PDF Download: Locatable Plastic Methane Pipe to Reduce Excavation- Related Gas Explosions
Publication: Application PCT

PVC/Polyethylene pipes with parallel longitudinal conductive traces on the outer surface. The conductive trace comprises of a long laser scribed graphene trace, spray coated with metal and finally protected by an insulation material. The conductive traces are connected to a power source or a repeater

Opportunity

Seeking gas utility, pipe manufacturing, infrastructure, and safety partners to reduce excavation-related methane-pipe strikes.

Problem Statement

Natural gas distribution is increasingly dependent on plastic pipe because it is corrosion-resistant and practical to install. Unlike metal pipe, buried plastic pipe cannot be located directly with conventional electromagnetic pipe locators unless a tracer wire, marker tape, or records are accurate and intact. When plastic methane lines are missed, mismarked, or damaged during excavation, gas can migrate underground, enter buildings, and ignite. Recent gas explosions show that line strikes and poor utility location can destroy buildings, injure workers and residents, cause fatalities, interrupt service, and create major liability for utilities and contractors.

Solution

Researchers at the University of Missouri have developed a platform technology that integrates conductive structures directly into the walls of plastic pipes. For methane distribution pipes, these structures could enable the pipes themselves to emit or carry a detectable signal, making buried plastic gas lines easier to locate before excavation. The same pipe-integrated architecture may also support future leak detection, strain or damage monitoring, pressure and temperature sensing, and communication with utility asset-management systems.

Value Proposition

This technology addresses an immediate pain point for gas utilities: buried plastic methane pipes can be safer if the pipes themselves are locatable. A pipe-integrated signal path could reduce dependence on separate tracer wires and inaccurate records, improve excavation safety, reduce third-party damage, and support more reliable utility mapping. The first commercial case is clear: a smart methane pipe that helps prevent catastrophic line strikes. The wider opportunity is a new class of gas-distribution pipe that is locatable, monitorable, and ready for future intelligent infrastructure applications.
