Abstract: A pipe (40) having a wall formed from a cross-laminated film(20), and a method of making such a pipe. The film is formed of first and second layers having respective first and second orientation directions (21, 22), 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°.

Abstract: An air relief valve for use with an irrigation pipe. The valve comprises a base attached to the wall of the pipe, a vent extending from the interior of the pipe to the exterior of the pipe, a shutoff mechanism, and a water level sensor disposed within the pipe. The vent has an inlet adapted to face the interior of the pipe and an outlet adapted to face the exterior of the pipe. The shutoff mechanism is pivotally articulated to the base between an opening position thereof wherein air can exit the pipe via the vent and a closing position thereof wherein air is prevented from exiting the pipe via the vent. The shutoff mechanism is responsive to the water level sensor to selectively pivot between the opening and the closing positions
