. AutoPIPE V8i 09.05.01.xx and higher has a new Piping code: Iso14692 (Petroleum and Natural Gas Industries - Glass Reinforced Plastics (GRP) Piping). Note: that an document called "Tutorial - ISO 14692 FRP" is available in the in program help under "Supplemental Documentation" (for AutoPIPE V8i - folder location: "C:\Bentley\AutoPIPE V8i SELECTseries\Documents").
