Boiler System / Assembly Inspection

Up to 450kV energy source available.

Inspects large tubing assemblies, sub-assemblies, and related components.

Compounded, oblique, multi-angular views.

Analog or digital imaging applications.

 

A major inspection challenge facing the boiler industries is to examine welds in tubing and plate during the manufacturing, erection, and start-up stages. In the steam generation business, billions are lost annually due to downtime caused by leaks in a plant’s boiler tubes that is in commercial operation. In addition, the problems that are often incurred by OEM’s during the manufacturing and erection of the boiler often creates delays in the project, cost over-runs, and customer/OEM frustration.

X-ray inspection systems can reduce this problem and assist the OEM in meeting customer goals. VJ Inspection Systems has designed, built and supplied custom inspection systems for a wide variety of boiler system applications.

 

Machine Process:
A custom designed conveyor carries the sub-assemblies to the entry door of the inspection vault. The sub-assembly enters the x-ray chamber where an operator indexes the weld-joints, archives the data, and repeats the process checking for fatigue, cracks, and full penetration of the weld joints.

Pressure Vessel Inspection

pressure vessel

Pressure vessels hold gases or liquids at different pressures from the ambient pressure. In the industrial sector, pressure vessels are designed to operate safely at a specific pressure and temperature. A vessel that is inadequately designed to handle a high pressure constitutes a very significant safety hazard.The basic principle of radiographic examination of metallic objects to determine their structural integrity the same as in any other form of radiography. Holes, voids, and discontinuities decrease the attenuation of the x-ray and produce a greater exposure on the image.
