    Flange bolted connection Analysis

    Hi All, I had a doubt about performing an FEA on an Flange bolted connection. The flanges are designed as per ASME B16.5. Line Size: 24in 900ANSI MOC: A182 F316L Stud and Nut: B7 & 2H Torque on stud: Stud is tensioned to 50ksi and the torque applied is 8782 ft lbs (I converted this...

    Weld joint as per ASME is failing (FEA Analysis) at working pressure when bolt preload is applied

    Hi, I'm new to FEA analysis. We design our valves considering wall thickness from B31.3 and the weld bevel dimensions as per B16.25. Our valves are not failing at hydrotest pressure (1.5 * working pressure) during actual testing. But while performing FEA on the valve the weld joint is showing...

    Stresses at the Bolt connections

    Hi, I want to calculate the stresses generated at the Bolt connections (between the flanges of the valve and the pipe) due the working pressure of the fluid in a valve. Is there a way by which we can avoid creating the flange of the pipeline and create a virtual wall to constrain the bolts...

    Stresses at the Bolt connections

    Hi, I want to calculate the stresses generated at the Bolt connections (between the flange of the valve and the pipe) due the internal pressure of the fluid in a valve. Is there a way by which we can avoid creating the flange of the pipeline and create a virtual wall to constrain the bolts? Thnx!

    Constraining a line to the edge of the model

    Hi, I'm unable to constrain a line to be colinier to the edge of a cylinder previously extruded even after trying the different filters. Even (in drafting enviornment) while inserting the base view the cylinder (side view --> circular end), entered the Active sketch mode and drew a cirlce. I...

    how to edit Arc length in drafting enviorment

    Hi, In drafting enviornment, once a line is drawn and dimensioned its length can be changed by double clicking and then entering the required length. But the same is not happening while drawing a arc. THanx

    Configuring dimensions in clone/child files

    Hi, Is there a way around to configure a certain parameter without calling it from the part family table. For e.g. if I created 4 part files(child parts) from 1 master model and I have 5 parameters being controlled from the part family table. Is there a way to control a 6th parameter without...

    Automatic updation of master & child file location

    Hi, Consider that a master model and 4 child/clone parts using part families. Now when we move these file locations say from local machine to server how can we make the address where the child parts created (Tools --> Part families)automatically update to whatever the master model location is...

    Problems in NX8.5

    Hi, I have been facing 3 problems while modeling in NX8.5 1. Lets consider I'm making a cube with the length, breadth and heigth and then controling them from the part families table. Now the issue is like if i edit these parameters from part families spreadsheet they get updated in the model...

    Unable to get Break out section in drafting

    Hi, I'm unable to get the break out section view in drafting. A dialog box appears while selecting the command which says that lightweight drawing views are not supported for break out sections. What should be the base point, even after selecting the extrusion vector it doesnt allow to select...
