Division 22 23 Ebook Page 117 VaporWick® Pipe Insulation Product Data Sheet

Product Data Sheet VaporWick Pipe Insulation concept that utilizes a unique wicking material to remove condensed water from the system, keeping the insulation dry. Water vapor that enters the system and condenses on the cold pipe surface is removed to the outer surface by capillary action, where it then evaporates to the ambient air. Standards, Codes Compliance ASTM C547, Mineral Fiber Pre- Formed Pipe Insulation, Type 1 2 ASTM C795, Thermal Insulation for Use Over austenitic Stainless Steel 3 ASTM C585, Inner and Outer Diameters of Rigid Thermal Insulation for Pipe and Tubing Nuclear Regulatory Commission Guide 1.36, Non- Metallic Thermal Insulation 3 NFPA 90A NYC MEA No. 349-02M Thickness To Prevent Surface Condensation VaporWick Pipe Insulation does not prevent surface condensation. Sufficient thickness must be selected to minimize condensation on the outer surface. Use the following table for guidance. Fluid Temperature 35F Ambient Temp.
