I-boiler ye-high-pressureizinsimbi zendololwaneakhiqizwa ngamapayipi okubhayela anomfutho ophezulu kanye namapuleti
Amapayipi ensimbi anomfutho ophezulu nangaphezulu. Lawa mapayipi obhayela asebenza ngaphansi kokushisa okuphezulu nokucindezela okukhulu. Ipayipi lizophinde lifakwe i-oxidized futhi ligqwale ngaphansi kwesenzo segesi yokushisa ephezulu yokushisa kanye nomhwamuko wamanzi, ngakho ipayipi lensimbi liyadingeka ukuze libe nokuqina okuphezulu, ukumelana ne-oxidation ephezulu, nokuzinza okuhle kwenhlangano.
Amapayipi ensimbi angenamthungo wokumba i-geological kanye nokulawula ukumba uwoyela; sebenzisa izinsimbi zokumba ukuze kuqhutshekwe nokuhlolwa kwesakhiwo samadwala angaphansi komhlaba, amanzi angaphansi komhlaba, uwoyela, igesi yemvelo, nezimbiwa phansi.
Amapayipi ensimbi angenamthungo okulawula ukumba kwe-geological kanye nokumba uwoyela ayimishini yokumba eyinhloko, ehlanganisa ikakhulukazi umnyombo wangaphandle, ishubhu elingaphakathi elingaphakathi, i-casing, ipayipi lokubhoboza, njll. Ngoba amapayipi okubhoboza adinga ukujula ekujuleni kwamakhilomitha ambalwa , izimo zokusebenza ziyinkimbinkimbi kakhulu. Ipayipi lokubhoboza lingaphansi kwengcindezi efana nokushuba, ukucindezelwa, ukugoba, ukugoqa, kanye nomthwalo ongalingani, futhi libhekene nokuguga kodaka namadwala. Ngakho-ke, izinto zamapayipi ziyadingeka Kumele kube namandla anele, ubulukhuni, ukumelana nokugqoka, kanye nokuqina komthelela. Insimbi esetshenziselwa amapayipi ensimbi iboniswa nge-“DZ” (isiqalo se-Geological Chinese Pinyin) kanye nenombolo eyodwa ukumela iphoyinti lokukhiqiza lensimbi. Amapayipi ensimbi ahanjiswa esimweni esiphethwe ukushisa.
Amapayipi aqhekeka uwoyela: amapayipi angenamthungo amapayipi esithandweni, amapayipi okushintshanisa ukushisa, namapayipi asetshenziswa ezindaweni zokuhluza uphethiloli. Insimbi esetshenziswa kakhulu yekhwalithi ephezulu yekhabhoni (10, 20), i-alloy steel (12CrMo, 15CrMo), insimbi engashisi (12Cr2Mo, 15Cr5Mo), ukukhiqiza insimbi engagqwali (1Cr18Ni9, 1Cr18Ni9Ti). Ngaphezu kokwakhiwa kwamakhemikhali okuqinisekisiwe kanye nezakhiwo ezihlukahlukene zemishini yepayipi yensimbi, kuyadingeka futhi ukuqinisekisa ukucindezela kwamanzi, ukucaba, ukuvutha, nezinye izivivinyo, kanye nekhwalithi yendawo kanye nokuhlolwa okungabhubhisi. Ipayipi yensimbi ihanjiswa ngaphansi kokwelashwa kokushisa.
Ipayipi lensimbi engagqwali: Amapayipi ensimbi engagqwali agingqiwe ashisayo nabandayo ezinsimbi ezihlukahlukene ezingenasici asetshenziswa kakhulu kumapayipi emishini kaphethiloli namakhemikhali kanye nezingxenye zesakhiwo sensimbi engagqwali ngezinjongo ezihlukahlukene. Ngaphezu kokuqinisekisa ukwakheka kwamakhemikhali kanye nezakhiwo zemishini, asetshenziswa njengamapayipi ensimbi angakwazi ukumelana nokucindezela kwamanzi. Ukuqinisekisa ukuthi izivivinyo zomfutho wamanzi zifanelekile. Zonke izinhlobo zamapayipi ensimbi akhethekile zizoqinisekiswa ngokwemibandela ebekiwe.
