350kVp Portable X Ray Flaw Detector RD-3505 55mm Steel Penetration for Industrial NDT Inspection
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.
