Cerakote for Oil & Gas: Maximum Service Life in the Field

In the oil & gas industry, threaded connections are often the "single point of failure." Thick epoxy or powder coatings cannot be used here as they would exceed tolerances and hinder assembly; threads therefore often remain raw and unprotected. Cerakote solves this problem with an ultra-thin, uniform layer that coats every thread flank without altering the profile. This protects even the finest premium connections completely from corrosion and cold welding, significantly extending the lifespan of couplings and and fittings in corrosive media.

Valves, chokes, pumps, and impellers are constantly exposed to high flow rates, pressure fluctuations, and sometimes abrasive media containing sand or solids. Conventional coatings chip off at edges or are quickly eroded in throttling zones, exposing the bare metal and leading to corrosion. Cerakote offers a hard, highly adhesive protective layer that resists both corrosive and erosive attacks. Due to the thin layer, valve characteristics and flow rates are maintained, while the time until the first rebuild or replacement is significantly extended.

Downhole tools, frac plugs, and peripherals such as spools or fittings operate in an extreme mix of pressure, temperature, chemicals, and salt/formation water. Field reports show that epoxy-coated parts often fail at unprotected threads, while components fully coated with Cerakote can extend their service life from a few months to periods of over a year and more. The ability to continuously coat internal bores, threads, external geometries, and transitions without masking prevents weak points in the system and significantly increases the operational availability of frac and drilling fleets.
