Abstract
Disclosed is a method for detecting a blowout in an irrigation pipe being formed by an extrusion manufacturing process. The irrigation pipe is extruded. Further a positive air pressure inside the irrigation pipe may be created by circulating air through the irrigation pipe during the extrusion manufacturing process. The irrigation pipe with positive air pressure is then fed into a tank, wherein the tank comprises a coolant liquid. Further at least one air bubble is trapped at a surface of the tank.
