A pipe feeder is a conveyor-based machine that applies continuous axial force to push large-diameter steel pipelines through pre-bored ground — without stopping, without friction spikes, and without open excavation. Unlike cylinder-based pushers that work in strokes, the UNI-PF250 uses a 4-track conveyor to maintain uninterrupted pipe movement across river, road, and railroad crossings from 20 to 56 inches in diameter.

The key difference between a conveyor pipe feeder and a cylinder pipe pusher is continuous vs stroke-based movement. Cylinder systems stop and reset every 3–10 feet, creating static friction spikes that stress the pipe and destabilize the bore. The UNI-PF250 conveyor system moves the pipe without interruption — eliminating spikes, protecting pipe integrity, and reducing installation time on crossings of 20–56 inch steel pipeline.
