Hooper Welding

What Hooper Welding does

Hooper Welding Enterprises Limited (founded 1952, Oakville, Ontario) designs and manufactures heavy, custom-built pressure vessels, reactors, columns, heat exchangers, steam drums, and skid-packaged process equipment to ASME Section I, III, IV, and VIII (Div. 1 and Div. 2) codes, as well as CSA N285.0 for CANDU nuclear power plants. Its core technical foundation is heavy custom fabrication: in-house mechanical and thermal design engineering, plate rolling up to 8.25" thickness, submerged arc and electroslag strip-cladding welding across 376+ qualified WPS covering carbon, alloy, stainless, duplex, Hastelloy, Inconel, and Monel metallurgy, advanced NDE (Digital Radiography, TOFD, PAUT), and an 80,000+ sq ft footprint anchored by the HEVI waterfront facility in Hamilton with 150+ ton crane capacity and direct Great Lakes/Atlantic shipping access. Operations span two facilities (Oakville 57,000+ sq ft; Hamilton HEVI 25,000+ sq ft high bay, with 15 overhead cranes up to 150 tons and a 30'W x 30'H x 120'L PWHT furnace). The largest completed reactor was 1.35 million pounds for a US refinery.

The business model is project-based B2B custom fabrication sold via direct enterprise sales and through EPC contractors (Fluor, WorleyParsons, Jacobs, KBR, Amec Foster Wheeler). Pricing is quote-based with multi-year contract cadences; each project is unique and bid to specification. Customers are concentrated in oil & gas refining (Husky, Cenovus, Petro-Canada, Co-op Refinery, Gulf Coast Refinery, Kansas Refinery), chemicals/petrochemicals/fertilizers (Eastman, CF Industries), power and nuclear (Bruce Power, Ontario Power Generation, Mississippi Gasification Power Plant), and filtration (Pall Corporation, a long-standing skid-supply partner). End-markets include oil & gas, chemicals/petrochemicals/fertilizers, power & nuclear, gas processing, and food processing.

The company is privately held, family-founded, with no public listing and no disclosed external investment. Its competitive differentiation rests on certified nuclear-capable fabrication, the unique HEVI waterfront shipping logistics, broad international code coverage, and single-source responsibility from design through delivery. No consumer or SMB segments exist; revenue mechanics are anchored by large custom-project milestones tied to refinery turnarounds, plant construction, and nuclear refurbishment programs in North America.
