Specification of High Temperature Ceramic Tube Alumina Ceramic Tubes for Furnace

Alumina ceramic tubes withstand very high furnace temperatures. These tubes are made from pure aluminum oxide. This material offers exceptional heat resistance. Alumina tubes handle temperatures easily over 1700°C. They maintain their strength even at these extreme levels. Thermal shock resistance is also very good. The tubes cope well with sudden temperature changes. This prevents cracking during rapid heating or cooling cycles. Their melting point is extremely high. This makes them perfect for demanding furnace applications.

Chemical stability is another key benefit. Alumina tubes resist attack from many corrosive substances. They work well in oxidizing and reducing atmospheres. Acids and bases generally do not harm them. This inertness protects furnace processes. It also ensures the tube itself lasts longer. The material is very hard and dense. This gives excellent mechanical strength. The tubes resist wear and abrasion effectively. Surface erosion is minimized.

Various sizes and shapes are available. Common forms include straight tubes and closed-end tubes. Standard diameters range from small to large. Wall thickness can be selected based on pressure needs. Custom dimensions are also possible. These tubes serve many furnace jobs. They are used as protective sheaths for thermocouples. They act as sample holders during heat treatment. They form liners for kilns and ovens. They guide sensors or instruments into hot zones. Their high purity avoids contaminating sensitive materials.

Applications of High Temperature Ceramic Tube Alumina Ceramic Tubes for Furnace

Alumina ceramic tubes handle extreme heat. They work well in furnaces. These tubes are made from aluminum oxide. This material is very strong. It resists high temperatures. It doesn’t crack easily from sudden temperature changes. Furnaces get very hot. Normal materials fail there. Alumina tubes stay strong.

One main job is protecting thermocouples. Thermocouples measure furnace temperature. The harsh heat and chemicals inside can damage them. An alumina tube shields the thermocouple. It keeps the sensor safe. This gives accurate temperature readings. You see them in kilns and heat treatment furnaces.

These tubes also move gases and liquids. Furnace processes often need special atmospheres. Inert gases like nitrogen or argon flow through these tubes. The tubes deliver the gas right where it’s needed inside the hot zone. Alumina doesn’t react with most gases. It keeps the gas pure. Liquid metal handling uses them too. They guide molten metal without contamination.

Another use is holding samples. Heat treatment requires placing parts inside the furnace. Alumina tubes make good sample holders or supports. They touch the hot parts directly. The tubes don’t melt or degrade. They keep the sample stable during heating. This is important for testing materials or processing small items.

Alumina tubes insulate electrical parts. Heating elements or wiring inside furnaces need protection. The tubes cover these components. They prevent electrical shorts. They also shield wires from heat damage. This makes furnace electrical systems last longer. Foundries and labs rely on this.

5 FAQs of High Temperature Ceramic Tube Alumina Ceramic Tubes for Furnace

What’s the highest temperature these ceramic tubes handle?
Alumina ceramic tubes withstand temperatures up to 1800°C. This is their key strength. They stay stable and strong at these extreme heats. Other materials often fail much earlier.

Can these tubes handle sudden temperature changes?
Yes, they offer good thermal shock resistance. The tubes won’t crack easily moving between hot and cold states. This makes them reliable for repeated furnace heating and cooling cycles. Avoid very rapid extreme changes though.

What makes these tubes so heat resistant?
High purity alumina is the main material. This special ceramic is naturally very stable under intense heat. It doesn’t melt or degrade easily. It keeps its shape and strength where metals fail.

How do I clean the tubes after use?
Gentle cleaning works best. Use a soft brush or compressed air to remove loose debris. For tougher residue, soak the tube in a mild acid or alkali solution. Avoid harsh mechanical scrubbing. It can damage the smooth surface.

How long do these alumina tubes typically last?
Lifespan depends heavily on usage conditions. Tubes used within their rated temperature and handled carefully last many furnace runs. Avoiding physical impacts and thermal extremes extends their service life significantly.
