Abstract: A process for manufacturing pipes using thermoplastic pipe and “tape” (continuous fiber, fully wetted in a similar thermoplastic as the pipe) that embeds the fibers into pipe surface. In one embodiment, an ambient temperature (72 degrees F.) tape is tightly wrapped around the cold pipe in a dry environment (relative humidity below 30).

A protective film is applied to the pipe. Portions of the tape and film are scraped from the surface of the pipe creating an area where the end of the pipe is coupled to another pipe using an electronic fusion coupler.
