Piston assembly is the major part of the mud pump fluid end. The discharge pressure of mud pump is generated by the up-and-down motion of the piston in the cylinder.
Our liners can be used in various drilling operation conditions. Double metal liner coat used in forging steel production, inner the coat of premium liners is made from forged blank. Endotheca is made of the centrifugal casting high chromium materials, and the inner sleeve reach HB285-330 after normalizing. Honing roughness can reach more than Ra0.8 after grinding. Our product has the characteristics of the wear resistance, corrosion resistance,high precision and long service life. Our products can be fitted to all souts of conditions.

Tubing head is a spool with flange top, flanged bottom and two side outlets. It also can be called tubing spool. Top flange is equipped with lock screws to fix tubing hanger. Tubing head is installed on top of casing head, which consists of body housing and tubing hanger. It can hang tubing string and seal the annular space between tubing and production casing. Our company can manufacturer tubing head with standard structure, which includes tubing hanger installed on the cone of body housing. Tubing hanger can be tapped with BPV thread as per request.
FC valve
1. Full-bore design, effectively eliminate the pressure drop and eddy current, slow flow of solid particles in the valve.
2. The unique sealing, make the switch torque greatly reduced
3. Between bonnet & body and gate & seat are adopt metal to metal seal
4. Between gate and seat are adopt metal to metal seal, Surface spraying (heap) welding hard alloy , has good abrasion resistance, corrosion resistance.
5. Seat ring is fixed with plate, keep well steady
6. Stem has back seal structure so as to replace seal ring of stem with pressure
7. There is seal grease injection valve on bonnet side so as to repair seal grease , and provided seal and lubricate performance of gate and seat
8. It is match with all kind of pneumatic (hydraulic) actuator as customer's requirements
Expanding gate valve
1. Gate is fission expanding structure
2. Realizing low torque or low wear during switch
3. Between bonnet and body are adopt metal to metal seal
Casing Cup Tester is mainly used for the pressure test on the casing string and blowout preventer stack. All of the oil (gas and water) well has been running in hole with casing and has been installing the mouth of wellhead equipment, to test pressure delamination one—off for casing and control blowout pressure system, also can be used to test pressure for casing at well site pipe yard. Test pressure very easy, provided the test pressure tool put in the casing.
Mud Pump Parts Valve assembly/Valve body/Valve seat
1.The valve body and valve seat of valve assembly are made from high-quality knot steel treated with 20CrMnTi carburizing and
quenching processes.
2.The surface hardness is greater than HRC 60.
3.The conical surface is ground finished to ensure a high requirement for roughness and geometric dimension.
4.The rubber sheet is made of polyurethane material which improves the service life of valve assembly, the operational use time is more than 300 hours.
