Incazelo:izinga lokushisa eliphansi lensimbi ipayipiiphakathiinsimbi yesakhiwo se-carbon. Amapayipi ensimbi abandayo futhi ashisayo futhi aphansi asebenza kahle, izakhiwo ezinhle zemishini, amanani aphansi kanye nemithombo ebanzi, ngakho-ke asetshenziswa kabanzi. Ubuthakathaka bayo obukhulu ukuthi ama-workpieces anokuqina okuphansi, ubukhulu besigaba esikhulu kanye nezidingo eziphezulu akufanele zisetshenziswe.
Iizinga lokushisa eliphansi lensimbi engenamthungo ipayipiingasebenza endaweni ebanda kakhulu - 45~-110 ℃. Inzuzo evelele yepayipi yensimbi engenamthungo esezingeni eliphansi ukuthi ingasebenza endaweni ephansi kakhulu, engenakuqhathaniswa nepayipi evamile yensimbi engenamthungo. Ipayipi lensimbi elingenamthungo elisezingeni eliphansi linamandla amahle kanye nokuqina kwezinga lokushisa eliphansi, futhi lisetshenziswa kabanzi ekwenzeni imishini yezinga lokushisa eliphansi ku-petroleum, amakhemikhali, umanyolo nezinye izimboni ezinokushisa okusebenzayo okungu-45~-110 ℃. Ngokuthuthukiswa kwezimboni ezifanele, izidingo zezinto zokwakha azikhawulelwe kuphela ezidingweni eziyisisekelo ezifana nezakhiwo zemishini kanye nezakhiwo zokushisela, kodwa futhi nezidingo zokumelana nokugqwala kwe-H2S kwamapayipi aphansi okushisa.
Ipayipi lensimbi engenamthungo esezingeni eliphansisisebenza kubunjiniyela bamapayipi endaweni yokushisa ephansi. Kunezinqubo ezimbili: umdwebo obandayo kanye nokugoqa okushisayo. Ngokombono womklamo wensimbi, i-steelmaking, rolling, treatment treatment kanye nezinye izinqubo zepayipi lensimbi engenamthungo esezingeni eliphansi kufanele ilawulwe ngokuqinile ukuze kuqinisekiswe ukuthi izinga lokushisa eliphansi lensimbi engenamthungo linamandla amahle, ukuqina nokumelana nokugqwala. Ngezidingo zobuchwepheshe zepayipi lensimbi engenamthungo esezingeni eliphansi, inhlangano yokukhiqiza kanye nezindleko zokukhiqiza zepayipi lensimbi kufanele kucatshangelwe ngokuphelele. Idizayini yokuqamba yepayipi lensimbi engenamthungo enezinga lokushisa eliphansi lidinga ukuqinisekisa ukuthi umkhiqizo unamandla afanele, ukuqina okuphezulu kwethempelesha ephansi, kanye nenqubo elula yokwelashwa kokushisa Ukushisela okuhle nokumelana nokuqhekeka okubangelwa i-hydrogen.
Izinga eliphezulu lokushisa eliphansi lensimbi ipayipi nekhonoI-ASTM A333- Ipayipi Lensimbi Elingenamthungo futhi Elishiselwe Yesevisi Yezinga Lokushisa Eliphansi
Impahla yezinga lokushisa eliphansiipayipi lensimbi engenamthungoimikhiqizo: 16Mn, 10MnDG, 09DG, 09Mn2VDG, 06Ni3MoDG, njll.
