For a 100,000 cubic meter LNG skid-mounted LNG liquefaction unit, what GB standard is used as the criterion for gas tightness?
The airtightness qualification standards for 100,000 cubic meter LNG skid-mounted LNG liquefaction units are usually based on GB 18442-2022 Natural Gas Liquids – Storage Tanks. This standard covers the design, manufacturing, and inspection requirements for liquefied natural gas storage tanks, ensuring that the equipment meets regulatory requirements in terms of safety and environmental protection. You can refer to this national standard to view the specific airtightness testing requirements. .
As I understand it, what you want to ask about is the airtightness acceptance criteria for the skid units of liquefaction equipment; these actually relate to process pipelines, and the relevant standard is GB50184, the Construction Quality Standard for Industrial Metal Piping Projects, or GB50540, which is the construction standard for process pipelines in natural gas stations. If you need to refer to the American standards, they are not available; ASME31.3 only covers pressure testing aspects, while the Chinese standards provide more detailed regulations in this regard!
