Pipe X-ray Inspection in the Petrochemical Industry


Vidisco’s cutting edge portable digital X-ray systems are widely used in the Oil and Gas industry - mostly in the downstream sector but also in the upstream sector (oil and gas wells) digital radiography technology delivers highly efficient solutions to inspection needs for pressure vessels (pipes, boilers, valves) according to international standards (ASME, API).


Pipe Radiography


Using Vidisco's DR systems during service operations and even in the manufacturing process offers immediate high quality, high contrast, X-ray images. Digital radiography can easily reveal not just corrosion and erosion but also precise measurement of pipes' wall thickness and weld quality. Technicians can continue using the same isotopes and industrial sources they have been using when shifting Vidisco’s portable DR systems.

Vidisco Systems Dramatically Reduce Exposure Times When Using Isotopes Energy

The following table provides a comparison of the duration of various types of pipe radiographic testing. The table compares inspection time that has been conducted with film and an IR-192 Isotope, compared to inspections in the same locations, but conducted with Vidisco's RayzorX Pro digital radiography system using the same Ir-192 source.
