Technician Checking Thickness of Piping Section Using Ultrasonic Testing
Importance of Regular Inspections
International Inspection offers an array of nondestructive evaluation (NDE) capabilities to clients with large structures, including comprehensive boiler inspection services. Such complex machinery needs regularly scheduled assessments to ensure they continue to work properly. If not located and addressed in a timely manner, small indications or malfunctions can compound into significant problems. Lost productivity, unplanned downtime, costly repairs, unsafe working conditions, and employee injury can result when a boiler is allowed to continue operating where an initially small defect can deteriorate into a major failure. Companies can avoid these negative consequences by seeking the services of qualified NDE inspection providers like ourselves.
Our Boiler Inspection Services
Our team of ASNT certified inspectors examine areas of interest for indications of mechanical- or corrosion-related damage or wear. They employ a variety of NDE methods to determine what problems the boiler currently suffers from, what steps must be taken to address existing issues, and how to best prevent future failures. International Inspection technicians methodically survey the various components — from furnace to steam drum and all the piping and tubing in between — for common issues. These experts then document the nature and location of any defects they find, allowing clients to use the information to perform preventive maintenance or repairs as necessary.
Inspectors employ a range of NDE methods to characterize the health of a boiler system. The types of testing they use include the following:
The first step of a proper boiler inspection is the visual assessment of its important components. International Inspection’s team of technicians are thoroughly experienced at searching for flaws in surface elements of machinery components. Always equipped with a camera to document evidence and sometimes aided by specialized image-capturing hardware like a borescope, these professionals locate indications of potential issues, such as corrosion on tube walls. The results of their observations can warrant more intensive nondestructive testing of problem areas beyond the original scope of their inspection to characterize the nature and severity of the defect.
Depending on the circumstances of the inspection, technicians may decide that it is relevant to perform liquid penetrant testing as well. This method can reveal surface-level inconsistencies ranging from porosity to cracks, allowing inspectors to recommend steps for maintenance and repair of compromised components. Penetrant testing is also used to verify the effectiveness of weld repairs in damaged tubes.
This method uses a handheld device that emits and receives sound waves to image a subject’s subsurface features. International Inspection technicians employ it for its versatility, as it can be used both to locate discontinuities (such as stringers, cracks, and delamination) and to measure the thickness of materials. In the context of a boiler inspection, the team predominantly uses it for this second reason — by scanning readings at various points along water walls, floor tubes, and other components they monitor loss of thickness due to corrosion to ensure the system maintains full functionality.
