Pulp & Paper

Pulp and paper mills combine high-temperature steam generation, recovery boilers, large-volume digesters, chemical recovery vessels, and extensive coated steel infrastructure operating in chemically aggressive, humidity-rich environments. The principal integrity drivers — caustic and chloride attack, dew-point corrosion, fireside thermal damage, and CUI on steam piping — require coordinated inspection, NDE, and coating oversight. Vertix supports mill operators with ISO- and ASME-aligned pressure equipment inspection and targeted engineering analysis on recovery, bleach plant, and steam-and-power island assets.

Capabilities deployed:

• Fixed equipment inspections to ASME / API 510 / 570 / 653 and CSA B51
• National Board / NBIC inspection of recovery boilers and HRSG-equivalent assets
• PAUT, UT, MT, and PT to ISO and ASME standards on critical welds and pressure boundaries
• Welding inspection to ASME IX, AWS D1.1, and CSA W59 on mill structural and pressure welds
• NACE/AMPP coating inspection on tanks, structures, and effluent service
• RBI, FFS, and damage-mechanism analysis tailored to mill chemistry
