FAQ
Q1: When should I choose silicon carbide instead of alumina ceramic?
A1: If your application involves high-speed abrasive particles, high temperature above 1000°C, or strong chemical corrosion, silicon carbide is usually the better choice. It offers longer service life and more stable performance in harsh conditions.
Q2: What is the service life of silicon carbide ceramic pipes?
A2: Service life depends on material type and working conditions. In most slurry conveying systems, silicon carbide ceramic pipes typically last 1.5–3 times longer than alumina ceramic liners and significantly longer than steel pipes.
Q3: Can silicon carbide ceramic components handle high temperatures?
A3: Yes. Silicon carbide ceramic components can operate continuously at temperatures up to 1200°C, making them suitable for spray cooling, thermal power, and high-temperature conveying applications.
Q4: Are silicon carbide ceramic pipes difficult to install?
A4:No. They can be manufactured with standard flanges, threaded connections, or welded steel shells. Installation is similar to conventional industrial pipelines.
Q5: Which industries commonly use silicon carbide ceramic liners?
A5:Silicon carbide liners are widely used in cement plants, mining, coal handling, thermal power plants, chemical processing, and steel industries where severe wear occurs.
Q6:Can you provide custom silicon carbide ceramic parts?
A6:Yes. Custom shapes such as ceramic elbows, cyclone liners, spray nozzles, and wear plates can be produced based on drawings or working conditions.
Q7: Is silicon carbide more expensive than alumina?
A7:Yes, the initial cost is higher. However, due to longer service life and reduced downtime, silicon carbide often results in lower total operating cost.
Q8: How do I choose the right thickness for the silicon carbide liner?
A8:The liner thickness depends on particle size, velocity, and operating time. Typically, a 10–25 mm thickness is recommended for heavy wear applications.
