Methods and systems for jacket joints

Abstract

A system comprising a protective jacket for insulating pipe is provided. The protective jacket comprises a first metal shell comprising an interior surface and an exterior surface, wherein the interior surface comprises a moisture protective coating, and the exterior surface comprises a film adhered to the exterior surface by an adhesive, and wherein the adhesive provides for a toolless removal of the film.

1 . A system comprising:
 a protective jacket for insulating pipe, wherein the protective jacket comprises:
 a first metal shell comprising an interior surface and an exterior surface, wherein the interior surface comprises a moisture protective coating, and the exterior surface comprises a film adhered to the exterior surface by an adhesive, and wherein the adhesive provides for toolless removal of the film. 
   
     
     
         2 . The system of  claim 1 , wherein the first metal shell comprises a geometric shape having a fillet at a junction of one or more fingers. 
     
     
         3 . The system of  claim 1  wherein the first metal shell comprises an aluminum alloy, a stainless steel, a zinc, an aluzinc, a galvanized metal, or a combination thereof. 
     
     
         4 . The system of  claim 1 , wherein the moisture protective coating comprises a polysurlyn. 
     
     
         5 . The system of  claim 1 , wherein the film comprises a polyethylene, a polypropylene, a plastic, a vinyl, a polymer, or a combination thereof. 
     
     
         6 . The system of  claim 1 , wherein the adhesive comprises an acrylic adhesive, a water-based adhesive, a medium-tack adhesive, or a combination thereof. 
     
     
         7 . The system of  claim 1 , wherein the first metal shell comprises a first finger formed at least about 0.5 inches from a second finger to accommodate banding. 
     
     
         8 . The system of  claim 1 , comprising a second metal shell having substantially similar dimensions as the first metal shell, wherein the protective jacket comprises the first and the second metal shells fastened to each other. 
     
     
         9 . The system of  claim 8 , comprising a strap fastening the first metal shell to the second metal shell. 
     
     
         10 . The system of  claim 1 , wherein the protective jacket comprises an angled jacket, a tee junction jacket, or a combination thereof. 
     
     
         11 . A method for manufacturing a protective jacket for insulating pipe, the method comprising:
 manufacturing a first metal shell, wherein manufacturing the first metal shell comprises:
 applying a moisture protective coating to a first surface of a metal sheet; 
 applying a film to a second surface of the metal sheet using an adhesive, wherein the adhesive provides for toolless removal of the film; and 
 forming the metal sheet into a shape configured to follow contours of the pipe. 
   
     
     
         12 . The method of  claim 11 , wherein forming the metal sheet comprises disposing the metal sheet between a male mold having the shape and a female mold conforming to the male mold, and applying a pressure suitable to insert the male mold into the female mold. 
     
     
         13 . The method of  claim 11 , comprising manually removing the film before shipping the first metal shell, or manually removing the film after shipping the first metal shell. 
     
     
         14 . The method of  claim 11 , wherein forming the metal sheet comprises forming the metal sheet into an elbow joint shape having an angle of between approximately 45° and approximately 150°, or forming the metal sheet into a tee junction shape. 
     
     
         15 . The method of  claim 11 , comprising manufacturing a second metal shell having a substantially similar geometry as the first metal shell, and joining the first and second metal shells together. 
     
     
         16 . The method of  claim 15 , wherein the first and second metal shells overlap at a seam. 
     
     
         17 . The method of  claim 11 , wherein the film comprises a polyethylene, a polypropylene, a plastic, a vinyl, a polymer, or a combination thereof, and the adhesive comprises an acrylic adhesive, a water-based adhesive, a medium-tack adhesive, or a combination thereof. 
     
     
         18 . A method for manufacturing a protective jacket for insulating pipe, the method comprising:
 manufacturing a metal shell, wherein manufacturing the metal shell comprises:
 applying a moisture protective coating to a first surface of a metal sheet; 
 applying a film to a second surface of the metal sheet using an adhesive, wherein the adhesive provides for toolless removal of the film; and 
 using a male mold and a female mold to form the metal sheet into a shape configured to follow contours of the pipe by press or punch molding. 
   
     
     
         19 . The method of  claim 18 , comprising manually removing the film before shipping the metal shell, or manually removing the film after shipping the metal shell. 
     
     
         20 . The method of  claim 18 , wherein the film comprises a polyethylene, a polypropylene, a plastic, a vinyl, a polymer, or a combination thereof, and the adhesive comprises an acrylic adhesive, a water-based adhesive, a medium-tack adhesive, or a combination thereof.
