Pulp & Paper Mill Inspection & Integrity

TechCorr USA prides itself on our team of over 5000 skilled technicians, engineers, and managers, all dedicated to delivering top-notch solutions ensuring smooth and safe operations. With 40 years of experience, we specialize in selecting the right technology and personnel for each job, guaranteeing cost-effective, reliable inspection results.

Our expertise encompasses comprehensive knowledge of equipment damage mechanisms and the impact of process alterations on existing equipment. TechCorr USA's engineers have been esteemed technical leaders in TAPPI, actively engaged with the American Forest and Paper Association (AF&PA) and the Black Liquor Recovery Boiler Advisory Committee (BLRBAC) for over two decades. They have significantly contributed to many industry-standard TIPS published by the Corrosion and Materials Engineering Committee of TAPPI.

We are dedicated to providing innovative solutions aimed at preventing costly unplanned shutdowns. The pulp and paper industry involves harsh conditions — high temperature, high pressure, corrosive environments, and high-speed rotating equipment for wood-to-pulp-to-paper conversion. Maintenance shutdowns are crucial for efficient, safe, and economical operations. At these times, TechCorr USA's teamwork, knowledge, and efficiency play a pivotal role in assessing critical assets such as boilers, digesters, piping, tanks, pressure vessels, and rotating equipment.

Our project managers and engineers have extensive experience working with clients across numerous pulp and paper mills in North America. They seamlessly integrate with your team to devise safe, cost-effective, and efficient inspection plans. Recognizing the complexities of managing large projects with tight timelines, our specialists excel in integrating nondestructive testing crews with plant maintenance operations. Whether you need an experienced eddy current technician, corrosion engineer, heat treat or stress relief on site, or a rope access technician for elevated work, TechCorr USA ensures adherence to schedules while achieving quality and affordability.

In addition to a broad spectrum of traditional nondestructive testing services, TechCorr USA offers National Board certified inspectors and engineers. Our expertise spans mechanical integrity (compliance to PSM), reliability engineering (including vibration analysis and laser scanning), Risk Based Inspection (RBI), owner-user integrity management systems, project and turnaround nondestructive testing supervision, and audit services. Our engineers are leaders in welding, corrosion, Fitness for Service, Finite Element Analysis, failure analysis, and offshore quality assurance for the pulp and paper industry.
