Phakathi kwamapayipi amaningi, okusebenzayo kakhulu ipayipi lensimbi elingenamthungo, okuyipayipi eliqinile, hhayi nje ngenxa yobubanzi bezinkambu zokufaka isicelo kanye nobubanzi balo mbhobho, kodwa okubaluleke kakhulu ngenxa yekhwalithi ephezulu yepayipi lensimbi engenamthungo. .Khona-ke, ikhwalithi yepayipi yensimbi engenamthungo yisizathu sokuthi kungani lolu hlobo lwepayipi lungakhuthazwa futhi luthuthukiswe emkhakheni wezimboni.Izinga lamapayipi ensimbi angenasici lihle kakhulu, elinqunywa inqubo yokukhiqiza eyinkimbinkimbi yamapayipi ensimbi angenasici.Isici esikhulu kunazo zonke samapayipi ensimbi angenamthungo ukuthi udonga lwamapayipi alunawo ama-seams (lungakwazi ukumelana nokucindezela okukhulu), kuyilapho amapayipi avamile anezingqimba ezicacile.Ngenxa yobukhulu obuncane bepayipi yensimbi engenamthungo, lolu hlobo lwepayipi lungasetshenziswa futhi luthuthukiswe emkhakheni wezimboni.
Amapayipi ensimbi angenamthungo asetshenziswa kakhulu.Amapayipi ensimbi angenamthungo anenjongo evamile asongwa kusukela kunsimbi ye-carbon evamile noma insimbi yealloy enomphumela omkhulu kakhulu.I-carbon steel evamile ihlukaniswe ikakhulukazi:I-ASTM A106/A53 GR.B ipayipi lensimbi engenamthungo, I-API 5L GR.B ipayipi lensimbi elingenamthungo, ingxubevange steel ihlukaniswe ikakhulukazi: 15CrMo ingxubevange ipayipi Seamless steel, 30CrMo ingxubevange ipayipi Seamless steel, 42CrMo ingxubevange ipayipi nekhono,20Cr ingxubevange ipayipi Seamless steel, 40Cr ingxubevange ipayipi Seamless steel, 27SiMn ingxubevange yepayipi lensimbi engenamthungo.
Asetshenziswa kakhulu njengamapayipi noma izingxenye zesakhiwo zokudlulisa uketshezi.Ipayipi lensimbi elingenamthungo eliphakeme elikhiqizwa yilolu hlobo lwensimbi lisetshenziswa kakhulu kuma-hydraulic props, amasilinda egesi anengcindezi ephezulu, ama-boilers anengcindezi ephezulu, imishini kamanyolo, ukuqhekeka kwe-petroleum, imikhono ye-axle yemoto, izinjini zedizili, njll.
