Power plants rely on cooling water systems to manage heat and keep turbines, pumps, and generators running safely.
Any leak or failure in these systems can lead to downtime, efficiency loss, or environmental damage.
Tungsten carbide seal rings are one of the most reliable materials for pumps and compressors in cooling water systems.
This article explains why they are essential, their benefits, and how to use them effectively.
Why Cooling Water Systems Need Reliable Seals
Prevent leaks → Protect equipment and reduce water loss.
Maintain efficiency → Proper seals help pumps operate at full performance.
Reduce downtime → Reliable seals minimize unplanned maintenance.
Avoid contamination → Prevents cooling water from mixing with other fluids.
Protect the environment → Stops harmful discharges into natural water sources.
Key Properties of Tungsten Carbide Seal Rings
Tungsten carbide is a compound of tungsten and carbon, bonded with cobalt or nickel. It offers:
코발트 결합 텅스텐 카바이드 vs 니켈 결합 텅스텐 카바이드
1) 코발트 결합 텅스텐 카바이드
보다 큰 강인함 for pumps exposed to vibration or shock.
Common in large turbine cooling systems.
2) 니켈 결합 텅스텐 카바이드
Superior corrosion resistance.
Ideal for brackish or chemically treated water.
