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.

Ram type BOPs are field proven products that are designed for a variety of operations from workovers to high pressure, critical service operations for land drilling and subsea service. It consists of the BOP body, bonnet, hydraulic cylinder assembly, operating piston, ram change cylinder, ram opening/closing piston, locking screw, ram assembly, sealing parts etc. Top, bottom and outlet connection dimensions conform to Specification for Drilling through Equipment API Spec 16A.
Made up of the high-strength and high-tenacity alloy steel, the pressure-bearing parts (like BOP body, bonnet etc.) are formed through external refining and proper heat treatment, preventing the harmful chemical components and nonmetallic inclusion strictly from materials and ensuring BOP to be safe and reliable. The body ram chamber adopts the long runway to reduce stress concentration. Both the bonnet switch and ram switch are driven by the hydraulic pressure and adopts the same one oil line. The bonnet employs the same one oil line and operation to open and close the ram. Moreover, the bonnet employs the same one oil line and operation to close and open the ram.
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.
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.
