Tungsten Carbide Choke Bean

Wear-resistant tungsten carbide choke beans with fixed flow orifices for oilfield pressure control, abrasive fluids, and severe-service choke applications.

Wear-resistant tungsten carbide choke beans with fixed flow orifices for oilfield pressure control, abrasive fluids, and severe-service choke applications.

Product Overview

Tungsten Carbide Choke Beans are replaceable fixed-orifice flow-control components used in positive choke valves and oilfield pressure-control systems. Manufactured from cemented tungsten carbide, these choke beans provide excellent resistance to erosion, abrasive wear, and high-velocity fluid flow in demanding oil and gas service environments.

The precision choke orifice creates a controlled flow restriction and helps maintain a stable flow passage during production, well testing, flowback, injection, and other high-pressure fluid-control operations. In applications involving sand-containing fluids, abrasive particles, pressure drop, and erosive media, tungsten carbide choke beans can provide longer service life than conventional metal components.

KENIN Carbide manufactures standard and custom tungsten carbide choke beans according to customer drawings, choke size requirements, operating pressure, fluid properties, connection structure, and expected service conditions.

Applications

Tungsten carbide choke beans are widely used in fixed choke and positive choke systems requiring controlled flow restriction, erosion resistance, and reliable performance under high-pressure conditions.

Typical applications include:

Oil and gas production equipment
Wellhead and Christmas tree choke systems
Positive choke valves
Flowback and well-testing equipment
Choke manifolds
Pressure-control systems
Chemical injection and fluid-control equipment
Oilfield service tools
Sand-containing and abrasive fluid handling
High-pressure hydraulic flow-control systems
Fracturing and stimulation equipment
Production and injection flow-control assemblies

Frequently Asked Questions

Can tungsten carbide choke beans be manufactured according to drawings?
Yes. KENIN Carbide can manufacture tungsten carbide choke beans, fixed-orifice choke inserts, positive choke components, and custom flow-control parts according to customer drawings, samples, 3D files, or detailed technical requirements. Orifice diameter, outer diameter, length, inlet and outlet geometry, retaining structure, tolerance, surface finish, and carbide grade can all be customized.
What is a tungsten carbide choke bean used for?
A tungsten carbide choke bean is used as a replaceable fixed-orifice insert in positive choke valves and oilfield flow-control systems. The precision orifice creates a controlled flow restriction and helps regulate flow rate and pressure drop in high-pressure fluid applications.
Can the choke bean orifice size be customized?
Yes. The fixed orifice diameter and internal flow profile can be customized according to required flow rate, pressure drop, fluid properties, sand or particle content, choke valve design, and operating conditions.
What information is required for a quotation?
Please provide the drawing or sample, required orifice size, outer diameter, overall length, operating medium, sand or particle content, working pressure, pressure drop, required flow rate, valve model, installation dimensions, quantity, and expected service conditions.
Why choose tungsten carbide choke beans?
Tungsten carbide provides high hardness and strong resistance to erosion and abrasive wear. It is suitable for fixed choke components exposed to high-pressure fluids, sand-containing media, repeated flow service, and severe oilfield pressure-control conditions.
Can choke beans be used in sand-containing oilfield fluids?
Yes. Tungsten carbide choke beans are commonly selected for abrasive fluid service because the material can resist erosion caused by sand particles and high-velocity flow. The suitable carbide grade, orifice size, and component structure should be selected according to particle size, concentration, pressure, flow rate, and required service life.
What is the difference between a choke bean and a choke stem?
A choke bean is typically a replaceable fixed-orifice insert used to create a defined flow restriction in a positive choke system. A choke stem is generally a movable valve component used in adjustable choke or valve trim assemblies to regulate flow through its position and profile.
