j. Valves Piping Components - Modeling Approaches, Tips, Techniques used in AutoPIPE

Attention: Please see the following AutoPIPE help section:

Help > Contents> Contents Tab> Modeling Approaches> Modeling Approaches>

This help has been provided in order to give users ideas for modeling typical piping arrangements. The steps shown in each example should not be taken as the only method available to create models. In addition, the intent of the examples is to present ways to create adequate models of specific piping components for analytic purposes.

Notes:

1. AutoPIPE does apply thermal expansion coefficients to VALVE components. The corresponding Temperature load case, (ex. T1, ..Tn) and expansion parameters on the Press/Temp/PipeID input grids are used to determine how much expansion will occur.

Comments, Questions, and Answers:

Item #0: Specific valve was missing from catalog, how to model valve?

Item #1: Model a 3-way valve

Item #2: Why does valve's Pressure Rating drop-down list only NS (Non-Standard)?

Item #3: Model a complex valve such as a Bell & Gossett Triple Duty Valve

Item #4: Model an Angle valve (90 deg valve)

Item #5: Model a pressure relief valve

Item #6: Why is wrong weight used when inserting a valve?

When inserting a valve with flanged end connections on both side, the wrong weight is automatically applied to the flanges. example: add a GateF Class 300 valve and tick the insert flanges option the flanges by default are the same weight as the valve.

Answer:

This is a known issue and has been logged under CAE-TR-10614 Using insert flange on both ends copies the weight of valve to flange and was fixed in AutoPIPE V8i 09.06.00.07 and higher.

Item #7: Model a Fire hose valve

Item #8: Model Valve + actuator based on catalog info with combined values
