Thermal Coatings for Natural Gas Utilities & Distribution
Meters, valves, and regulator stations across a gas distribution network face two recurring problems: winter icing and condensation driven by pressure-drop cooling, and corrosion under insulation wherever moisture gets trapped against the steel. Cool Touch is a thin-film coating that addresses both — field-proven across three consecutive Michigan winters.
The Challenge
Regulating equipment runs cold, gets wet, and freezes — every winter
Gas distribution networks rely on metering and pressure-regulating equipment that cools itself by design: as gas expands across a regulator or valve, it drops in temperature (the Joule–Thomson effect, roughly 6–8°F per 100 psi of pressure reduction). That cold gas chills valve bodies, meter runs, and piping from the inside, pulling exterior metal surfaces below the dew point — and in winter, below freezing.
The result is recurring icing and condensation on outdoor flow meters, valves, and instrumentation, even where covers and electric heat tracing are already in place. Covers can trap moisture, and heat tracing adds continuous energy draw, wiring, and failure points without changing the surface-temperature behavior that causes the problem. As soon as conditions turn cold and humid, icing comes back.
The same persistent moisture also drives corrosion under insulation (CUI) wherever covers or wraps hold water against the metal — a year-round reliability risk that compounds the seasonal icing problem at regulating and metering stations.
The Solution
A thin-film barrier that stabilizes surface temperature in both directions
Cool Touch applies directly to valves, meters, regulator bodies, and piping as a thin, seamless film built on NanoTech's Insulative Ceramic Particle (ICP™) technology. By reducing heat flux through the metal, it stabilizes surface temperature relative to ambient conditions — keeping cold equipment closer to ambient (and above the dew point) in winter, and bringing hot equipment at compression or processing points into safe-touch range where applicable.
Because the coating bonds to the substrate instead of wrapping it, it eliminates the moisture trap that creates CUI in jacketed systems, while conforming to the valve bodies, fittings, and instrument geometry that make wrapped insulation impractical on regulating equipment.
Why gas utility operations and reliability teams choose Cool Touch
Eliminates recurring winter icing
Stabilizes meter and valve surface temperature above the dew point — ice has nothing to accrete on.
Reduces heat-trace dependence
Passive thermal stabilization lowers reliance on electric heat tracing, its energy draw, and its failure points.
Stops CUI at regulating stations
Seamless, adhered film — no jacket or wrap to trap moisture against carbon steel.
Keeps instrumentation accessible
Thin-film, conforms to fittings — gauges, linkages, and bolting stay accessible for inspection.
Field-proven across 3 winters
Documented performance on outdoor flow meters and valves through repeated snow and freeze cycling.
Conforms to complex valve geometry
Spray, hopper, roller, or brush application follows the geometry that's difficult to wrap with conventional insulation.
Natural gas utility scenarios
Regulator & metering stations
The Joule–Thomson cooling point in the network — where pressure drop chills equipment and condensation risk is highest.
Outdoor valves & flow meters
Exposed equipment that ices over and disrupts flow stability and instrument readability every winter.
Pressure-reduction equipment
District regulator stations and odorization equipment exposed to the same cold-gas, humid-air dynamics.
Aboveground transmission & distribution piping
Exposed runs that lose thermal energy and face condensation risk in cold and cyclic service.
Compressor & processing equipment
Hot-side equipment in the same network where safe-touch surface temperature and CUI prevention both apply.
Instrumentation & gauge protection
Ports, linkages, and bolting that ice over or corrode when wrapped in traditional moisture-trapping insulation.

Origin
A Michigan natural gas operator applied Cool Touch to outdoor flow meters and valves that had iced over every winter despite covers and heat tracing. The 5 mm coating build eliminated major ice accumulation and kept equipment running reliably through three consecutive winters in a lake-effect snowbelt that saw roughly 186 inches of snowfall in the 2024–25 season alone.
Natural gas utility coating FAQs
Yes — in documented field use, a 5 mm coating build eliminated major ice accumulation on outdoor flow meters and valves across three consecutive winters. The coating reduces heat flux and stabilizes surface temperature closer to ambient, keeping the surface above the dew point under most conditions so condensation — and the ice that forms from it — has little chance to develop.
