Abstract:
1. A casing for a conduit comprising: first and second encapsulated foam core sections that, when coupled, define a cylindrical void for receiving the conduit, wherein: each of the first and second encapsulated foam core sections have an interior surface that faces the conduit when the casing covers the conduit, an exterior surface that faces opposite the interior surface, and end surfaces; and each of the first and second encapsulated foam core sections are coated in a first layer of sprayable polyurea that substantially covers the interior surface, the exterior surface, and the end surfaces; a hinge, formed entirely of a second layer of sprayable polyurea that is bonded to: (i) the first layer of sprayable polyurea that coats the exterior surface of the first encapsulated foam core section, and (ii) the first layer of sprayable polyurea that coats the exterior surface of the second encapsulated foam core section, the hinge formed of the second layer of sprayable polyurea to couple the first and second encapsulated foam core sections; and a butt joint formed of sprayable polyurea, the butt joint extending beyond a first end surface of the first encapsulated foam core section and beyond a first end surface of the second encapsulated foam core section, the butt joint to receive an end surface of an additional casing and to provide a clamping surface for clamping the casing to the additional casing; wherein the hinge pivotably couples the first and second encapsulated foam core sections to allow the casing to removably cover the conduit.
