CROSS-LAMINATED PIPE AND METHOD OF MANUFACTURING SAME
Abstract:
A pipe having a wall formed from a cross-laminated film, and a method of making such a pipe. The film is formed of first and second layers having respective first and second orientation directions, wherein an angle between each of the first and second orientation directions and a projection of a longitudinal axis of the pipe on the wall is selected to enhance the resistance of the pipe to circumferential and/or longitudinal strain due to internal fluid pressure. The angle between each of the first and second orientation directions and a projection of the axis on the wall may be substantially equal to the neutral bias angle. In some cases, the angle between each of the first and second orientation directions and the projection of the axis on the wall may be substantially equal to 59°±2°.
