Hydrophobic calcium silicate tube shell pipeline protection refractory material? Hydrophobic calcium silicate pipe shell is a high-performance, hard prefabricated pipeline insulation material that integrates efficient insulation, excellent hydrophobicity, high strength fire resistance, and high temperature resistance. It solves the industry pain points of traditional insulation materials being prone to failure and pipeline corrosion in humid environments, and is particularly suitable for the long-term, safe, and stable operation of high-temperature steam pipelines in humid or harsh industrial environments. It is the preferred material for key engineering projects that require reliability, durability, and safety. Hydrophobic calcium silicate pipe shell is particularly suitable for environments with strict requirements for moisture resistance, waterproofing, fire resistance, and high temperature resistance. Hydrophobic calcium silicate pipe shell is a high-performance refractory material specifically designed for high-temperature pipeline insulation, widely used in steam, hot oil, and exhaust pipe systems in industries such as power, metallurgy, chemical, and aluminum plants.
Compared with ordinary calcium silicate or other insulation materials, the advantages of hydrophobic calcium silicate pipe shells are highlighted in the comprehensive performance improvement brought by "hydrophobicity":
1. Excellent hydrophobic and moisture-proof performance (core advantage):
The hydrophobicity rate is usually ≥ 98%. This means that water droplets on the surface of the material are like lotus leaves, unable to infiltrate and penetrate.
It can effectively prevent insulation materials from becoming damp and ineffective in humid environments (such as underground pipe galleries, outdoors, coastal areas) or during construction due to rainwater and condensation.
Once insulation materials become damp, their thermal conductivity will sharply increase (insulation performance will significantly decrease), and water will intensify corrosion of pipelines (corrosion bend insulation, CUI). Hydrophobicity fundamentally solves this problem. 2. High temperature resistance and non flammability:
Wide temperature range for use, with a maximum operating temperature of up to 650 ° C or even higher (depending on the product grade), it belongs to non combustible materials (Class A fireproof), and has extremely high safety. Suitable for steam pipelines, high-temperature heat medium pipelines, etc. 3. Excellent insulation performance:
The thermal conductivity is low, usually around 0.045-0.055 W/(m · K) at an average temperature of 70 ° C, which can effectively reduce pipeline heat loss or cooling loss.
