ABSTRACT:
A double-containment pipe fitting and system for joining sections of double-containment pipe includes an outer containment housing, an inner carrier housing, and a plurality of restraining devices. The containment housing has a plurality of open ends. Each open end is constructed to securely connect to an open end of a containment pipe. the carrier housing has a plulrality of open ends constructed and arranged for positioning within the containment housing. Each open end of the carrier housing is constructed to securely connect to an open end of a carrier pipe. One restraining device is provided for each open end of the containment housing. The restraining device securely fastens the carrier housing to the containment housing and thereby restrains expansion and contraction of the carrier pipe and containment pipe. The carrier pipe and containment pipe are otherwise unrestrained against expansion and contraction. The double containment pipe fitting and system is suitable for use with filament wound pipe and other large diameter pipe.
