Pulsed Eddy Current (CUI) in Surrey, BC

CUI is external corrosion on insulated piping and vessels, fed by moisture trapped against the steel — invisible until the jacket comes off or the wall fails. It is among the most expensive integrity threats in process industries precisely because finding it traditionally meant stripping and reinstating insulation on spec.

Pulsed eddy current induces a decaying electromagnetic field in the steel through the non-conductive insulation and thin jacket; the decay rate corresponds to remaining average wall thickness. It reads through up to 100 mm of lift-off on 3–18 mm carbon steel walls — screening data with zero removal.

No — it is the screening layer. PEC grades relative wall loss through cladding fast; direct UT then quantifies the graded spots through small inspection windows. The pairing typically cuts insulation removal budgets by an order of magnitude versus strip-and-inspect.

Aluminum and stainless weather jackets over standard insulations are the designed use case. Thick galvanized jackets reduce sensitivity and get flagged at scoping. The aerial platform adds the part rope teams hate: elevated insulated lines and vessel tops without scaffolding.

Yes — our pilots hold Transport Canada RPAS certification with advanced-operations capability, and Surrey operations run under whatever airspace authorizations the location requires. BC's fastest-growing skyline plus huge warehouse parks — large flat roofs dominate the aerial workload. Flight planning, NOTAM checks, and authorizations are part of the service, not your problem.

Aerial inspection flies in defined weather windows — wind, precipitation, and (for thermal work) the right temperature differentials. Surrey sits in our standing Metro Vancouver coverage, so we schedule against the local forecast and typically land the survey within days of booking rather than weeks. Mon–Sat, 8am–6pm Pacific.

Province-wide pricing — no regional premium for Surrey. Single-asset thermal surveys typically start in the high hundreds; NDT campaigns and multi-asset programs are quoted by scope. The free phone consult (604-239-9934) produces a firm number in about five minutes.
