Our team covers Sarnia

Sarnia and the wider Sarnia-Lambton area are part of our Hamilton team’s service area for scheduled maintenance, annual inspections and breakdowns. Trucks leave stocked with valves, pumps, controls and gaskets, so common parts arrive with the technician.

Industries in Sarnia

Sarnia industries that run on steam and hot water

Chemical Valley is one of Canada’s largest concentrations of refineries and petrochemical plants, and they are heavy steam users. Sarnia’s bio-industrial projects, its hospital and college, and the contractors who support the plants all run boilers as well.

Local considerations

TSSA inspections and lakeside conditions in Sarnia

In Ontario, boilers and pressure vessels fall under the Technical Standards and Safety Authority (TSSA). It administers the Boilers and Pressure Vessels regulation (O. Reg. 220/01), covering design registration, inspection and certificates of inspection, and the Operating Engineers regulation (O. Reg. 219/01), which licenses the people who run plants. We open boilers up and prepare them for the annual inspection.

Sarnia’s winters are milder than much of Ontario, with January design temperatures around -16 °C, but heating plants still run hard from fall to spring. Many faults start outside the boiler itself, so we also look at pumps, controls, piping and condensate return.
