Brief Introduction of Ceramic Fiber Tube

Strong Thermal Insulation
High Corrosion Resistance
Good Thermal Shock Resistance
Low Shrinkage
High Strength
Light Weight
Convenient Operating
Energy Saving

The raw material of ceramic fiber tube is aluminum silicate rubber cotton felt. Besides, it is made by mold processing, drying, curing and shaping like ceramic fiber rope. Kerui high temperature ceramic pipe has low thermal expansion properties while providing excellent thermal insulation. Furthermore, our ceramic fiber tubes are able to withstand high levels of compression, making them thermal shock resistant. In addition, Kerui high temperature ceramic pipe also has high dielectric properties and air tightness, providing better vacuum and environmental protection when used at extremely high temperatures.

The Main Uses of Kerui Ceramic Fiber Tube

The main material of ceramic insulation tube is ceramic fibers, which are usually made of high-temperature refractory materials such as alumina (Al2O3), silicon dioxide (SiO2) and silicon nitride (Si3N4). Therefore, it is ideal for use in high temperature environments. Below are its 5 main uses.

  • High temperature insulation: ceramic fiber and high temp ceramic blanket have good insulation properties and low thermal conductivity, so you can use it as an insulation layer for high temperature equipment. These equipment include high temperature furnaces, heat treatment furnaces, glass melting furnaces, etc. Ceramic tubing can effectively reduce heat conduction and loss in these applications and improve the energy utilization of the equipment.
  • High temperature pipeline transportation: because ceramic fiber sleeve has excellent high temperature resistance, you can use them for the transportation of high temperature gases, liquids and solids. We can use it in petrochemical, metallurgical and power industries. Moreover, Kerui ceramic fiber pipes can replace traditional metal pipes and are more stable and reliable in high temperature environments.
  • Corrosive media transportation: in fields such as chemical industry, metallurgy and battery manufacturing, many media are highly corrosive to metals. However, refractory tube can maintain stable performance in these harsh environments. As a result, this reduces pipe maintenance and replacement costs and increases equipment lifespan.
  • Optical fiber communication: You can use Kerui ceramic fiber pipe insulation to protect and support fiber optics. This prevents it from being damaged and squeezed by the external environment. Therefore, this helps to improve the stability and reliability of fiber optic communication systems.
  • Aerospace: in spacecraft such as aerospace vehicles, rockets and missiles, due to the particularity of the working environment, they require high temperature and corrosion resistant China refractory materials. Ceramic fiber pipe insulation can meet these requirements.
