GB/T 31481-2015

This standard provides guidance for assessing the compatibility between metallic and non-metallic materials and the gases stored in cryogenic vessels, specifically for applications involving extremely low temperatures. It is applied in the design, material selection, and safety evaluation of cryogenic containers used in industries such as liquefied natural gas (LNG), industrial gas storage, and aerospace. The standard helps prevent material degradation, embrittlement, or chemical reactions that could compromise vessel integrity during long-term service.
