A guide to critical cleaning of oxygen components and services
Guide to critical cleaning of oxygen components
The COVID pandemic of 2020-2023 increased the demand for critical cleaning of oxygen components to treat patients with symptoms. The need for respirators and installation of new and extended oxygen systems in hospitals, clinics and care homes with the provision of ancillary pressure reduction and delivery systems led to a massive increase in demand for the valves, fittings and pipelines which control the supplies from storage tanks and cylinders, all of which needed critical cleaning.
CLEANING OXYGEN COMPONENTS
Critical cleaning of oxygen components is a crucial process to ensure the safety and reliability of systems that handle oxygen, especially in industries like aerospace, healthcare, and industrial gas production.
Cleaning for oxygen service is best defined as the removal of combustible contaminants from the surface of any equipment or system in oxygen service. Essentially, any component that may encounter an oxygen rich environment. The combustible contaminants include organic and inorganic substances such as hydrocarbon material for example oils and greases, paper, fibre, dust, and soils. If these contaminants are not removed properly, in a worst-case scenario, this can cause combustion or explosion in an oxygen atmosphere or at the least rejection of the product due to unacceptable product purity.
Oxygen is not flammable, but it supports combustion. Oxygen can react with most materials. The higher the oxygen content and/or pressure in a system the more vigorous the combustion and the lower the ignition temperature required. Materials that do not normally ignite in air will burn and may explode in an oxygen rich environment. In addition, the oxygen rich environment will give rise to a higher flame temperatures and combustion velocity with potentially devastating consequences. The recognition of oxygen’s reactivity has led to stringent requirements regarding the cleanliness of equipment in oxygen service. Strict guidelines exist to ensure that care must be taken in the selection of equipment including all materials and components, which all need to be oxygen compatible. They must also be free from combustible contaminants as described above.
Consideration must be given to any cleaning processes employed in the manufacture and maintenance of all components of oxygen service systems. There are many options depending on the type of contaminants from aqueous to semi aqueous and blasting systems, to removal of welding slag etc. These are all referenced in the section below.
INDUSTRY STANDARDS FOR OXYGEN SERVICE CLEANING
As part of the programme of worldwide harmonisation of industry standards, the ‘European Industrial Gases Association’, (EIGA) published Cleaning of equipment for Oxygen Service Doc 33/18. The publication was developed from the Compressed Gas Association Document G-4.1 Cleaning Equipment for Oxygen Service by the ‘Compressed Gas Association’.
Specific consideration must be given to the following:
- Cleaning standard to be achieved (how clean is clean?).
- Cleaning procedure.
- Solvent cleaner to be used.
- Surface properties of the parts to be cleaned.
- Shape and geometry of the material.
- Types and amounts of contaminants.
- The degree of automation required.
The size and capacity of the equipment is determined by:
- The size of the material or components to be cleaned.
- The required throughput.
Your starting point should be the cleaning standard and procedure. Solvent cleaning and solvent vapour phase cleaning of components consists of the removal of contaminants by immersion in the solvent, possibly with the addition of ultrasonic agitation and the action of continued condensation of solvent vapour on the component surfaces. The procedure requires that the oxygen equipment, system or component is colder than the solvent boiling point. This allows the vapour to condense on the components and perform a final rinse.
The major significant advantage of solvent cleaning is that vaporised solvent is always pure, and the contaminants remain in the boiling liquid section which requires only periodic cleaning out, thus causing a reduction in the frequency of system downtime. The effectiveness of a particular cleaning agent depends upon the method used, the nature and type of the contaminants and the characteristics of the article being cleaned, such as size, shape, and material. Final evaluation of the cleaning agent should include testing of actual products and production processes. All equipment must, together with the cleaning chemistry, comply as a minimum with current legislation for health, safety and environment. The efficiency is controlled by utilising typical samples, written procedures and requested criteria for cleanliness.

SuperCORR A -Advanced corrosion protection for aircraft
Advanced corrosion protection for aircraft – SuperCORR A lubricates and protects mechanical and electrical flight controls in surveillance aircraft.
Super CORR A provides advanced corrosion protection for aircraft – It lubricates and protects mechanical and electrical flight controls and electronic equipment in Lockheed Martin P-3C Orion aircraft flown by air forces around the world for anti-submarine and maritime surveillance, also used in searches for missing ships or aircraft.
