Operating under a joint venture with Albin Carlson & Co., Patrick Energy was awarded a design-build contract to replace the aging steam system and support infrastructure at the Soo Locks.

ThermaXX was contacted by Patrick Energy to provide removable-reusable insulation jackets for the pressure reducing valve (PRV) and steam trap stations. ThermaXX provided product samples and conducted an on-site survey of the steam system and prepared patterns for the construction of custom removable insulation covers.

The exposed piping was at a temperature of greater than 350°F and was a potential burn hazard. Maintenance workers could mistakenly lean up against or bump into one of the uninsulated steam components, causing possible severe burns. The insulation design reduced the touch temperature to less than 120°. The tight working space was a challenge for the insulation cover designers and certain components needed to be customized to shape adjacent pipes or walls.

The insulation jackets were constructed using Teflon on the inside of the jacket and a silicone impregnated fiberglass on the outside. With the threat of water and dampness, Pyrogel, a hydrophobic insulation, was used for the insulation material within the tunnels. A total of approximately 175 insulation jackets were manufactured and installed.

ThermaXX said the easy to install design afforded Patrick Energy the ability to install the jackets with their own personnel.
