What is the Standard for Cryogenic Pipeline?
Cryogenic pipeline systems are designed to transport extremely cold fluids-like liquid nitrogen, oxygen, hydrogen, or LNG-at temperatures often below -140°C. Because of the unique challenges at these temperatures, strict standards are in place to ensure safety, performance, and reliability.
Why Standards Matter
Cryogenic fluids can be volatile, and piping systems must withstand extreme cold without becoming brittle or leaking. Standards guide every aspect of system design-from material selection to insulation, welding, and testing-helping prevent failures and ensure long-term service life.
Key Standards to Know
ASME B31.3 – Process Piping
Widely used in industrial applications, it covers design, materials, fabrication, and testing. It requires impact-tested materials and flexibility analysis for low-temperature conditions.
EN 13480 – Metallic Piping
Common in Europe, it governs both normal and cryogenic-temperature systems with detailed safety and inspection requirements.
ASTM A333 & A358
Specify materials suitable for cryogenic service, especially low-temperature steels and stainless steel pipes.
ISO 21013 Series
Applies to vacuum-insulated piping, often used in laboratories, LNG, and medical gas systems.
