Amalungiselelo afanelekileyo kuzwelonkeiflangeumgangatho "i-GB/T9124-2010 yeeMeko zobuGcisa kwiiFlange zeMibhobho yentsimbi":

3.2.1 Iiflange ezineengcinezelo ezibizwa ngokuba yi-PN2.5-PN16 Class150, i-carbon steel low, kunye ne-austenitic stainless steel forgings zivumelekile ukuba zibe yi-Class I forgings (ubunzima buvavanywa ngesiqhekeza).

3.2.2 Ukuba le miqathango ilandelayo ifezekisiwe, ukufogiswa kweeflange kuya kuhlangabezana neemfuno zeKlasi III okanye ngaphezulu kokufogina (isampula yokuhlolwa kwe-tensile kunye novavanyo lwe-ultrasonic nganye nganye):

1. I-Forgings yeeflange ezinoxinzelelo oluncinci ≥PN100 kunye ne-≥Class600;

2. I-Chromium-molybdenum i-forgings yensimbi ye-flanges kunye noxinzelelo lwegama ≥PN63 kunye ne-≥Class300;

3. I-Ferrite forgings ye-flanges kunye noxinzelelo lwegama ≥ PN25 kunye neKlasi ≥ 300 kunye nokushisa okusebenzayo ≤ -20 ° C.

3.2.3 Okunye ukufogiswa kweflange kufuneka kungqinelane neemfuno zeBakala II okanye ngaphezulu kwe forgings (ukuhlolwa kwendawo nokuzoba).
