3 Tips to Keep High-Pressure Oxygen Systems Safe

Those with experience in the industrial gas industry know that high-pressure oxygen industrial gas operations have the potential to be very dangerous without the proper precautions and engineering. Oxygen is unsurprisingly a powerful oxidizing agent. This means that oxygen has the ability to accept electrons from other substances and start the redox chemical reaction of combustion. Every high-pressure oxygen piping system has the ever-present risk of combustion and fire under the wrong conditions. Even typically ordinary objects can start combustion around leaking oxygen. Despite these inherent risks, many industrial gas operations and a variety of other industries continue to safely utilize high-pressure oxygen in vital applications. When it comes to keeping a high-pressure oxygen system safe, proper knowledge and quality engineering are key. At CPV Manufacturing, we have in-depth experience with vital parts of oxygen piping systems. Here are some tips about how the experts keep high-pressure oxygen systems safe.

1. Use Valves Designed for High-Pressure Oxygen

Valves are one of the parts of a pipeline most prone to issues. A major danger to high-pressure oxygen pipelines is adiabatic compression. A rapid change in pressure caused by a valve that opens too suddenly can cause compression and generate heat. Equipment like CPV’s oxygen master valves are designed to prevent this from happening. Never use ball, butterfly, or globe valves in oxygen systems. Valves like our oxygen master valves and other needle valves can prevent ignition from adiabatic compression.

2. Prevent Leaks

This is an obvious but vital part of keeping a high-pressure oxygen system safe. Tiny leaks can expose oxygen to many ignition sources outside of a pipeline. Valves are again one of the most common culprits for this issue. Quality oxygen master valves and needle valves that are designed for high-pressure systems can help prevent leaks in a pressurized system. Also, frequent inspections and maintenance can help protect your valves and pipe systems from wearing down and leaking.

3. Eliminate Sources of Ignition

This tip is not as straightforward as it may seem. Oxygen only requires sufficient energy as an ignition source. Ignition sources include, mechanical impact, particle impact, friction, and many heat sources. Make sure to wear gloves and thoroughly clean when you inspect and maintain your oxygen pipeline, to prevent any particles from entering. Remove objects that could cause mechanical impacts around the pipeline. Be sure there is no wear or lose materials that could cause heat via friction. Providing proper cleaning and maintenance is vital for keeping your high-pressure oxygen system free of ignition sources.

The Preferred Choice for Oxygen Service

If naval brass sounds like something that’s meant to be used in the ocean, it’s because that’s exactly what it was designed for. Naval brass is a copper alloy containing zinc – about one percent tin and just a hint of lead in addition to the copper. Fortunately, its use is not restricted to just the sea.

Though copper by itself is useful for many applications, the addition of zinc boosts its strength. Brass with more than 39 percent zinc (like naval brass) has higher strength but lower ductility than that with less zinc.

The addition of a little tin increases brass’s corrosion and dezincification (the leaching of zinc) resistance. And though it is a minute amount, the lead boosts the material’s machinability.

Naval brass falls under the alpha-beta brass (or duplex brass) classification and is harder and stronger than other classes of brass.

Oxygen Valves

You may wonder then if naval brass was designed for marine use, why on Earth do we use it for oxygen service?

To answer this question, we need to talk about oxygen for a minute.

Oxygen is an oxidizing agent. An oxidizer itself is not combustible. But combine it with a flammable substance and a source of ignition, and you have a major fire hazard. That ignition source does not have to be a spark or flame. At the right pressure, heat has the potential to ignite combustible materials.

On top of that, when moisture is added to oxygen in the presence of iron (or iron-containing materials), a chemical reaction occurs. The oxygen and moisture corrode the iron, forming iron oxide (more commonly known as rust). Rust does more than just look bad. Rust corrosion, like any other form of corrosion, weakens the metal.

So when outfitting an oxygen-rich system with valves, it is important to address both of these properties of oxygen in the valve material selection.

  1. Materials that are susceptible to oxidation or corrosion need to be avoided.
  2. The materials used should be those least likely to catch fire.

Low Fire Risk

Most valve materials will not ignite at gaseous oxygen’s normal temperature. Where the risk comes in is with the chance of localized hot spots. High localized temperatures can result from sources such as vibration, foreign particles or debris, adiabatic compression, or static electricity.

Even a high flow velocity can result in heat from friction. In fact, if there is a chance that the velocity through the valve will pass 200 feet per second, the Compressed Gas Association (Pamphlet G-4.4) allows only copper alloys to be used as the valve body and any parts that contact gaseous oxygen.

Of all the metal options, copper alloys are the most effective for resisting ignition and have the slowest combustion rate. For that reason, naval brass ranks at the top of the list for fire and explosion safety purposes.

