Pulp & Paper Mill Inspection & Integrity

TechCorr provides inspection and integrity services to pulp and paper mills, selecting the right technology and personnel for each job to deliver reliable inspection results.

Our expertise covers equipment damage mechanisms and the effect of process changes on existing equipment. Pulp and paper operations involve high temperature, high pressure, corrosive environments, and high-speed rotating equipment, and maintenance shutdowns are critical to safe, economical operation. At those times our teams assess critical assets such as boilers, digesters, piping, tanks, pressure vessels, and rotating equipment.

Our project managers and engineers work alongside plant teams to build safe, cost-effective inspection plans. Our specialists integrate nondestructive testing crews with plant maintenance operations — whether the job needs an eddy current technician, on-site heat treat or stress relief, or a rope access technician for elevated work.

Alongside traditional nondestructive testing, we support mechanical integrity (PSM compliance), reliability engineering including vibration analysis and laser scanning, risk-based inspection, owner-user integrity management systems, project and turnaround NDT supervision, and audit services.
