USPE utilizes APT’s MD (metallic ducting) series of piping for marina applications. This piping system provides multiple containment capability for high risk fueling installations. The metallic ducting provides a liquid tight protective covering to enhance resistance to crushing, kinking, fire, freshwater, saltwater, UV radiation, cuts, and other physical damage. The flexible nature of APT’s piping allows a variety of installation methods including hanging underneath a dock, alongside, and even underwater on a floating dock.
