Traditional insulation materials like rock wool, glass wool, or even high-end aerogel blankets share a common physical limitation: they are not fluid. When wrapping a reactor with a spiral-coil , blankets leave significant triangular gaps in the grooves.
These gaps lead to two major failures:
Convection Heat Loss: Air trapped in the grooves creates micro-convection currents, which can reduce the insulation's theoretical efficiency by 25-40%.
The CUI Trap: Moisture inevitably finds its way into these gaps. Because the surface is hidden, Corrosion Under Insulation (CUI) thrives undetected, leading to structural risks and high maintenance costs.
As demonstrated in our recent site applications (Image 2), Aerogel Thermal Insulation Coating is not just "paint"; it is a liquid-applied insulation system that transforms into a monolithic thermal barrier.
Why it's a game-changer for 2026 industrial standards:
100% Surface Integration: The coating flows into every spiral groove, eliminating air pockets and convection loops entirely.
Active CUI Prevention: By bonding directly to the metal substrate, it leaves no room for water accumulation. Its hydrophobic yet breathable nature keeps the reactor skin dry.
Space & Weight Efficiency: Achieve the same thermal performance as bulky blankets with only a fraction of the thickness. This is crucial for dense refinery environments where space is at a premium.
Simplified Maintenance: No need to strip off bulky blankets for inspection. The smooth coating surface allows for easy NDT (Non-Destructive Testing) and visual checks.
Our aerogel coating can be applied via spray or roller, making it ideal for the "irregularities" of chemical plants.
Thermal Conductivity: Maintains a stable low λ value even under thermal cycling.
Safety: A1-grade non-combustible material, ensuring maximum fire safety for volatile chemical environments.
Durability: Unlike fibers that settle or degrade over time, our coating resists mechanical vibrations and harsh weather.
In an era of rising energy costs and strict Carbon Peak goals, the "good enough" approach of wrapping reactors is failing. For equipment with complex geometries, switching to a seamless aerogel coating isn't just a choice—it's an investment in 25+ years of operational integrity.