Corrosion Resistant

Corrosion and leakage are not wanted in any system. In an application such as oxygen service, corroded and leaking valves are dangerous. For safety and fiscal reasons, oxygen valves must be corrosion resistant and leak-free.

Again naval brass‘s corrosion resistance means it is a preferred choice for use in oxygen service.


It’s crucial that the right products be chosen for oxygen applications and that all are handled with care. That includes proper cleanliness. (Read about our class 10,000 cleanroom here.) We will work with you to ensure that you get the valves and fittings that fit your company’s needs.

What is Oxygen Cleaning?

Oxygen Cleaning for Quality and Safety

If you’re not familiar with the terminology, it’s not what it sounds like. Oxygen cleaning is a method of cleaning equipment intended for use with either liquid or gaseous oxygen.

Contaminants in an oxygen-rich system pose serious risks. Where used in industrial settings, oxygen cleaning eliminates fire or explosion danger due to flammable contaminants. When being used for medical purposes, oxygen cleaning removes contaminants that can cause direct bodily harm.

Oxygen and Fire

An oxidizer such as oxygen is one of the three things needed for fire. The other two are a fuel (something to burn) and a source of heat or ignition. When an uninhibited chain reaction is added to an environment with a strong oxidizer, the result can be explosive.

Oxygen is used in many industries from chemical processing to pharmaceutical and healthcare. Because of its highly reactive nature, all systems where oxygen is present must be free of any contaminant(s) that could serve as a fuel for combustion.

Many CPV customers including but not limited to pharmaceutical, aerospace, chlorine, and the compressed gas markets, use industrial oxygen or other oxidizers such as chlorine in their operations on a daily basis.

In such an environment, the potential heat source can come from things such as:

  • Friction from materials (such as metals) sliding against others
  • Electricity in the form of static electricity or electrical arcs from equipment
  • Impact or being struck with an object or particle
  • Vibration or resonance
  • Compression of a liquid, known as Heat of Compression


When a fuel source (which could be a contaminant or the metal itself) in an oxidizing environment spontaneously ignites because of heat produced by sudden compression of a gas or liquid (Heat of Compression), autoignition occurs. If compression such as that created in a valve when it opens and closes generates enough heat…that’s heat in excess of the known autoignition temperature…spontaneous ignition results. In such an oxygen-rich environment, that probably means explosion.

In order to control Heat of Compression and limit temperatures to within the autoignition range in oxygen-rich systems, pressure drops are limited.

Contaminants come into play because they can have even lower autoignition temperatures than the valve components, which means that explosion could occur at lower temperatures…temperatures less than the autoignition temperature of the valve components.

That’s why it’s so crucial that any and all potential sources of fuel be removed from an oxidizer-rich system or environment.

Types of Contaminants

What exactly needs to be removed during cleaning? A contaminant is essentially anything that would cause combustion or autoignition or affect the purity of the product. According to ASTM G93, there are three types of contaminants:

  • Organics
    • VOC compounds
    • Hydrocarbon-based greases and oils
  • Inorganics
    • Nitrates
    • Phosphates
    • Water-based detergents & cutting oils
    • Acids/solvents
  • Particulate
    • Particles, lint, and fibers
    • Dust
    • Welding slag

Cleaning Mechanisms

The cleaning can be carried out in a number of ways. The method depends primarily on the nature of the contaminant and the requirements set forth by standards or any additional customer specifications. The following is a partial list of cleaning methods:

Mechanical cleaning

  • Includes sandblasting, grinding, and wire brushing
  • Removes scale, paint or coatings, and welding slag

Aqueous cleaning

  • Hot water and steam – with or without detergent
    • Removes water-soluble contaminants
    • Spray or agitation
    • Detergent must be rinsed off before drying
  • Alkaline or caustic cleaning
    • Caustic salt is dissolved in water creating a solution with high alkalinity
    • Removes hydrocarbon oils, grease, and wax
    • Can be sprayed, immersed, hand swabbed, or enhanced by agitation or ultrasonic agitation
    • Solvent residue must be removed before drying

Semi-aqueous cleaning

  • Hydrocarbon solvent and water emulsion
    • Removes heavy grease wax and hard-to-remove soils
    • Agitation needed to mix and maintain the mixture
    • Emulsion must be rinsed off

Acid cleaning

  • Hydrochloric acid
    • Removes scale, rust, and oxides
    • Will strip chrome, zinc, cadmium and other platings or coatings
    • Recommended only for carbon and low alloy steels
    • Must be removed/rinsed
    • May require neutralization
  • Chromic acid or nitric acid
    • Used for deoxidizing, brightening, and removing alkaline residues (black smut)
    • Removes/cuts oils
    • Recommended for aluminum, copper, and their alloys
    • Must be removed/rinsed
    • May require neutralization
  • Phosphoric acid
    • Removes oxides, light rust, and fluxes
    • Must be removed/rinsed
    • May require neutralization

Solvent washing

  • Alcohol or other solvents
  • Used to re-clean areas as warranted by inspection
  • With or without water dilution or emulsion
  • No residue/does not need to be rinsed

Vapor degreasing

  • Effective on inaccessible areas
  • Uses a vaporized solvent while the part to be cleaned is kept at a lower temperature

Inspection Techniques

After cleaning and before being assembled and packaged, valve components go through an inspection to ensure they meet minimum cleanliness requirements. Inspection can be done in any of the following ways:

Visual inspection

White light is used to detect contamination by visible particles, while ultraviolet light (black light) is used to detect particles that fluoresce.

