Ibhoyila yoxinzelelo oluphezuluizixhobo zentsimbi engqinibeniziveliswa kwibhobho yebhoyila yoxinzelelo oluphezulu kunye neepleyiti
Uxinzelelo oluphezulu kunye nemibhobho yentsimbi yebhoyila yomphunga. Le mibhobho yebhoyili isebenza phantsi kobushushu obuphezulu kunye noxinzelelo oluphezulu. Umbhobho uya kuba ne-oxidized kunye ne-corrod phantsi kwesenzo se-high-temperature flue gas kunye nomphunga wamanzi, ngoko ke umbhobho wensimbi kufuneka ube nokuqina okuphezulu, ukuxhathisa okuphezulu kwe-oxidation, kunye nokuzinza okulungileyo kombutho.
Imibhobho yentsimbi engenamthungo yokugrumba ijoloji kunye nolawulo lokwemba ioli; sebenzisa izixhobo zokugrumba ukugrumba amaqula ukuze kuhlolwe ubume bamatye angaphantsi komhlaba, amanzi aphantsi komhlaba, i-oyile, irhasi yendalo, kunye nemithombo yezimbiwa.
Imibhobho yentsimbi engenamthungo yolawulo lokomba lwejoloji kunye nokugrumba i-oyile zezona zixhobo ziphambili zokomba, ezibandakanya ikakhulu umbhobho wangaphandle ongundoqo, undoqo wetyhubhu yangaphakathi, i-casing, i-drill pipe, njl. , iimeko zokusebenza zintsonkothe ​​kakhulu. Umbhobho wokugrumba uphantsi koxinzelelo olufana noxinzelelo, ukucinezelwa, ukugoba, ukushukuma, kunye nomthwalo wempembelelo engalinganiyo, kwaye ukwaphantsi kodaka namatye. Ngoko ke, izinto zombhobho ziyafuneka Kufuneka zibe namandla okwaneleyo, ukuqina, ukuxhatshazwa kokugqoka, kunye nokuqina kwempembelelo. Insimbi esetyenziselwa imibhobho yensimbi iboniswa yi "DZ" (i-Geological Chinese Pinyin prefix) kunye nenombolo enye yokumela isivuno sentsimbi. Imibhobho yentsimbi ihanjiswa kwimeko yokushisa.
Imibhobho eqhekezayo yepetroleum: imibhobho engenamthungo yemibhobho yesithando somlilo, imibhobho yokutshintsha ubushushu, kunye nemibhobho esetyenziswa kwiindawo zokucokisa i-petroleum. Ngokuqhelekileyo isetyenziselwa i-carbon steel high-quality (10, 20), i-alloy steel (12CrMo, 15CrMo), i-heat-resistant steel (12Cr2Mo, 15Cr5Mo), insimbi engenasici (1Cr18Ni9, 1Cr18Ni9Ti) yokuvelisa. Ukongeza kwimichiza eqinisekisiweyo yokwakheka kweekhemikhali kunye neempawu ezahlukeneyo zomatshini wombhobho wensimbi, kuyafuneka kwakhona ukuba kuqinisekiswe uxinzelelo lwamanzi, ukubetha, ukuvutha, kunye nezinye iimvavanyo, kunye nomgangatho womphezulu kunye nokuhlolwa okungonakalisi. Umbhobho wensimbi uhanjiswa phantsi konyango lokufudumala.
Umbhobho wensimbi engenastainless: Imibhobho yentsimbi eshushu eqengqelekayo kunye nebandayo eqengqelekayo yeentsimbi ezahlukahlukeneyo zisetyenziswa ngokubanzi kwimibhobho yezixhobo zepetroleum kunye neekhemikhali kunye neenxalenye zesakhiwo sentsimbi ngeenjongo ezahlukeneyo. Ukongeza ekuqinisekiseni ukubunjwa kweekhemikhali kunye neempawu zemishini, zisetyenziswa njengemibhobho yentsimbi enokumelana noxinzelelo lwamanzi. Ukuqinisekisa ukuba iimvavanyo zoxinzelelo lwamanzi zifanelekile. Zonke iintlobo zeepayipi ezikhethekileyo zetsimbi ziya kuqinisekiswa ngokwemiqathango ebekiweyo.
