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 analytically purposes. Anchors Bends Cuts Flexible Joints Frames Hangers Nozzles Pipes Reducers Rotating Equipment Supports Tees Valves Vessels
Note: AutoPIPE does calculate the element stiffness matrix of a bend differently from a straight pipe. The stiffness matrix was originally taken from SAP IV ( click here for technical manual ) which acted as the basis for AutoPIPE analysis engine. This is not the original SAP IV manual, and note that it acted only as a basis.
Item #0: Model branch connection on an elbow
Item #1: Model an Elbow with Tapered weld joint for Nuclear NB analysis
Item #2: Model a short, Long (1.5D), 3D, 5D, or custom radius Elbow
Item #3: Insert Valves, Reducers Or Other Components After Elbow Or After Tee
Item #4: When a flange or valve is modeled after an elbow, does it affect the stiffness of the elbow in the analysis? If so, how?
Item #5: Add multiple points on a bend
Item #6: Calculate the weight of a typical pipe fittings (i.e. Tee, elbow, reducer, etc..)
Item #7: Model a Pulled Bend and does the program consider the thinning wall on the outer radius of a pulled bend
Item #8: Model a 120 deg - 6 ft radius bend
Item #9: Analyze stress in non standard 45 or 90 degree turns
Item #10: Model a socket elbow, or other Socket welded fittings (i.e. Tee, valves, Sockolet, etc..)
Item #11: Specify user stress indices to apply to only one end of a bend
Item #12: What SIF is being used in the calculations: Automatic Code calculated SIF, User Defined SIF or other?
Item #13: Model a 3 degree mitered joint with 1 cut on the horizontal X-Y plane
Item #14: Model a S - bend that has bend angles less than 90 deg and is offset in the Side view
Item #15: Convert all node points along an entire pipe line of imported survey data into bend points
Item #16: Model large radius, back to back, bend piping
Item #17: Bend flexibility calculations
Item #18: Drip Pan Elbow
Item #19: Model Bend from 2 different directions
