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.
Claims21
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;
- the moisture protective coating comprises at least one polyethylene layer and a polysurlyn layer;
- the exterior surface comprises a protective film adhered to the exterior surface by an adhesive;
- the adhesive comprises a medium tack adhesive that provides for toolless removal of the protective film;
- and
- the first metal shell is produced by applying the protective film to the exterior surface before form pressing or punch molding the first metal shell into a shape configured to follow contours of the pipe.
