ABSTRACT:
An extruded irrigation pipe connectable to a pressurized fluid source via a first end of the pipe, the pipe comprising drip-irrigation plug emitter mounted integrally therein during the extrusion process of the pipe. The plug emitter has an inlet in fluid communication with the first end of the pipe, a drip outlet in fluid communication with a second end of the pipe, and a flow-restricting path therebetween. The emitter plugs the pipe with respect to any fluid flow except for the flow through the flow-restricting path. The pipe is conveniently produced as a section of a continuous long pipe comprising a plurality of such sections and adapted for being cut into such sections.