Wipe test inspection

A wipe test is where a clean white paper or lint-free cloth is used to lightly rub the surface of areas that cannot be seen. The cloth is then inspected with both white and UV light.

Water break test inspection

The surface is sprayed with clean water. If the surface is free of oily residue, it will form a thin layer that remains unbroken for at least five seconds. The water will bead up into droplets if there is any oil remaining on the surface.

Solvent filter inspection

For solvent filtering, the inaccessible area is rinsed with a solvent which is then filtered to capture any remaining contaminants. The filter is inspected with white and UV light.

Quantitative inspection

Quantitative inspection involves evaporation of the cleaning solvent to determine the weight of the remaining particles, which will be the contaminants.

It’s up to the user or customer to determine what level of residue is acceptable.


At CPV Manufacturing, our quality control standards are high. That’s why we have our own oxygen cleanroom.

Employees are specially trained to operate the cleaning and inspection equipment in the cleanroom. Our cleanroom is Class 10,000, meaning the particulates must be less than 110,000-micrometer particles per cubic foot.

Having our own in-house cleanroom facility allows us to ensure that industry standards, as well as our quality standards, are met or exceeded.



Once the parts have been cleaned, and it’s been verified that all contaminants have been removed, they can be assembled. The finished valves are then packaged in a way to keep them clean until they’re ready to be put into use.

In the end, it doesn’t matter how it’s done, as long as the required level of cleanliness is achieved and our customers are satisfied.

Oxygen cleaning is just one more way we ensure that our high-quality products meet or exceed all relevant standards. Contact CPV Manufacturing for more information about what we can do for you.

Preventing Oxygen Valves Fires: Kindling Chains and Common Ignition Mechanisms

When working in the compressed gas field, it’s important to be aware of the dangers that could arise from ignitions. Even more important is understanding what to do to prevent these ignitions for the safety of the facility and the facility workers.

The European Industrial Gases Association (EIGA) discusses oxygen pipeline and piping systems used in the industry and how to ensure their safe design and operation. Being well-versed in the safe design, manufacture, installation, operation, and maintenance of valves used in liquid oxygen and cold gaseous oxygen systems is crucial to prevent damaging incidents.

oil-workersTo make sure that liquid oxygen valve specifiers, suppliers, and manufacturers and those who clean, assemble, install, operate, and maintain these valves understand how to reduce the risk of ignition, the EIGA released a publication that covers isolation valves, check valves, pressure relief valves, and drain and vent valves in air separation units and their backup and storage piping systems. Learn more about the details of the publication below.

Common Ignition Mechanisms

Typically, the most common ignition mechanisms occur because of improper system or component cleaning, improper operation, or improper maintenance. Your system’s oxygen concentration, pressure, gas velocity, and temperature are also factors. These factors can influence ignition mechanisms, which can result in combustion.

About Kindling Chains

EnergyGenerator_ManWhen there’s a kindling chain, either a contamination in the system or a non-metallic component ignites. The combustion continues to ignite materials, thus producing a chain.

To minimize the risk of a kindling chain, the system must be cleaned and meet oxygen requirements. Other methods include eliminating ignition mechanisms where possible; increasing the burn resistance of valve components; reducing dirt, debris, particles, hydrocarbons, and cleaning agent residues in a valve; eliminating metallic particles that form during assembly; and avoiding environmental contamination.

Reduce Probability of Ignition

The changes that this publication recommends to reduce the probability of an ignition or mitigate the risk of a kindling chain include several steps.

  • Eliminate or minimize the mass of non-metal components.
  • Use non-metals with a higher auto ignitions temperature, higher mechanical resistance, and lower heat of combustion.
  • Use burn-resistant alloys suitable for the operating conditions.
  • Design so metal components are at a thickness that’s burn-resistant suitable for the operating conditions.
  • Design to protect non-metals by avoiding contact with direct flow and encapsulation in metal as much as possible.
  • Change operating parameters for transient/worst-case scenarios.
  • Mitigate consequences through isolation/barriers.

Because safety is the top priority at CPV Manufacturing, we make sure that the parts we supply that are used in oxygen service are cleaned. One way we ensure safety is with our 10,000 class oxygen clean room.
