GB5310yikhowudi esemgangathweni yomgangatho wesizwe saseTshayina othi "Iipayipi zeNtsimbi ezingenamthungo zeIibhoyila zoxinzelelo oluphezulu", echaza iimfuno zobugcisa zemibhobho yentsimbi engenamthungo yeebhoyila ezinoxinzelelo oluphezulu kunye nemibhobho yomphunga. Umgangatho we-GB5310 ugubungela iintlobo ngeentlobo zemigangatho yentsimbi ukuhlangabezana neemfuno ezahlukeneyo zesicelo. Ezi zilandelayo zezinye zemigangatho eqhelekileyo kunye namashishini okusetyenziswa kwazo:

20G: I-20G yenye yezona ntlobo zisetyenziswa kakhulu kwi-GB5310, kunye nezinto eziphambili zekhabhoni, i-manganese kunye ne-silicon. Ineempawu ezintle zoomatshini kunye neempawu zokuwelda, kwaye isetyenziselwa kakhulu ukuvelisa izinto ezibalulekileyo ezifana neendonga ezipholisiweyo ngamanzi, ii-superheaters, ii-economizers kunye needrama kwiibhoyila zesikhululo samandla.

15CrMoG: Le ntsimbi ine-chromium kunye ne-molybdenum, kwaye inamandla aphezulu obushushu obuphezulu kunye nokumelana ne-oxidation. Iipayipi zentsimbi ezingenamthungo ze-15CrMoG zihlala zisetyenziselwa ukwenza iipayipi zomphunga ezinobushushu obuphezulu kunye noxinzelelo oluphezulu, ii-headers kunye nee-conduits, njl.njl., kwaye zisetyenziswa kakhulu kumashishini e-petrochemical kunye namandla.

12Cr1MoVG: Iqulethe izinto eziphezulu ze-chromium, i-molybdenum kunye ne-vanadium, kunye nokusebenza kakuhle kobushushu obuphezulu kunye nozinzo lwexesha elide. Iipayipi zentsimbi ezingenamthungo zale nqanaba zihlala zisetyenziswa kwiibhoyila ezinobushushu obuphezulu kunye noxinzelelo oluphezulu kunye nezixhobo zamandla enyukliya, ngakumbi izitshintshi zobushushu, iipayipi zomphunga, njl.njl.

Ezi ntlobo zahlukeneyo zeepayipi zentsimbi ezingenamthungo zisetyenziswa kakhulu ekwenzeni izinto ezibalulekileyo kwiindawo ezinobushushu obuphezulu kunye noxinzelelo oluphezulu ezifana namandla, i-petrochemical, kunye namandla enyukliya ngenxa yokwakheka kwazo okwahlukileyo kweekhemikhali kunye neempawu zoomatshini. Ngokukhetha uhlobo olufanelekileyo lwentsimbi, ukhuseleko kunye nokuzinza kwezixhobo phantsi kweemeko zokusebenza ezinzima kunokuqinisekiswa, kwaye ubomi benkonzo bunokwandiswa.