The Royal Australian, Korean and Japanese Air Forces were employed in the search for the Malaysia Airlines flight MH370 Boeing 777 passenger jet which disappeared on a scheduled flight in March 2014. The search for debris in a vast area of ocean, bigger than the land area of Europe, southwest of Perth, Australia operated for thousands of hours at low levels but failed to locate any debris and was suspended in 2017.
The maintenance schedules specify Super CORR A to lubricate and protect the flap tracks and screw jacks in the wings of the aircraft which are constantly exposed to extremely corrosive salt laden air as the aircraft in search mode can be flown at very low altitudes of hundreds of feet for long periods.
Super CORR A lubricant and protective coating is widely used by the military, electrical, electronics and aerospace industries for critical applications to give the protection needed in extreme conditions. Super CORR A deposits a dry protective film with excellent corrosion protection and lubricant properties plus the added advantage of a hydrophobic surface rejecting water that ensures the easiest and best connections for very close spaced connectors, contacts, wiring and moving parts
The U.S. Navy selected Super CORR A after exhaustive testing using American Society for Testing and Materials (ASTM) Standard B117- Standard Practice for Operating Salt Spray Apparatus.
Super CORR A, a Type I, Grade B Corrosion Preventative lubricant out-performed 11 other products in comparative testing to identify the best product to protect and lubricate the flap tracks and screw jacks on the aircraft.
The flap tracks, located in the aircraft’s wings, are what the flaps slide on when they move up or down to lower or increase speed. The screw jacks engage and retract the wing flaps. Corrosion on any of the surfaces can lead to snatching or vibration which can affect the pilot’s control
Due to constant operation in salty and corrosive atmospheres which need post-flight rinses and monthly washing down of the aircraft re-lubrication and corrosion treatment for the flap tracks and screw jacks is required each time, with conventional lubricants, to prevent rusting. Super CORR A was evaluated against competitive products under the Federal Test Method Standard #791B, using a five percent Salt Spray Corrosion Test.
Super CORR A far exceeded the performance of the other products evaluated. After over 200 hours of continuous exposure to salt spray corrosion, Super CORR A protection actually increased over time where all the other, similar, products failed early or contributed to an increase in corrosion.
The accelerated salt fog corrosion testing demonstrated that the application of
Super CORR A which complies with MIL-DTL-87177B (revised MIL-L-87177A) also increased electrical operation to 1400 hours versus 100 hours for the control product used at that time. Technical manuals were updated to include the application for electrical and mechanical parts for civilian and military operations.
The most important conclusion from the historical data and prototype testing is the availability of this excellent corrosion preventive compound that has dry film lubricant properties. The application of Super CORR A on aircraft components can reduce maintenance man hours, reduce part replacement costs, increase life of aircraft, safety, and readiness for operations.
Estimates for the maintenance cost for the US Air Force F-16 fleet can reach $500 million per year, the use at all military branches could reach billions of dollars per year. Applications at locations tested by the U.S. Air Force are not normally treated with corrosion prevention and control lubricants (CPC’s). These are the electrical connectors that are susceptible to subtle and not so subtle forms of corrosion that can interfere with the electrical operation of the F-16.
Testing by the U.S. Navy at NADEP Jacksonville incorporates not only electrical connectors, but mechanical and structural components as well. Future uses will also include ground support equipment. The properties of Super CORR A are such that it can be used in a wide variety of applications and on any materials, metal or plastic. Properties of the Super CORR A far exceed the requirements defined by the MIL-L-87177A specification. Many of the beneficial properties of the product are not required in the MIL specification.
EnviroTech Europe is a manufacturer and distributor of anti-corrosion, lubricants and coatings used on wiring, connectors, switches, circuitry, avionics. Read the full report – ‘Use of MIL-L-87177A as a corrosion prevention compound’ in our Library https://www.corrosion-protect.com/resources

Aquus CL-One Concentrated all-purpose cleaner
Aquus® CL-One concentrated all-purpose cleaner – Water based cleaning and protection of metal surfaces prior to powder coating or painting.
