  • Flexible non-bonded pipe which is used to produce a dynamic pressurised fluid transfer hose and, in particular, a mud hose for rotary oil drilling
    Patent number: 7530372
    Abstract: The invention relates to a non-bonded pipe which is used to produce a dynamic pressurized fluid transfer hose and, in particular, a mud hose for rotary oil drilling. The inventive pipe consists of the following elements from inside outwards: an inner polymer sheath, at least two crosswise-arranged reinforcing plies comprising a wire which is wound helically at opposing winding angles, A and B, which are close to the angle of equilibrium of 55°, having an average that is centered on a value close to the equilibrium angle value; and an outer polymer sheath. The pipe also comprises an anticreep layer which is made from at least one coil with contiguous edges of a strip with high mechanical properties. Moreover, the aforementioned winding angles, A and B, of the crosswise-arranged reinforcing plies are not equal.
