Rock wool pipe shell is an inorganic insulation material widely used for pipeline insulation in industrial and construction fields, especially suitable for medium to high temperature (≤600℃) conditions. The following provides a systematic analysis of the insulation performance of rock wool pipe shell from aspects such as material characteristics, insulation performance, influencing factors, applicable scenarios, and comparison with other materials.
Rock wool pipe insulation possesses comprehensive properties of reliability, safety, and cost-effectiveness in medium and high-temperature pipeline insulation. Although its insulation performance is slightly inferior to that of glass wool (at room temperature) or nanomaterials (at the high-end), it excels in fire resistance, temperature tolerance, and cost, making it a mainstream choice for industrial pipeline systems. The key lies in controlling moisture infiltration and standardizing construction to fully leverage its designed insulation performance. Analysis of core indicators for insulation performance of rock wool pipe shell
1. Thermal conductivity (λ)
Rock wool pipe insulation has good thermal insulation performance in the range from normal temperature to medium temperature;
The λ value is significantly influenced by density, fiber arrangement, shot content, and humidity;
According to the national standard (GB/T 11835), when the average temperature is 70℃, λ should be no more than 0.039 W/(m·K).
2. Relationship between thermal resistance (R) and insulation thickness
3. Surface heat transfer coefficient and comprehensive heat transfer
Key factors affecting insulation performance: temperature/water absorption, compression deformation, temperature rise, joint treatment;
