Ampy Pipe
1 / 5
Calcium silicate 220 is taking inorganic siliceous and calcareous as material and treated by special technology such as high temperature and high-pressure hydrothermal reaction. It has excellent performance under the temperature of 650ºC. The greatest advantage is it can provide nice protection to pipelines since it with super-low chloride ion content. Thanks to the improvement of producing technology, we have reduced the thermal conductivity from 0.065 to 0.049 at present.

Commonly applied in insulation projects such as: tank and tank base, pipeline, vessel, equipment, cryogenic ship, etc. for petroleum, chemical, refrigeration, underground projects, shipbuilding, national defense and residential construction industries. It can be applied in severe environments like: low & cryogenics / hot temperature, underground, outdoors, flammable, wet, and chemical etc.
