As clients across the paper industry have discovered, it pays to partner with IIAPaper & Pulp Industry
Papermaking is a time-honored process that has evolved into one of the world’s largest industries.
Modern papermaking is a complex process that requires high temperatures and high-pressure equipment, which can put equipment at greater risk of corrosion and cracking. The good news? You can stop structural integrity issues in their tracks — and IIA can help.
We are the inspection experts, and a trusted partner to the paper and pulp industry. Clients turn to us for unmatched technical expertise and quick project turnaround to keep their paper and pulp mills running smoothly and reliably.
Our toolkit includes conventional and advanced non-destructive examination (NDE) to pinpoint and analyze cracks, corrosion, erosion and other damage in recovery boilers, piping systems, digesters, kilns — every corner of your plant. And our services don’t stop there. Our team is also experienced with the mechanical lift devices inside and outside the facility that support your operations.

Paper & Pulp Systems & Equipment Testing
We offer a variety of inspection methods to help your plant run more safely and efficiently. Here are just some of the ways IIA can be of assistance.
BOILERS
IIA is commonly called in to support boiler inspection work scopes during outage maintenance projects. Our specialties include thickness surveys to identify corrosion rates on a variety of boilers (recovery, power, package, etc.) and associated equipment. Our technicians will identify areas that require repair by a welding contractor prior to returning your equipment to operation.
ABOVE-GROUND STORAGE TANKS
We are equipped and certified to perform API 653-compliant above-ground tank inspections. Our proprietary robotic AIRIS® tool can deploy via most tank manways. With our state-of-the-art equipment, we can even inspect tanks while they are fully operational.
PRESSURE VESSELS
Our certified API 510 pressure vessel inspectors perform internal and external inspections in addition to performing non-destructive testing. We have the capability to perform fully automated state-of-the-art PAUT techniques for vessel shell welds, nozzle-to-shell welds, nozzle-to-safe end dissimilar metal (DM) welds, and on safe end-to-pipe, as well as elbow welds.
PIPING
From water and gas piping to process and high-energy piping, we provide API 570-compliant piping examinations using a variety of complementary NDE; pulsed eddy current testing, guided wave testing, automated robotic systems, weld examinations, and more.
PAPER MACHINES
We frequently provide support for paper machine outages. Our technicians are skilled and efficient in providing internal visual inspections and bolt testing on paper machine dryer cans.
LIFT EQUIPMENT
Our team is also experienced with the mechanical lift devices inside and outside the facility that support your operations. For decades, IIA has provided on-site inspections and certifications to ensure the safety of overhead cranes and other aerial and lift devices. Our crane engineers can also assist with engineered weld repairs.
BOILER TUBE SAMPLE TESTING
As a full-service provider, IIA’s field inspections are backed by laboratory support across North America. Our labs can provide quick turnaround on metallurgical evaluations of tube samples collected during outages.
REMOTE VISUAL INSPECTION (RVI)
Our explosion-proof cameras can navigate tanks, tubes, vessels and pipes with ease — from access points as small as one-quarter inch in diameter. Our toolkit includes pan tilt and zoom cameras that ensure a thorough inspection of tanks, tubes, vessels, and pipes.
Other Systems & Equipment
When making maintenance decisions, the paper and pulp industry also turns to IIA for non-destructive evaluations of the following equipment and more:
- Digesters & Blow Lines
- Evaporators
- Concentrators
- Fans
- Heat Exchangers
- Lime Kiln
- Turbine

PULSED EDDY CURRENT TESTING
Pulsed eddy current testing is frequently used to measure the thickness of ducts and piping without the need to remove the lagging and insulation.
GUIDED WAVE TESTING
Utilized for pinpointing areas of further examination on uninsulated pipe sections, our guided wave testing experts are highly skilled at understanding the data.
OTHER TESTING METHODS
Our toolkit also includes versatile automated robotic systems and equipment for general weld examination, corrosion detection, mapping, pitting and wall-loss, PDI and general weld examinations, and screening and monitoring of casings.
