RD-2805 Portable NDT Radiography Equipment — 280 kVp SF6 Gas Insulated X-Ray Generator, 45 mm Steel Penetration
Product Overview
The RD-2805 is a 280 kVp portable X-ray flaw detector built around an SF6 gas-insulated generator with anode-grounded heat sink and forced air cooling. The generator head weighs 26 kg and measures 280 × 610 mm, so a two-person crew can move it between weld joints, castings and pressure vessel sections without lifting equipment.
Maximum penetration is 45 mm of A3 steel with a 5 minute exposure, evaluated at 600 mm focal distance on Agfa film with double-sided lead foil intensification. Radiographic sensitivity is better than 2%, which keeps the system usable for code-governed weld inspection. The controller weighs 9 kg, runs fully automatic with a 4:1 work-to-rest cycle, and provides automatic control and protection circuitry.
Why This Model Fits Middle East Dealer Stock
- 220 V single-phase supply. Matches standard GCC and Levant site power, so no transformer is needed at the customer's yard.
- 45 mm steel penetration. Covers the pipe wall, valve body and structural weld range that dominates regional oil, gas and construction inspection work.
- Air cooling, no water circuit. Forced air cooling across an anode-grounded heat sink removes the water supply and chiller that water-cooled units require — a practical advantage in desert and remote yard conditions.
- SF6 sealed insulation. Stable high-voltage behaviour in high ambient temperature and dust, with a compact 26 kg head for scaffold and trench access.
- Wide ambient range. Rated for −30 °C to +40 °C, humidity up to 85% and altitudes to 1,500 m.
- Automatic operation. 4:1 work-to-rest cycle with a 15 minute maximum exposure per cycle, protection circuitry included, so operators need minimal training.
- Film or digital workflow. Delivered for conventional film radiography and compatible with DR panels when the customer later upgrades.
- Serviceable spare parts set. Gas filling valve, high-voltage cable, controller board and focal spot accessories available as dealer stock items.

FAQ
Q: Can the generator run on 220 V site power in the Gulf?
A: Yes. The unit is specified for single-phase 50 Hz, AC 220 V ± 10%, with an input capacity of at least 3.0 kVA. A stabiliser is recommended where site voltage fluctuates.
Q: What wall thickness can it cover in one exposure?
A: Up to 45 mm of A3 steel with a 5 minute exposure under the standard test conditions (600 mm focal distance, Agfa film, lead foil intensification, density ≥ 1.5). For thicker sections we supply higher-output generators in the RD range.
Q: Does it need a water supply?
A: No. The anode-grounded heat sink is cooled by forced air, which keeps installation simple on remote yards and in high-ambient sites.
Q: Is SF6 gas handling a problem for our service team?
A: The head is factory-filled and sealed at 0.45–0.5 MPa. We supply a filling kit and pressure gauge, and train your engineers on top-up procedure during commissioning.
Q: Can it be combined with a digital detector panel?
A: Yes. The generator can be paired with our DR flat panel detectors for film-free imaging; we quote the matched combination when you plan a digital upgrade.
Q: What support do dealers receive?
A: Operation and service manuals, spare parts list, remote diagnostic support, and on-site commissioning or engineer training arranged per order. Dealer terms for stock, demo units and territory planning are discussed per market.
