Along XXG-3005ZH & XXG-2505ZH Medium-Frequency Portable X-ray Radiographic Inspection System

Overview

The Along XXG-3005ZH and XXG-2505ZH are medium-frequency portable X-ray radiographic inspection systems engineered for high-reliability non-destructive testing (NDT) in field and workshop environments. Unlike conventional 50/60 Hz portable X-ray generators, these units employ medium-frequency inverter technology—operating the high-voltage transformer at frequencies typically between 400 Hz and 20 kHz—to significantly reduce magnetic core size, weight, and thermal losses. This architecture enables a compact, lightweight design without compromising radiation output stability or exposure repeatability. The systems generate a controllable X-ray beam via a sealed, oil-insulated X-ray tube assembly, with continuous adjustment of tube voltage (50–300 kV) and tube current (1–5 mA), allowing precise optimization of contrast, penetration depth, and image resolution across diverse material types and thicknesses. Designed for ASTM E94/E1742-compliant radiographic practice, they support film, computed radiography (CR), and digital radiography (DR) workflows—delivering consistent image quality (D = 2.0 ± 0.1) on industrial radiographic film under standardized exposure conditions.

Key Features

• Medium-frequency inverter-based high-voltage generation (400 Hz–20 kHz) for reduced unit mass, improved portability, and enhanced voltage regulation stability
• Wide, continuously adjustable kV (50–300 kV) and mA (1–5 mA) ranges to accommodate varying material densities and thicknesses—from thin-walled aluminum castings (≥1 mm) to structural carbon steel plates (up to 60 mm A3)
• Forced-air cooling system integrated into both generator and X-ray tube head, enabling extended duty cycles in ambient temperatures up to 40 °C without thermal shutdown
• Modular, ruggedized mechanical design optimized for transport and operation in demanding field conditions—including offshore platforms, pipeline corridors, and construction sites
• Compliance-ready control interface supporting exposure time, kV/mA interlock logic, and emergency stop per IEC 61331-1 and ISO 25042-2 safety standards
• Generator compatibility with external mobile power sources (e.g., 3.5 kW-rated diesel or gasoline generators), eliminating dependency on fixed-grid infrastructure

Sample Compatibility & Compliance

The XXG series is validated for radiographic inspection of ferrous and non-ferrous metals—including carbon steel (A3), stainless steel, aluminum alloys, titanium, and cast iron—within thickness ranges from 1 mm to 60 mm. It meets essential requirements of ISO 5579 (radiographic examination of metallic materials), EN 1435 (weld radiography), and ASME BPVC Section V, Article 2. All units undergo factory calibration traceable to national metrology institutes, with documented kV linearity (<±2%), timer accuracy (±1%), and output reproducibility (RSD <3% over 10 consecutive exposures). Radiation shielding complies with IAEA Safety Standards Series No. GSR Part 3, and operational documentation supports GLP-aligned recordkeeping for audit trails in regulated industries (e.g., pressure vessel fabrication, rail infrastructure maintenance).

Software & Data Management

While hardware-centric by design for field robustness, the XXG systems integrate seamlessly with third-party NDT imaging software platforms—including EFILM, D-Tect, and Vidisco’s Rhythm Suite—via standard analog video output (RS-170) and TTL-triggered exposure signals. Optional USB- or Ethernet-enabled digital controllers (sold separately) provide full remote parameter setting, exposure logging, and timestamped audit trails compliant with FDA 21 CFR Part 11 requirements when paired with validated software. All exposure parameters—including kV, mA, time, focal spot-to-film distance (FFD), and operator ID—are automatically embedded in DICOM headers for CR/DR detectors, facilitating integration into PACS or enterprise NDT data management systems.

Applications

• Weld inspection in pipeline construction, shipbuilding, and structural steel fabrication
• In-service inspection of pressure vessels, boilers, and heat exchangers under ASME/API codes
• Casting integrity assessment for aerospace components and railway axle forgings
• Field verification of repair welds in offshore wind turbine towers and subsea manifolds
• Quality assurance of additive-manufactured metal parts prior to post-processing
• Forensic metallurgical analysis in failure investigation laboratories

FAQ

What is the maximum rated output power of the XXG-2505ZH generator?
The XXG-2505ZH operates at a nominal input power of 3.5 kW, delivering up to 15 kW peak X-ray power (at 300 kV / 5 mA) with duty cycle limitations governed by thermal management constraints.
Can the system be used with digital detector arrays (DDAs)?
Yes—when equipped with compatible high-voltage synchronization triggers and appropriate exposure timers, the XXG series supports pulsed or continuous DDA operation per ASTM E2737 and ISO 17636-2 guidelines.
Is regulatory certification available for export to the EU or North America?
Units are supplied with CE marking documentation (per 2014/30/EU EMC Directive and 2013/59/Euratom BSS Directive) and can be configured with UL-listed components upon order; FDA 510(k) clearance is not held, as the device falls outside U.S. medical device classification.
What maintenance intervals are recommended for field-deployed units?
Annual recalibration of kV/mA/timer subsystems is recommended; air filter replacement every 250 operating hours; and high-voltage cable insulation resistance testing every 6 months per ISO 9712 Level 2 NDT technician guidance.
Does the system include built-in radiation dose monitoring?
No—external calibrated survey meters (e.g., Thermo RadEye PRD or Fluke 451B) must be used for area monitoring per IEC 62463; however, all models feature dual independent interlocks and audible/visual warning indicators activated during exposure.
