IBanga B kanye neBanga C amabanga amabili ahlukene ngaphansi kwezinga le-ASTM A500.
I-ASTM A500iyindinganiso ethuthukiswe yi-ASTM International yokufaka amashubhu esakhiwo se-carbon steel abandayo akhiwe ashiselwe futhi angenamthungo.
Okulandelayo, ake siwaqhathanise futhi siwaqhathanise ngezindlela ezehlukene ukuze siqonde ukuthi ikuphi ukufana nokuhluka kwawo.
Umehluko
I-ASTM A500 IBanga B no-C ihluke kakhulu ekwakhekeni kwamakhemikhali, izakhiwo eziqinile, nezindawo ezisetshenziswayo.
Umehluko Ekubunjweni Kwamakhemikhali
Ezingeni le-ASTM A500, kunezindlela ezimbili zokuhlaziya ukwakheka kwamakhemikhali ensimbi: ukuhlaziya okushisayo nokuhlaziywa komkhiqizo.
Ukuhlaziywa kokushisa kwenziwa ngesikhathi sokuncibilika kwensimbi.Inhloso yalo ukuqinisekisa ukuthi ukwakheka kwamakhemikhali ensimbi kuhlangabezana nezidingo zezinga elithile.
Ukuhlaziywa komkhiqizo, ngakolunye uhlangothi, kwenziwa ngemuva kokuba insimbi isivele yenziwe umkhiqizo.Le ndlela yokuhlaziya isetshenziselwa ukuqinisekisa ukuthi ukwakheka kwamakhemikhali omkhiqizo wokugcina kuhlangabezana nezidingo ezishiwo.
Akumangazi ukuthi i-carbon content yeBanga C iphansi kancane kunaleyo yeBanga B, okungase kusho ukuthi iBanga C linokuqina okungcono uma kushiselwa nokubunjwa.
Umehluko ku-Tensile Properties
Ibanga B: Ivamise ukuba nezinga eliphezulu le-ductility, eyivumela ukuthi inwebe ngokushuba ngaphandle kokuphuka, futhi ifanele izakhiwo ezidinga ukugoba okuthile noma ukuwohloka.
Ibanga C: Inamandla aphezulu okunyakazisa kanye nesivuno ngenxa yokwakheka kwamakhemikhali ayo, kodwa ingase ibe ne-ductile encane kune-Grade B.
Umehluko Kuhlelo Lokusebenza
Nakuba kokubili kusetshenziselwa izinhlelo zokusebenza zesakhiwo nokusekela, ukugcizelela kuhlukile.
Ibanga B: Ngenxa yezakhiwo zayo ezingcono zokushisela nokwakha, kuvame ukusetshenziselwa izakhiwo zokwakha, ukwakhiwa kwebhuloho, izisekelo zokwakha, njll., ikakhulukazi uma izakhiwo zidinga ukushiselwa futhi zigobe.
Ibanga C: Ngenxa yamandla ayo aphezulu, ivame ukusetshenziswa kuzinhlelo zokusebenza ezingaphansi kwemithwalo ephakeme, njengokwakhiwa kwezimboni, izakhiwo zokusekela imishini esindayo, njalonjalo.
Ukujwayelana
Nakuba iBanga B kanye neBanga C ehluka ngezindlela ezimbalwa, futhi abelana ngezici ezifanayo.
I-Same Cross-section Shape
Izimo zesigaba esingenalutho ziyindilinga, isikwele, unxande, kanye ne-oval.
Ukwelashwa Kokushisa
Konke kuvumela insimbi ukuthi inciphise ukucindezeleka noma ikhishwe.
Izinhlelo Zokuhlola Ezifanayo
Kokubili iBanga B kanye no-C kudingeka ukuthi ihlangabezane nezidingo ze-ASTM A500 zokuhlaziya ukushisa, ukuhlaziya umkhiqizo, ukuhlolwa kwe-tensile, Ukuhlolwa Kokucaba, Ukuhlolwa Kwe-Flaring, kanye Nokuhlolwa Kwe-Wedge Crush.
Ukubekezelela Okufanayo Kobukhulu
Isibonelo sesigaba esiyindilinga esingenalutho.
Ekukhetheni ukuthi uzosebenzisa ishubhu ye-ASTM A500 yeBanga B noma yeBanga C, izidingo zangempela zobunjiniyela kanye nokusebenza ngempumelelo kwezindleko kufanele kubhekwe.
Isibonelo, ezakhiweni ezingadingi amandla aphezulu kodwa ukuqina okuhle, iBanga B lingaba ukukhetha ukonga kakhulu.Kumaphrojekthi adinga amandla engeziwe namandla okuthwala umthwalo, iBanga C lihlinzeka ngokusebenza okudingekayo, nakuba ngezindleko eziphakeme.
