Product Description

Heat Insulation calcium silicate pipe cover is an asbestos-free thermal insulation product that can withstand continuous operating temperature up to 1000. It is light weight, low thermal conductivity, high strength, easy to install, reliable and durable.
There are 2 grades available namely 650C & 1000 which are commonly used as furnace backup insulation in steel, petrochemical, ceramic, cement & glass industry or fire protection in building construction. It not only provides energy saving, also increases production efficiency and gives personnel protection in industrial safety aspect.

Product Characteristic:
1. Light weight, Low thermal conductivity
2. High bending and compressive strength.
3. Long service life
4. Good durability, no pulverization with long time use
5. Strong practicability in construction. Easy to process and install.
6. It is safe in use and non-toxic, non hazardous substances.
7. Protect equipment and don't corrode pipe.
8. Excellent chemistry stability.

Application:
1 Crude oil pipeline
2 Steel pipe insulation
3 Steam thermal insulation
4 Duct heat insulation
5 Gas pipeline insulation
6 All kinds of channel heat insulation

Calcium silicate board main content: MgO 0.1%, SiO2 47%, CaO 45% and other content. Calcium silicate board was mixed it an slurry blending tank, then pay-off to the reaction still after .
