FINDLAY, OHIO - Pipe extruder Hancor Inc. announced it can produce 60-inch diameter corrugated polyethylene pipe - its largest drainage pipe yet. The Findlay company did not say when full production will begin, but some of the pipe now is being installed at several demonstration projects.
Hancor said a staff of 15 engineers spent more than a year designing and building the machinery from scratch.
The big corrugated pipe is annular. That means each of the raised rings forms a closed circle, all the way around the pipe. The black pipe has a smooth wall inside.
Hancor said that the 60-inch pipe will be offered in 20-foot lengths.
Ultimately, Hancor plans to add the new pipe to its proprietary Hi-Q Sure-Lok product line, products that are watertight and silt-tight.
The Sure-Lok system features Hancor's Hi-Q pipe with a new gasketed integral bell design, which allows lengths of pipe to snap-fit together.
The bell has four self-locking cleats, eliminating the need for glue, couplers or wire ties, Hancor said.
