Types include Vulcanized Rubber Pistons, Vulcanized Polyurethane Rubber Pistons, Packaged Rubber Pistons, ect.
Types
Vulcanized Rubber Pistons
This kind of piston is made of special nitrile rubber which has a good performance of heat resistance, oil resistance, water resistance, suite to use in the working condition of high pressure, long stroke etc., especially suited to use on the liner that has a certain abrasion.
Vulcanized Polyurethane Rubber Pistons
This kind piston is to vulcanize the piston rubber on the piston hub directly, no need to use plates and snap rings, it suite to all kinds of mud especially suit to use on high pressure jet drilling and ceramic liners with long service life. It can be interchangeable with other pistons that manufactured according to API Standard.
Packaged Rubber Pistons
This kind pistons are conform to API Standard and has very good performance in various drilling conditions. The piston hub is processed with premium forging steel. The piston rubber is made from specially formulated compounds which are resistant to the effects of heat, oil and water. The multi-ply fabric reinforced backings used in the production of the piston rubbers has high tensile strength, chemical products resistance, wear resistance and has long service life. This kind of piston can be interchangeable with other pistons that manufactured according to API Standard.
