Abstract:
1. An extruded pipe connectable to a pressurized fluid source via a first end of said pipe, the pipe comprising a second open end, and a drip-irrigation plug emitter whose circumferential extremity is in full contact with an inner circumference of the pipe, the second open end of the pipe being away from the emitter, the emitter being mounted entirely within the pipe during the extrusion process of the pipe, said emitter having an inlet in fluid communication with said first end of the pipe, a flow restricting path connected to the inlet, and a drip outlet connected to the flow restring path and directing fluid from the flow restricting path to the second open end of the pipe away from the emitter, said emitter plugging the pipe with respect to any fluid flow except for the flow through said flow-restricting path, wherein all fluid flowing through the pipe has to flow through the emitter and wherein all fluid which exits the pipe exits from the second open end of the pipe, the pipe having at least one additional plug emitter allowing to adjust the length of said flow-restricting path by cutting off the plug emitter which is closer to said second open end.
