DUAL-CONTAINMENT PIPE CONTAINING FLUOROPOLYMER

摘要

A dual-containment pipe includes a primary pipe and a secondary pipe having an inner peripheral surface that radially supports an outer peripheral surface of the primary pipe with an interstice formed therebetween. The secondary pipe contains fluoropolymer. The primary pipe has a mono-layered structure of static dissipative fluoropolymer, a multi- layered structure with static dissipative fluoropolymer at its innermost layer, or a multi- layered structure with static dissipative PA at its innermost layer and a fluoropolymer layer.
