Specification of Al2o3 Insulated Rings Alumina Sealing Ring 99% Alumina Ceramic Flange Ring

Al2O3 insulated rings are made from 99% pure alumina ceramic. This material is very hard and strong. It resists wear extremely well. These rings handle extreme heat easily. They work fine in temperatures up to 1650°C. Sudden temperature changes don’t crack them. This is thermal shock resistance.

The rings are excellent electrical insulators. They don’t conduct electricity. This makes them safe for high-voltage uses. They also resist chemical attack well. Acids and alkalis won’t damage them easily. This ensures long life in harsh environments.

The rings have high mechanical strength. They resist breaking under pressure. Their surface is very smooth. This helps create a tight seal. The material doesn’t absorb moisture. Performance stays stable in wet conditions.

These alumina sealing rings are very dimensionally stable. They don’t change size much with heat. This is crucial for maintaining precise fits. They are ideal for sealing flanges. They work well in furnaces, kilns, and high-temperature reactors. They are common in semiconductor processing equipment. They are also used in power generation systems.

The rings provide reliable insulation and sealing. They separate metal parts electrically. They prevent gas or fluid leaks effectively. Their high purity (99% Al2O3) guarantees consistent performance. They offer a long service life. They reduce the need for frequent replacements. They are a dependable solution for demanding industrial applications.

Applications of Al2o3 Insulated Rings Alumina Sealing Ring 99% Alumina Ceramic Flange Ring

Al2O3 insulated rings are vital parts in tough jobs. These 99% alumina ceramic sealing rings handle extreme conditions. They work well in high heat and strong chemicals. Semiconductor makers use them constantly. They seal plasma chambers in etching machines. The alumina withstands the plasma attack. It keeps the process clean. It prevents dangerous leaks. Electrical power systems rely on these rings. They insulate high voltage parts inside circuit breakers. Alumina rings stop electrical leaks reliably. They survive high temperatures plastic parts cannot. They manage thermal shock better than other ceramics. Industrial furnaces need strong seals. Alumina flange rings seal furnace hot zones perfectly. They keep the heat inside. They resist very high temperatures without changing shape. This maintains a tight seal cycle after cycle. Analytical instruments demand precision. Alumina rings create perfect vacuum seals inside mass spectrometers. They prevent air leaks that ruin measurements. The smooth surface stops gas from escaping. The material stays stable under vacuum pressure. Alumina ceramic rings are chemically inert. Harsh solvents do not damage them. This makes them safe for chemical processing equipment. They seal pumps and valves handling acids and bases. Their hardness prevents wear. They last much longer than softer seals. This reduces downtime for replacements. The high purity level matters. 99% alumina means very few impurities. This prevents contamination in sensitive processes. It ensures consistent electrical insulation. The material does not conduct electricity. It provides excellent isolation. Alumina rings are electrically insulating. They are also very strong mechanically. They resist breaking under load. These properties are essential for safety. They prevent equipment failure. Engineers choose alumina for its reliability. It performs where other materials fail. It handles rapid temperature changes easily. This is crucial for many industrial processes.

5 FAQs of Al2o3 Insulated Rings Alumina Sealing Ring 99% Alumina Ceramic Flange Ring

People often ask about Al2O3 insulated rings, alumina sealing rings, or 99% alumina ceramic flange rings. Here are five common questions and answers.

What temperature can these alumina rings handle? Alumina ceramic rings handle very high heat. They work well continuously up to about 1600°C (2912°F). Short bursts might reach 1800°C (3272°F). This makes them perfect for furnaces, kilns, and high-heat machinery.

Are these rings resistant to chemicals? Yes, 99% alumina ceramic resists most chemicals very well. It handles strong acids and strong bases. It also resists molten metals. Avoid hydrofluoric acid and strong alkalis at high temperatures. These can damage the ceramic.

What pressure can these sealing rings take? Alumina ceramic rings are very strong. They handle high pressure. The exact pressure rating depends on the ring size and design. Always check the specific product data sheet. These rings are much stronger than plastic seals.

How do I install an alumina ceramic flange ring? Handle these rings carefully. Alumina is hard but brittle. Avoid sharp impacts. Ensure the mating surfaces are clean and smooth. Use even pressure when tightening bolts. Do not overtighten. Overtightening can crack the ceramic. Follow the manufacturer’s torque specifications.

Can I get custom sizes and shapes? Manufacturers usually offer custom sizes and shapes. Common shapes are rings, discs, and washers. Special shapes are possible. Provide exact dimensions and drawings. Ask about minimum order quantities. Lead times for custom parts are often longer.
