Product Details
Aluminum silicate insulation pipe is a tubular insulation material made of aluminum silicate fiber as the main raw material through a special process. It has the characteristics of high temperature resistance, low thermal conductivity and light weight. According to the different alumina content, it can be divided into standard type, high purity type, high aluminum type and zirconium-containing type.

- Strong high temperature resistance: wide working temperature range (1000 - 1350℃), can be used for a long time in high temperature environment.
- Excellent thermal insulation effect: low thermal conductivity (such as only 0.09W/m·K at 400℃), can effectively reduce heat transfer.
- Lightweight and easy to install: low density (96 - 160kg/m³), reduce the load of pipelines, can be cut and wound during construction, and has strong adaptability.
- Good chemical stability: corrosion resistance, acid and alkali resistance, not easily corroded by high temperature flue gas or chemical media, long service life.
- Environmentally friendly and safe: does not release harmful substances, meets industrial environmental protection requirements, and has a certain tensile strength and is not easy to break.
- Industrial high-temperature pipelines: such as power plant steam pipelines, metallurgical industry heating furnace pipelines, chemical reactor pipelines, etc., used to block high-temperature heat loss.
- Building insulation: high-rise building heating pipelines, central air-conditioning insulation pipelines, reduce energy loss and reduce noise.
- Kiln and equipment insulation: glass kiln, heat treatment furnace exhaust pipes and high-temperature equipment outer covering to improve thermal efficiency.
