Hi,
I am searching for right approach to model a section of piping, where the section modulus of commercial steel pipe has been increased (to allow greater span) by welding a T-section to the pipe. How do I create a Pipe Identifier, by modifying a standard pipe property where all other parameters remain unchanged, just the section modulus & pipe weight need to be updated. Can anybody provide guidance please? thanks in advance

Hello Sanjay,
One solution would be to model the pipe with its properties. Then model a Tee beam section correctly located against the pipe as shown below.
At multiple locations long the run of pipe and tee beam sections insert a connection between the two using a Rigid Beam or Connected Anchor component (weight of component = 0.00). You will have to determine the correct spacing of the connections to closely approximate a continuous connection.
You would also need to establish node points and respective beam points before inserting the connection component.
Again this is an approximation assembly.

Could you possibly post a step by step tutorial on how to model the beam on the pipe?
Can I just model a beam with the same coordinates as the pipe nodes with a y-coordinate equal to the half outer diameter of the pipe?
Good day to you Darja,
see steps below:
1. Model Pipe with numerous node points along the length
2. Model Steel beam relative to the pipe with corresponding node point lengths to that of the pipe
3. Connect the Pipe to the beam using Rigid Beam or Connected Anchor component as needed at various points along the pipe/beam. Confirm that this component has rigid properties and weight = 0.00.
Done.
It all depends on your vertical axis name and pipe orientation.
If AutoPIPE's model "Vertical axis direction" = Y-axis. and the pipe was oriented on the x-z plane, with no slope, Yes, beam location would be use same X-Z coordinates of the pipe. However, the Y-axis Coordinate would be + (OD / 2) + (distance to centroid of steel).
You can better understand by inserting a beam and see how the outside surface of the beam changes with different shapes and sizes.
