In process of operating the gas metering devices that are intended to meter gas consumption, volume, pressure, temperature while gas flow is moving, some of the surfaces are subjected to direct contact with the aggressive medium.
As a consequence it causes service lifetime shortening, and corrosion destruction of these devices.
In order to solve this issue, the designer and manufacturer of the gas metering devices addressed to the Modengy company for the purpose of selecting a protective coating resistant to exposure to hydrogen sulfide.
MODENGY 1014 anti-friction solid-film coating based on polytetrafluorethylene and molybdenum disulfide was applied onto the surfaces of the gas devices piezoelectric sensors cases directly contacting to hydrogen sulfide.
It has resistance to various chemically aggressive media including hydrogen sulfide, high anticorrosive properties, long service lifetime.
MODENGY 1014 coating is applied by the method of spraying onto the preliminary prepared surfaces of the parts, and get polymerized at heating in a kiln. After curing, it requires no renewal during a long while, in many cases even for the entire service lifetime of the treated elements.
Application of this coating on the gas devices sensors parts enables to prevent corrosion destruction, and to provide long trouble-free functioning of the equipment.
