Water resistant adjustable jackets for insulated pipe and pipe bends

摘要

An adjustable jacket for an insulated conduit is provided, the adjustable includes inner and outer surface, first and second axial ends, and first and second longitudinal ends that each extends between the first and second axial ends. The first and second longitudinal ends form a longitudinal seal, which includes an outer seal formed by a terminal edge of one of the first and second longitudinal ends in contact with the outer surface of the adjustable jacket, and an inner seal formed by a terminal edge of another one of the first and second longitudinal ends in contact with the inner surface of the adjustable jacket.
