Abstract
A penetration seal and its installation method for use with a pipe extending through an opening, or penetration, in a vessel, such as a boiler, containing fluid. A first collar surrounds the pipe adjacent the vessel and is in fluid communication with the opening in the vessel. A second collar has a sleeve portion engaging the exterior of the pipe and is spaced from the first collar. An insulation pillow substantially surrounds the pipe and is connected to the first and second collars. An expansion sleeve substantially surrounds the insulation pillow and is connected to the first and second collars, wherein the sleeve portion of the second collar is configured to compressively engage the exterior surface of the pipe sufficiently to frictionally fix the second sleeve against movement relative to the pipe.
Claims12
A penetration seal for a pipe extending through an opening in a vessel containing fluid, the penetration seal comprising:
- a first collar configured for surrounding the pipe adjacent the vessel and for being in fluid communication with the opening in the vessel;
- a second collar having a sleeve portion configured for engaging the exterior of the pipe and being spaced from the first collar;
- at least one insulation pillow configured to substantially surround the pipe and configured to be connected to the first collar and to the second collar;
- at least one expansion sleeve substantially surrounding the at least one insulation pillow and configured to be connected to the first collar and to the second collar;
- at least one first ring member configured to attach the expansion sleeve to the first collar;
- and at least one second ring member configured to attach the expansion sleeve to the second collar, wherein the sleeve portion of the second collar is configured to compressively engage the exterior surface of the pipe sufficiently to frictionally fix the second collar against movement relative to the pipe.
An apparatus, comprising:
- a vessel configured for containing a heated fluid, the vessel defining an opening in fluid communication with the heated fluid;
- a pipe extending through the opening;
- a penetration seal configured for attachment to the pipe and to the vessel, the penetration seal comprising:
- a first collar configured for surrounding the pipe adjacent the vessel and for being in fluid communication with the opening in the vessel;
- a second collar having a sleeve portion configured for engaging the exterior of the pipe and being spaced from the first collar;
- at least one insulation pillow configured to substantially surround the pipe and configured to be connected to the first collar and to the second collar;
- at least one expansion sleeve substantially surrounding the at least one insulation pillow and configured to be connected to the first collar and to the second collar;
- at least one first ring member configured to attach the expansion sleeve to the first collar;
- and at least one second ring member configured to attach the expansion sleeve to the second collar, wherein the sleeve portion of the second collar is configured to compressively engage the exterior surface of the pipe sufficiently to frictionally fix the second collar against movement relative to the pipe.
