| ib.Txoj kev deoxidation yog tsim raws li hauv qab no: FF: Ua tiav cov hlau uas muaj nitrogen khi cov ntsiab lus kom txaus los khi muaj nitrogen (xws li min. 0,020% tag nrho Al lossis 0,015% soluble Al). b.Tus nqi siab tshaj plaws rau nitrogen tsis siv yog tias cov tshuaj muaj pes tsawg leeg pom qhov tsawg kawg nkaus Al ntsiab lus ntawm 0,020% nrog qhov tsawg kawg nkaus Al / N piv ntawm 2: 1, lossis yog tias muaj lwm yam N-binding ntsiab.Cov ntsiab lus N-binding yuav tsum tau sau rau hauv Cov Ntaub Ntawv Tshawb Fawb. | ||||||||
Hydrostatic Test
Txhua qhov ntev ntawm cov yeeb nkab yuav tsum raug kuaj los ntawm cov chaw tsim khoom mus rau lub siab hydrostatic uas yuav tsim nyob rau hauv cov yeeb nkab phab ntsa ib qho kev ntxhov siab tsis pub tsawg tshaj 60% ntawm qhov tsawg kawg nkaus yield zog ntawm chav tsev kub.Lub siab yuav tsum tau txiav txim los ntawm qhov sib npaug hauv qab no:
P = 2st/D
Permissible variations In Weights and Dimensions
Txhua qhov ntev ntawm cov yeeb nkab yuav tsum tau ntsuas nyias thiab nws qhov hnyav yuav tsum tsis txhob sib txawv ntau dua 10% tshaj lossis 5.5% raws li nws qhov hnyav, suav nrog nws qhov ntev thiab nws qhov hnyav ntawm ib chav tsev ntev.
Sab nraud txoj kab uas hla yuav tsum tsis txhob sib txawv ntau tshaj ± 1% ntawm lub npe nominal sab nraud txoj kab uas hla
Phab ntsa thickness ntawm txhua qhov chaw yuav tsum tsis pub ntau tshaj 12.5% raws li cov phab ntsa thickness
