- Hardness rating HRA 89 to 92
- Threaded and curved flow ports
- Severe slurry erosion resistance
High-Speed TC Radial Downhole Bearings
Minjiang tungsten carbide radial bearings are developed for downhole mud motors and turbo drilling assemblies. Sintered carbide wear sleeves bonded to high-strength alloy bodies operate reliably with mud lubrication under severe downhole thermal conditions.
- Carbide hardness HRA 88 to 92
- High downhole thermal resistance
- PTA plasma arc hardfacing bond
- Rigid radial shaft stability
Lithium Battery Slitter Circular Blades
Minjiang ultra-fine grain tungsten carbide rotary slitter knives are precision-ground for continuous slit cutting of lithium battery electrode foils and separator films. Mirror-lapped cutting edges minimize friction, eliminating micro-burrs and edge dust.
- Mirror-lapped edge Ra < 0.05 um
- Slitting of anode & cathode foils
- Zero burrs and particulate shedding
- Extended continuous blade run life
Petroleum Pipe Thread Chasing Tools
Minjiang multi-tooth carbide thread chasers are engineered for high-precision threading of petroleum tubing and pipe connections under API Spec 5B standards. Rigid cutter profiles maintain thread pitch accuracy and uniform surface finish across large batches.
- Standard API Round and Buttress threads
- Multi-tooth profile for CNC lathes
- Hard PVD TiAlN wear coating
- Precision flank profile geometry
Tungsten Carbide CNC Indexable Inserts
Minjiang TT and CNMG series indexable carbide inserts deliver machining performance across alloy steels, cast iron, and high-temperature alloys. Engineered chipbreaker geometries reduce tool vibration and heat buildup during continuous cutting operations.
- Turning & milling lines TT & CNMG
- Advanced chipbreakers for alloys
- Wear-resistant grades YG8 & YG6X
- Thermal shock resistant coating
Carbide Bushings and Mechanical Seal Rings
Minjiang tungsten carbide bushings, pump shaft sleeves, and mechanical seal rings are utilized in industrial chemical pumps and oilfield fluid equipment. Nickel-binder alloy grades provide resistance against acidic slurry, alkaline fluids, and sour gas.
- Alloy grades YG8, YG11 and YN6
- Sour gas resistance against H2S & CO2
- Precision lapped flat faces Ra < 0.1
- Accurate diametral fit tolerances
Downhole PDC Thrust Bearing Assemblies
Minjiang downhole thrust bearing assemblies integrate polycrystalline diamond compact (PDC) inserts to absorb axial thrust loads in drilling motors. The superhard polycrystalline diamond layer delivers ultra-low frictional torque in heavy mud.
- Polycrystalline diamond PDC inserts
- Withstands severe axial drill thrust
- Raw drilling fluid lubrication
- Low frictional operating torque
Tungsten Carbide Rods and Tooling Blanks
Minjiang ground tungsten carbide solid rods and coolant-hole blanks serve as base stock for manufacturing solid carbide end mills, reamers, and drills. Homogeneous microstructures without porosity are achieved through vacuum sinter-HIP technology.
- Sub-micron grades YG6X and YG8
- Solid or helical coolant duct styles
- Precision centerless ground to h6 fit
- High transverse rupture strength
Manufacturing Standards of Chengdu Minjiang Cemented Carbide Tooling
Chengdu Minjiang Precision Cutting Tool Co., Ltd. operates a comprehensive production facility in Chengdu, integrating spray drying towers, automatic compacting presses, and vacuum sinter-HIP furnaces.
Stringent metallographic inspection and transverse rupture strength evaluations guarantee uniform grain distribution and zero microporosity across all sintered tungsten carbide tooling grades.
Heavy-Duty Wear Components for Downhole Drilling Equipment
Downhole positive displacement motors, rotary steerable systems, and drill bits encounter severe erosion from high-pressure drilling fluids. Minjiang TC radial bearings and tungsten carbide nozzles preserve flow geometry under harsh slurry abrasion.
PTA plasma transferred arc hardfacing bonds tungsten carbide tiles securely to alloy steel substrates, preventing delamination and extending drilling tool operating intervals in deep formations.
High-Precision Petroleum Pipe Thread Chasing Solutions
Minjiang multi-tooth tungsten carbide thread chasers are engineered for precision threading of petroleum tubing and pipe connections under API Spec 5B and premium connection specifications.
The multi-tooth profile distributes machining stock across cutting edges, minimizing cycle times on CNC lathes while maintaining thread profile accuracy and gas-tight sealing tolerances.
