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.


Cross

Almost General Cross

A cross is described by dimensions G, G1, G2, G3, H, H1, H2, H3, M, M1, and pipe dimensions. As pipe dimensions we use POD, POD1, PID, and PID1.

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/anealing, composite filaments, and SLA or SLS Printers, very durable parts can be made
