NDT & Inspection for Pulp & Paper

Pulp mills run wet, hot, chemical and continuous — a corrosion recipe that never takes a shift off. CIC provides NDT and inspection for Alberta's pulp and paper operations: thickness programs that track what the process is eating, shutdown inspection scopes, and the lab support that explains failures before they repeat.

Where Mills Use Us

  • Digesters and pressure vessels — shell thickness surveys, weld examination and API 510-logic inspection programs

  • Tanks and chests — floor and shell condition on stock, liquor and water storage

  • Steam and condensate systems — erosion-corrosion tracking at the elbows and reducers that thin first

  • Recovery area support — inspection scopes coordinated within your boiler program's requirements

  • Structural steel — galleries, supports and buildings in a warm, wet, chemical atmosphere

The Testing Methods Mills Buy Most

Wet, hot and chemical service makes the mill method list corrosion-heavy:

  • Vessel, tank and piping wall loss → UT thickness at CMLs — the staple method of mill integrity, trended year over year

  • Thinning that spreads → PAUT corrosion mapping over shells and floors where spot readings stop being enough

  • Stainless and duplex welds in chemical service → LPI for surface defects plus ferrite testing against spec windows

  • Alloy verification on upgrades and repairs → PMI, confirming the 316L is actually 316L before liquor touches it

  • Weld repairs on pressure parts → RT or UT acceptance, hardness verification after PWHT

  • Hidden corrosion on insulated lines → CUI screening at the mill's damp, heat-cycled worst offenders

Corrosion Is the Program, Not the Surprise

In a mill, the question is never whether the process is corroding equipment — it's how fast, and where first. Repeatable CML thickness programs turn that into corrosion rates and retirement dates your maintenance plan can budget around, with PAUT mapping deployed where spot readings show the thinning has spread.

Shutdown Windows, Respected

Mill maintenance shutdowns are short, expensive and fixed — inspection either delivers inside them or waits a year. CIC scopes mill work in advance and reports findings while access still exists, so repairs happen this shutdown, not next.
