Isiqinisekiso sekhwalithi sangempela somkhiqizi wepayipi lensimbi ye-ST52
Insimbi engeyona ingxubevange ithathwa njengensimbi ejwayelekile yesakhiwo, ebonakala kakhulu ngamandla aqinile kanye nephuzu lokukhiqiza. Isetshenziselwa ukwakhiwa komphakathi, ubunjiniyela obungaphansi komhlaba, isakhiwo sebhuloho, isakhiwo sasolwandle, ukukhiqizwa kweziqukathi, ukukhiqizwa kwezimoto kanye nomshini.
Ibanga lensimbi ngokuvamile lakhiwa uhlamvu st, inani lesici lensimbi kanye nenkomba yekhwalithi. Ngokwesibonelo, St52-3. Ngebanga lensimbi elinezidingo ezithile zokukhetha zendlela ye-deoxidation, uphawu oluhambisanayo (U noma R) lubekwe phambi kwebanga lensimbi.
Isibonelo: ust37-2 noma rst37-2
Uhlobo oluncane lwe-st37-2 st37-3u st37-3n luthatha indawo yensimbi engama-20
I-St37 iwuphawu lwaseJalimane, kodwa iwuhlobo olujwayelekile kanye nemikhiqizo emincane eminingana.
Okufana ne-st37-2, st37-3u, st37-3n, rst-2, ust37-2, njll.
I-St37-2 iwuphawu lwensimbi ye-carbon structural eJalimane
Le nto ilingana ne-carbon structural steel Q235B (inombolo yomkhiqizo endala: a3-b) e-China.
Ngaphezu kwalokho, ngenxa yokuthi le nsimbi ifana nensimbi yaseChina esezingeni eliphakeme ye-carbon structural steel 20, ingashintshwa ngensimbi engama-20.
Ipayipi lensimbi engenamthungo enomfutho ophezulu kanye nepayipi likabhoyela elinomfutho omkhulu kuwuhlobo lwepayipi likabhoyela, eliyingxenye yepayipi lensimbi engenamthungo. Indlela yokukhiqiza iyafana neyepayipi elingenamthungo, kodwa kunezidingo eziqinile zebanga lensimbi elisetshenziswa ekwenzeni ipayipi lensimbi. Amashubhu e-boiler anengcindezi ephezulu avame ukusetshenziswa ngaphansi kokushisa okuphezulu nezimo zokucindezela okukhulu. Amashubhu kabhayela anomfutho ophakeme asetshenziswa ngokuyinhloko ukwenza amashubhu okushisa aphezulu, amashubhu okushisa kabusha, amapayipi omoya, amashubhu amakhulu esitimu, njll. amabhoyili anengcindezi ephezulu kanye nawomfutho ophezulu wegazi.
