ABSTRACT:
An insulation covering for the protection of cylindrical bodies exposed to high thermal and mechanical stresses is provided by the assembly of flexible resilient ring shaped insulation elements, the elements being comprised of fibrous refractory materials such as aluminum silicate, silica, alumina or glass. The insulation elements are assembled in a stacked array and are then compressed between rigid, or adjustable metal bands, to give a firm body of insulation which surrounds and protects the enclosed cylindrical body. One side of the ring shaped insulation elements may be severed to allow opening the insulation elements for installation around the cylindrical body, this modification being employed when the insulation elements cannot be placed over one of the ends of the body.