Aquus CL-One is an excellent all-purpose cleaning system for the cleaning and protection of mild steel and ferrous metal parts which need powder coating or painting immediately or when it is necessary to store unpainted for limited periods. Any cleaning system can be used – hand wiping, dip tanks, ultrasonics or pressure washing.
Uncleaned metal components or fabrications before cleaning are protected by process oils and grease on the metal guarding the surfaces from changes in humidity. Once removed using conventional water-based cleaners flash rusting can occur very quickly during drying.
The unique Aquus CL-One formulation however leaves an invisible barrier on the metal surfaces, after the cleaning process, providing extended corrosion protection during storage, fabrication, or assembly before finishing. The barrier film can be powder coated or painted over without additional rinsing and without affecting adhesion of the coatings.
General purpose cleaning
Aquus CL-One is also an excellent general-purpose concentrated surfactant system containing no solvents which exhibits a unique combination of characteristics that are not found in other commercially available cleaning processes biodegradable, non-flammable, non-toxic at used concentrations and, unlike almost all other surfactant systems, is both hydrophilic (water attracting) and oleophobic (oil-repelling).
Aquus CL-One offers exceptional emulsion-breaking capability in addition to its unusual combination of properties that makes it so attractive for a wide range of industrial applications. In addition to the general cleaner Aquus CL-One, other concentrated cleaners within the range are formulated to offer cleaning solutions for industry specific applications.
One cleaner for all applications
One cleaner for all applications reduces costs by removing the need for multiple cleaning products usually needed to deal with a wide range of soils or contaminants. Safe for the environment and users, containing no solvents is biodegradable within 30 days. Typical with only one product for all cleaning applications incorrect selection or dangerous uses can be avoided.

Corrosion protection for unpainted metal in highly corrosive environments
Tests demonstrate the amazing properties of SuperCORR A corrosion protection spray to protect unpainted metal surfaces from corrosion
These are photographs of 3 unpainted copper components that were exposed for a month next to the “digester” at a Pulp and Paper Mill. The part marked #1 was the control and not sprayed with SuperCORR A corrosion protection spray. Half of part marked #2 was sprayed with SuperCORR A and half left uncoated. Component #3 was completely treated with SuperCORR A. The main atmospheric corrosion was from hydrogen sulphide (H2S) gas, produced during the cellulose digestion process, which combines with the atmospheric humidity to form a mild acid. Any unpainted or untreated metal surface, copper, brass, mild steel or alloys of zinc and manganese or magnesium will be corroded by this acid when it condenses on the metal surfaces.
This is especially important in electrical motors and power control systems where these metals are used as conductors or switch contacts on printed circuit tracks and all types of connectors which although sealed in control panels will be exposed whenever the boxes are opened or contactors operated and connectors plugged and unplugged. In most cases it is not possible to paint these conductive surfaces or apply other forms of protection without loss of conductivity leading to arcing or supply failures.
These tests demonstrate the amazing properties of SuperCORR A to protect unpainted surfaces from acidic corrosion. As an example, copper and aluminium condensers on water coolers usually last about a month in the acidic environment of pulp production facilities because the corrosive atmosphere around the plant corrodes the metal surfaces on fins and connections.
A trial was set up by the works engineering department at the plant who sprayed a new condenser with an aerosol of SuperCORR A corrosion protection spray. This applies a very thin protective film of a proprietary formulation containing extremely long-lasting anticorrosion inhibitors, which also give superior lubrication coefficients and protect components against moisture. This unique, water displacing lubricant, with synthetic corrosion prevention compounds is tested and proven non-flammable and environmentally friendly without sulphates, chlorides, or other halogens
After a few months the treated condenser showed so little signs of corrosion that further controlled trials were set up to test for long term protection of untreated metal in this extremely corrosive environment experienced in paper and pulp mills, water processing plants and oil drilling rigs.
The improvement is clear and demonstrates the savings in costs of parts and labour for maintenance and replacement untreated metal components exposed to these corrosive conditions.

Cleaning solvent for vapour degreasing in the aerospace industries
ProSolv® 5408 sustainable, economical cleaning solvent for vapour degreasing in the aerospace industries
The aircraft and aerospace component manufacturing industries face many critical cleaning applications during manufacturing processes and for finishing where surfaces need to be completely degreased leaving no residues. Although aqueous cleaning would seem to be the method of choice for environmental reasons with new advancements in cleaning solvent chemistry this is often not the case. Vapour degreasing is the most effective process, economical in use with lower energy uses, one tank needing less floor space than multi tank water-based systems and safe for users.
