Specification of 99% Alumina Tube Ceramic Tube / Ceramic Pipe

This alumina tube uses 99% pure aluminum oxide powder. We form this powder into tube shapes. Then we fire it at very high temperatures. This creates a strong ceramic material. The result is a tube with excellent properties.

These tubes handle extreme heat very well. They withstand temperatures up to 1700°C. They also resist sudden temperature changes. This makes them reliable in tough conditions. They won’t melt or warp easily.

The material is very hard. It resists wear and scratching. It lasts longer than many metals in abrasive settings. Its surface stays smooth. This is important for many industrial uses.

Alumina is a great electrical insulator. It blocks electric current even at high voltages. It also works well at high frequencies. This makes it perfect for electrical and electronic parts.

The tubes resist chemical attack. Most acids and alkalis don’t damage them. They also handle molten metals well. This chemical stability is key for labs and factories.

We make these tubes in many sizes. Different diameters and wall thicknesses are available. Custom lengths are possible too. The tubes are very straight. Their walls are uniform. This precision is important for consistent results.

You find these tubes in many places. Furnace liners use them. Thermocouple protection tubes use them. Semiconductor processing equipment uses them. Laser tubes use them. Insulators in high-voltage equipment use them. They insulate heating elements. They guide sensors. They handle molten materials.

These tubes offer reliability. They perform under stress. They last a long time. They are a practical solution for demanding technical applications needing high purity alumina.

Applications of 99% Alumina Tube Ceramic Tube / Ceramic Pipe

99% alumina ceramic tubes handle extreme heat and harsh conditions. They withstand temperatures over 1700°C. This makes them perfect for furnace linings, thermocouple protection tubes, and kiln furniture. They manage intense heat without breaking down. These tubes resist chemical attack. Acids and alkalis don’t damage them easily. This is crucial in chemical processing equipment and corrosive environments. They won’t contaminate sensitive materials. Their hardness protects against wear. Abrasive powders and gases flow through them without causing significant erosion. This extends part life in demanding settings.

The material offers excellent electrical insulation. High voltages don’t pass through it easily. You find alumina tubes as insulators in spark plugs, electrical feedthroughs, and high-power equipment. They prevent dangerous electrical shorts. Their smooth surface helps in semiconductor manufacturing. Wafers travel through them in cleanrooms. The tubes don’t shed particles or react with process gases. Precision is possible. Manufacturers can hold tight tolerances on dimensions. This matters for scientific instruments and analytical devices.

Alumina tubes handle sudden temperature changes. They don’t crack easily when heated or cooled quickly. This thermal shock resistance is vital for rapid heating processes. They are strong mechanically. They support weight and resist bending under load. This strength is needed in structural applications within furnaces. The material doesn’t absorb water. Humidity doesn’t affect its performance. This stability is important in many industrial processes. These tubes work well in vacuum systems. They don’t release gases that could ruin the vacuum. This is essential for thin-film coating and research.

They are used in laser technology. The tubes house laser components needing protection from heat and electrical interference. Foundries use them for molten metal handling. The tubes guide metal flow without reacting. Laboratories rely on them for sample containment. They hold samples safely during high-temperature analysis. The aerospace industry uses them in sensors. They protect sensors measuring extreme conditions in engines and airframes. Their reliability is proven across many fields.
