Core Features and Advantages of the Product
Precise division of labor between the two models, each leveraging its strengths.
Developed independently as both an online roller‑type system and a laboratory benchtop model, the hardware architecture and software logic have been meticulously optimized—respectively—for continuous line‑level operation and for discrete, single‑unit sampling inspections.Customers no longer have to settle for a one-size-fits-all solution. The rack‑mount model ensures uninterrupted, long‑term operation, while the desktop version is ultra‑compact, ideal for laboratories or workshops with limited space. With clear options to choose from, you can avoid over‑specification or under‑performance, achieving the optimal balance between procurement cost and operational efficiency.Deeply rooted in small- and medium-diameter pipelines, our inspections directly address the industry’s most pressing challenges.
Specialized adaptations have been implemented to address the weld‑joint characteristics of small- and medium‑diameter pipelines, including optimized radiographic inspection layouts and refined image‑processing algorithms.It effectively mitigates imaging artifacts caused by the large curvature and varying wall thickness of small-diameter pipes, delivering significantly higher detection sensitivity for a wide range of typical weld defects—such as porosity, slag inclusions, lack of fusion, and cracks—than conventional equipment. Customers can obtain stable, reliable inspection results without the need for repeated parameter adjustments, thereby reducing the workload of film reviewers.Instant printing—say goodbye to the film era once and for all.
Equipped with mature digital X-ray imaging technology, it employs a digital detector as the imaging medium and eliminates all chemical processing steps throughout the entire workflow.Dramatically improved efficiency—images can be previewed within seconds after exposure, eliminating the tedious steps of darkroom processing, drying, and archiving. At the same time, this approach permanently reduces costs associated with film and chemical consumables, while completely eliminating the environmental burdens and wastewater‑treatment expenses linked to chemical waste disposal, resulting in a substantial overall reduction in operating costs.Outstanding imaging quality, enabling flexible multi-angle inspections.
The system maintains excellent image clarity and contrast under typical industrial inspection conditions, and it features adjustable inspection posture and X-ray beam orientation.It is compatible with various welding processes, including butt welds, corner welds, and plug welds, and is not constrained by the geometry of the pipe fittings. Its clear and stable imaging quality ensures consistent film interpretation across shifts and operators, reduces the rate of human error, and provides a reliable basis for quality arbitration.Radiation protection compliance—seamless deployment and implementation.
The machine’s radiation shielding design strictly complies with relevant national safety standards, and certain models feature an integrated protective structure, eliminating the need to construct additional heavy‑duty shielding walls.We have significantly streamlined the environmental impact assessment and safety assessment approval processes, thereby shortening the lead time from equipment delivery to production commissioning. At the same time, we ensure that operators’ annual radiation exposure remains below the safety threshold, reducing occupational health management risks for enterprises and enabling customers to use our solutions with confidence while enjoying hassle-free management.Data traceability enables quality management.
Raw images, evaluation records, and reports are all stored in digital format with dual backups—both locally and in the cloud—and support multi-dimensional retrieval by time, batch, employee ID, and other criteria.Establish a comprehensive quality record spanning from raw materials to finished products, enabling rapid retrieval of historical data for traceability and root-cause analysis in the event of quality disputes. Meanwhile, the long-term accumulation of inspection data provides robust empirical support for optimizing welding process parameters and analyzing defect rates, driving quality improvement from an “experience-based” approach toward a data-driven one.Flexible retrofitting of online models, seamlessly integrated into the production line.
The online roller‑type equipment features an open interface, enabling custom modifications to accommodate site‑specific conditions such as roller surface height, conveying direction, and workstation spacing.Without requiring customers to halt production for reconstruction or make substantial adjustments to their existing line layouts, a seamless upgrade can be achieved—from manual loading and unloading with spot inspections to fully automated in-line full‑inspection. The retrofitting process is short, minimizes disruption, and delivers rapid returns on investment.Solid application domain and robust industry validation.
It has been widely adopted in industries with mandatory nondestructive testing requirements, such as the inspection and supervision of special equipment, the manufacturing of oil and gas pipelines, and the production of plumbing and bathroom fittings.The equipment has undergone rigorous on-site evaluations in the aforementioned industries—such as continuous production shifts, high‑temperature and dusty environments, and applications involving piping materials of varying compositions—demonstrating proven operational stability and durability. When selecting equipment, customers can draw on established industry case studies, significantly reducing decision‑making risks compared to opting for entirely new brands or laboratory prototypes.
