Cu AC Valve Plate Phosphor Bronze C5191 Wear Resistant Highly Resilient

Cu-AC-ValvePlate Phosphor Bronze C5191 Wear Resistant Highly Resilient

1, Product Overview

Designed for use in extreme hydrogen sulphide (H₂S) environments, our C17200 beryllium-copper alloy oil drilling tool couplings combine superb strength, hydrogen embrittlement resistance and corrosion resistance, making them ideal for use in deep-sea drilling, high-acid gas fields, and high-temperature, high-pressure downhole operations.
