Incazelo:ipayipi lensimbi lokushisa eliphansikuphakathi nendawoinsimbi yesakhiwo sekhabhoniAmapayipi ensimbi abandayo nashisayo nanezinga lokushisa eliphansi asebenza kahle, izakhiwo ezinhle zemishini, intengo ephansi kanye nemithombo ebanzi, ngakho-ke asetshenziswa kabanzi. Ubuthakathaka bawo obukhulu ukuthi izinto zokusebenza ezinokuqina okuphansi, usayizi omkhulu wesigaba kanye nezidingo eziphezulu akufanele zisetshenziswe.
Iipayipi lensimbi elingenamthungo elinokushisa okuphansiingasebenza endaweni ebanda kakhulu engu- - 45~- 110 ℃. Inzuzo evelele yepayipi lensimbi elingenamthungo elinokushisa okuphansi ukuthi lingasebenza endaweni ephansi kakhulu, okungenakuqhathaniswa nepayipi lensimbi elingenamthungo elivamile. Ipayipi lensimbi elingenamthungo elinokushisa okuphansi linamandla amahle nokuqina okuphansi, futhi lisetshenziswa kabanzi ekukhiqizweni kwemishini enamazinga okushisa aphansi kuphethiloli, amakhemikhali, umanyolo kanye neminye imboni enezinga lokushisa elisebenzayo elingu- - 45~- 110 ℃. Ngokuthuthuka kwezimboni ezifanele, izidingo zezinto azigcini nje ngokukhawulelwa ezidingweni eziyisisekelo njengezakhiwo zemishini kanye nezakhiwo zokushisela, kodwa futhi nezidingo zokumelana nokugqwala kwe-H2S kwamapayipi anamazinga okushisa aphansi.
Ipayipi lensimbi elingenamthungo elinokushisa okuphansikusebenza kubunjiniyela bamapayipi endaweni ephansi yokushisa. Kunezinqubo ezimbili: ukudweba okubandayo kanye nokugoqa okushisayo. Ngokombono womklamo wensimbi, ukwenza insimbi, ukugoqa, ukwelashwa kokushisa kanye nezinye izinqubo zepayipi lensimbi elingenamthungo elinokushisa okuphansi kufanele kulawulwe ngokuqinile ukuqinisekisa ukuthi ipayipi lensimbi elingenamthungo elinokushisa okuphansi linamandla amahle, ukuqina kanye nokumelana nokugqwala. Ngezidingo zobuchwepheshe zepayipi lensimbi elingenamthungo elinokushisa okuphansi, inhlangano yokukhiqiza kanye nezindleko zokukhiqiza zepayipi lensimbi kufanele kucatshangelwe ngokuphelele. Ukwakheka kwepayipi lensimbi elingenamthungo elinokushisa okuphansi kudinga ukuqinisekisa ukuthi umkhiqizo unamandla afanele, ukuqina okuphezulu kokushisa okuphansi, kanye nenqubo yokwelapha ukushisa elula Ukushibilika okuhle kanye nokumelana nokuqhekeka okubangelwa yi-hydrogen.
Izinga eliphezulu lepayipi lensimbi elingenamthungo elisezingeni eliphansi lokushisaI-ASTM A333- Ipayipi Lensimbi Elingenamthungo Nelihlanganisiwe Lensizakalo Yokushisa Okuphansi
Izinto zokushisa okuphansiipayipi lensimbi elingenamthungoimikhiqizo: 16Mn, 10MnDG, 09DG, 09Mn2VDG, 06Ni3MoDG, njll.
