Flow Control
A collection of cemented carbide grades developed specifically for flow control in the oil and gas industry. Our grades excel in aggressive environments that often include corrosive, abrasive and impacting elements.
Industry Pain Points
- Trim eroding so the recorded choke setting no longer matches the actual flow rate.
- Sand laden production cutting a steel trim out within weeks.
- Replacement beans that do not seat correctly in an existing choke box.
- A graduated bean set with one size permanently missing.
What Buyers In This Sector Ask For
- A calibrated bore that stays calibrated through the run.
- Beans, seats, points and cages from one grade so wear stays even.
- Dimensions that fit the choke body already in service.
- Full graduated sets supplied from one production lot.
Typical Application Scenarios
Positive Choke Valves
Calibrated beans in 1/64 inch steps screwed into a fixed choke box.
Choke Manifolds
Bean changes as the well is brought on and the rate is stepped up.
Adjustable Chokes
Seat and point pairs trimming flow under pressure.
Cage Chokes
Cages spreading the pressure drop across a set of ports.
Well Testing
Graduated bean sets carried to site for a stepped test programme.
Water And Sand Service
Media covered by the range include oil, gas, water and sand.
How A Project Runs
From the first enquiry to the packed carton.
- Step 01
Enquiry And Grade Advice
Send the drawing or the failed part. We come back with a grade and preform recommendation, usually within 24 hours.
- Step 02
Sample Or First Article
A sample or first article is agreed before the main batch is pressed.
- Step 03
Production
Milling, forming, sintering under pressure and finishing on our own line in Chengdu.
- Step 04
Inspection And Despatch
Density, hardness and dimensions checked, then out by FedEx, DHL, TNT, UPS or air cargo.
Delivery Capability

- Exported to Germany, the United States, Russia, Australia and other countries.
Frequently Asked Questions
Which choke does your liner fit?
The professional dimensional liner we supply suits the choke bean of the Cameron type H2 Big John, with a 410SS body. Other bodies are quoted from a sample or drawing.
What bore range do you cover?
3/64 inch to 64/64 inch in 1/64 inch steps, item numbers CH-03-5875 to CH-64-5875.
Do you make the rest of the trim?
Yes. Chokes, seats, points and cages are all part of the flow control range.
Which grades do you use for flow control?
Grades developed to excel in aggressive environments with corrosive, abrasive and impacting elements. YG6, YG8 and YG10X are typical, and YN6 and YN10 are available where the part must be non-magnetic and corrosion resistant.
