650 D.C. Calcium Silicate Pipe Cover and Board

The 650 D.C. calcium silicate pipe cover & board are suitable for thermal insulation of piping and equipment in power station, steel mill and petrochemical industries as well as other various fields. It can also be specified to use in furnace as backing material of refractory bricks.

Properties of calcium silicate pipe and board:

High strength: the strongest one among the inorganic thermal insulation materials with the similar density;
Non-deformation within the temperature range;
Low thermal conductivity;
Long service life;
Asbestos-free.
