PVC Pipe and Fittings Library

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.

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
