Removable insulated pipe jacket

Abstract

A prefabricated insulated pipe jacket comprising two interlocking semicircular sections, with each section consisting of a stainless steel exterior overlay cover, an inner body of insulation and an interior protective sheet, the overlay cover and interior protective sheet being secured together to either side of the insulation by a series of spaced retaining members carried by a connector strip providing a semi-closure for the insulation while maintaining a minimum heat transfer attachment between the cover and inner protective sheet.

Having thus described my invention, what I claim as new and desire to protect by Letters Patent is: 
     
       1. A prefabricated removable insulated pipe jacket consisting of two mating semicircular longitudinal sections with each section comprising a. a semicircular outer metallic cover,   b. a batt of insulation material conforming to the configuration of said cover and of a size less than said cover and positioned on the inner surface thereof exposing one end and edge of said cover,   c. an interior protective sheet over the entire inner surface of said batt of insulation,   d. .[.an elongated connector strip providing spaced flange members extending at right angles therefrom with said flanges being equal in length to the thickness of said batt of insulation,.].   .[.e..]. means .[.provided by said first-mentioned means for.]. .Iadd.embracing the edges of said batt of insulation .Iaddend.connecting said cover to said interior protective sheet to either side of said batt of insulation while providing a minimum of heat transfer contact between said cover and said interior sheet, .Iadd.   e. said means including an elongated connector strip providing spaced flange members extending at right angles therefrom with said flanges being equal in length to the thickness of said batt of insulation, .Iaddend.   f. said flange members providing tabs at the free ends thereof adapted to be connected to a confronting surface of said protective sheet when said connector strip is connected to a confronting surface of said cover,   g. and means for releasably securing the exposed longitudinal edge of two mating sections together to form a circular jacket for the pipe.   
     
     
       2. A prefabricated removable insulated pipe jacket as defined by claim 1 wherein said means for releasably securing the sections together to form a circular jacket comprise spring latch members carried adjacent the exposed longitudinal edge of said cover, with said latch member cooperating with a latch plate carried adjacent an underlying edge portion of a juxtapositioned mating section for securing the same together into said circular jacket. 
     
     
       3. A prefabricated removable insulated pipe jacket as defined by claim 1 further including a heat-resistant foil covering all of the edges of said insulating batt as well as said means embracing said edges so as to encapsulate said insulating batt.
