<p>A method of forming spray nozzles along a fluid conduit includes forming a row of holes (76, 78) along a length of tubing (10), and then countersinking the holes. Portions (72, 74) of the tubing are then depressed inwardly, one around each hole, along an imaginary line (14) along the tubing outer surface that is parallel to the central tube axis and that passes over the holes. An apparatus for carrying out the method is also disclosed.</p> |
