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.
