Abstract: A flexible pipe comprises an inner supporting pipe (1) made from an elastic material, onto which inner supporting pipe a shaped strip (2) is wound. Said strip (2) has a cross-section profile formed by two stepwise conjugated quadrangular flanges (3) and (4), the height of each of the flanges being equal to a half of the height of the profile. The adjacent turns of the strip (2) partially overlap each other so that the upper flange (3) of one turn is superimposed onto the lower flange (4) of the other flange, and the ends of the flanges (3) and (4) are aligned. An interlayer (5) made from an elastic material is superimposed onto the power frame formed by the strip (2). At least one pair of reinforcing layers (6) and (7) formed by groups of power filaments (8) and (9) is disposed on said interlayer (5), said filaments being parallel to one another and wound in contrary at angles of from 0.degree. to 20.degree. to the axis of the pipe.
