T/CMEPCA 101-2025 Guidelines for design and manufacture of cryogenic valves for hydrogen
Basic Information
Scope
This document specifies the classification and models, technical requirements, test methods, inspection rules, marking, packaging, transportation, and storage of low-temperature valves for hydrogen. This document applies to gate valves, globe valves, check valves, ball valves, butterfly valves, and regulating valves designed and manufactured for liquid hydrogen or cold hydrogen with a temperature range of -253°C to -29°C and not lower than the boiling point of hydrogen under standard atmospheric pressure. These valves are used for welded or flanged connections and have a nominal pressure not exceeding PN160 and a pressure rating not exceeding Class 900. This document specifies the classification and models, technical requirements, test methods, inspection rules, marking, packaging, transportation, and storage of low-temperature valves for hydrogen.
