Abstract
The flow conditioner for a gas transport pipe comprises at least one perforated plate disposed essentially perpendicularly to the axis XX' of the pipe and comprising a central hole and sets of additional holes that are regularly distributed over at least three concentric rings centered on the axis of the pipe so as to define a perforated plate that is axially symmetrical. Within any one ring all of the circular holes are of the same diameter d.sub.1, d.sub.2, d.sub.3. On going away from the central hole and on passing from any one ring to an adjacent concentric ring, the diameter of the holes changes alternately in a reduction direction and in an increase direction. Each ring has a number of holes that is equal to or greater than six. The perforated plate is advantageously associated with a porous plate situated upstream from the perforated plate and parallel thereto.
