Xuanming Industrial High Temperature Rock Wool has four perfect characteristics: strong high temperature resistance, good hydrophobicity, high corrosion resistance, and low thermal conductivity. It can provide the highest level of protection for boilers, furnaces, distillation towers, valve bodies, pipelines and other equipment in petrochemical, power plant and other industrial production to resist heat and energy loss, avoid fire, noise and other harmful effects.
Xuanming high-temperature rock wool pipe shell is particularly suitable for energy conservation in cold and hot pipelines, playing an important role in maintaining constant temperature, protecting personal safety, preventing condensation, and reducing noise. This product is rolled using a mold and fits tightly with the pipeline. The outer surface is polished to achieve precise insulation thickness.
Xuanming uses high-temperature rock wool that complies with domestic and international standards such as GB11835, GB50264, DL/T5072, SH3010, ASTM C612, and JIS A9504, meeting all performance testing requirements.
