The dimensions of the PVC pipes can be found here [[PVC_Pipe]].
Wikipedia on Nominal Pipe Size (NPS) [https://en.wikipedia.org/wiki/Nominal_Pipe_Size],


We will use following guide line for position of a pipe: put one end (base) of the pipe onto the x-y plane. The center of the base has coordinate (0,0,0). The other end is points to the positive  direction of the z-axis.
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]].


Rationale: This is the same way FreeCAD places a new cylinder. We mimic the FreeCAD behavior for UI consistancy.

The default pipe length is 1ft. This is an arbitrary choice. When I use a macro, it will store the last length used by the user.

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.

Seed Eco-Home 6

  • Plumbing file - [8]

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
