After non-destructive pipeline In-line Inspections (ILI) are completed, numerous further ditch tests follow. These ditch tests are used to validate and refine the ILI findings. The top left image shows an IRISNDT inspector performing Ultrasonic testing (UT) to verify and refine the ILI depth assessment of an inside surface pit. The top right image shows one of the pits found (the
IRISNDT’s robotic inspection groups in Canada, the UK and the USA now deploy 3D localization. What does this mean? Inspection personnel create a 3D digital twin of the pressure vessel to be inspected before the inspection. Then, since the robot uses on-board laser and odometry data to accurately position itself, all NDT measurements and visual inspection pictures are
Figure caption – Carbon steel tube losses next to a heat exchanger baffle plate Baffle plates support tube bundles and direct fluid flow in heat exchangers. Vibrations from normal operating conditions can cause mechanical damage known as fretting (shown above); the losses result from continuous rubbing between the tubes and the baffle plates. How can we identify the
NFA INSPECTIONIRISNDT offers NFA tubular inspection services to inspect the ID of carbon steel fin-fan tubes. NFA tubular inspections use multiple individual coils grouped together instead of the single coil used in standard near-field testing (NFT). NFA uses two rows of receiver coils to provide 360º coverage of the ID of finned tubes. IRISNDT APPLIES NFA: To identify ID
Tanks are ubiquitous and essential in industrial societies. When they fail, the consequences can be dire if products/volumes they store are explosive and/or toxic. IRISNDT is pleased to have their Chief Engineer, Ana Benz, relate some “Tank Tales” in the July|August 2019 issue of the respected magazine “Inspectioneering Journal.” Topics cover the challenges in welding drain nozzles,repairing tanks, and inspecting
A great turn-out and even better proceeds for the Alberta Pressure Vessel Manufacturers’ Association (APVMA) 26th Golf Tournament at Innisfail on August 13th. The tournament supports Alberta’s children’s hospitals, and provides a fun experience for the pressure vessel industry to keep in touch. Bryan Cornforth, Paul Klammer, Lee Mackenzie, Paula Mueller, Nathan Pasemko, and Danielle Poles manned the IRISNDT sponsored
Figure caption: Inspecting a Sphere Using a Rope Access Adjustable Truss. IRISNDT’s Rope Access personnel installed a certified adjustable truss assembly inside a sphere to access and evaluate all the sphere welds. Along with the inspections, our personnel kept direct communication with Fitness for Service experts. They had to ensure the isolated areas were not ground below T min, and
Pipeline companies, companies that use tanks and pressure vessels, and inspection companies spend extensive effort and resources in finding where corrosion hides. They are dedicated to preventing leaks and failures. They train on identifying corrosion (see https://www.nace.org/about), on predicting where corrosion can happen, and on developing technologies looking for corrosion. Why go to these lengths? All the training and effort
