Intshayelelo: Imibhobho yentsimbi ye-alloy engenamthungo iyinxalenye ebalulekileyo kwishishini lebhoyila, ibonelela ngobushushu obuphezulu kunye nezisombululo ezichasene noxinzelelo kwizicelo ezahlukeneyo. Le mibhobho ihambelana nemigangatho engqongqo ebekwe yi-ASTM A335, enamabanga anjeP5, P9, kunye neP11, ukuqinisekisa ukusebenza okuphezulu, ukuqina, kunye nokuthembeka kwimisebenzi yebhoyili.

Imigangatho ye-ASTM A335: I-ASTM A335 luphawu olugubungela umbhobho we-ferritic alloy-steel engenamthungo kwinkonzo yobushushu obuphezulu. Yamkelwa ngokubanzi kwaye yamkelwa kwishishini lebhoyila ngenxa yeemfuno zayo ezingqongqo kwiipropathi zoomatshini, ukwakheka kweekhemikhali, kunye neenkqubo zovavanyo. Le migangatho ibalulekile ekuqinisekiseni umgangatho kunye nokhuseleko lwemibhobho yensimbi ye-alloy esetyenziswe kuyoIbhoyila yoxinzelelo oluphezulu kunye nobushushu obuphezuluiinkqubo.

Izinto eziphathekayo kunye namaBanga: Imibhobho yensimbi ye-alloy ifumaneka kumabakala ahlukeneyo, kuquka i-P5, i-P9, kunye ne-P11, nganye yenzelwe ukuhlangabezana neemfuno ezithile zokushisa kunye noxinzelelo. I-P5 inika ukuxhathisa okugqwesileyo kwi-corrosion, iyenza ilungele ukumodareyitha kwizicelo zobushushu obuphezulu. I-P9 yaziwa ngamandla ayo akhethekileyo kunye nokuqina, iyenza ilungele imeko yebhoyila. I-P11 iyazingca ngokunyusa amandla okuqina kunye nokuxhathisa ubushushu, iyenza ilungele izicelo zobushushu obuphezulu.

Izinto eziluncedo: Imibhobho yentsimbi engenamthungo yealloyi ineenzuzo ezininzi ezenza zibe lolona khetho lukhethwayo kushishino lwebhoyila. Okokuqala kunye neyona nto iphambili, ukwakhiwa kwabo okungenamthungo kuphelisa umngcipheko wokuvuza, ukuqinisekisa ukusebenza okukhuselekileyo kunye nokusebenza kakuhle kwebhoyili. Izinto ezixutywayo kule mibhobho ziphakamisa ukuchasana kwe-oxidation kunye nokulinganisa, ukugcina ukunyaniseka kwesakhiwo nakwiimeko ezinzima. Ikhono lemibhobho yokumelana noxinzelelo oluphezulu kunye nokuguquguquka kweqondo lokushisa ngaphandle kokuguqulwa okanye ukungaphumeleli kunegalelo kubomi babo benkonzo ende kunye neemfuno zokugcinwa okuphantsi.

Izicelo: Imibhobho yentsimbi engenamthungo, intlanganisoImigangatho ye-ASTM A335, fumana ukusetyenziswa ngokubanzi kwibhoyila izicelo ezahlukeneyo. Ngokuqhelekileyo baqeshwe kwizityalo zokuvelisa amandla, apho basebenza njengezinto ezibalulekileyo kwii-superheaters, izifudumezi, kunye neendonga zamanzi. Ishishini leoli kunye negesi likwaxhomekeke kule mibhobho kwimibhobho yomphunga kunye neeyunithi zokulungisa ubushushu obuphezulu. Ukongeza, zisetyenziselwa ukucokisa kunye nezityalo zepetrochemical kwizicelo ezifuna ubushushu obuphezulu kunye nokumelana noxinzelelo.

Isiphelo: Ukuqukumbela, imibhobho yentsimbi engenamthungo ehambelanayoImigangatho ye-ASTM A335kunye namabakala P5, P9, kunye P11 abonelela ngezisombululo eziyimfuneko kushishino lwebhoyila. Ngeempawu zabo ezikhethekileyo, le mibhobho iqinisekisa ukusebenza kwebhoyili ekhuselekileyo kunye nethembekileyo, okwenza kube yinto ekhethiweyo yokushisa okuphezulu kunye noxinzelelo oluphezulu. Ukusetyenziswa kwazo ngokubanzi kumacandelo ahlukeneyo emizi-mveliso kungqina ukuthembeka kwazo, ukuqina, kunye nokukwazi ukumelana neemeko eziqatha, nto leyo ezenza zibe yinxalenye yenkqubo yebhoyila yanamhlanje.
