RD-2805A Portable X Ray Machine 280kVp 5mA SF6 NDT Flaw Detector for Field Weld Inspection
RD-2805A Portable Industrial X-Ray Flaw Detector
150–280 kVp | 5 mA | SF6 Gas Insulated | Field-Ready NDT Radiography System
Product Overview
The RD-2805A is a portable industrial X-ray flaw detector engineered for on-site radiographic testing of welds, pipelines, pressure vessels and structural steel. It pairs a lightweight SF6 gas-insulated X-ray generator with an intelligent chopper-control console that delivers a stable 150–280 kVp output at 5 mA. Fully automatic conditioning, soft start / gradual shutdown and complete fault protection make it a dependable daily workhorse for third-party inspection companies and NDT service teams working in remote or harsh field environments.
| Why Inspection Companies Choose RD-2805A |
|
• True field portability – 26 kg generator + 9 kg controller, 4:1 work-to-rest cycle with up to 15-minute continuous exposure • Deep penetration – 45 mm A3 steel in 5 minutes, sensitivity better than 2% • Built for harsh sites – operates at −30°C to +40°C, ideal for desert, coastal and outdoor projects • Tube protection – automatic conditioning, soft start and gradual shutdown extend X-ray tube service life • Safety first – lead-door interlock terminals, radiation warning light output, over-temperature and discharge protection • Low maintenance – modular circuitry, detachable cooling fan, cumulative exposure-time recorder |
| Typical Applications |
|
• Third-party NDT / inspection service companies • Oil & gas pipeline and storage tank radiography • Petrochemical, refinery and desalination plant QA/QC • Pressure vessel and boiler weld examination • Power plant and infrastructure construction • Shipbuilding and offshore fabrication • Aerospace, defense and general weld inspection |
