HEAT EXCHANGERS & PROCESS COOLERS
The following images & videos were captured using various sizes of small diameter flexible video scopes and borescopes. Maverick uses inspection systems such as these flexible probes to access areas of interest through small openings and gather data in equipment internals and small piping. Video inspections on both the tube and shell sides of heat exchangers & process coolers include observations such as cleanliness, general conditions, corrosion, and erosion. These powerful imaging tools are often enhanced by measuring capabilities.
Remote Video Inspection (RVI) is the use of camera systems to image the internals of structures, equipment, and components that are otherwise inaccessible due to physical configurations, safety concerns, or other limitations. Maverick has a proven video inspection service track record including rapid response emergency services, working with our clients to plan RVI requirements for turnarounds, assisting in the development of predictive maintenance execution plans, and sourcing out or developing unique inspection technology.
EXCHANGER TUBE CLEANING DAMAGEThis video shows the aftermath of high pressure cleaning in a heat exchanger tube. An investigation found that the damage was the result of the incorrect use of a high-pressure cleaning tool. It was determined that surface wear and damage on the exchanger tube wall was created from the rotating tip of the 40,000 psi cleaning tool staying in one place too long. This inattention caused metal loss which created a small hole. The water streaming into the tube is from the pressurized shell side of the exchanger.
LUBE OIL COOLER BANK - FLOW TURBULATORS EXPOSEDPrior to start up after construction of the oil cooler, a robotic pan and tilt camera was used to verify that the turbulators were installed flush to the tube sheet.
The video shows the cooler bank flow turbulators protruding.
