Oxygen Cleaning

Astro Pak has a wealth of experience and success in providing Oxygen Cleaning service for O2 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 provides 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, we will clean liquid and gaseous oxygen components at your project location.

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.


Trust the Experts

For nearly 60 years, Astro Pak has been perfecting the chemistry and cleaning process of Passivation. Our proprietary chemistry, UltraPass® is a chemical treatment for stainless steel and other metals that enhances the ability of the treated surfaces to resist corrosion.

Astro Pak delivers chemical cleaning & passivation services to installed systems: pre-operational, pre-commissioning of new construction, post modification, or for maintenance during shut-downs. Whether it is UltraPass®, nitric acid, or other chemistries, we process piping, fittings, vessels and other types of equipment. Astro Pak also performs Gel Passivation to address surface discoloration, spot rouge, HAZ of welds, or corrosion on exterior surfaces. We perform oxygen cleaning at customer facilities or project sites or in one of our nationwide locations

We routinely respond to emergency situations for critical utilities, systems and equipment. When our job is complete, you will receive cGMP compliant documentation packages for your systems and equipment maintenance records.
