Oee offers a full line of pistons for duplex and triplex mud pumps. All api types are available. Among these are:
1. Bonded rubber pistons
2. Premium bonded urethane pistons
3. Pistons with replacement rubbers
Bonded rubber pistons are fully interchangeable with other api standard desig0ned pistons and delivery maximum performance in almost all drilling conditions. High tensile strength, resistance to chemicals, hydrocarbons, and abrasion, long lasting service, and full interchangeability with other api designed pistons make our premium piston a sound value.
Bonded urethane pistons have no joints to leak. But eliminates abrasive fluids between piston and liner. The fluid expanded lip is not damaged by high pressure and fast pump strokes. This fail-safe piston seals off to greater diameter as liner wears.
Premium bonded urethane pistons apply in standard environment with the longest service life of more than 500 hours, and piston hub has the longest service life of more than 450 hours.
Pistons with replacement rubbers will run in higher-pressure, fast stroking pumps, and is resistant to oil base muds and other additives currently being used. This one piece bonded unit provides the same series of advantages, being impervious to oil and other chemicals.
Normal Standard
All pistons are produced by imported acrylonitrile butadiene
rubber which suit for ordinary drilling environment under the
maximum working pressure 20MPa. The maximum working
temperature of our piston is up to 120 íµ and it is with
excellent wear resistance and good chemical corrosion
resistant .The service life of the piston can reach 280 hours
in ordinary drilling working environment.
Strength Enhanced
The material of this kind of pistons is high-intensity
acrylonitrile butadiene rubber which supplied by American
Dupont company and Japanese Zeon company. This kind of
pistons is with good oil and wear resistance as well as super
comprehensive strength, which applied to oil-based mud and
higher silt content working environment under the maximum
working pressure 35MPa as well as at the maximum working
temperature 120íµ
