Digital Wave Corporation is a privately held manufacturer of ultrasonic examination (UE) cylinder testing equipment, modal acoustic emission (MAE) testing equipment and a provider of associated inspection services. Modal acoustic emission testing, which is very different from standard AE testing, has become the premier nondestructive testing technique for inspecting composite pressure vessels. MAE is used to extend composite vessel life, requalify in situ vessels, monitor fatigue damage and to meet industry codes (ASME, NBIC, ISO, etc.). With applications worldwide, Digital Wave and its partners serve private and governmental clients in the compressed gas, pressure vessel and cylinder industries.
