Specifications of High Purity Refractory Insulation 95% 99% Porous Hollow Alumina Ceramic Tube

High purity refractory insulation porous hollow alumina ceramic tubes can be found in 2 main grades. These grades are 95% and 99% alumina pureness. Both types supply outstanding thermal insulation for extreme warmth conditions. The hollow tube structure creates air pockets inside. These air pockets minimize heat transfer dramatically. This style likewise reduces the overall weight. It makes managing and installment less complicated.

The product holds up against temperature levels as much as 1800 ° C. It stands up to thermal shock well. Abrupt temperature adjustments will not fracture it easily. The permeable nature aids as well. Pores catch air and block warm circulation. This increases insulation efficiency. You get better power cost savings in high-temperature arrangements.

Dimensions vary to fit different commercial requirements. Usual dimensions consist of outer sizes from 10mm to 150mm. Wall surface thickness ranges between 3mm and 20mm. Sizes can get to 1000mm or more. Personalized sizes are possible. Simply offer certain demands.

Chemical security is one more key point. Alumina withstands acids and alkalis. It will not rust or deteriorate in harsh atmospheres. This makes sure lengthy life span. The high purity suggests less impurities. Less contamination occurs in sensitive procedures. The 99% quality is especially pure. It matches semiconductor or laboratory applications. The 95% grade benefits general industrial usage.

Mechanical strength continues to be strong in spite of porosity. The tubes manage modest pressure and vibration. They won’t fall down under typical tons. This toughness reduces substitute expenses.

Installment is simple. Televisions fit into furnace linings or kiln wall surfaces. They protect pipes or burner also. Thermal performance enhances immediately. Energy usage declines. Running expenses decrease.

These tubes are excellent for steel plants, glass factories, and ceramic kilns. They also offer in warmth therapy heaters and research laboratory equipment. Performance is reliable in time. Maintenance needs stay reduced.

5 FAQs of High Purity Refractory Insulation 95% 99% Porous Hollow Alumina Ceramic Tube

What is this hollow alumina tube?
This is a special ceramic tube made from very pure aluminum oxide. It has tiny holes throughout its structure. We offer two purity levels: 95% and 99%.

What is its main job?
Its main job is providing excellent heat insulation in very hot places. It stops heat from moving easily. This protects equipment and saves energy in high-temperature processes.

Why does purity matter so much?
Higher purity means better performance under extreme heat. The 99% tube handles much higher temperatures than the 95% tube. It also resists chemical damage better. It lasts longer in harsh conditions like furnaces or reactors.

How do the holes help?
The tiny holes trap air. Air is a poor heat conductor. This trapped air creates a strong barrier against heat flow. So, the tube insulates extremely well because of its porous structure.

Where is this tube typically used?
You find it in demanding industrial settings. Examples include furnace linings, thermocouple protection sheaths, and lab equipment. It’s vital in semiconductor manufacturing, heat treatment furnaces, and aerospace applications needing reliable high-temperature insulation.
