Pipes, yes (but hard). Ducts, no. Ducts really don't know anything about
their materials currently. There is a "roughness" applied to the ducts, and
it is simply editable so you can change it for whatever material you would
like, just create a new duct type and change the roughness.
Pipes: If you look in your installation folder (the same place that
Revit.exe is) there is a file called PipeSizes.xml. This file contains the
information on the pipe materials, roughness, connection types, and classes
that are available in the application. For each new material there is a name
and roughness, a list of connection types, a list of nominal sizes, a list
of classes, then a list of ID's and OD's for each nominal size and class.
Adding a new mateiral for PEX would look something like this (although I
made up the ID and OD values, so please don't use them)

You'll need to close and re-open revit systems for the xml file to be read
if you make changes.
PLEASE make a copy of the file before you start to edit it. Editing XML
isn't horribly fun and there isn't much there to tell you if you happen to
have a typo anywhere.

Is there a way to add other materials to the pipe and ductwork. At this
point for piping there is only copper, carbon steel, ductile iron, plastic,
and stainless steel. I would like to add Pex tubing and few others. Where
is the file that lists the properties for these pipes? thank you for your
help.
