Making pipe: It all begins with plastic flakes

Making pipe for agricultural drainage is a multi-step process that begins with plastic flakes.

By: Mikkel Pates, Agweek

MOORHEAD, Minn. — Plastic flakes brought into the plant via rail car in Moorhead will come into a station inside the plant. This material goes into a hopper that in turn fills an extruder. The extruder melts the plastic and pushes the material through a die head appropriate to the diameter of the pipe — 4-inch, 6-inch, up to 15 inches at this location. (They make up to 60-inch at Prinsburg.)

The extruder pushes the plastic into a cone shape.

The corrugators use vacuums to pull it into the corrugated round pipe. The pipe goes through a water bath to make it “cool to the touch,” into a perforator, and, finally, into coilers.
