Abstract

In a flexible tube for fluid transport, a resin layer is on the outer periphery of an interlocked tube for shielding the fluid flowing within the interlocked tube. An internal-pressure-resistant reinforcing layer is on the outer periphery of the resin layer for reinforcing primarily against internal pressure, etc. of the fluid flowing within the interlocked tube. An axial-force reinforcing layer is on the outer periphery of the internal-pressure-resistant reinforcing layer for primarily suppressing the interlocked tube from deforming in the axial direction of the flexible tube. The axial-force reinforcing layer is formed from alternately winding two layers of reinforcing strips with a long pitch. The reinforcing strips are each configured from a metal strip, a resin layer that covers the strip, and the like. The resin layer is resin to which a microparticulate sulfide-trapping material has been added.
