Abstract

Pipe sections and methods for forming pipe sections are disclosed. A pipe section includes a hollow body formed from a metal material, the hollow body having an inner surface and an outer surface, the inner surface defining an interior. The pipe section further includes a barrier layer surrounding and bonded to the hollow body, the barrier layer having an inner surface and an outer surface. The barrier layer is formed from a continuous fiber reinforced thermoplastic material. Such pipe sections may be lightweight and flexible while exhibiting improved strength characteristics.
