Abstract
A flexible pipe and a method of producing it. The pipe has two tubular structures, internal and external, and a tubular axial blocking layer. The tubular blocking layer comprises two section wires each having a trapezoidal cross section. The trapezoidal cross section defines a base and two sloping lateral flanks. The base of one of the two section wires is oriented toward the internal tubular structure. The base of the other section wire is oriented in the opposite direction. The section wires are wound side by side forming contiguous coils. The internal tubular structure includes a wire having a wound structure to form transversely blocked coils. One of the two section wires is wound against said structure coils.
