Global leader in cylinder testing and monitoring technology

We have set a new safety standard for cylinder testing and requalification of high-pressure cylinders. Our solutions reduce cylinder and system downtime and inspection costs while improving inspection accuracy and safety.

Ultrasonic Examination (UE) Testing

Hexagon Digital Wave is a pioneer in Ultrasonic Examination technology. Our UE machines are in use worldwide by both in-house and independent testing facilities for testing and recertifying metallic cylinders containing industrial gasses, welding gasses, beverage or medical oxygen.

UE technology quickly identifies even the most minute structural flaws in metallic cylinders using ultrasound waves and advanced scanning technology. This provides a far more efficient and thorough inspection than traditional hydrostatic testing.

Modal Acoustic Emission (MAE) Testing

We perform Modal Acoustic Emission (MAE) testing to inspect, monitor and requalify composite cylinders, mobile pipeline modules, Type 3 trailers and other composite vessels. MAE is performed by placing transducers on the surface of a structure that’s being tested, applying stress and recording the ultrasonic stress waves. MAE technology has proved extremely valuable for testing and requalifying:

Large composite cylinders used in the transport of natural gas
Self-contained breathing apparatuses (SCBAs) used by fire departments

Our advanced MAE technology helps transporters of natural gas (and other gasses) save time, money and hassle by testing and requalifying the large composite gas cylinders directly on trailers. Since our convenient test method can typically be completed in a single day, it keeps the so-called mobile pipeline or virtual pipeline moving along. By contrast, other test methods can put trucks out of service for weeks or months while cylinders are being disassembled, tested and then reassembled.

Our MAE testing is a game-changer for fire departments. In the past, firefighter air tanks could be used for a maximum of 15 years. Hexagon Digital Wave is the only testing service approved to extend the life of SCBAs to 30 years! This saves fire crews a great deal of money on replacement canisters and prevents many tons of cylinders from being added to landfills each year.
