CGA G-6.6-2022
Standard for Carbon Dioxide Bulk Transfer Hoses
This publication covers flexible hoses with inside diameters of 1 in (25 mm) or larger. Hoses for these applications have a normal operating pressure between 125 psi and 400 psi (860 kPa and 2760 kPa) and a maximum allowable working pressure (MAWP) of at least 450 psi (3100 kPa). These hoses shall be designed to operate in a temperature range between –65 °F and 125 °F (–54 °C and 51.7 °C). This publication is prepared as a standard for manufacturers and users of carbon dioxide hoses and represents the best currently available industry practice. Information on carbon dioxide can be found in CGA G-6, Carbon Dioxide [2]. NOTE—This publication does not include hoses used for filling uninsulated cylinders (e.g., DOT 3A), insulated cylinders (e.g., DOT 4L), or small stationary insulated containers (i.e., micro or mini-bulk).
