Selected work,
de-identified on request.

Most of our clients prefer not to publish project details. The case studies below describe scope, approach, and outcome, operator names withheld where required.

Plant operators rarely want their corrosion problems on a vendor website, and we respect that. Each case below is real, the engineering decisions described are real, and the outcome is documented in our records. Names are withheld where the contracting party preferred it; representative photography is used where the original installation cannot be photographed.

If you'd like a reference for a project similar to yours, we can usually arrange a direct conversation between operating teams.

01 — Featured Project

Selenium water treatment
tank system.

One of the largest global water treatment companies needed 30 large FRP tanks, plus an integrated raised platform system, engineered, fabricated, and delivered to California in under six months. NSF 61 compliance required throughout.

Challenge. Drought conditions in California forced groundwater to travel further to reach treatment facilities, absorbing elevated concentrations of selenium along the way. Selenium is essential in trace amounts but hazardous at high levels. The client needed 30 large FRP tanks, each 13 ft × 29 ft, plus an engineered raised FRP platform spanning the entire tank array, all within a six-month window. Every tank had to meet NSF 61 requirements for drinking water contact.

Approach. Precisioneering dedicated a full crew and a filament winder exclusively to this project. The tanks and the integrated raised FRP platform system were engineered concurrently to keep the schedule tight. All 30 vessels were hydrostatically tested and inspected before leaving the Ontario facility.

Outcome. The complete system, 30 tanks plus the platform, was shipped from Ontario to California ahead of schedule. Precisioneering's delivered price, including cross-continent transportation, was cost-competitive against every other North American FRP tank fabricator that quoted the work.

2,000 ft SOx/NOx hazardous scrubber ducting.

One of the largest global nickel producers needed a full replacement of the SOx/NOx scrubber ducting system at their smelting operation, in three months. The effluent is among the most toxic industrial gases encountered in FRP service; the surrounding city maintains active evacuation plans in the event the scrubber system is compromised. During inspection, a section of duct that had been power-washed and left open for over two weeks still required one inspector to seek medical treatment after exposure.

Standard polymer expansion joints could not withstand the corrosive duty. Precisioneering engineered a custom fiberglass bellows expansion joint purpose-built for the service conditions. Fabrication ran three dedicated stations, 24 hours a day, seven days a week for the full three-month window, and the project was completed on time.

Precisioneering was selected because the client needed absolute confidence that both the engineering and the fabrication schedule would hold. This was designated a critical-risk project; failure to deliver on time or to spec was not an option.

— Operator Feedback

Our previous vendor sold us tanks. Precisioneering sold us a chemistry decision and the tanks came with it. Three years in, we haven't had a service call.
