High-Temperature UT in Chilliwack, BC

Wall-thickness measurement on hot, in-service assets — 0 to 260 °C (32–500 °F) — without shutdown, by drone. Echo-to-echo and pulsed-echo modes with live A-scan. Flown by Transport Canada-certified RPAS pilots serving Chilliwack and the Fraser Valley region — since 1999 as BC's leak detection and inspection specialists.

How the Chilliwack survey runs

  1. 1

    Thermal scoping

    Surface temperatures verified by radiometric camera before contact — probe selection and dwell strategy set accordingly.

  2. 2

    High-temp contact

    High-temperature delay-line probes and couplant rated for the surface take the readings; dwell time is managed automatically.

  3. 3

    Mode selection

    Echo-to-echo mode reads through coatings where present; pulsed-echo covers bare metal — A-scan verified live for every point.

  4. 4

    Condition report

    Readings mapped, trended, and delivered with the A-scan archive for the asset integrity file.

Chilliwack questions, answered

You can really measure a 250 °C surface without shutting it down?

Yes — that is the point of the service. High-temperature transducers with delay lines and rated couplant take contact readings on operating assets up to 260 °C. The drone removes the other half of the problem: nobody stands on hot steel at height to get the data.

What does avoiding a shutdown actually save?

Process interruptions are typically the largest line item in any inspection campaign — often dwarfing inspection fees entirely. On-stream thickness data also means integrity decisions happen on this year's numbers, not last turnaround's.

Does echo-to-echo mode work through paint?

Yes — echo-to-echo measures between back-wall echoes, subtracting the coating's contribution, so intact paint or thin coatings don't bias the wall reading. Thick or degraded coatings get flagged for our DFT or EMAT services instead.

Which industries use aerial high-temperature UT most?

Refining, petrochemical, power generation, pulp and paper, and district energy — anywhere assets run hot for months at a stretch and every offline hour is expensive. In BC that includes pulp mills, gas plants, and energy facilities across the Interior and North.

Can you legally fly drones for inspection in Chilliwack?

Yes — our pilots hold Transport Canada RPAS certification with advanced-operations capability, and Chilliwack operations run under whatever airspace authorizations the location requires. Agri-industrial corridor with large low-slope roofs and military-heritage buildings. Flight planning, NOTAM checks, and authorizations are part of the service, not your problem.

How does Chilliwack weather affect scheduling?

Aerial inspection flies in defined weather windows — wind, precipitation, and (for thermal work) the right temperature differentials. Chilliwack sits in our standing Fraser Valley 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.

What does high-temperature ut cost in Chilliwack?

Province-wide pricing — no regional premium for Chilliwack. 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.
