THERMAL BLANKET DESIGN

LT450TT-HS (LT232C-TT-HS)

INTRODUCTION

Shannon GES Thermal Blankets are a CAD designed/CNC produced, high quality engineered removable/reusable insulation system designed to retain radiant heat, minimize maintenance and improve the surrounding work environment. Shannon GES Thermal Blankets withstand extreme weather and environmental conditions. Blanket design is CUI: Corrosion Under Insulation Compliant, Hydrophobic, Water Resistant & Corrosion Resistant.

Common Applications and Markets
Valves, Flanges, Pumps, Piping, Equipment, Tanks. Complex surface conditions that require service, inspection and repair, with a CUI hydrophobic insulation requirement.  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 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.
