Oxygen cleaning services apply to oxygen as well as other industrial gases such as nitrogen and medical gas piping systems which follow similar cleaning procedures to that of oxygen.
Oxygen cleaning involves removing any combustible contaminates from all equipment surfaces intended to be used in oxygen service. Most common are instruments, tube fittings, pumps, valves, pipes and hoses.
Any process that handles >23.5% oxygen should be cleaned to remove contaminants such as hydrocarbon oils and greases, or anything that could ignite or spark, such as pieces of metal, dust and lint.
There are various specifications detailing the methodology that should be used, the permissible levels of contamination and the associated testing protocols used to certify the process.
Our O₂ cleaning procedure is based on ASTM G93-03 (Cleaning Methods and Cleanliness Levels for Material and Equipment Used in Oxygen-Enriched Environments). Other procedures such as mechanical or thermal may also be applied.
Oxygen cleaning options include:
- Vacuum packaging (small parts)
- 24hr turn around service
- Alternate detergents and surfactants
