摘要
A reinforced thermoplastic pipe having a polymeric barrier layer formed about a longitudinal axis; at least one first non-metallic reinforcement layer configured to carry an internal pressure load surrounding the polymeric barrier layer; at least one second non-metallic reinforcement layer configured to carry an axial load surrounding the at least one first reinforcement layer; and a polymeric cover layer surrounding the at least one second reinforcement layer. At least one of the first or second reinforcement layers is braided. In some embodiments, the lay angles of the first and second reinforcement layers are selected to reduce the axial compression force in the pipe in a constrained application. In another embodiment, an interior helical metallic layer around which the polymeric barrier layer is formed, the interior layer being an interlocked metallic carcass, a flat helically wound strip or a helically wound wire.
