Cemented Carbide Sealing Rings

Key Features:
1. Material Excellence
– Tungsten Carbide Substrate: Ultra-fine grain structure (0.4–1.5 µm) with 6–12% cobalt binder for optimal hardness (1,500–2,200 HV) and fracture toughness.
– Corrosion Resistance: Inert to acids, alkalis, seawater, and hydrocarbons, suitable for harsh chemical or marine environments.

2. Superior Performance
– Wear Resistance: Withstand abrasive particles, slurry, and high-friction conditions, outperforming steel or ceramic rings by 5–10x.
– Thermal Stability: Maintain dimensional integrity at temperatures from-50°C to +800°C.
– High-Pressure Tolerance: Operate reliably under pressures up to 1,500 bar (21,750 psi).

3. Precision Engineering
– Dimensional Accuracy: Tight tolerances (±0.005 mm) for perfect sealing surfaces.
– Surface Finish: Mirror-polished (Ra ≤0.4 µm) or ground finishes to minimize friction and prevent leakage.

4. Customization Options
– Coatings: TiN, DLC, or AlCrN coatings for enhanced wear resistance or reduced friction.
– Non-Standard Geometries: Custom inner/outer diameters (Ø5–500 mm), cross-sections, and groove designs.
– Material Grades: Adjustable cobalt content for tailored hardness-toughness balance.

Applications:
– Oil & Gas:
– Downhole tools, blowout preventers (BOPs), and valve seals in corrosive, high-pressure drilling environments.
– Chemical Processing:
– Reactor seals, pump shafts, and agitators handling acids or aggressive solvents.
– Aerospace:
– Hydraulic system seals, turbine engine components, and fuel injection systems.
– Power Generation:
– Seals for steam turbines, nuclear reactor coolant pumps, and geothermal equipment.
– Automotive:
– High-performance engine seals and transmission components. Advantages：
– Leak-Free Reliability: Precision-machined surfaces ensure zero leakage in critical systems.
– Extended Lifespan: 5–10x longer service life compared to stainless steel or ceramic rings.
– Reduced Downtime: Minimize maintenance and replacement costs in harsh operating conditions.
– Versatility: Compatible with oils, gases, chemicals, and high-speed rotating equipment.

Quality Assurance：
– ISO 9001 Certified: Full traceability of raw materials and production processes.
– Testing Protocols:
– Dimensional Checks: Laser scanning for roundness, concentricity, and surface finish.
– Mechanical Testing: Hardness, TRS, and fatigue resistance validation.
– Environmental Testing: Salt spray, thermal shock, and chemical resistance verification.

Customization & Logistics:
– Tailored Solutions: Collaborate with engineers to design rings for unique pressure, temperature, or chemical exposure requirements.
– Packaging: Anti-corrosion treated, individually wrapped in foam, or bulk-packed for industrial users.
– Lead Time: Standard sizes in stock; custom orders delivered in 4–8 weeks.
