ABSTRACT:
A dual containment pipe system suitable for installation into an existing conduit includes an impervious containment pipe adapted to be installed as a primary containment pipe and a crush-resistant and flexible spacer element disposed about the entire external circumference of the primary containment pipe. The annular spacer is formed of a plurality of spaced apart and parallel substantially crush-resistant longitudinal members with a plurality of spaced apart parallel flexible connecting ribs bonded thereto. The longitudinal members form a uniform space when the containment pipe suitable for installation of leak detection systems including cables or based on measuring pressure differentials. The new impervious primary containment pipe may be cured in place, folded and formed, diameter reduced pipe, or any other pipe suitable for pipeline rehabilitation.
