Centrifuges are built to separate solids from liquids at high rotational speed, but the same process that makes them effective also creates intense wear. In abrasive service, components inside the bowl, conveyor, feed zone, and solids-discharge area can lose material quickly. Langsun Carbide manufactures tungsten carbide wear parts for centrifuges to help protect these high-wear zones, preserve critical geometry, and support longer, more stable operating cycles.

• Centrifuge tilesfor conveyor/scroll flight protection
• Discharge-port insertsor wear liners
• Slurry-distribution port wear parts
• Feed-zone wear protection parts
• Wear bushings / sleevesin selected locations
• Custom carbide partsfor OEM centrifuge wear points

In decanter centrifuges, tungsten carbide wear parts effectively protect the centrifuge’s wear-prone areas, as they are directly exposed to abrasive solids, high-speed flow, and continuous mechanical scraping or conveying action.

A tungsten carbide drill bushing is a precision guide component used in jigs, fixtures, and tooling setups to help locate, guide, and support cutting tools such as drills, reamers, taps, and counterbores. In production machining, the bushing helps keep the tool aligned as it enters the workpiece, improving repeatability and reducing the risk of tool wander, positional error, and inconsistent hole quality.

• High wear resistance 
• Long-run production 
• Stable tool guidance 
• Custom to drawing 
• Precision fixture components

Carbide drill bushings are commonly used where repeatability, long service life, and dimensional stability matter more than simply using a lower-cost standard guide.

Slurry pumps work in one of the harshest wear environments in industry. Abrasive solids, high-velocity flow, pressure variation, and seal-area contamination can quickly damage conventional sleeves and bushings. Langsun Carbide manufactures tungsten carbide bushings for slurry pumps to help protect critical rotating interfaces, reduce geometry loss, and support more stable pump operation in abrasive service.

• Material: Tungsten carbide
• Size: Customized according to customer requirements and drawings
• Binder: Cobalt, nickel; customized according to customer requirements
• Tolerances: Customized according to customer requirements

Langsun Carbide specializes in custom manufacturing and can produce slurry-pump bushings according to customer drawings, samples, and technical requirements.

A tungsten carbide valve disk is a wear-resistant, disc-shaped valve-trim component used in severe-service flow-control systems where the disk must maintain its geometry under erosive flow, pressure drop, repeated cycling, or solids-bearing media. Depending on the valve design, this part may function as a control disc, a front/back disc, a rotary disc trim element, or another custom disc-style component inside a choke, throttling, or other specialized valve assembly.

• Valve disk
• Valve disc
• Control disc
• Tungsten control disc
• Front disc / back disc
• Disc trim

Langsun Carbide specializes in custom manufacturing and can produce valve disks according to customer drawings, samples.

Langsun Carbide manufactures custom tungsten carbide bottom sleeves for MWD and LWD tools. These parts are used in lower downhole assemblies where a sleeve must resist abrasive drilling fluid, preserve critical geometry, and maintain reliable fit with adjacent components. Depending on the OEM design, the part may be supplied as a standard bottom sleeve, an all-in-one bottom sleeve, or a sleeve integrated with nearby lower-assembly features.

• Bottom Sleeve
• Carbide Bottom Sleeve
• MWD Bottom Sleeve
• LWD Bottom Sleeve
• Lower Assembly Sleeve

If you provide the part drawing, we can confirm the exact configuration required.

A tungsten carbide poppet is a precision wear component used in severe-service fluid-control systems where a moving poppet must repeatedly seal, open, and regulate flow under abrasive, erosive, or high-cycle conditions. Langsun Carbide manufactures custom carbide poppet parts for downhole telemetry tools, oil & gas flow-control components, and other demanding OEM applications where geometry stability and wear resistance matter.

● Poppet ends

● Poppet tips

● Valve poppets

● Poppet-and-seat components

● Custom flow-control parts

Best performance comes from matching poppet geometry, seat geometry, carbide grade direction, and service conditions to the actual tool design.

A tungsten carbide valve cage is a severe-service trim component used in control valves, choke valves, and other high-pressure flow-control assemblies where the cage must do more than “hold parts in place.” In the right valve design, the cage helps guide the plug, define the throttling area, and protect the flow path from erosive wear. Langsun Carbide manufactures custom carbide valve cages for demanding oil & gas and industrial flow-control applications.

• Ported cages for plug-and-cage valve trim
• Flow-control cages for choke valves
• Single-stage and application-specific multi-port geometries
• Custom drilled-hole or slot-type cage trim

Langsun Carbide manufactures custom tungsten carbide wear parts for Measurement-While-Drilling (MWD) and Logging-While-Drilling (LWD) tools. These components are used in downhole systems that must transmit real-time directional and formation data while surviving abrasive drilling mud, high flow velocity, pressure cycling, and continuous mechanical wear.

• Pulser components
• Valve seats and valve ends / poppet tips
• Main orifices and fluid restrictors
• Erosion sleeves, bushings, and wear rings
• Nozzles and flow-control parts
• Rotors, stators, and selected wear pads / stabilizing wear parts
• Muleshoe inserts and other custom precision wear components

If your drawing uses a different naming system, send the part print or sample. We build to the actual component function and geometry, not just the label.

Rock drilling inserts are cemented-carbide cutting elements used in drilling tools where abrasion, impact loading, and dimensional stability all matter. Langsun Carbide supplies tungsten carbide rock drilling inserts for quarrying, tunneling, water well drilling, Designed to deliver enhanced durability and cutting strength, improving drilling efficiency.

NEW ribbed insert design (front/back + bottom ribs)

● Easier assembly:ribs provide positive “location” during setup, reducing trial-and-error alignment.

● Improved positioning accuracy:clearer datum contact helps keep the insert seated consistently in the pocket.

● More consistent joints:improved seating helps support symmetrical brazed/welded seams and reduces uneven stress concentration.

Pump bushings are not “generic sleeves”—they are wear interfaces that protect critical rotating hardware and help maintain stable clearances under abrasion, erosion, corrosion-assisted wear, and vibration. Langsun Carbide manufactures tungsten carbide pump bushings for harsh-duty fluid handling, including slurry and chemical services.

● Abrasion resistance

● Erosion resistance

● Clearance stability

● Precision-ground surfaces

● WC-Co or WC-Ni options
