Premium Industrial Pipe Insulation Shells (Triple-Core System)

Match the Core to the Stress:
"In industrial thermal protection, the core material must match the thermal stress of the environment," says Ruibin. We don't sell a single product; we offer a "Triple-Core" System. Whether you need standard steam protection or extreme furnace insulation, we provide the exact shell for your engineering requirement.

Key Technical Data (Certified Benchmark):

  • Thermal Conductivity: ≤ 0.044 W/(m·K) (at 25°C) — High-efficiency heat retention.
  • Service Temperature: Up to 1000°C+ (Depending on Core Selection).
  • Corrosion Control: Low Chloride/Fluoride — Strictly meets JC/T 618-2019 to prevent pipe corrosion.
  • Hydrophobic Rate: ≥ 98% — Excellent moisture resistance for outdoor pipelines.
  • Fire Rating: Class A1 (Non-combustible).
  • Dimensions: Inner Diameter 18mm - 610mm; Thickness 30mm - 200mm.

The "Triple-Core" Selection Guide:

  1. Glass Wool Core: Best for HVAC & Cooling/Heating (Up to 450°C).
  2. Rock Wool Core: The Standard for Steam & Boilers (Up to 650°C).
  3. Aluminum Silicate Core: For Extreme Metallurgy & Furnaces (Up to 1000°C+).

Why This Matters for Your Project:

  • Zero Condensation: High hydrophobicity keeps pipes dry, critical for preventing CUI (Corrosion Under Insulation).
  • Cost-Effective Alternative: If Aerogel is over budget, our High-Density Rock Wool is the preferred bulk alternative.
  • Project Proven: Successfully deployed in Dubai Petrochemical Pipelines (300°C Steam), reducing surface temp to <50°C in high humidity.

💡 Ruibin's Tech Tip:
"Golden Rule: Do not over-compress during installation! A 15% reduction in thickness can degrade thermal performance by 15%. Just provide your pipe size (OD) and temperature, and my team will suggest the ideal density and core material within minutes."
