THERMAL BLANKET DESIGN
LT450TT-HES (LT232C-TT-HES)
INTRODUCTION
CAD designed and CNC produced, Shannon Thermal Blankets are custom jackets designed to save energy, capture radiant heat, minimize insulation maintenance, and improve the surrounding work environment. Shannon GES Thermal Blankets are the high-quality engineered insulation system built to withstand extreme weather and environmental conditions. Blanket design is CUI: Corrosion Under Insulation Compliant, Hydrophobic, Water Resistant & Corrosion Resistant. Removable and Reusable.
Common Applications and Markets
Pumps, Piping, Valves, Flanges, Equipment, Tanks. Shannon GES provides custom fit jacket insulation for complex surface conditions that require service, inspection and repair, with a CUI hydrophobic insulation requirement. Industries include: Chemical and Petro Chemical Processing Plants.
Service Temperature: This design is to act as a Thermal Barrier with a maximum service temperature of 450˚F (232˚C).
Product Components:
The Inner & Outer Jacketing consists of a 16.5 oz/yd² (560 g/m²) PTFE Teflon® Impregnated Fiberglass Cloth. The Insulation Core consists of a double layer of plain needled fiberglass mat and Hydrophobic Supermat™ @ 9 pcf (176.2 kg/m3) Type “E” Fiber, encapsulated by the inner and outer jacketing, with a double sewn construction, producing a “Self-Contained system”. The Blanket Insulation System includes Integral Fasteners & ID Tagging.

* The above referenced Cold Face Surface Temperatures should be used as guidelines for blanket insulation thickness design.
* The Cold Face Surface Temperature of the blanket should approach surrounding ambient temperature conditions.
* The economic thickness of the blanket should consider blanket cost, thermal performance and blanket design constraints.
* Heat Loss Calculations are based on a 21.1˚ C (70˚ F) ambient temperature using a flat surface condition.
