Nitrile rubber
It is suitable for ordinary drilling working environment with working pressure below 20Mpa and working temperature not higher than 120℃. Excellent wear resistance, chemical corrosion resistance, long service life in ordinary drilling environment.
Polyurethane rubber
Has excellent oil resistance and wear resistance. The working temperature is not higher than 120℃, and it is suitable for oil-based mud with a working pressure below 35Mpa and a working environment with high sand content.
Hydrogenated nitrile rubber
It is suitable for high temperature, high pressure and high corrosion working environment, the working pressure is 75Mpa, and the working temperature can reach 150℃. Hydrogenated nitrile rubber is a type of rubber used in aviation. Used in the petroleum industry, hydrogenated nitrile rubber has wear resistance, oil resistance and chemical resistance, and its amine resistance and steam resistance are good. Especially in the working environment of high temperature and high pressure, other rubbers are quickly destroyed under the action of hydrogen sulfide, carbon dioxide, methane, steam and acid, but hydrogenated nitrile rubber shows good comprehensive performance.
