| High Light | 300kV Directional X Ray Flaw Detector ，High Frequency DC X Ray Generator ，55mm Steel Penetration NDT Radiography | ||
55mm steel penetration • up to 30-minute exposures • 30kg tube head • DR-ready — built for global NDT inspection companies
Third-party NDT service providers win projects on throughput, field reliability and cost per radiograph. RD-G300D was designed on all three. Its high-frequency DC constant-voltage generator keeps output ripple within ±1%, producing stable 30-300kV exposures with short exposure times — fewer retakes, sharper films, faster job completion on site.
The directional tube head radiates a 45°±5° beam and penetrates 75mm of steel (600mm FFD, 5 min, density ≥1.5) — enough for girth welds, storage tank seams and pressure vessel joints. Each exposure can run up to 30 minutes with a built-in 4:1 work-rest manager and full over-temperature protection, so the unit watches its own duty cycle while your crew keeps working.
