1、 Product Overview
The insulation sleeve adopts a multi-layer composite structure, combined with precise 3D mapping and digital manufacturing technology, which can perfectly fit the surface of complex geometric shapes of equipment and effectively eliminate thermal bridging effects. Its detachable design greatly facilitates the daily inspection, maintenance, and emergency repair of equipment, significantly reducing downtime and operating costs. It is a key technical solution for achieving industrial high-temperature energy conservation and ensuring operational safety.
2、 Core technical parameters and material system
1. Extreme temperature resistance performance
The core of high-temperature equipment insulation sleeves lies in their ability to withstand ultra-high temperatures and long-term stability. The insulation materials and protective layers we use have undergone strict screening and testing to ensure excellent performance within the target temperature range
Applicable temperature range: 300 ℃ to 1200 ℃ (customized according to specific material combinations, up to 1200 ℃)
Long term use temperature: 1000 ℃ (Nano porous insulation board can withstand temperatures up to 1000 ℃ for a long time)
• Thermal conductivity: it remains extremely low under high temperature conditions. For example, the thermal conductivity of aerogel thermal insulation materials is equivalent to or even slightly better than that of nano powder matrix composite thermal insulation materials when the temperature is below 650 ℃.
