DODGED THE DIGITAL DILEMMA

The shift from analog to digital technology has given a new lease of life for NDT applications in the industrial radiography market, thus, broadening the scope beyond traditional applications. Digital X-ray systems are proliferating with increased acceptance across all industry verticals, including highly regulated and traditionally conservative aerospace and automotive industries. The most significant contributing factor for this paradigm shift to digital X-ray systems is the cost-saving, which is 5-6 times more (in both computed and direct radiography) when compared to film-based systems. The shift is also being fuelled by the bridge of gap by digital systems when it comes to high-resolution images, which used to be a niche for film radiography. Megatrends, such as Industry 4.0, Industrial Internet of Things, and Big Data, are expected to progressively phase out radiography on film.

ADVENT OF PORTABLE RADIOGRAPHY EQUIPMENT

The industry is experiencing significant influx of portable equipment in the recent years. With the need for inspection activities to be carried out at multiple locations and in various orientations, the industry demand for portable testing devices is increasing. The demand for compact and lightweight devices, which enable easier examination, has been a key trend in the market. Innovation in manufacturing technologies is propelling the deployment of these products. Elimination of installation costs with the use of portable devices, which helps in reducing the total cost of ownership (TCO) of these devices, is further helping the manufacturers strengthen their economic position in the market. The oil & gas industry, which employs testing across the industry supply chain for gauging the structural integrity and for continuous monitoring of intricate structures of various sizes, like plates, tubes and drilling machines, is expected to be among the most dominant end-users for portable radiographic equipment.

DIRECT RADIOGRAPHY TO BE THE GROWTH ENGINE

What’s leading the pack in digital radiography? Direct radiography is the fastest growing type of radiography with near double-digit growth rate as compared to the overall market. This segment is aided by advancements in hardware, such as tubes, sources, and detectors, as well as software improvements facilitating better user-friendliness and efficiency. The advantages of direct radiography, including shorter exposure times, real-time applications, use of recognition software, reduced inspection time, environmental concerns, portability, and increased dynamic range (enabling multiple thicknesses to be inspected in one shot), are driving their adoption across all industry verticals. Direct radiography equipment is offering guaranteed high ROI to customers, which is the biggest contributing factor for their growth. Significant market opportunity for direct radiography (includes real-time) exists in automotive and aerospace segments, which are witnessing very high growth rates, even exceeding that of the overall direct radiography market.
