What Is the Material Classification of Piston - One of the Mud Pump Accessories?

Material classification of mud pump accessories (piston):

1. Nitrile rubber

It is suitable for ordinary drilling environments where the working pressure is lower than 20MPa and the working temperature is not higher than 120℃. The nitrile rubber of the mud pump accessories has excellent wear resistance, chemical resistance and long service life in ordinary drilling environments.

2. Polyurethane rubber

It has excellent oil resistance and abrasion resistance. The working temperature is not higher than 120℃, which is suitable for oil-base mud with working pressure below 35MPa and working environment with high sand content.

3. Hydrogenated nitrile rubber

the hydrogenated nitrile rubber is suitable for working environment with high temperature, high pressure and high corrosion. Working pressure is 75MPa, working temperature can reach 150C, hydrogenated nitrile rubber of the mud pump accessories is a kind of aviation rubber. Hydrogenated nitrile rubber is used in the petroleum industry. It has good abrasion resistance, oil resistance and chemical resistance. And it also has good amine resistance and steam resistance. Especially in the working environment of high temperature and high pressure, other rubbers are rapidly destroyed under the action of hydrogen sulfide, carbon dioxide, methane, steam and acid, but hydrogenated nitrile rubber shows good overall performance.
