View Details →Problems This Family Solves
- Steel or ceramic seals wear out quickly in abrasive or corrosive environments
- Seal rings that deform under pressure lose contact and cause leakage
- Standard ring sizes are not available for non-standard shaft or housing dimensions
- Rings with poor surface finish or internal defects lead to early seal failure
- Lack of consistent material properties across suppliers causes variation in service life
Who Buys These Parts
- Pump and valve manufacturers requiring wear-resistant sealing rings for slurry, oil, and chemical service
- Machinery makers integrating carbide rings into high-pressure or high-wear components
- Maintenance teams replacing failed seals in pumps and compressors with a known drawing
- Tooling and instrument builders needing durable rings for precision components
- Distributors sourcing repeatable, consistent sealing rings from a single source
Why These Parts Hold Up
- Pressed on imported equipment and sintered in over-pressure furnace for stable density and closed porosity
- Surface ground to tight tolerance for minimal clearance and superior sealing performance
- Grade selected based on fluid, pressure, and wear conditions, not sold as a one-size-fits-all material
- Addition of corrosion-resistant rare elements during processing improves durability in aggressive environments
- High strength and hardness prevent deformation under compression or impact
Typical Applications
- Sealing rings in centrifugal pumps handling abrasive slurries
- Step-type rings in high-pressure valve assemblies for petrochemical service
- Flat rings used in mechanical seals for chemical process pumps
- Wear-resistant rings in instrumentation and precision rotating components
- Custom-shaped rings made to drawing for non-standard sealing applications
Industries That Use Tungsten Carbide Rings
Pressed Sintered and Ground In House
Weighing In of Ingredients
Tungsten carbide powder and cobalt binder weighed to the grade formula.
Milling
Powders wet milled so the binder is evenly distributed through the mix.
Spray Drying
The slurry is spray dried into free-flowing granules that press consistently.
Testing
Granulate checked before it is committed to a press run.
Forming
Blanks pressed on imported presses from the mould for that part.
Sintering
Sintered at around 1450 degrees C in an over-pressure furnace to close porosity.
Machining
Ground and finished to the dimensions on the drawing.
Quality Control
Physical properties, shape and tolerance checked, then inspection photographs sent before delivery.
Tungsten Carbide Rings FAQ
Can you make rings to my own drawing?
Yes. OEM and ODM services are available for custom ring shapes, including flat (PH), step (TH), and other special geometries.
How long is the lead time?
Stock items ship 3-5 days after payment is received. Customised items are quoted with a stated lead time.
Which grade should I use for a chemical pump seal?
Send the fluid, temperature, pressure, and solids content. Grades like YG6, YG8, YG10, and YG15 are used based on wear and corrosion resistance needs.
Can I test a sample before ordering in bulk?
Yes. Samples are available for pre-testing. Provide the drawing and service conditions for a sample quote.
How are parts checked before shipping?
Physical properties, shape, and tolerance are inspected before shipping. Inspection photographs are sent to the buyer for confirmation before delivery.
Are you a manufacturer or a trading company?
A manufacturer in Zhuzhou, Hunan Province, China, producing tungsten carbide parts for over 15 years.
