Abstract
ABSTRACT
A thermal blanket adapted to cover well-heads, blow-out preventors (BOPS's) and the like is provided.
The blanket comprises an insulating layer disposed between inner and outer environment proof layers.
Fasteners are provided at various locations about the blanket to secure the blanket to the device being covered. The environment proof layers are formed from polypropylene and are weather, oil and chemical resistant. The insulation layer is formed from asbestos. Since the insulation layer is shielded from the environment, the blanket exhibits a long lifetime and maintains good thermal properties. Heat tracing, steam lines and the like can be held by sleeves which may be formed on the inner polypropylene layer to allow a heat source to be applied to the well-head or blow-out preventor being covered.
