Abstract: A thermoformed PVC, modified PVC, CPVC, metal or coated metal cover, covering system and method is provided for covering assemblies of pipe and pipe insulation, hangers, support rods and mechanical assemblies wherein the assembly is biocide treated, covered by and completely enclosed by the cover, the cover is sealed in order to prevent bacteria growth within the cover while allowing a smooth outside surface for biocide application. The cover can be modified to facilitate the application of biocide after the assembly is covered by providing resealable openings in said cover.

Abstract: A tank head insulation cover comprising a plurality of generally wedge shaped panels with flanges, the panels being assembled in an overlapping manner onto the tank head so the flanges are in close relation to the perimeter of the tank. A center cap is provided to cover the area left uncovered by the panels.

Abstract: Protective covers for an exposed horizontally disposed P-shaped sink trap and for an exposed water supply valve for protecting a wheelchair bound person from burning when using the sink. Select embodiments of the P-shaped trap protective covers can be adjustably installed with P-shaped traps of varying size and which have been installed at varying angles, and select embodiments of the water supply valves can be installed with water supply valves of varying size.

Abstract: A process in which a blowing agent dispersion medium is used for producing poly(vinyl chloride) that is particularly well suited for use in insulation covers and the insulation covers made from the resultant poly(vinyl chloride).

Abstract: A one piece pipefitting cover for insulated Y-shaped joints, including strainers or lateral 45.degree.-Y fittings, made of a flexible material, i.e., polyvinyl chloride, comprising a relatively flat base symmetrical about its center axis having oppositely facing lateral members and semi-circular edge members along its sides wherein when rotated about its center axis forms a cover conforming to the shape of the insulated fitting.

Abstract: A flexible multilayer jacketing material for covering bare pipes or thermal insulation on pipes, etc., is a composite of an interior surface film of a metalized polyethylene terephthalate with its aluminum coated internal face bonded to one face of a central layer of glass fiber-reinforced asbestos paper which has its other face bonded to an exterior surface film of polyvinyl fluoride.

Abstract: As a flexible composite insulation, a layer of mass type of insulating material of low heat conductivity is bonded to a multilayer protective jacket. The mass insulation layer is flexible in at least one direction for fitting pipes, etc., and it is preferably a series of parallel contiguous strips of fiber glass or mineral wool batt insulation cemented to the vapor barrier layer of the jacket with their fibers substantially oriented in parallel planes aligned perpendicularly to the jacket. The jacketing material is preferably a combination of vapor barrier film of a metallized polyethylene terephthalate with its aluminum coated face bonded to one face of a layer of glass fiber-reinforced asbestos paper which has its other face bonded to an exterior surface film of polyvinyl fluoride.
