OXYGEN CLEANING

Oxygen (O2) cleaning is a vital service developed for the removal of flammable contaminants that can potentially facilitate ignition in an oxygen-rich environment.

While oxygen itself is not flammable, it acts as a powerful oxidizer for fuel. By removing contaminants—such as oils, greases, or even dust—from the components, piping, and equipment that support oxygen utilization, the risk for catastrophic fire or explosion can be greatly mitigated.

ASTM G93 is the Standard Practice for oxygen cleaning, but individual applications often vary.  Additionally, some owner-operators have developed their own specifications that expand on this standard.

ASTM G93 is the Standard Practice, set forth by the American Society for Testing & Materials (ASTM), for Cleanliness Levels and Cleaning Methods for Materials and Equipment Used in Oxygen-Enriched Environments.

These cleaning procedures, commonly referred to as Oxygen Cleaning or O2 Cleaning, follow specific processes for the cleaning of equipment, pipework, and peripherals used in the storage, transport. and utilization of oxygen.

MIG's highly trained and certified personnel perform outstanding O2 cleaning of piping, tubing, hoses, valves, and components, supporting oxygen service.
