- Information
Sucker rod pumps stand as the core equipment for crude oil lifting. Their operational stability directly dictates oilfield productivity and costs. However, harsh downhole conditions, such as high sand content, severe corrosion, and high temperatures, frequently plague traditional pump valve structures, leading to seal failure, component wear, and oil backflow, thereby severely limiting oil recovery efficiency. The cobalt alloy valve cage, with its exceptional performance, has emerged as the ideal material for advanced valve structures and overcoming complex well challenges.

Product Features
1. High temperature resistance
The strength keeps stable up to 800℃ and it can even momentarily used at 1200℃.
2. Wear resistance
Due mainly to the unique inherent characteristics of the hard carbide phase dispersed in a
CoCr alloy matrix, it has exceptional wear and galling resistance.
3. Corrosion resistance
This exellent and lovely property allows this kind of material parts to be used in oil&gas, slurry, acid liquid and any other mediums.
