Abstract
This disclosure describes a reinforced thermosetting resin piping system that is protected from external impact and UV damage by an outer polyurea-based layer. The embodiments described herein can be favorably used for underground and aboveground applications. In some implementations, an RTR pipe includes a core layer that includes a resin and fibers, an outer layer that includes a polyurea-based layer, and an interface layer between the core layer and the outer layer. The methods described herein also outline the process of producing the pipe structure.
