ABSTRACT:
An irrigation machine distribution pipeline is protected against corrosion by a plastic liner within a steel pipeline. Access openings are spaced along the pipeline and aligned with apertures in the plastic liner. The liner extends the full length of the pipeline. The outside diameter of the liner is sufficiently less than the inside diameter of the pipeline to allow the liner to slide into the pipeline during installation of the liner. A plurality of plastic outlet fittings extend through each access opening and aperture. Each outlet fitting is in sealing engagement with the plastic liner and provides fluid communication from the interior of the plastic liner through the aperture to the exterior of the pipeline. With this construction none of the steel components of the pipeline comes in direct contact with the water.
