​Meyer Tool has specialized in custom cryogenic fabrication since 1969. Our experience spans a wide range of materials, processes and project sizes. Whether you need expert, precise fabrication of your prototype or batch production support for your custom ASME B31.3 cryogenic piping systems, Meyer Tool’s engineering and manufacturing team will support your needs. 

We apply a custom approach because every project has unique products and processes. Our team adheres to ASME B31.3 codes, which are the industry standard for the materials, design, components, fabrication, inspection and testing of process piping for many materials, including cryogenic fluids. Our Reduce Project Risk Process can help you save time, money and frustration over the life of your project.

Engineering for Safety, Compliance
​and Low-Temperature Demands

Our ASME B31.3 custom cryogenic piping systems are typically designed, either by Meyer Tool or our customers, for applications requiring the transfer of cryogens to meet specific system requirements and are not commercial off-the-shelf type designs. Process piping is purpose-built for industrial processing and manufacturing systems for cryogenic fluids. These include any fluid below minus 150° Celsius (minus 238° Fahrenheit), such as argon, helium, hydrogen, nitrogen, oxygen and methane. 

Cryogens and gases at cryogenic temperatures may also be transported. Typical systems are built from austenitic stainless-steel piping to ASME/ASTM specifications, though aluminum, stainless steel, carbon steel and high-performance alloys are also viable materials. The custom piping fabrication materials we use meet the standards' corrosion resistance, thermal and mechanical requirements. All internal piping is designed and fabricated to meet or exceed the requirements of ASME B31.3 Process Piping Code, including:
​
  • Pressure loads
  • Flow rates
  • Flexibility
  • Impact testing
  • Nonstandard loading situations

Our team will design components to withstand the internal pressure of the cryogens while factoring in:

  • Potential dynamic loads
  • Stress analysis
  • Corrosion
  • Thermal expansion
  • Temperature
  • Fluid characteristics

These expert design choices will keep the cryogenic fluid contained throughout the system, ensuring compliance with code safety standards.

Safety Testing for Compliance With ASME B31.3
​Process Piping Standards

Internal systems undergo the stringent inspection requirements of the ASME B31.3 code, including visual inspection of welds by our Certified Weld Inspector, radiography, nitrogen cold shocking, pressure testing and helium leak testing. Meyer Tool ensures your project complies with regulatory requirements while optimizing performance and controlling costs.
​
​Vacuum insulation is maintained by stainless-steel outer piping, welded by our ASME Section IX certified welders who build the inner piping. Final inspection requirements include helium leak testing with the inner line pressurized with helium gas and hydrostatic testing at 1.5 times the design pressure. We help ensure your project meets specs, avoiding rework while staying on your timeline.

Cryogenic Components We Use In ASME B31.3
​Piping Systems

Internal piping is super-insulated with spiral-wrapped multilayer insulation blankets made in-house by Meyer Tool technicians. Systems may include process valves, internal and external flex hoses and bends to accommodate temperature contractions. Additional design solutions include:

​While National Laboratories once primarily used this code, it has now expanded into commercial projects. Custom piping fabrication for cryogenic applications need to be specified to meet or exceed ASME B31.3 requirements. Our engineers will build a custom solution from the ground up to meet your unique specs.
