One of the most innovative projects Aberfoyle has ever undertaken was to bend the pipe that forms the main span of a pedestrian bridge spanning the Humber River in Toronto, Canada.

Under tightly-controlled temperatures, a series of weights and specially-designed supports were strategically placed along each length of pipe to precisely bend 28 individual sections. Each of the pipe sections measured 26 feet long, 48 inches in diameter and varied from .75 to 1 inch wall thickness.

Furnace #1 was used for this undertaking because of the large amount of space that was needed for the setup of this heat treating job.

The main supports of the Humber River pedestrian bridge in Toronto were bent into their parabolic shapes using furnace #1

The pipes were bent using carefully-controlled application of weights along the length of the pipes during heating.
