Overview

The energy and power generation sectors demand robust, high-precision components built to withstand extreme conditions. Pearson supports this industry through a hybrid fulfillment model—offering precision machining, welding, and assembly either in-house or through our trusted Canadian partner network.

Whether produced at our Ontario facility or by certified suppliers, we manage quoting, coordination, and inspection so every part meets the reliability standards required for turbines, generators, heat exchangers, and renewable systems.

Capabilities We Provide Access To

  • Large-diameter CNC turning & horizontal boring of shafts, discs, and housings
  • Precision welding & cladding (ASME-aligned) plus post-weld machining
  • Tube bending and end-forming for heat-exchanger bundles and manifolds
  • Grinding (surface/cylindrical), shot peening, and surface conditioning
  • Dynamic balancing of rotors/impellers with balance documentation
  • Fixture/tooling fabrication for wind, solar, and hydro installations

DFM & Compliance Guidance

  • Call out datum schemes for alignment (bearing bores, keyways) and specify runout at operating interfaces.
  • Provide press-fit/bearing fit classes (e.g., ISO) and surface finishes for sealing or bearing seats.
  • Include corrosion allowance and coating stack notes; mask critical bores/faces where needed.
  • For weldments, attach WPS/PQR requirements and weld symbols; define PWHT/heat input limits if applicable.
  • Balance requirements: specify grade/plane(s) and permissible trim methods; note trial-weight restrictions.
  • Request NDE scope (PT/MT/UT) and acceptance criteria up front to align routing and lead time.

Share your drawing/model, tolerance/runout targets, weld/NDE scope, and coating/packaging needs. We’ll confirm achievable specs and the best routing (in-house or partner) before kickoff.

Why Partner with Pearson?

  • Hybrid fulfillment for scale: in-house precision plus certified Canadian partners for large/long components
  • Compliance-ready documentation: MTRs, weld maps, NDE, balance sheets, and FAIRs under one QA umbrella
  • Reduced downtime: outage-friendly scheduling, expedited inspection, and fit-on-arrival focus
  • Lifecycle value: repair/rework paths to extend component life and reduce total cost
  • Single point of contact from RFQ through logistics and final inspection

Equipment Used In-House or by Our Partners

Depending on the project, components may be manufactured at our facility or by a certified supplier.

  • Large CNC lathes, vertical turning (by routing), and horizontal boring mills
  • Manual & robotic welding cells; cladding systems; positioners & rotators
  • Heat-exchanger tube benders and end-formers
  • Shot peening, stress-relief ovens (by routing), and surface treatment lines
  • Dynamic balancing stands with data capture
  • 3D laser scanners, CMMs, and portable metrology for alignment checks

Typical Applications

  • Steam/gas turbine shafts, rotor discs, and diaphragm components
  • Combustion liners, transition pieces, and wear-resistant inserts
  • Generator housings, end bells, and stator/rotor hardware
  • Heat-exchanger tube sheets, channel covers, and bundle hardware
  • Wind turbine flanges, hubs, and gearbox supports
  • Solar array mounts, tracker brackets, and heavy bases

FAQs

Is all manufacturing done in-house?

No. We operate a hybrid model. Some components are produced at our Ontario facility; larger or specialized work is fulfilled through certified Canadian partners. Pearson manages quoting, coordination, QA, and logistics end-to-end.

Do you follow ASME and API standards?

Yes. We and our partners align to applicable ASME/API requirements. Provide the code section, NDE scope, and acceptance criteria with the RFQ so we can route correctly.

How large of parts can you handle?

Via our network we support components up to ~1.8 m diameter and ~6 m length, depending on geometry and ops (turning, boring, balancing). Send your envelope for confirmation.

What documentation can you supply?

Typical packages include MTRs/CoC, weld maps with WPS/PQR, NDE reports, dimensional reports, balance sheets, and serialization/traceability labels. Start your energy quote — include code requirements, NDE scope, balance targets, and your outage dates.
