High-energy Radiographic Testing | Applus+ United States
INTRODUCTION
High-energy X-ray systems provide high-resolution inspection capabilities for heavy-wall casting sections. Large irregular objects that would take hours to radiograph with conventional gamma-isotope equipment take a matter of minutes using the high-energy method.
THE Applus+ SOLUTION
With its high-energy X-ray systems, Applus+ can provide fast, sharp, precise radiographs of cast steel or equivalent materials up to 28cm (11”) thick, with a material weight of up to 10 tonnes. Two per cent sensitivity can be demonstrated on material with a thickness of as little as 1.9cm (.75”).
 
Our Varian linear accelerators can image 15cm (6 inches) of cast steel on medium-grain film in five minutes, whereas a 100-curie Cobalt 60 source exposure would take 10 times longer for the same application.
 
2mm focal spot sizes allow for greater definition at shorter source-to-film distances, while a higher radiation intensity permits longer source-to-film distances, covering up to six 35cm x 43cm (14” x 17”) films in a single exposure.
 
With seven different high-energy systems (2 x 2MeV, 1 x 3MeV, 4 x 4MeV), Applus+ has the greatest high-energy, industrial X-ray service capacity in the US.
 
TARGET CUSTOMERS
Typical applications for high-energy X-ray systems include:
  • High-pressure steel valves for the oil and gas industry
  • Blade and vane segments for industrial gas turbines
  • Nickel alloy aircraft engine castings
  • Stainless steel aircraft engine castings
  • Cast blade hubs for wind turbines 
KEY CUSTOMER BENEFITS
Clients using Applus+ high-resolution radiography will benefit from:
  • A significant reduction in NDT inspection-cycle time – particularly in the case of large, irregular objects – and subsequent cost efficiencies
  • An environmentally friendly process, with no chemicals required
  • Reduced quantities of film scraps
  • Extremely high-quality results and analysis
