PRESSURE ARMOR WITH INTEGRAL ANTI-COLLAPSE LAYER

摘要

There is provided a flexible pipe, the flexible pipe including a fluid barrier layer, a first pressure armor layer, a second pressure armor layer, and an anti-collapse sheath disposed between the first and second pressure armor layers. The first pressure armor layer may include a metallic interlocked anti-extrusion and hoop strength layer. The second pressure armor may include a hoop strength layer having non-interlocked helical wraps. The second pressure armor layer may include composite helical wraps.
