    摘要: A double-containment thermoplastic pipe assembly is provided to prevent against potentially hazardous spills or leaks of chemicals and the like. The double-containment pipe assembly comprises a containment pipe and at least one carrier pipe disposed therein. The carrier pipe is retained in spaced relationship to the containment pipe by support clips with outwardly extending radially aligned legs. Restraint couplings may be disposed at selected locations along the double-containment pipe assembly. The restraint couplings include a carrier portion, a containment portion and a connecting portion extending therebetween. Double-containment pipe fittings also are provided to ensure complete double-containment protection throughout an entire double-containment pipe assembly.
