Tungsten Carbide Sleeves and Bushings

Oilfield tungsten carbide sleeves and bushings for downhole tools, valves, pumps, flow-control equipment, and abrasive wear protection.

Oilfield tungsten carbide sleeves and bushings for downhole tools, valves, pumps, flow-control equipment, and abrasive wear protection.

Product Overview

Oilfield Tungsten Carbide Sleeves and Bushings are wear-resistant components designed for demanding oil and gas equipment operating under abrasive fluids, high pressure, sand-containing media, repeated movement, and severe service conditions.

Manufactured from cemented tungsten carbide, these sleeves and bushings provide excellent hardness, erosion resistance, dimensional stability, and long service life. They are commonly used to protect mating shafts, guide moving components, support rotating parts, control clearances, and reduce wear in oilfield valves, pumps, downhole tools, pressure-control equipment, and fluid-handling systems.

Compared with conventional steel or alloy components, tungsten carbide sleeves and bushings can maintain critical bore dimensions and wear surfaces for longer periods in abrasive or high-pressure environments. This helps reduce maintenance frequency, improve equipment reliability, and extend the service life of valuable oilfield assemblies.

KENIN Carbide manufactures standard and custom tungsten carbide sleeves, bushings, wear sleeves, guide bushings, valve bushings, pump sleeves, and other oilfield wear components according to customer drawings, samples, assembly structures, operating media, and service requirements.

Applications

Oilfield tungsten carbide sleeves and bushings are widely used in equipment requiring wear resistance, stable clearances, accurate guidance, and long service life in abrasive or high-pressure environments.

Typical applications include:

Downhole drilling tools
Oilfield valves and flow-control assemblies
Choke valves and pressure-control equipment
Mud pumps and slurry pumps
Oil and gas production equipment
Wellhead and Christmas tree components
Mechanical seal assemblies
Pump shafts and rotating equipment
Valve guides and stem support components
Chemical injection equipment
Hydraulic control systems
Abrasive fluid and sand-containing media handling

Frequently Asked Questions

Can oilfield tungsten carbide sleeves and bushings be manufactured according to drawings?
Yes. KENIN Carbide can manufacture tungsten carbide sleeves, bushings, guide bushings, wear sleeves, valve bushings, pump sleeves, and other custom oilfield wear components according to customer drawings, samples, 3D files, or detailed technical requirements. Inner diameter, outer diameter, length, grooves, steps, flanges, surface finish, tolerance, and carbide grade can all be customized.
Can the carbide grade and surface finish be customized?
Yes. Carbide grades can be selected according to pressure, abrasive particles, sand content, load, working medium, temperature, rotational speed, and required service life. Surface finishes including precision grinding, polishing, lapping, and customized sealing or guide surfaces are available according to drawing requirements.
What information is required for a quotation?
Please provide the drawing or sample, inner diameter, outer diameter, length, mating shaft or component dimensions, operating medium, sand or particle content, working pressure, temperature, rotational speed or movement condition, quantity, tolerance requirements, and expected service conditions.
What is the difference between a tungsten carbide sleeve and a tungsten carbide bushing?
A tungsten carbide sleeve is generally used to protect a shaft, housing, or rotating component from wear. A tungsten carbide bushing is more commonly used as a guide, support, wear surface, or positioning component inside an assembly. The final naming and design depend on the equipment structure and operating conditions.
Can tungsten carbide sleeves and bushings be used in sand-containing oilfield fluids?
Yes. Tungsten carbide is widely used for oilfield components exposed to abrasive particles, sand-containing fluids, slurry, drilling media, and erosive flow. The suitable carbide grade, sleeve geometry, wall thickness, bore design, and surface finish should be selected according to particle size, concentration, pressure, flow rate, and expected service life.
Can carbide sleeves be supplied with grooves, holes, slots, or stepped structures?
Yes. KENIN Carbide can manufacture custom grooves, lubrication holes, retaining features, slots, steps, flanges, chamfers, and other functional structures according to customer drawings and assembly requirements.
