I-ASTM A106: Imibhobho yentsimbi yekhabhoni engenamthungo efanelekileyo kwinkonzo yobushushu obuphezulu, yahlulwe yaba yiGrade A, B, kunye no-C, esetyenziswa kakhulu kwimibhobho yeoyile, yokuhambisa igesi yendalo kunye namashishini eekhemikhali.
I-ASTM A519: Isebenza kwiibhari zentsimbi yekhabhoni ezichanekileyo kunye nemibhobho yokulungisa, kunye neemfuno ezingqongqo zokunyamezelana.
2. Imibhobho yentsimbi yekhabhoni edibeneyo
I-ASTM A500: Isebenza kwisikwere esidityanisiweyo esenziwe ngobandayo nesingenamthungo,uxandekunye neminye imibhobho yentsimbi eyakhiwe ngendlela emile okwesakhiwo, esetyenziswa kakhulu kwizakhiwo zokwakha.
I-ASTM A501: Isebenza kwimibhobho yesinyithi ejijekileyo eshushu nengenamthungo, exande kunye neminye imilo yesakhiwo.
I-ASTM A513: Isebenza kumbaneimibhobho yentsimbi ejikelezileyo edityanisiweyo, esetyenziswa kakhulu kwi-machining kunye nezicelo zesakhiwo.
3. Imibhobho yentsimbi yekhabhoni yeebhoyila kunye nee-superheaters
I-ASTM A179: Isebenza kwiipayipi zebhoyila zentsimbi ezitsalwa ngekhabhoni engaphantsi, ezifanelekileyo ukusetyenziswa ngomphunga oxinzelelweyo.
I-ASTM A210: Isebenza kwiipayipi zebhoyila zentsimbi yekhabhoni engenamthungo, ezahlulwe zibe ziiklasi ezine: A1, A1P, A2, kunye ne-A2P, ezisetyenziswa kakhulu kwiibhoyila ezinoxinzelelo oluphakathi noluphantsi.
I-ASTM A335: Isebenza kwiipayipi zenkonzo yobushushu obuphezulu zentsimbi ye-ferritic alloy engenamthungo, ezahlulwe ngokwamanqanaba amaninzi, njenge-P1, i-P5, njl.njl., ezifanelekileyo kwiipayipi zobushushu obuphezulu kumashishini e-petrochemical kunye namandla.
4. Imibhobho yentsimbi yekhabhoni yemithombo yeoyile negesi
I-ASTM A252: Isebenza kwi-spiral seam submear arcimibhobho yentsimbi edityanisiweyokwiinqwaba, ezisetyenziswa kakhulu ekwakheni amaqonga angaselunxwemeni.
I-ASTM A506: Isebenza kwimibhobho yentsimbi eqinileyo ene-alloy ephantsi, efanelekileyo kwimveliso yezixhobo zeoyile negesi.
I-ASTM A672: Isebenza kwimibhobho yesinyithi ye-silicon ye-carbon manganese enamandla aphezulu, ifanelekile kwizicelo ezifuna amandla aphezulu.
I-API Spec 5LNangona ingenguwo umgangatho we-ASTM, ngumgangatho owamkelekileyo kwihlabathi liphela wemibhobho yentsimbi yemibhobho yeoyile negesi, ogubungela iintlobo ezininzi zemibhobho yentsimbi yekhabhoni.
5. Imibhobho yentsimbi yekhabhoni yeenjongo ezikhethekileyo
I-ASTM A312: Isebenza kwimibhobho yentsimbi engagqwaliyo engenamthungo nedibeneyo. Nangona ikakhulu yenzelwe intsimbi engagqwaliyo, ikwabandakanya nezinye iinkcukacha zentsimbi yekhabhoni.
I-ASTM A795: Isebenza kwiibhilethi zentsimbi yekhabhoni kunye neebhilethi zentsimbi ye-alloy, iibhilethi ezijikelezileyo kunye neemveliso zazo ezenziwe ngokuphoswa okuqhubekayo kunye nokugqunywa, ezifanelekileyo kwiindawo ezithile zoshishino.
Indlela yokukhetha umgangatho ofanelekileyo we-ASTM
Ukukhetha umgangatho ofanelekileyo we-ASTM kuxhomekeke kwiimfuno ezithile zesicelo:
Indawo yokusetyenziswa: Cinga ngezinto ezifana nobushushu bokusebenza, iimeko zoxinzelelo, kunye nokubakho kwezixhobo ezibangela ukubola.
Iimpawu zoomatshini: Chonga amandla amancinci okuvelisa, amandla okutsalwa kunye nezinye izalathisi eziphambili.
Ukuchaneka kobukhulu: Kwezinye iinkqubo zomatshini okanye zokuhlanganisa ngokuchanekileyo, kunokufuneka ukunyamezela ububanzi bangaphandle kunye nobukhulu bodonga obulawulwa ngokungqongqo.
Unyango lomphezulu: Nokuba kufuneka i-hot-dip galvanizing, ipeyinti okanye ezinye iindlela zonyango lokuthintela ukugqwala.
