This publication covers flexible hoses with nominal diameters of 1 in (25 mm) through 4 in (102 mm). 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 guide 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.
