Oxygen Cleaning

Astro Pak has a wealth of experience and success in providing oxygen clean service for oxygen enriched systems and surfaces. We deliver chemical cleaning services to installed systems: pre-operational, pre-commissioning of new construction, post modification, or for maintenance and shut-downs; as well as the capability to process large parts and equipment at one of our nationwide Shop locations.

Oxygen enriched environments require not only combustible organic contamination removal, but also an optimal passive surface, which will provide corrosion resistance. A passive layer surface will inhibit oxidation, thus minimizing particulate contamination. Technical cleanliness verification with analytical methods is a vital part of our superior quality effort. In addition to our onsite cleaning of your oxygen systems, Astro Pak will clean liquid and gaseous oxygen components in our CA or VA cleanrooms or at your project location with environmentally safe alkaline cleaning chemistries.

Pre-installation cleaning of components or piping sections may be processed at our facilities or onsite with permitted organic solvents or alkaline chelant cleaning systems. Astro Pak only uses approved chemistries and cleaning processes to provide certification to meet multiple ozone and oxygen piping system specifications, as well as for aerospace launch facility gas system cleaning and verification. Oxygen cleanliness specifications are also used in a variety of other liquid and gaseous environments, including nitrogen & hydrogen storage and distribution systems.

Astro Pak’s fleet of vehicles, mobile skids, equipment and chemicals allow us to come onsite to meet your oxygen cleaning requirements. Immediate response for emergency outages and critical utilities are routinely provided.

If your requirement is to have precision cleaning and packaging for Oxygen Service of components, tubing and other items to be cleaned for oxygen service prior to installation, Astro Pak can also meet those needs at our modern state-of-the-art Class 5 (Class 100) and Class 6 (Class 1000) cleanrooms.
