Oxygen Service Pre-Cleaning

Q. Are your products suitable for oxygen service pre-cleaning ?

A. Alconox detergent has been tested by the Compressed Gas Association (CGA) oxygen service testing.  Alconox® Powdered Precision Cleaner is typically used at a 1-2% concentration (5-10 g/L) in water to soak and flush through piping and oxygen service equipment followed by a thorough rinse that continues past the time when any foam is observed from the outlets of the piping system which confirms the removal of the Alconox.

Generally speaking all of our critical cleaning, free-rinsing aqueous detergents, followed by thorough rinsing, are appropriate for oxygen service. The detergent chemistry is often determined by the residue and substrate involved.  Often times in oxygen service, copper is present.  For soft, reactive metals (i.e. like copper) we want to go with an acidic detergent.  This would be Citranox® Liquid Acid Cleaner and Detergent.

You can access the relevant ASTM G93 and latest CGA publication.

Please contact us to discuss the most efficient detergent to use based on your substrate, cleaning mechanisms, and expected residues.
