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
