API 7K F-1000 triplex drilling Mud Pump and spare parts

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 

API 6A Check Valve, also referred to non-return valve, or one-way valve, is a valve that normally allows fluid (liquid or gas) to flow through it in only one direction. An important concept in check valves is the cracking pressure which is the minimum upstream pressure at which the valve will operate. We can produce both swing type check valve and lift type check valve. Available in bore sizes from 1-13/16" to 7-1/16" and pressure ratings from 2,000 to 15,000 PSI. The standard material is forged AISI4130 alloy. All of our Check Valves are fully designed, manufactured, and tested as per API 6A and API 16C standards and have been widely used on oilfield wellhead Christmas tree and manifolds with reliable performance. 

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.
