Related to oil drilling equipment Company G.
The pressure gauge diaphragm made of a special iron alloy is destroyed in a short time due to metal fatigue.
The client came to Mitsuya to ask about the cause and the surface treatment method for countermeasures.
We presumed that the hydrogen sulfide contained in the crude oil was the cause,
and we developed a prototype using a combination of plating methods and received an evaluation.
Although the sand and sulfides contained in crude oil and the duration of flight were unknown from the data, it became clear that the provisional plating specifications developed by our company could be maintained for 7 years, and that it had a life of 3 years even in a harsh environment.
