초록

Methods and apparatus for improved containment, detection, and monitoring of leaks of piped substances in which piping systems are constructed of connections of flanged, plastic-lined concentric pipe segments, these segments each having an inner and outer shell with an annulus therebetween and an aperture connecting the annulus with the exterior flange face of the pipe segment. A connector is described which may be placed between pipe segments to be connected and which has annular resilient sealing members and inner plastic seals to provide seals at the ...
