Uhlolo: Ngokubanzi, imibhobho yentsimbi yokuthutha ulwelo kufuneka ihlolwe ngokwemichiza, uvavanyo lokutsalwa, uvavanyo lokuthamba kunye novavanyo loxinzelelo lwamanzi. Ukongeza kwiimvavanyo ekufuneka zenziwe kwimibhobho yentsimbi yokuthutha ulwelo, imibhobho yentsimbi ye-GB5310, GB6479 kunye ne-GB9948 nayo iyafuneka ukuze ivavanywe ukwandiswa kunye novavanyo lwempembelelo; iimfuno zokuhlolwa kokuveliswa kwezi mibhobho zintathu zentsimbi zingqongqo kakhulu. Umgangatho we-GB6479 ukwanika iimfuno ezikhethekileyo zokuqina kwempembelelo ephantsi kobushushu. Ukongeza kwiimfuno zovavanyo ngokubanzi zemibhobho yentsimbi yokuthutha ulwelo, imibhobho yentsimbi yomgangatho we-GB3087 nayo iyafuneka ukuze ivavanywe ngokubandayo. Ukongeza kwiimfuno zovavanyo ngokubanzi zemibhobho yentsimbi yokuthutha ulwelo, imibhobho yentsimbi yomgangatho we-GB/T8163 kufuneka ivavanywe ngokukhula kunye novavanyo lokugoba ngokubandayo ngokwesivumelwano. Iimfuno zokuvelisa kwezi mibhobho zimbini azingqongqo njengezintathu zokuqala. Ukuvelisa: Imibhobho yentsimbi yemigangatho ye-GB/T/8163 kunye ne-GB3087 inyibilikiswa kakhulu sisithando somlilo okanye i-converter, kwaye izinto zayo zokungcola kunye neziphene zangaphakathi zingaphezulu kakhulu. I-GB9948 inyibilikiswa kakhulu sisithando sombane. Uninzi lwazo longeze inkqubo yokucoca ngaphandle kwesithando somlilo, kwaye ukwakheka kunye neziphene zangaphakathi zincinci kakhulu. Imigangatho ye-GB6479 kunye ne-GB5310 ngokwayo ichaza iimfuno zokucoca ngaphandle kwesithando somlilo, kunye nezinto ezingangcolanga kakhulu kunye neziphene zangaphakathi, kunye nomgangatho ophezulu wezinto. Amanqanaba omgangatho wokuvelisa wemigangatho yepayipi yentsimbi engentla alandelelana ukusuka kwesezantsi ukuya kwephezulu: GB/T8163
(II) Iipayipi zentsimbi engenamthungo zentsimbi e-alloy ephantsi Kwizixhobo zemveliso ye-petrochemical, imigangatho yepayipi yentsimbi engenamthungo ye-chromium-molybdenum esetyenziswa rhoqo yi-GB9948 "Iipayipi zentsimbi ezingenamthungo zokuqhekeka kwepetroleum" GB6479 "Iipayipi zentsimbi ezingenamthungo eziphezulu zezixhobo zesichumiso" GB/T5310 "Iipayipi zentsimbi ezingenamthungo zeebhoyila ezinoxinzelelo oluphezulu" GB9948 iqulethe amanqanaba ezinto zentsimbi ye-chromium-molybdenum: 12CrMo, 15CrMo, 1Cr2Mo, 1Cr5Mo, njl. GB6479 iqulethe amanqanaba ezinto zentsimbi ye-chromium-molybdenum: 12CrMo, 15CrMo, 1Cr5Mo, njl. GB/T5310 iqulethe amanqanaba entsimbi ye-chromium-molybdenum kunye namanqanaba ezinto zentsimbi ye-chromium-molybdenum-vanadium: 15MoG, 20MoG, 12CrMoG, 15CrMoG, 12Cr2MoG, 12Cr1MoVG, njl. Phakathi kwazo, i-GB9948 isetyenziswa kakhulu, kwaye iimeko zokukhetha zinje ngasentla.
