Ipayipi lensimbi yekhabhoni, into eyisisekelo esetshenziswa kabanzi emkhakheni wezimboni, idlala indima ebalulekile ezimbonini ezifana nephethiloli, ubunjiniyela bamakhemikhali, kanye nokwakha. Amapayipi ensimbi yekhabhoni avamile ahlukaniswe kakhulu ngezinhlobo ezimbili:ipayipi lensimbi elingenamthungofuthiipayipi lensimbi elihlanganisiwe.
Ngokuphathelene nenqubo yokukhiqiza kanye nesakhiwo, ipayipi lensimbi elingenamthungo lakhiwa ngokugoqa noma ukukhipha okuhlanganisiwe, ngaphandle kwemithungo ehlanganisiwe. Linikeza amandla aphezulu kanye nokuqina okuphezulu, lingamelana nokucindezeleka okuphezulu kanye namazinga okushisa, futhi lifanele ukusetshenziswa okudinga izidingo zokuphepha kwamapayipi eziqinile.
Ngakolunye uhlangothi, ipayipi lensimbi elihlanganisiwe lenziwa ngamapuleti ensimbi ahlanganisiwe futhi ahlanganisiwe, anokunamathisela okukodwa noma ngaphezulu. Nakuba lokhu kunikeza ukusebenza kahle kokukhiqiza okuphezulu kanye nezindleko eziphansi, ukusebenza kwalo ngaphansi kokucindezeleka okuphezulu kanye nezimo ezimbi kakhulu kuphansi kancane kunokwepayipi elingenamthungo.
Kumapayipi ensimbi angenamthungo, i-Q235 kanye ne-A36 yizinhlobo ezidumile. Ipayipi lensimbi le-Q235 liyizinga lensimbi yesakhiwo sekhabhoni esetshenziswa kakhulu eShayina. Njengoba linamandla okukhiqiza angu-235 MPa, linikeza ukushibilika okuhle kakhulu kanye nokuguquguquka ngentengo engabizi. Lisetshenziswa kabanzi ekwakheni ukwesekwa kwesakhiwo, amapayipi oketshezi anomfutho ophansi, kanye nezinye izinhlelo zokusebenza, njengemipayipi yamanzi yokuhlala kanye nokwakhiwa kohlaka lwensimbi lwezakhiwo zefektri ezivamile.
Ipayipi lensimbi yekhabhoni le-A36iyizinga elijwayelekile lase-US. Amandla ayo okukhiqiza afana ne-Q235, kodwa inikeza amandla aphezulu okudonseka kanye nokuqina komthelela. Isetshenziswa kabanzi kumapayipi anengcindezi ephansi ekukhiqizweni kwemishini nasekukhiqizweni kwamafutha, njengokucubungula izingxenye ezincane zemishini kanye namapayipi kawoyela anengcindezi ephansi ezindaweni zikawoyela.
Ngepayipi lensimbi elihlanganisiwe,Ipayipi lensimbi elihlanganisiwe le-Q235futhi iyizinga elidumile. Ngenxa yezindleko zayo eziphansi kanye nokusebenza kwayo okuhle kakhulu kokushisela, ivame ukusetshenziswa kumaphrojekthi okudlulisa igesi edolobheni kanye nokudlulisa amanzi ngomfutho ophansi. Ngakolunye uhlangothi, ipayipi elihlanganisiwe le-A36 livame ukusetshenziswa kakhulu kumapayipi ezimboni anomfutho ophansi anezidingo ezithile zamandla, njengepayipi lokuthuthwa kwezinto ezinomfutho ophansi ezitshalweni ezincane zamakhemikhali.
| Ubukhulu Bokuqhathanisa | Ipayipi Lensimbi le-Q235 | Ipayipi Lensimbi Yekhabhoni le-A36 |
| Uhlelo Olujwayelekile | Izinga Likazwelonke LaseShayina (GB/T 700-2006 "Insimbi Yesakhiwo Sekhabhoni") | I-American Society for Testing and Materials (ASTM A36/A36M-22 "Ipuleti Lensimbi Yekhabhoni, Izimo, kanye Nezibha Zokusetshenziswa Kwesakhiwo") |
| Amandla Okukhiqiza (Okungenani) | 235 MPa (ukujiya ≤ 16 mm) | 250 MPa (kuyo yonke ububanzi bokujiya) |
| Ububanzi Bamandla Okuqina | 375-500 MPa | 400-550 MPa |
| Izidingo Zokuqina Komthelela | Ukuhlolwa komthelela okungu-40°C kuyadingeka kuphela kumamaki athile (isb., Q235D); akukho mfuneko ephoqelekile yamamaki avamile. | Izidingo: -18°C ukuhlolwa komthelela (izindinganiso ezingaphelele); ukuqina kokushisa okuphansi kungcono kancane kunezinga elijwayelekile le-Q235 |
| Izimo Eziyinhloko Zokusebenza | Ukwakhiwa kwezakhiwo (izakhiwo zensimbi, izisekelo), amapayipi amanzi/igesi anomfutho ophansi, kanye nezingxenye ezijwayelekile zemishini | Ukukhiqizwa kwemishini (izingxenye ezincane neziphakathi nendawo), amapayipi okucindezela okuphansi kwensimu kawoyela, amapayipi oketshezi oluphansi lwezimboni |
Sekukonke, amapayipi ensimbi angenamthungo nashibilikisiwe ngalinye linezinzuzo zalo. Lapho ethenga, amakhasimende kufanele acabangele izidingo zokucindezela kanye nokushisa kwesicelo esithile, kanye nesabelomali sawo, bese ekhetha ibanga elifanele, njenge-Q235 noma i-A36, ukuqinisekisa ikhwalithi nokuphepha kwephrojekthi.
