Citylink Exhaust Stack

As can be seen from the pictures to your right, the exhaust stack was a large pipe fabrication especially designed to extract fumes from the Citylink tunnel.

A high percentage of welds in the stack had to be inspected to meet the high standards required for this design. Page Steel had to work with tolerances normally associated with engineering workshops. This did not pose a problem as certain systems had been put in place to accommodate this requirement, prior to shop drawings being produced.

Normally the length of pipe frames would have been difficult to maneuver, but were handled with ease in Page Steel's new workshop, which was purpose built for long and wide manufactured sections. To allow for the over length load to be steered around corners during transportation, a prime mover and a steerable bogey was used.

The finished paint system used on the stack was that of an automotive finish. This meant that any blemishes on the steel would show up. A great deal of time was spent visually inspecting all surfaces and making sure of a first class paint finish.

Page Steel also erected this project to the tight tolerances required to ensure the client’s mechanical equipment fit into the correct position.
