20080303273 | Irrigation Pipe Coupling - A coupling is formed from inner and outer members. The inner member is attached to a pipe wall and is formed with a bulge. The outer member is retained by the inner member and is formed with a clamp that surrounds the bulge. | 12-11-2008 |
20090065084 | CROSS-LAMINATED PIPE AND METHOD OF MANUFACTURING SAME - 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°. | 03-12-2009 |
20090211661 | Irrigation Pipe Connector - An irrigation pipe connector has a core that is adapted to connect to an irrigation element and a wing that is attachable to a wall of a pipe. The wing is provided with resiliency to allow the connector to deform in response to changing fluid pressures in the pipe. In addition, the wing may be provided with a thin segment in order to reduce potential damage during welding of the wing to the wall of the pipe. | 08-27-2009 |
20120247599 | Irrigation Pipe Connector - An irrigation pipe connector has a core that is adapted to connect to an irrigation element and a wing that is attachable to a wall of a pipe. The wing is provided with resiliency to allow the connector to deform in response to changing fluid pressures in the pipe. In addition, the wing may be provided with a thin segment in order to reduce potential damage during welding of the wing to the wall of the pipe. | 10-04-2012 |
20130257042 | Fitting Assembly Having Separate Seal and Barb Arrangement for Engaging A Flexible Pipe - A fitting assembly that can attach to an open end of a flexible pipe has a nipple and a clamp. For attachment, the pipe is fitted with its open end over the nipple and the clamp fits over the pipe where the pipe fits over the nipple. The nipple has a seal and a barb arrangement that is located rear to the seal. The seal and barb arrangement contact an inner face of the pipe. The clamp has an axial extension that is sized to overlie the barb arrangement and the seal in order to press the pipe against the barb arrangement and the seal. | 10-03-2013 |
