ABSTRACT:
A high temperature pre-insulated piping system is shown which has a special water stop located along the length of the piping. The water stop has an internal disk which forms a pair of isolated regions within the water stop. The internal disk is formed of a material which is impervious to the flow of water. As a result, the two internal regions are isolated from one another and act as isolating elements to contain any breach in the exterior of the piping system to a specific location in the length of the pipe string.
