Oxygen cleaning is the thorough removal of hydrocarbons (typically a grease or oil type substance) and other readily oxidizable materials from valves, fittings, pipes, and for use in medical oxygen service. NFPA 99C states materials for use in medical gas piping must be cleaned, plugged, capped and bagged until installed.
Ultrasonic energy is introduced into a cleaning solution causing cavitation. Ultrasonic energy causes alternating patterns of low and high pressure phases. During the low pressure phase, minute bubbles or vacuum cavities form. During the subsequent high pressure phase, the bubbles implode violently (this is called cavitation). Cavitation provides an intense scrubbing action that leads to unsurpassed cleaning speed and consistency. These bubbles are small enough to penetrate even microscopic crevices, cleaning them thoroughly and consistently. Resulting in one of the most highly effective and efficient methods of oxygen cleaning.
