Product Description

RD-3505 350kV Portable Industrial X-Ray Flaw Detector

High-Energy Radiography for Thick-Wall and Heavy-Section Weld Inspection
 
When weld quality cannot be compromised, the RD-3505 delivers. Built by Hangzhou Huiwei Nondestructive Testing Equipment Co., Ltd. (est. 1993), this SF6 gas-insulated portable X-ray flaw detector pushes a tube voltage of 200–350 kVp to penetrate up to 55 mm of A3 steel — making it the go-to choice for thick-wall pipelines, heavy steel structures and pressure vessels. Its dependable 4:1 automatic work/rest cycle keeps inspectors productive through long on-site shifts, so whether you are an end-user plant QC team or a third-party NDT inspection company, the RD-3505 gives you radiographic certainty where it matters most.

Product Features

  • 200–350 kVp high-energy tube for deep, high-contrast radiography of thick and dense materials.
  • Up to 55 mm A3 steel penetration (5 min exposure) — outstanding performance on heavy-section welds.
  • Image sensitivity better than 2% for reliable defect detection and code-compliant film quality.
  • SF6 gas insulation with anode-grounded aluminum heat sink and forced-air cooling for stable long-shift use.
  • Fully automatic 4:1 work/rest cycle with up to 15 minutes continuous exposure — built for inspection firms running consecutive jobs.
  • 3.0 × 3.0 mm focal spot and 40° ±5° radiation angle for efficient film coverage.
  • MIXN-series expert intelligent control system with high-strength anti-interference design for harsh field environments.
  • Fully automatic tube training mode with discharge auto step-down to protect X-ray tube life.
  • Complete protection suite: mA over/under, kV over/under, discharge auto-detection, over-temperature (HT) and safety-door interlock (SD).
  • Delayed exposure timer and automatic memory of last settings after power-off.
  • Field-service friendly: tool-free dust-cleanable cooling fan, rubber shock-corner housing, side status light, clear fault-code diagnostics (LA / SD / HT / PE / HH).
  • Compact and portable: generator Φ320×640 mm / 34 kg, controller 325×270×180 mm / <9 kg.
