Ukwelashwa kwe-coating of pipeline Ukusebenzisa ukushisa kwe-induction kuhilela inqubo lapho ukushisa kukhiqizwa khona ngokuqondile odongeni lwamapayipi noma izinto zokumboza ngenkambu ye-electromagnetic. Le ndlela isetshenziselwa ukwelapha i-epoxy, i-powder coatings, noma ezinye izinhlobo zezingubo ezidinga ukushisa ukuze kumiswe futhi kuqine ngendlela efanele.
Nakhu okufingqiwe kokuthi inqubo ngokuvamile isebenza kanjani:
Ukulungiselela: Indawo yepayipi ilungiselelwe ukumbozwa. Lokhu kungase kuhlanganise ukuhlanza kanye nokusebenzisa i-primer noma i-undercoat kuye ngezidingo zesistimu yokumboza.
Isicelo sokuhlanganisa: I-coating isetshenziswa epayipini. Lokhu kungenziwa ngokufafaza, ukuxubha, noma enye indlela efanele izinto zokumboza kanye nepayipi.
Ukusethwa kwekhoyili yokungeniswa: Ngemuva kokufaka isicelo sokumboza, amakhoyili e-induction abekwa eduze kwepayipi. Lawa makhoyili ayingxenye ye- ukufakwa kokushisa uhlelo okufaka umthombo wamandla neyunithi yokulawula.
Inqubo yokushisisa: Isistimu yokushisa yokungeniswa iyasebenza. Umsinga oshintshanayo udlula ikhoyili yokungeniswa, udale inkambu kazibuthe ehlukahlukene eyenza ama-eddy currents kwinto yepayipi eliqhubayo.
Ukwelapha: Imisinga ye-eddy ikhiqiza ukushisa ngenxa yokumelana nogesi wezinto zamapayipi. Lokhu kushisa kudluliselwa ku-coating, kukhuphule izinga lokushisa elidingekayo lokwelapha. Izinga lokushisa nobude besikhathi sokushisa kuncike ohlotsheni lwe-coating esetshenzisiwe kanye nemininingwane yomkhiqizi.
Ukuqapha Nokulawula: Izinga lokushisa lepayipi nokumboza liqashwe ngokucophelela, ngokuvamile ngezinzwa zokushisa noma amakhamera e-infrared, ukuqinisekisa ngisho nokushisa nokuvimbela ukushisa ngokweqile, okungalimaza ukumboza noma ipayipi. Isistimu yokushisa yokungeniswa ilawulwa ukuze kugcinwe izinga lokushisa elidingekayo lokuphulukisa ngesikhathi esibekiwe.
Ukupholisa: Ngemuva kokuthi isikhathi sokuphulukisa sesiphelile, ukushisa kwe-induction kuvaliwe, futhi ipayipi ivunyelwe ukupholisa. Lokhu kungase kube inqubo elawulwayo ukuze kugwenywe ukushaqeka okushisayo noma imiphi imiphumela emibi ekuqineni kwentolo.
Ukuhlolwa: Uma ipayipi selipholile, ukunamathela kuyahlolwa ukuze kuqinisekiswe ukuthi selaphekile ngendlela efanele. Izindlela zokuhlola zingase zihlanganise ukuhlola okubukwayo, izilinganiso zokuqina kwefilimu eyomile, ukuhlola ukunamathela, nokutholwa kweholide ukuze kuqinisekiswe ukuthi akukho sici noma ukungaqhubeki ekunambeni.
Ukushisa kwe-induction yokwelapha okunamathela kumapayipi kunikeza izinzuzo eziningana:
Isivinini: Ukushisa kwe-induction kungaphulukisa ukunamathela ngokushesha kakhulu kunezindlela zendabuko ezifana nokwelapha kuhhavini noma ukomiswa komoya.
Ukulawula: Inqubo inikeza ukulawula okunembile phezu kwezinga lokushisa lokushisa kanye nesilinganiso, okuholela ekwelapheni okufanayo kwe-coating.
Ukusebenza Kahle Amandla: Ukushisa kokungeniswa kuvame ukonga amandla kunezinye izindlela zokushisisa ngoba ukushisa kukhiqizwa ngokuqondile endabeni.
Ukuphepha: Le ndlela inciphisa ingozi yomlilo nokuqhuma njengoba awekho amalangabi avulekile noma izindawo ezishisayo.
Ukushisa ukushisa luwusizo ikakhulukazi ekusetshenzisweni kokuhlanganisa okuhlangene kwendawo lapho izingxenye zamapayipi zishiselwe ndawonye ensimini futhi ukunamathela endaweni ehlangene kudinga ukwelashwa ngokushesha ukuze kugcinwe ubuqotho besistimu yokuvikela yepayipi.
