CARAPACE is a high performance freeze protected potable water pipe constructed of virgin high-density 200 PSI polyethylene resins certified for potability. Heat-Line is an advanced freeze protected pipe system supplied with the self-regulating heat trace factory installed inside of 75 PSI certified polyethylene pipe. Both solutions are ideal for new installations or for older water systems where new pipe is required. Installers can shallow bury or allow either product to remain above the ground with the use of pipe insulation.
