Solution - Plating on drills for oil drilling

Company F, involved in oil drilling equipment, faced an issue where the pressure gauge diaphragm made of a special iron alloy was failing quickly due to metal fatigue.

The client approached Mitsuya to inquire about the cause and potential surface treatment solutions.

We suspected that hydrogen sulfide in the crude oil was the cause of the failure. In response, we developed a prototype using a combination of plating methods and received positive evaluation.

Although the sand and sulfides in the crude oil, as well as the exact duration of exposure, were unknown, our provisional plating specifications demonstrated that they could withstand up to 7 years of use and still maintain a 3-year lifespan even in harsh conditions.
