Pipes made from materials other than metals are called?

Explanation:
In sprinkler system terminology, pipes made from materials other than metals are called nonmetallic pipe materials. This term distinguishes plastic or composite piping (like PVC, CPVC, ABS, or HDPE) from metallic piping such as steel or copper. The other options refer to joining methods (solvent cement), a condition (freeze protection), or a design parameter (operating pressure), not to the material class itself. So the correct term is nonmetallic pipe materials.
