Ubuchwepheshe bokwandisa ukushisa busetshenziswe kabanzi ku-petroleum,imboni yamakhemikhali, amandla kagesi nezinye izimboni eminyakeni yamuva, insimu yesicelo ebaluleke kakhulu amapayipi emithombo kawoyela. Amapayipi ensimbi angenamthungo acutshungulwa ubuchwepheshe bokunwebeka okushisayo anezinzuzo zokuzinza kwe-dimensional, indawo ebushelelezi, futhi awekho amaphutha angaphakathi. Ngaphezu kwalokho, ukunwetshwa okushisayo kusetshenziswa futhi ekwandiseni ububanzi bangaphakathi, ukuncishiswa kwegobolondo, ukucubungula ekhoneni, njll. kwamapayipi ensimbi angenamthungo, okuthuthukisa ukusebenza kahle kokukhiqiza kanye nokunemba kokucubungula.

Ipayipi lensimbi elinwetshiwe elinwetshiwe liwuhlobo lwepayipi lensimbi elingenamthungo elakhiwe ngokushisa kanye nenqubo yokwandisa ububanzi. Uma kuqhathaniswa namapayipi ensimbi adonsayo adonsayo adonsayo, amapayipi ensimbi anwetshiwe ngokufudumeza anogqinsi oluncane lwezindonga kanye nobubanzi obungaphandle obukhulu. Inqubo yokukhiqiza yamapayipi ensimbi angenamthungo anwetshwe ngokufudumeza kuhlanganisa ukubhobozwa kwamaphasi amaningi, ukufudumeza, ukunwetshwa kobubanzi, ukupholisa nezinye izinyathelo. Le nqubo yokukhiqiza ingaqinisekisa ukuthi izindawo zangaphakathi nangaphandle zepayipi zibushelelezi futhi zinezakhiwo ezinhle zemishini.
Ukunwetshwa okushisayo kwamapayipi ensimbi kuyinqubo yokukhiqiza ipayipi yensimbi evame ukusetshenziswa. Inqubo yayo yokukhiqiza ingahlukaniswa ngezinyathelo ezilandelayo: ukulungiswa kwezinto ezibonakalayo, ukushisa kuqala, ukunwetshwa kokushisa nokupholisa.
Okokuqala, lungiselela izinto zokwakha. Izinto ezisetshenziswayo ezisetshenziswa kakhulu zingamapayipi ensimbi angenamthungo futhi ashiselwe avame ukusetshenziswa embonini kawoyela negesi. Lawa mapayipi ensimbi adinga ukuhlolwa kwekhwalithi ngaphambi kokukhiqizwa ukuze kuqinisekiswe ikhwalithi efanelekayo. Ipayipi lensimbi libe selisikwa futhi liyasikwa ukuze kuqinisekiswe ukuthi liwusayizi nobude obufanele.
Okulandelayo yisigaba sokufudumala. Faka ipayipi lensimbi esithandweni sokushisa bese usishisa ekushiseni okufanelekile. Inhloso yokushisa kuqala ukunciphisa ukucindezeleka nokuguqulwa ngesikhathi sokunwetshwa kokushisa okulandelayo nokuqinisekisa ikhwalithi jikelele nokusebenza kwepayipi yensimbi.
Bese ufaka isigaba sokunweba okushisayo. Ipayipi lensimbi elandulelwe ngaphambili lidliswa ku-expander yepayipi, futhi ipayipi yensimbi yandiswa ngomsakazo ngamandla we-expander yepayipi. Izandisi zamapayipi ngokuvamile zisebenzisa amarola anama-tapered amabili, eyodwa emile futhi enye ejikelezayo. Amarola azungezayo aphushela impahla odongeni lwangaphakathi lwepayipi lensimbi ngaphandle, ngaleyo ndlela andise ipayipi lensimbi.
Phakathi nenqubo yokwandisa ukushisa, ipayipi yensimbi ithinteka ngamandla kanye nokungqubuzana kwama-rollers, futhi izinga lokushisa lizokwanda. Lokhu akukwazi nje ukufeza ukwandiswa kwepayipi yensimbi, kodwa futhi kuthuthukise isakhiwo sangaphakathi sepayipi yensimbi futhi kuthuthukise izakhiwo zayo zemishini. Ngesikhathi esifanayo, ngenxa yamandla asetshenziswe kwipayipi yensimbi phakathi nenqubo yokwandisa ukushisa, ingxenye yokucindezeleka kwangaphakathi nayo ingaqedwa futhi ukuguqulwa kwepayipi yensimbi kungancishiswa.
Ekugcineni, kunesiteji sokupholisa. Ngemva kokuqedwa kokunwetshwa okushisayo, ipayipi lensimbi lidinga ukupholiswa ukuze libuyele ekamelweni lokushisa. Ngokuvamile, ipayipi lensimbi lingapholiswa kusetshenziswa isipholile, noma ipayipi lensimbi lingavunyelwa ukuba liphole ngokwemvelo. Inhloso yokupholisa iwukuqhubeka nokuzinzisa ukwakheka kwepayipi lensimbi nokuvimbela umonakalo odalwe ukuncishiswa kokushisa okushesha kakhulu.
Ukufingqa, inqubo yokukhiqiza yamapayipi ensimbi anwetshwe ngokushisa ihlanganisa izinyathelo ezine eziyinhloko: ukulungiswa kwezinto ezibonakalayo, ukushisa kwangaphambili, ukunwetshwa kokushisa nokupholisa. Ngale nqubo, amapayipi ensimbi anwetshwe ngokufudumeza anekhwalithi ephezulu nokusebenza okuhle kakhulu angakhiqizwa.
Njengobuchwepheshe obusebenzayo futhi obusezingeni eliphakeme bokucubungula amapayipi, inqubo yokwandisa okushisayo yamapayipi ensimbi engenamthungo isetshenziswe kabanzi ku-petroleum, imboni yamakhemikhali, amandla kagesi nezinye izimboni. Ekusetshenzisweni okusebenzayo, kuyadingeka ukunaka izindaba ezifana nekhwalithi yepayipi yensimbi, izinga lokushisa lokucubungula nesikhathi, ukuvikelwa kwesikhunta, njll, ukuqinisekisa imiphumela yokucubungula kanye nekhwalithi yomkhiqizo.
Izinto ezivamile zokunweba ezishisayo zifaka:Q345, 10, 20, 35, 45, 16Mn, i-alloy structural steel, njll.
