RD-3505 Portable Industrial X-Ray Flaw Detector
200–350 kVp | 5 mA | SF6 Gas Insulated | Thick-Section Field Radiography for Inspection Companies
Product Overview
The RD-3505 is a high-output portable industrial X-ray flaw detector designed for radiographic testing of heavy wall thicknesses on site. With 200–350 kVp tube voltage and 5 mA current, it penetrates up to 55 mm of A3 steel in 5 minutes, making it a first-choice workhorse for third-party inspection companies testing pipelines, storage tanks, pressure vessels and welded structures. The SF6 gas-insulated generator and intelligent chopper-control console deliver stable output, automatic conditioning and complete fault protection for demanding field programs.
| Built for CIS Inspection Programs |
|
• Heavy-wall capability – 350 kVp penetrates 55 mm steel for mainline pipelines, tanks and pressure vessels • Cold-climate operation – reliable from −30°C to +40°C for outdoor winter campaigns • Field-proven portability – generator 34 kg + controller <9 kg with 4:1 duty cycle, up to 15-minute continuous exposures • Uninterrupted supply – factory-direct availability with fast lead times for upgrading or expanding RT fleets • Full after-sales support – spare parts, exposure-curve guidance, remote troubleshooting and lifetime maintenance • Documentation – English manuals and certificates of conformity supplied with every unit |
| Key Highlights |
|
• 200–350 kVp / 5 mA with mA stability ±1% • Focal spot 2.5 × 2.5 mm; radiation range 40° ±5° • SF6 gas insulation, anode-grounded radiator with forced-air cooling • Intelligent MIXN control system, fully automatic conditioning • Soft start / gradual shutdown protect X-ray tube life • Safety door interlock, over-temperature, discharge and mA/voltage protection • Stepless kV and time knobs, delayed-exposure function • Cumulative exposure-time recorder for maintenance planning |
