Valves, Fittings, & Tubing for Hydrogen Applications

As the sole distributor of Maximator products in North America, MAXPRO® Technologies Inc. is an industry-leading provider of high-pressure solutions. We offer a range of components and systems manufactured for use in high-pressure applications and operations. 

Our high-pressure valves, fittings, and tubing are designed and constructed for durability and longevity. They offer excellent performance in demanding environments, such as those found in hydrogen applications. 

Hydrogen is extremely small and highly reactive. As such, it is essential to use the right types of valves, fittings, and tubing in hydrogen systems. Otherwise, there is a risk of explosion. Our line of hydrogen products is up to challenge!

Equipment Considerations for Hydrogen Applications

In hydrogen piping systems, any weak points may enable the pressurized gas to create small cracks or leaks that can lead to an explosion. That’s why it is essential to use properly designed and constructed pipes, valves, and fittings. Components for hydrogen applications feature high-pressure coned and threaded connections that are engineered to accommodate high pressures, high temperatures, and other extreme conditions without risk of leaking. 

In response to the growing popularity of hydrogen fuel cell systems, many standards, regulations, and codes have been established and adopted to address the safety concerns inherent to the technology. One such standard is ISO 19880, which specifies the safety performance requirements and proof of design test methods for components in gaseous hydrogen fueling stations. The third section of the standard outlines the requirements and restrictions for valves.

High-Pressure Valves for Hydrogen Applications

In pressurized systems, high-pressure valves provide protection against overpressurization and bursting. They are vital safety elements in hydrogen systems since they control the flow of gaseous hydrogen and enable the system to be shut down in the event of an emergency. However, they are also potential weak points at which hydrogen may be released unintentionally through leaks or cracks. 

High-pressure valves are built to handle extreme conditions in critical applications. Ones used in hydrogen piping systems are constructed from durable and reliable materials that are compatible with the process fluid, the process conditions, and the application environment. 

Many types of valves are used for hydrogen service, all of which have excellent closure capabilities. Those designed and manufactured for use in gaseous hydrogen stations include:  

  • Check valves
  • Excess flow valves
  • Flow control valves
  • Hose breakaway valves
  • Hose control valves
  • Manual valves
  • Pressure safety valves
  • Shut-off valves

High-Pressure Fittings and Tubing for Hydrogen Applications

The standard material recommendation for fittings and tubes used in hydrogen service applications is 316 stainless steel. The material is hydrogen compatible, meaning it will not degrade when exposed to hydrogen over an extended period. 

High-pressure tubing for hydrogen systems should have a seamless design to eliminate any potential weak points where cracks or leaks may occur. It should also be hard, not annealed, since hard tubing offers about 40% higher tensile strength than annealed tubing. 

Typical fittings used for hydrogen systems include:

  • Crosses
  • Elbows
  • Tees
  • Tubing end caps
  • Union and bulkhead couplings
