Emkhakheni wobuchwepheshe bokubona,ipayipi elikhulu lensimbi elingenamthungoibhekisela kububanzi obungaphezu kuka-160 mm.Ipayipi lensimbi elingenamthungo elinobubanzi obukhulu liyimpahla ebalulekile ye-petroleum, amakhemikhali, eshisayo, ebhayela, imishini, nemboni ye-hydraulic, njll. Ngokuthuthuka komnotho wezwe, izwe lethu ngesikhathi "sohlelo lwe-11 lweminyaka emihlanu", landa kakhulu isidingo ipayipi lensimbi elingenamthungo, futhi liveza ukuthambekela kokuthuthukiswa kobubanzi obukhulu kakhulu.Ikakhulukazi ukumelana nokugqwala, ukumelana nokukhama ipayipi lomthombo kawoyela kanye neshubhu likabhayela elinomfutho omkhulu nobubanzi obuphezulu kanye nepayipi lekhwalithi ephezulu eliqhekeka uwoyela, ipayipi le-petroleum ne-petrochemical, njll., kuzoba njengoba amazwe ekhula njengesidingo sendawo eshisayo yokutshalwa kwengqalasizinda yamandla.Ngakho-ke, ukuqinisekisa ikhwalithi yemikhiqizo yokuhlola okungonakali kubeka phambili izindlela namasu esihlokweni esisha.

Njengamanje, imboni yensimbi yaseChina yokutholwa kwamapayipi ensimbi angenamthungo ocindezelwe kakhulu kusetshenziswa ikakhulukazi ku-phi 160 mm ngaphansi kwesicaciso, futhi yamukela ikhoyili yendabuko ye-eddy yamanje yokuthola iphutha noma indlela yokuhlola amanzi yohlobo oluzimele lwe-ultrasonic.Kumapayipi ensimbi angenamthungo angaphezu kuka-160 mm ngokusebenzisa indlela yamanje yohlobo lwe-eddy esetshenziselwa ukuhlola, kunezinkinga eziningi, futhi ezingavunyelwe ezingeni likazwelonke.Uma usebenzisa ukuhlolwa kwe-ultrasonic kokuzimela, ngenxa yendlela yokuthola i-ultrasonic yokuba khona kokujula okuthile endaweni eyimpumputhe, angeke kuqinisekiswe ukwethembeka kwemiphumela yokuhlola iyonke.

Ngekhoyili yokutholwa kwamanje kwe-eddy kuyindilinga ebusweni bendawo yepayipi lensimbi.Isetshenziswa ngekhoyili, ukutholwa kwephutha lamanje kwe-eddy yobubanzi beshubhu lensimbi elihloliwe, ukutholwa okukhulu kwekhoyili, kuba nkulu indawo ezungezile ye-SNR ephansi.Kungenxa yalesi sizathu, izinga lokuhlola lamanje lepayipi lensimbi, elisetshenziswa ngekhoyili, ukutholwa kwephutha lamanje lobukhulu bomnotho bamazwe angaphandle akufanele libe ngaphezu kuka-140 mm.Ngaphezu kwalokho, ku-diameter yensimbi ipayipi elikhulu ngokusebenzisa ukuhlolwa kohlobo, ishubhu yensimbi ye-magnetization kanye ne-demagnetization, kunobunzima obuthile.

Ukuhlolwa kwe-ultrasonic yohlobo lwethangi lamanzi ukusebenzisa ipayipi lensimbi elivunguzayo, i-ultrasonic probe elungisiwe.Ngosinki futhi wahlola izici zepayipi lensimbi eligcwele amanzi ngaphansi kokuhlangana, qinisekisa ukuthi ubukhulu bongqimba bokuhlanganisa buhlala bufana.Kodwa ukuze kutholwe amaphutha angaphakathi nge-ultrasonic ebusweni bezinkinga ezinkulu ezikhona endaweni eyimpumputhe nesikhathi, okuholela ekungakwazi ukukubona, okuhambisana nokuqhubekela phambili okuvunguzayo, ipayipi lensimbi elibude obungu-30 m kuya ku-12 m ubude lidinga indawo yokuhlala, njll. kube nomthelela ekukhetheni kwendlela yokuthola ipayipi lensimbi kanye nokuphromotha.

Ngakho-ke, ukuhlola ipayipi elikhulu lensimbi eliwububanzi ekhaya naphesheya, ngokuvamile kusetshenziswa indlela yokuvuza kazibuthe noma ukuhlolwa kwengcindezi yamanzi.Ekhaya, akuwona ukusebenza kahle kwepayipi elikhulu lensimbi elinobubanzi obukhiqizwe idivayisi yokubona ukuvuza kozibuthe, eyake yasetshenziswa ukungenisa.Ukungeniswa kwamanye amazwe kwedivayisi yokubona ukuvuza kukazibuthe kuyabiza, kunzima ukwamukela ezinkampanini eziningi zasekhaya;Futhi ukusebenza kahle okuphansi kokuhlolwa kokucindezelwa kwamanzi, ukuqina kwabasebenzi kukhulu, ikakhulukazi uma opharetha umuzwa wokuzibophezela ungekho phezulu, ukuhlolwa kokucindezela kwamanzi.Okubonakalayo, ukugcwaliseka kokuhlolwa kweshubhu lensimbi elingenamthungo elikhulu lobubanzi sekuphenduke isihloko esizoxazululwa ngokushesha embonini yepayipi lensimbi yensimbi.
