Pumps are critical components in industries like 石油とガス, power generation, chemical processing, and marine operations.
A single leak can cause costly downtime, environmental risks, and safety hazards. To avoid these issues, mechanical seals must be durable and reliable.
Tungsten carbide seal rings are one of the most trusted solutions for leak-free pump operation. This article explains their properties, advantages, applications, and best practices for decision-makers.
Why Leak-Free Pump Operation Matters
Prevents fluid loss → Protects resources and reduces waste.
Maintains efficiency → Pumps perform better without pressure loss.
Reduces maintenance costs → Fewer failures mean fewer repairs.
Protects the environment → Prevents spills of hazardous materials.
Ensures safety → Avoids dangerous leaks near operators or equipment.
炭化タングステンシールリングの特性
炭化タングステンは、タングステンと炭素がコバルトまたはニッケルと結合した化合物です。その特性は以下のとおりです。
過激 硬度 → Resists wear from friction and particles.
高い圧縮強度 → Handles heavy loads without cracking.
耐腐食性 → Works well with chemicals, seawater, and oils.
熱安定性 → Maintains sealing performance under high heat.
寸法安定性 → Ensures precise sealing over long periods.
These properties help pumps stay leak-free under tough conditions.
コバルト結合タングステンカーバイドとニッケル結合タングステンカーバイド
1）コバルト結合炭化タングステン
Best for vibration-heavy or high-shock pumps.
Common in oilfield and mining operations.
2）ニッケル結合タングステンカーバイド
Superior corrosion resistance.
Ideal for chemical plants, marine pumps, and wastewater systems.
Choosing the right binder ensures long service life and reliable sealing.
