CEN/TC 268 Cryogenic vessels and specific hydrogen technologies applications
European Norm
23.020.40 Cryogenic vessels | 23.040.70 Hoses and hose assemblies
This European Standard specifies the minimum requirements for the design, manufacture and testing of couplings for cryogenic service to be used for temporary connecting of flexible hoses to cryogenic vessels at the following operating conditions :
- design temperature range from - 270 ° C to + 65 ° C ;
- maximum nominal pressure : 80 bar ;
- nominal size (DN) from 10 to 100.
Permanent connections such as flanges and unions are not covered by this standard.
It is intended that the couplings should be designed, tested and marked for service at one of the generally accepted pressure e.g. PN 40. Couplings can then be selected with a PN equal to or greater than the maximum allowable pressure (PS) of the equipment for which they are to be used.
