Product Description

Calcium silicate 220 is composed of inorganic siliceous and calcareous materials, treated via high-temperature and high-pressure hydrothermal reactions. This product has achieved ISO9001 certification and demonstrates excellent performance at temperatures up to 650ºC. Its primary advantage is providing superior protection to pipelines due to its exceptionally low chloride ion content. Through advanced production technology, the thermal conductivity has been optimized to 0.049.

Frequently Asked Questions

1. What is the maximum temperature resistance of your calcium silicate?
We offer two main series: the standard series supports up to 650ºC, and the high-temperature series can withstand up to 1000ºC.
2. Does the product contain asbestos?
No, our calcium silicate products are 100% asbestos-free, ensuring safety and hygiene for all industrial and residential applications.
3. Why is low chloride ion content important for pipelines?
Low chloride ion content prevents stress corrosion cracking in stainless steel and carbon steel pipelines, significantly extending the service life of the equipment.
4. Can these boards and pipes be used outdoors or underground?
Yes, they are designed for severe environments, including underground and outdoor industrial sites. They are treated to be waterproof and fireproof.
