Description of Ceramic Fiber Tube
Ceramic fiber tube is a high temperature resistant insulation material made of ceramic fiber, which has excellent heat resistance, thermal insulation and chemical stability. It is often used in the fields of high temperature pipeline insulation, heat treatment equipment, electric heating element protection, etc. Ceramic fiber tube is light in weight, low in thermal conductivity, does not contain asbestos, is easy to construct, and is an ideal energy-saving refractory material.

Application of Ceramic Fiber Tube
Ceramic fiber tubes are widely used in high-temperature pipe insulation in metallurgy, power, chemical industry, shipbuilding and other industries. They can effectively reduce heat loss and improve energy utilization. They are also used for sealing and insulation of heating element protection sleeves, high-temperature gas transmission pipes, heat treatment equipment and industrial furnaces. They have good thermal insulation, fireproof and corrosion resistance, and are ideal insulation materials in high-temperature environments.
