Ukuhlolwa: Ngokuqhelekileyo, imibhobho yentsimbi yokuthutha ulwelo kufuneka ihlalutywe ukwakheka kweekhemikhali, uvavanyo lwe-tensile, uvavanyo lokucaba kunye novavanyo loxinzelelo lwamanzi. Ukongeza kwiimvavanyo ekufuneka zenziwe kwimibhobho yentsimbi yokuthutha ulwelo, imibhobho yentsimbi ye-GB5310, GB6479 kunye ne-GB9948 nayo iyafuneka ukuba iqhube uvavanyo lokwandiswa kunye novavanyo lwempembelelo; iimfuno zokuhlolwa kwemveliso kule mibhobho emithathu yentsimbi ingqongqo. Umgangatho we-GB6479 wenza iimfuno ezikhethekileyo zokuqina kwefuthe lobushushu obusezantsi bezinto. Ukongeza kwiimfuno zovavanyo ngokubanzi kwimibhobho yentsimbi yokuthutha ulwelo, imibhobho yentsimbi yomgangatho we-GB3087 nayo iyafuneka ukuba yenze uvavanyo lokugoba olubandayo. Ukongeza kwiimfuno zovavanyo oluqhelekileyo lwemibhobho yensimbi yokuthutha ulwelo, iipayipi zensimbi ze-GB / T8163 ezisemgangathweni zifuneka ukuba ziqhube uvavanyo lokwandiswa kunye novavanyo lokugoba olubandayo ngokwesivumelwano. Iimfuno zokuvelisa le mibhobho mibini azikho ngqongqo njengezintathu zokuqala. Ukuvelisa: Imibhobho yentsimbi ye-GB / T / 8163 kunye nemigangatho ye-GB3087 ininzi inyibilikiswa sisithando somlilo esivulekileyo okanye i-converter, kunye neengxenye zabo zokungcola kunye neziphene zangaphakathi zingaphezulu. I-GB9948 ubukhulu becala inyibilikiswa ziziko lombane. Uninzi lwabo longeze inkqubo yokucoca ngaphandle kwesithando somlilo, kwaye ukubunjwa kunye neziphene zangaphakathi zincinci. Imigangatho ye-GB6479 kunye ne-GB5310 ngokwazo ichaza iimfuno zokusulungekiswa ngaphandle kwesithando somlilo, kunye nezona nxalenye zincinci zokungcola kunye neziphene zangaphakathi, kunye nomgangatho ophezulu wezinto eziphathekayo. Amanqanaba omgangatho wokuvelisa le migangatho yemibhobho yentsimbi engentla ikwi-odolo ukusuka ezantsi ukuya phezulu: GB/T8163
(II) Imibhobho yentsimbi ephantsi engenamthungo kwisixhobo sokuvelisa i-petrochemical, intsimbi esetyenziswa ngokuqhelekileyo i-chromium-molybdenum kunye nemigangatho yentsimbi ye-chromium-molybdenum-vanadium yensimbi engenamthungo yi-GB9948 "Imibhobho yentsimbi engenamthungo yokuqhekeka kwepetroleum" GB6479 "Uxinzelelo oluphezulu lwentsimbi yesichumiso se-5 imibhobho ye-GB yensimbi engenamthungo" imibhobho yentsimbi ye-GB / T Seamless izixhobo ze-GB iibhoyila ezinoxinzelelo oluphezulu" I-GB9948 iqulethe i-chromium-molybdenum amabakala ezinto zentsimbi: 12CrMo, 15CrMo, 1Cr2Mo, 1Cr5Mo, njl. intsimbi ye-chromium-molybdenum kunye ne-chromium-molybdenum-vanadium izinto zentsimbi: i-15MoG, i-20MoG, i-12CrMoG, i-15CrMoG, i-12Cr2MoG, i-12Cr1MoVG, njl. Phakathi kwabo, i-GB9948 isetyenziswa ngokuqhelekileyo njengeemeko zokukhetha, kunye neemeko zokukhetha.
