Abstract:
1. A joint cover device comprising: an external joint cover comprising one or more layers of a polymer material, said external joint cover having loose edges, a watertight and vapor tight access seam formed from said loose edges, said external joint cover capable of completely enclosing and sealing in a watertight and water vapor tight manner at least one joint formed at the confluence of at least two pipes, said external joint cover capable of forming one or more interior areas around said joint, said access seam capable of permitting access to said joint protected by said external joint cover; a valve stem and a valve protection device formed of a rubber cup which fits around a base of said valve stem internal to said joint cover and a valve stem corrosion protection device which fits around a portion of said valve stem external to said joint cover and protects said valve stem; at least one securing structure per pipe capable of securing the ends of said external joint cover around each of the at least two pipes in a watertight manner, wherein said securing structure is a tape, a twist tie, a plastic cable tie, a metal cable tie, or a metal clamp, or any combination thereof that extends about said entire pipe; at least one non-external polymer joint cover located within said external joint cover and separated therefrom comprising either one or more volatile corrosion inhibitors therein or attached to an interior surface thereof or one or more volatile corrosion inhibiting capsules located within said one or more interior areas, or any combination thereof; and said one or more volatile corrosion inhibitors or capsules, capable of being transferred through said one or more interior areas to said joint and condensing thereon so that said joint is protected from corrosion.
