Applies To Product(s): AutoPIPE, Version(s): 2004, XM, & V8i Environment: N/A Area: Error Subarea: Original Author: Bentley Technical Support Group Problem: When modeling in AutoPIPE the following is displayed: --------------------------- Error --------------------------- E737-26: Valve components are not permitted in HDPE pipe system as per CC N-755-1. --------------------------- OK --------------------------- Why and how to get around it? Answer: Per N-755 code: -3100 SCOPE The design rules of this Section are limited to buried, polyethylene piping systems constructed of straight pipe, three and five-joint mitered elbows, fusion joints, and flanged connections. Therefore, so long as the pipe property being used has "HDPE Material" check-box checked ON. inserting a valve, tees, and other components not listed above are in direct violation of this code. Only solution is to enter a different pipe property that has "HDPE Material" option checked OFF or option does nto appear on the dialog. As an option, create a new pipe property using Material = NS (Non-standard), enter all relevant information like Density, Long, Hoop and Shear modulus. For modeling, as AutoPIPE does not have the correct SIF values insert user SIF for all joints to override the default SIF values. In addition, enter user Allowable values as per HDPE pipe.
