STORING OR DISTRIBUTING GASES OR LIQUIDS

Description

F17 encompasses systems, apparatus, and methods for the storage, handling, and distribution of gases and liquids under pressure or at cryogenic temperatures. This class covers gas cylinders, pressure vessels, pipelines, valves, regulators, safety devices, and integrated distribution networks for industrial, commercial, and domestic applications. Technologies include liquefied gas storage (such as LPG and cryogenic liquids), gas purification systems, and pressure control mechanisms. The class excludes specific applications of stored gases or liquids (such as fuel systems for internal combustion engines or refrigeration cycles, which are classified elsewhere) and focuses instead on the containment and flow management infrastructure itself.
