Wikipedia on Nominal Pipe Size (NPS) [https://en.wikipedia.org/wiki/Nominal_Pipe_Size],
 
A pipe is described by its outer diameter '''OD''', its wall thickness '''Thk''' and its height<ref>We use height instead of length  in order to make a pipe similar to a FreeCAD cylinder. These particular choice of pipe dimensions make it more compatible with pipes from flamingo workbench.</ref> H.

=== Workbench ===
 
To create a pipe, click [[File:CreatePipe.svg]] in OSE piping workbench.
Adjust CSV '''pipe.csv''' in ''tables'' directory within workbench directory to add new pipe dimensions to the list.

File:3elbow.png |'''3" PVC Elbow'''. Standard height of 4.75" as in [https://www.mcmaster.com/2389K29/]. - size:20kb - FreeCAD -[[File:3"-pvc-elbow.fcstd]],
Ab elbow is described by an angle alpha, outer pipe diameter POD, inner pipe diameter PID, H, J, M.
 
[[File:elbow-dimensions.png]]


=== Workbench ===
File:toiletparts.png| '''Toilet Parts''' - Includes closet flange, 3" elbow with 2" heel, long 3" elbow - [[File:toiletparts.fcstd]]


To create elbow click [[File:CreateElbow.svg]] in OSE piping workbench.  
File:rotatabletrap.png |'''1.5" rotatable trap''' -  FreeCAD -[[File:15rottrap.fcstd]]
To add a new elbows, adjust '''elbow.csv''' in ''tables'' directory within workbench directory.

= Couplings =
File:2doublesanteetee.png |'''2" sanitary tee''' -  FreeCAD -[[File:2doublesantee.fcstd]]


A (general) coupling is described by 10 Dimensions: POD, POD1, PID, PID1, L, M, M1, N. The dimensions POD1 and PID1 are not from a official specifications.
File:2doublefixtee.png |'''2" double fixture tee''' - Nibco site - [https://catalog.nibco.com/rfcconfirmation?name=all-categories&xcartid=27675] FreeCAD -[[File:2doublefixtee.fcstd]]
They are derived from pipe size and schedule. In a reducer coupling, the pipe dimensions on one side POD and PID differ from on the other side POD1 and PID1.

=== Macro ===
 
To install macros follow instructions in [[PVC Pipe and Fittings Library#Installation]].
 
Run [[File:create-bushing.FCMacro]] to create a reducer bushing fitting. Ensure that you have a valid bushing.csv file in the same directory as the macro.
To add new parts you need to change your bushing.csv.
* A simple CSV is here [[File:bushing.csv]].
* CSV files with more parts can also be found in [https://github.com/rkrenzler/ose-piping-library-data].

FreeCAD community provides a little tutorials for  [https://www.freecadweb.org/wiki/Macros creation] and [https://www.freecadweb.org/wiki/How_to_install_macros installation] of macros.

# Download ose-piping-library from [https://github.com/rkrenzler/ose-piping-library-data]. To run the macros you only need the content of the directory '''macros'''. The '''macros''' directory contains macro files with extension .FCMacro, drawing with dimensions .png and some .csv tables with part parameters for testing. The more realistic .CSV tables can be downloaded from [https://github.com/rkrenzler/ose-piping-library-data].
# Determine the directory where FreeCAD looks for macros: Menu "Edit"->"Preferences"->"Macro". Look at the settings "Macro path". It is for example "/home/ose-developer/.FreeCAD/Macro/".
#: [[File:freecad-macro-directory.png]]
# Now copy all files from the downloaded '''macros''' directory to the FreeCAD macro directory. In this example "/home/ose-developer/.FreeCAD/Macro/".
# Select a FreeCAD menu item "Macro"->"Macros..." then select the corresponding macro -- it startart with "create-..." and click "Create".
== How to create a pipe macro ==
Steps to create GUI:
The original instruction are taken from [https://wiki.qt.io/QtCreator_and_PySide] but I (Ruslan) have problems with them. I adjusted them to FreeCAD.
# Create with QT Designer a Dialog based on QDialog class. Save the name for example add-nps-pvc-pipe-dialog.ui.
# Convert add-nps-pvc-pipe-dialog.ui to python code running
#: pyside-uic add-nps-pvc-pipe-dialog.ui -o pipe-dialog.py
#: or call
#: pyside-uic --indent=0 add-nps-pvc-pipe-dialog.ui -o pipe-dialog.py
#: to use tabs as indention.
#: If you use the FreeCAD macro editor, pay attention that the indention of pyside-uic and of the editor are the same.
# Insert content of the methods setupUi(self, Dialog) and retranslateUi(self, Dialog) from pipe-dialog.py (How can I insert here a block of python code?) into your macro file.
== Remarks about the coupling macro ==
To create a simple coupling or a reduced we internally use a more general coupling.
This general coupling is described by 9 dimensions: POD, PID, POD1, PID1, X1, X2, N, M, M1. The dimensions POD, PID, POD1, and PID1 are derived from the pipe sizes.
The are abbreviations of '''P'''ipe '''O'''uter '''D'''iameter and '''P'''ipe '''I'''nner '''D'''iameter.
The dimensions X1 and X2 are not official dimension names.
[[File:coupling-calculations.png]]
The offset a1 is calculated in such a way, that the thinest part of the middle section is not thinner than the walls on of the both sockets.
Lengths a2, a3, a4 and angle b1 are derived from the dimensions and are only used to calculate a1.

Basics

This is a library of all the current PVC Pipe and Fittings that have been made in freecad for OSE. Many fittings can be created using OSE Piping Workbench.

Pipe dimensions used in literature

  • O.D. - outer diameter.
  • Average I.D. - average inner diameter (why average?). This dimension determines the size of the pipe.
  • Min. Wall - thickness of the pipe wall.
  • Schedule - determines (indirectly) the thickness of the wall.

Basic Parts

Parts Generated Using the OSE Piping Workbench + Other

Library of STEP Downloads from McMaster Carr

Comparable in size to generated parts - except for some parts which are way too heavy.

FAQ

  • Do we really want to 3D-print pipe fittings? Somehow I have doubt about mechanical properties of the 3D-printed products.
    Yes. For high pressure applications - 300 PSI - we would have to be very careful. For low pressure, such as 5 PSI, it's not a problem. Eventually, we want to refine printing techniques where our fittings can do what standard schedule 80 ABS fittings can do.
    • Also with things such as part baking/ annealing, composite filaments, and SLA or SLS Printers, very durable parts can be made. Granted i agree proper testing, and potentially getting "Listed" or whatever the Building Code / Insurance stuff would need