ProSolv 5408e has been developed to be used in place of the traditional chlorinated hydrocarbon solvents, trichloroethylene and perchloroethylene and those based on n-propyl bromide (nPb) which have been phased out for use as vapour degreasing solvents in the EU. The ProSolv 5408e advanced formulation, based on sustainable solvents, has been extensively tested with oils, soils greases and other contaminants from the manufacturing process and with is high KB value all these materials are easily removed to comply with aircraft standards for cleaning and degreasing to the highest levels. No titanium surface cracking or deleterious effects on other metals or composites commonly used for aircraft and aerospace component manufacture have been identified.
The innovative ProSolv 5408e formulation produced by Envirotech Europe ticks all the boxes with the perfect profile for vapour degreasing Soft on the environment with near zero ozone depletion potential (ODP) and very low global warming potential (GWP) its lower boiling point at 48C minimises energy requirements giving reduced process times for greater throughput and comfortably handled critically cleaned parts. The incredibly low surface tension guarantees penetration into micron sized through and blind holes and between close contact surfaces.
Stable in use ProSolv 5408eis safe for users with a high 8hr occupational exposure level of 220ppm. The solvent needs no additives or stabilisers and requires no testing. Sustainable, safe and secure for future use as your forever solvent.
CRITICAL CLEANING FOR THE AIRCRAFT INDUSTRY
A few examples of the many uses are discussed below, our technical service engineers can offer information and advice on critical cleaning in the multitude of other applications experienced in the precision engineering industries.
BONDING OF HONEYCOMB SECTIONS FOR COMPOSITES
An instance of critical cleaning is removal of all contamination from aluminium honeycomb prior to epoxy resin bonding of the formed aluminium skin to produce lightweight high tensile structures for applications such as leading edges on aircraft wings and wind turbine blades. This is an extremely demanding application, as any residues will prevent the adhesion of the adhesives leading to delamination with potentially disastrous effects.
Due to the high standards of cleaning which are required this process is usually carried out by vapour/liquid degreasing with the traditional chlorinated solvents however due to the increasingly stringent controls on these materials ProSolv 5408e which is fully tested to aircraft industry standards and with its greatly improved environmental and user profile is now increasingly used as the sustainable and safer replacement.
CLEANING FOR CRACK AND FAULT TESTING OF WELDS AND CASTINGS
Another common use in the aircraft industry is in the cleaning of castings and metal fabrications before the use of NDT crack detection fluids. Removal of all surface contamination from manufacturing processes is vital to expose faults. Vapour degreasing and vapour liquid cleaning with ultrasonics is a favoured method due to the excellent solubility of oils and greases and other soils using one tank with very fast processing and parts emerging completely clean and dry. Crack and fault detection in casting and welds is also important in other industries such as railways, automotive engines, and turbines where castings or critical welded fabrications are used. This is particularly relevant as part of the maintenance procedure for refurbishment of aircraft landing gear where surfaces can be heavily contaminated by hard to remove hydraulic oils, rubber and cement dust and grease.
Because this application needs completely degreased, residue free and dry surfaces, the use of slow drying cleaners such as hydrocarbons or water-based cleaners may cause problems as the cracks need to be dry to allow penetration of the detection fluids. Vapour degreasing is the most effective cleaning system for all NDT applications as parts emerge dry from the cleaning process. ProSolv 5408e conforms to SaE-AMS2664 and E1417 99-1/7-1-1 solvent precleaning standard for Penetrant testing in aerospace applications.
CRITICAL CLEANING OF OXYGEN AND GAS SYSTEMS
Critical cleaning of oxygen lines and tanks where no organic residues can be tolerated is another ideal use for this new sustainable cleaning solution. ProSolv 5408e conforms to CGA, ELIGA and Compressed Gas Association standards for this application. We have a series of guides to using ProSolv 5408e for component cleaning to Oxygen standards and recommended cleaning methods involved, available on request.
ProSolv 5408e is produced to consistent quality standards worldwide and is available through a network of experienced and qualified suppliers.
