Oil & Gas Carbide Components

Oil & Gas Carbide Components

Tungsten carbide components for oil and gas drilling, choke systems, valves, pumps, sealing, flow control, and abrasive high-pressure service.

KENIN Carbide manufactures tungsten carbide components for oil and gas equipment operating under abrasive fluids, high pressure, erosion, repeated throttling, sealing contact, and demanding flow-control conditions.

Our oilfield carbide components are designed for choke valves, wellhead equipment, pressure-control systems, pumps, drilling tools, mechanical seals, flow-control assemblies, and abrasive fluid-handling equipment. Depending on the operating medium, sand content, pressure, temperature, flow rate, impact conditions, mating components, and required service life, we can review carbide grade, geometry, tolerance, sealing surfaces, flow passages, and mounting structures before production.

From choke stems and choke beans to valve balls and seats, carbide sleeves, seal rings, nozzles, drilling components, and other non-standard oilfield wear parts, KENIN Carbide supports drawing-based and sample-based custom manufacturing.

Quick Carbide Grade Selection Guide

There is no single carbide grade that fits every application. The right grade depends on the balance between wear resistance, toughness, corrosion resistance, dimensional stability, and actual working conditions.

What Makes a Carbide Grade

Cemented carbide is an engineered material made mainly from tungsten carbide particles and a metallic binder such as cobalt or nickel.

By adjusting the tungsten carbide content, binder type, binder percentage, grain size, hardness, and toughness, different carbide grades can be designed for different working environments.

  • Higher tungsten carbide content generally provides higher hardness and better wear resistance.
  • Higher cobalt binder content generally improves toughness and impact resistance.
  • Nickel-bonded carbide grades can provide better corrosion resistance for pump, valve, sealing, and fluid-control applications.
  • Fine-grain carbide grades are suitable for precision wear and stable dimensional performance, while tougher grades are preferred for impact, pressure, and heavy-load conditions.

Match the Grade to Your Working Conditions

Before selecting a carbide grade, the actual working conditions should be reviewed carefully.

Working Condition Recommended Selection
Abrasion or Sliding Wear For general wear parts under normal working stress, balanced wear-resistant grades such as YG6 or YG8 are commonly selected.
Impact or Heavy Load For forming parts, cold heading dies, stamping dies, or high-stress applications, tougher grades such as YG15 or YG20 are more suitable.
Corrosion or Fluid Contact For pumps, seal rings, valve balls, or acidic working environments, nickel-bonded corrosion-resistant grades such as YF06N can be considered.
Rock Drilling or Mining Impact For DTH bits, cone bits, reamer bits, and medium-hard rock formations, mining tool grades such as YK06, YK10, or YK11 are recommended.

Recommended Grades by Application

Working Condition Typical Applications Recommended Grade Key Feature
Abrasion or sliding wear General wear parts under normal working stress YG6 / YG8 Balanced wear resistance, strength, and toughness
Impact or heavy load Forming parts, cold heading dies, stamping dies, high-stress parts YG15 / YG20 Higher toughness and impact resistance
Corrosion or fluid contact Pumps, seal rings, valve balls, acidic environments YF06N Nickel-bonded, wear-resistant, corrosion-resistant
Rock drilling or mining impact DTH bits, cone bits, reamer bits, medium-hard rock formations YK06 / YK10 / YK11 Good wear resistance and toughness for rock drilling

The above recommendations are for reference only. Final grade selection should be confirmed based on drawings, working conditions, wear requirements, impact load, corrosion exposure, surface finish, and dimensional tolerance requirements.

Custom Carbide Manufacturing Process

KENIN Carbide supports custom tungsten carbide components based on drawings, photos, samples, dimensions, carbide grade requirements, and working conditions. From requirement review to production and delivery, we provide a clear and efficient process to help customers complete custom carbide projects.

  1. Submit Your
    Requirements

    Send us drawings, photos, samples, dimensions, specifications, quantity, carbide grade requirements, and working conditions. If the grade is unclear, describe the wear, impact, corrosion, or performance needs, and we will review the application.

  2. Quotation and
    Confirmation

    We review the product structure, carbide grade, tolerance, quantity, processing difficulty, and delivery schedule. Before production, we confirm dimensions, grade, surface finish, packaging, and delivery details with you.

  3. Production and
    Quality Control

    Production starts after the order is confirmed and technical details are approved. Depending on the product, the process may include pressing, sintering, CNC machining, grinding, polishing, and final inspection.

  4. Packaging and
    Delivery

    Finished parts are cleaned, protected, and packed to reduce transportation damage. Shipment is arranged according to the agreed method, and logistics information is provided after dispatch.
