Short Description:
* API certified manufacturer
* Tungsten Carbide, Nickel/Cobalt/Titanium Binder
* Sinter-HIP Furnaces
* Sintered, finished standard, and mirror lapping ;
* Additional sizes,tolerances, grades and quantities are available upon request.
Pump valves are made of balls and seats and they are a key component when working under high hydraulic pressure due to depth. Only a perfect design and a correct selection of the material can guarantee their service life.
Valve balls and valve seats are widely used in oil fields , their performance directly affects the use effect and service life of the pumps. Each ball-and-seat combination is vacuum tested to ensure a perfect seal is obtained in all positions of contact.
Tungsten carbide ball & seat, made from virgin raw materials, have high hardness, wear-resistance, corrosion resistance, and resistance to bending. We are able to supply Carbide Balls in various desired material specifications including TC Cobalt, TC Nickel and TC Titanium, and the TC Balls are manufactured as per ISO and Anti-Friction Bearing Manufacturer Association (AFMBA) standards.
The tungsten carbide valve ball and seat will be used widely to the stationary and roving unidirectional valve in various tube-type oil suction pump due to their high hardness, wear and corrosion resistance as well as good anti-compression and thermal shock characters with a high pumping effect and a long pump check cycle for raising of sand, gas and wax containing thick oil from wells.
Blank balls and finished balls can be both supplied. Standard and non-standard balls are available.
API 11AX Compliant Engineering for Subsurface Pumps
At Guanghan N&D Carbide Co., Ltd, we specialize in manufacturing heavy-duty Tungsten Carbide Balls and Seats fully compliant with strict API Spec 11AX standards for subsurface sucker rod pumps. Serving the global oilfield sector for 22 years, our precision-engineered valve pairs function as the intake and discharge gates within the pump barrel, keeping production consistent under the most grueling downhole conditions.
Our API 11AX valve balls and seats are designed to withstand violent fluid pounding, high-sand concentrations, and hydrodynamic cavitation, eliminating catastrophic traveling/standing valve leakage and reducing costly workover frequencies.
Our API 11AX Ball and Seat pairs are the industry standard for artificial lift operations, performing flawlessly across diverse oilfield environments where conventional steel valves fail prematurely:
Sandy & Heavy Oil Reservoirs: Deployed in high-viscosity wells to resist severe abrasive wear caused by formation sand, proppants, and solid debris suspended in the crude oil.
Corrosive & Sour Gas Wells (H2S & CO2 Environments): Specially engineered nickel-binder valve seats prevent hydrogen embrittlement and galvanic corrosion, maintaining structural integrity in presence of sour gas.
Deep Well & High-Pressure Artificial Lift: Capable of supporting immense hydrostatic fluid columns and axial loads in ultra-deep wells without deformation or micro-cracking.
Coalbed Methane (CBM) & Submersible Pumping: Ideal for specialized dewatering pumps requiring constant rotary and vertical fluid control under continuous operational duty.
ND Carbide does not operate as a generic distributor; we are an audited, 22-year ISO & API certified source factory. We provide comprehensive engineering services
Full Range of API Standard Sizes: We manufacture all standard API 11AX dimensions, including popular specifications like V11-106, V11-125, V11-150, V11-175, V11-200, V11-225, V11-250 and V11-375 valve ball and seat sets.
Vacuum Testing & Flawless Mirror Finish: Every single ball and seat pair undergoes rigorous internal vacuum testing to ensure a 100% leak-proof seal. Our precision lapping centers achieve perfect sphericity and surface finishes.
100% Custom Tolerance Matching: Beyond standard API specs, we support full non-standard customization from your technical prints, internal angles, and specific grade ratios.
14-Year Expert Technical Support: Directed by an elite engineering team with 14 years of professional oilfield wear-component experience, we provide onsite material optimization and immediate global logistics fulfillment.
We offer you valve ball and seat pre-sale services, after-sale services which including sales guidance, information supply & technical support, technical drawing supply, production planning provide, production schedule provide, inspection support and certificate provide.
