The oil and gas industry occupies a strategic position in the energy matrix and in national economic development. Operations on offshore platforms, refining units, subsea systems, and onshore infrastructure require equipment and components with extremely high reliability—capable of operating under high pressures and temperatures, resisting the action of aggressive gases (such as H₂S and CO₂), withstanding abrasion and corrosion, maintaining consistent performance even during long cycles of use or long periods of inactivity.
In this demanding environment, HEF’s surface engineering solutions become decisive competitive differentiators. CLIN™ nitrocarburizing technologies (ARCOR®, SURSULF®, TENIFER® and QPQ®); PVD/PACVD deposition technologies – CERTESS® CARBON (DLC); technical engineering coatings (TEGLISS® fluoropolymers, SDA® molybdenum disulfide); and DURBORID® boriding; guarantee increased resistance to wear, seizing and corrosion, contributing to:
– Greater operational reliability and structural safety in critical oil extraction operations.
– Extended equipment lifespan, even under corrosive, abrasive environments and under pressure and heat.
– Reduction of failures, unscheduled downtime, and corrective maintenance costs.
– Improved performance in harsh operating conditions
Among the various components that benefit from HEF technologies, the following stand out: ball valves (minimizing the risk of jamming and sealing failures), components of “wet” Christmas trees (pipes, seals, valves and BOP wellheads), well drilling tools (DTH hammers).
