Ipayipi lensimbi ye-Carbon, into eyisisekelo esetshenziswa kabanzi emkhakheni wezimboni, idlala indima ebalulekile ezimbonini ezifana ne-petroleum, ubunjiniyela bamakhemikhali, nezokwakha. Amapayipi ensimbi ajwayelekile ahlukaniswe ngokuyinhloko abe yizinhlobo ezimbili:ipayipi lensimbi engenamthungofuthiipayipi lensimbi elishiselwe.
Ngokuya ngenqubo yokukhiqiza kanye nesakhiwo, ipayipi lensimbi engenamthungo lakhiwa ngokugoqa okubalulekile noma ukukhishwa ngaphandle, ngaphandle kwemithungo ehlanganisiwe. Inikeza amandla aphezulu kanye nokuqina, ingakwazi ukumelana nezingcindezi eziphezulu namazinga okushisa, futhi ifanele izinhlelo zokusebenza ezidinga izidingo zokuphepha zamapayipi aqinile.
Ngakolunye uhlangothi, ipayipi lensimbi elishiselwe, lenziwa ngokugoqa kanye nokushisela amapuleti ensimbi, anensimbi eyodwa noma ngaphezulu. Nakuba lokhu kunikeza ukusebenza kahle kokukhiqiza okuphezulu kanye nezindleko eziphansi, ukusebenza kwayo ngaphansi kwengcindezi ephezulu kanye nezimo ezidlulele kungaphansi kancane kunaleyo yepayipi elingenamthungo.
Kumapayipi ensimbi angenamthungo, i-Q235 ne-A36 amamaki adumile. I-Q235 steel pipe iyibanga elivame ukusetshenziswa le-carbon structural steel eChina. Ngamandla okukhiqiza angu-235 MPa, inikeza ukushisela okuhle kakhulu kanye ne-ductility ngentengo ethengekayo. Isetshenziswa kabanzi ekwakheni ukwesekwa kwesakhiwo, amapayipi amanzi anomfutho ophansi, nezinye izinhlelo zokusebenza, njengamapayipi okuphakelwa kwamanzi okuhlala kanye nokwakhiwa kohlaka lwensimbi lwezakhiwo zefekthri ezijwayelekile.
A36 carbon steel pipeiyibanga elijwayelekile lase-US. Amandla ayo okukhiqiza afana ne-Q235, kodwa inikeza amandla aphakeme okuqina kanye nokuqina komthelela. Isetshenziswa kakhulu kumapayipi anengcindezi ephansi ekukhiqizeni imishini nasekukhiqizeni uwoyela, njengokucutshungulwa kwezingxenye ezincane zemishini kanye namapayipi kawoyela anengcindezi ephansi ezindaweni zikawoyela.
Okwepayipi lensimbi elishiselwe,Q235 ashiselwe ipayipi lensimbifuthi yibanga elidumile. Ngenxa yezindleko zayo eziphansi nokusebenza okuhle kakhulu kwe-welding, ivame ukusetshenziswa ekudluliselweni kwegesi yedolobha kanye namaphrojekthi okuhambisa amanzi anengcindezi ephansi. Ngakolunye uhlangothi, ipayipi elishiselwe i-A36, livame ukusetshenziswa kakhulu kumapayipi ezimboni anengcindezi ephansi enezidingo ezithile zamandla, njengamapayipi okuthutha impahla enengcindezi ephansi ezitshalweni zamakhemikhali ezincane.
| Izilinganiso zokuqhathanisa | Ipayipi lensimbi Q235 | Ipayipi Lensimbi Lekhabhoni le-A36 |
| Isistimu Ejwayelekile | I-China National Standard (GB/T 700-2006 "Carbon Structural Steel") | I-American Society for Testing and Materials (ASTM A36/A36M-22 "Carbon Steel Plate, Shapes, and Bars for Strictural Use") |
| Amandla Okukhiqiza (Okungenani) | 235 MPa (ubukhulu ≤ 16 mm) | 250 MPa (kulo lonke ububanzi obugcwele bokujiya) |
| I-Tensile Strength Range | 375-500 MPa | 400-550 MPa |
| I-Impact Toughness Izidingo | Ukuhlolwa komthelela okungu--40°C kuyadingeka kuphela kumabanga athile (isb, Q235D); asikho isidingo esiyisibopho samabanga avamile. | Izimfuneko: -18°C ukuhlolwa komthelela (izindinganiso eziyingxenye); izinga lokushisa eliphansi eliqinile lingcono kancane kunamamaki avamile e-Q235 |
| Izimo Zokusebenza Eziyinhloko | Ukwakhiwa kwe-civil (izakhiwo zensimbi, izisekelo), amapayipi amanzi/igesi anengcindezi ephansi, kanye nezingxenye ezijwayelekile zemishini | Ukukhiqizwa kwemishini (izingxenye ezincane nezinosayizi ophakathi), amapayipi okucindezela okuphansi kwe-oilfield, amapayipi amanzi anomfutho ophansi wezimboni |
Sekukonke, amapayipi ensimbi angenamthungo futhi ashiselwe ngalinye linezinzuzo zalo. Lapho uthenga, amakhasimende kufanele acabangele ingcindezi nezimfuneko zokushisa zohlelo oluthile, kanye nesabelomali sawo, futhi akhethe ibanga elifanele, njenge-Q235 noma i-A36, ukuze aqinisekise ikhwalithi nokuphepha kwephrojekthi.
