Applies To Product(s): AutoPIPE Nozzle, Version(s): V8i Environment: N/A Area: Modeling Subarea: Original Author: Bentley Technical Support Group Comment, Questions, and Answers: Item #1: Does AutoPIPE Nozzle have metric and English units? how to change? Answer: Yes, AutoPIPE Nozzle has 5 different unit libraries: select the System Tab, Units system from the drop-down list. Library units are: English (default) , Kip_in, metric, mmetric and SI Customized units file can be created by copying / rename an existing units file e.g. English.UNN then editing using an ASCII editor. Item #2: What code should I select WRC-107, WRC297, WRC-537? Answer: Due to liability lawsuits Bentley can not provide design details such as this. Recommend to review both codes and determine which is more applicable to your project. Only comment is a quote from WRC-297: WRC Bulletin 107, "Local Stresses in Spherical and Cylindrical Shells Due to External Loadings," by K. R. Wichman, A. G. Hopper, and J. L. Mershon, has been widely used by design analysts since its initial publication in August 1965. ........ The persistence of this need was a major motivating factor for preparation of this "Supplement" provided here in Bulletin 297 that broadens the coverage of Bulletin 107 . WRC Code limitations: WRC107 WRC297 d/D <= 0.33 (1) d/D <= 0.5 D/T <= 600 20 <= D/T <= 2500 Where d - outside dia. of the nozzle D - outside dia. of the shell T - shell wall thickness Approximate limit of WRC107 for spherical shells is d /D = 0.33 (1) - Subsequent revisions have conservatively extended d/D <= 0.5 (but man be inaccuracies) See Also Bentley AutoPIPE External Links Bentley Technical Support KnowledgeBase Bentley LEARN Server Comments or Corrections?
