Specification of High Temperature 99%95% Alumina Ceramic Protective Tube

This alumina ceramic protective tube handles extreme heat and harsh conditions. It comes in two main purity grades: 99% and 95%. The 99% alumina version offers the highest performance. It withstands temperatures up to 1800°C (3272°F). The 95% alumina grade is strong too, handling temperatures near 1600°C (2912°F). Both grades resist sudden temperature changes well. They won’t crack easily from thermal shock.

These tubes are incredibly hard. They resist wear and abrasion effectively. Chemicals don’t damage them easily. Acids, alkalis, molten metals, and corrosive gases pose little threat. This makes them ideal for aggressive industrial settings. They are also excellent electrical insulators. This property is crucial in high-temperature electrical applications.

Standard outer diameters range from 4mm to 60mm. Wall thicknesses vary between 1mm and 10mm. Custom sizes are often available. Lengths typically go up to 2000mm. Shorter or longer pieces can be made. The exact dimensions depend on the application needs. The tubes feature a smooth, dense surface finish. This minimizes contamination and simplifies cleaning.

The primary job is protecting temperature sensors. Thermocouples and thermistors fit safely inside. The tube shields them from direct flame, hot gases, and corrosive materials. This ensures accurate temperature readings. These tubes also work well as furnace liners or process tubes. They guide materials through hot zones safely. They are found in kilns, metal processing, chemical plants, and lab equipment. The material provides reliable, long-lasting protection. It cuts down on maintenance and replacement costs.

Applications of High Temperature 99%95% Alumina Ceramic Protective Tube

High temperature 99% and 95% alumina ceramic protective tubes are vital parts in tough industrial settings. They handle extreme heat incredibly well. This makes them perfect for protecting sensitive sensors. Thermocouples and thermistors often need shielding inside furnaces or kilns. These tubes provide that essential barrier. They stop direct contact with corrosive gases or molten materials. This protection ensures accurate temperature readings. Reliable data is crucial for controlling industrial processes effectively.

These tubes excel in demanding applications. Steel mills use them constantly. Glass manufacturing plants rely on them near molten glass. Semiconductor production requires them in high-purity environments. The high alumina content is key. It offers outstanding resistance to thermal shock. Sudden temperature changes won’t easily crack these tubes. Their chemical inertness is another major benefit. They resist attack from many acids, alkalis, and solvents. This durability significantly extends their usable life. Replacing sensor protection frequently is costly and disruptive.

The purity level matters for performance. The 99% alumina grade offers superior properties. It withstands even higher temperatures consistently. It provides better resistance to wear and aggressive chemicals. The 95% alumina grade is also very capable. It handles high temperatures reliably. It offers a good balance of performance and cost. Both grades maintain excellent electrical insulation. This prevents signal interference at high temperatures. Their mechanical strength remains stable under intense heat. This prevents bending or breaking under load.

These ceramic tubes are fundamental for safe, efficient operation. They shield critical temperature sensors reliably. This protection is essential in harsh conditions. Accurate process control depends on it. Reduced downtime and lower maintenance costs result. Industries needing precise, high-heat measurements find them indispensable.

5 FAQs of High Temperature 99%95% Alumina Ceramic Protective Tube

What is this ceramic tube made from?
This tube uses high-purity alumina ceramic. We offer two main grades: 99% alumina and 95% alumina. Both grades provide excellent performance. The 99% grade offers slightly better high-temperature strength and chemical resistance. The 95% grade is a very good, cost-effective choice for many demanding uses.

How hot can this tube handle?
These tubes withstand very high temperatures. The 99% alumina tube works reliably up to 1800°C (3272°F). The 95% alumina tube handles temperatures up to 1700°C (3092°F). This makes them perfect for protecting sensors like thermocouples in extreme heat.

Where is this protective tube used?
You find these tubes in industries needing precise temperature measurement under harsh conditions. Common places include metal foundries, heat treatment furnaces, glass manufacturing plants, and high-temperature chemical reactors. They shield temperature sensors from molten metal, intense flames, and corrosive gases.

Why pick alumina ceramic over metal tubes?
Alumina ceramic beats metal in several key areas. It handles much higher temperatures without melting or warping. It resists chemical corrosion far better. It provides excellent electrical insulation. It doesn’t react with most molten metals or slags. This means longer life and more reliable measurements in tough environments.

Can I get a custom size or shape?
Yes, custom sizes and shapes are possible. Standard tube diameters and lengths are available. We can also produce tubes to your exact specifications. This includes special diameters, unique lengths, specific wall thicknesses, or particular end configurations. Tell us your needs.
