GAS-HOLDERS OF VARIABLE CAPACITY

Description

F17B covers gas storage devices with adjustable or variable internal volume, designed to accommodate fluctuating gas quantities while maintaining controlled pressure conditions. These systems typically employ movable walls, pistons, floating elements, or collapsible chambers to expand or contract based on gas demand and supply. Applications include gas holders for industrial distribution networks, buffer tanks in manufacturing processes, and pressure regulation systems where constant volume storage is impractical. This classification excludes fixed-capacity gas containers and pressure vessels that maintain constant volume (covered by F17C).
