Hexagon Digital Wave has pioneered two world-leading technologies for the non-destructive testing and requalifying of metallic and composite cylinders. Both of these inspection methods set the industry standard for speed, efficiency and cylinder life extension. Our Ultrasonic Examination (UE) technology is the most advanced method available for testing and recertifying metallic cylinders across a wide range of sizes. Its in use around the world by cylinder retesting facilities and companies that requalify large numbers of metallic cylinders (for industrial gasses, welding gasses, beverage or medical oxygen). Our Modal Acoustic Emission (MAE) technology is the worlds most precise and efficient method for testing and recertifying composite cylinders, which has made it extremely popular with fire departments, mining companies and natural gas transporters. Its truly a game-changer for recertifying and life-extending SCBAs, Type 1 tube trailers, and Type 3 and Type 4 fiber over-wrapped cylinders.
