Umehluko phakathi kwe-uoe neipayipi jco

Izinga elikhulu, ingcindezi ephezulu yokulethwa kwezidingo, amabanga amade ezokuthutha kanye nezinhlobo eziningi zezokuthutha kuwuphawu oluyinhloko lwenqubekelaphambili yezobuchwepheshe embonini yamapayipi, kodwa futhi inkambiso evamile yokuthuthukiswa kwemboni yamapayipi.Ngokuthuthuka kwemboni kawoyela yaseShayina, ulayini wegesi, umugqa wesibili, neminye imiklamo emikhulu eqhubekayo, ububanzi obukhulu, ukushuba kodonga lwepayipi elinomfutho ophezulu, kuthuthukisa kakhulu isidingo.Ipayipi elishiselwe i-spiral seam weld alikwazanga ukuhlangabezana nezidingo ngokomthamo nokusebenza kokuphepha, ububanzi obukhulu, ukushuba kodonga, amapayipi ezinga eliphezulu le-LSAW ozothatha indawo yepayipi elishiselwe elivunguzayo seliphenduke inkambiso engenakugwenywa.Ikhwalithi enokwethenjelwa yepayipi le-LSAW, isetshenziswe kabanzi emazweni angaphandle kuwoyela negesi yomugqa wetrunk wokudlulisa we-voltage ephezulu.Eminyakeni yakamuva, leli zwe lizokwakha kancane kancane amandla okukhiqiza amapayipi e-LSAW, ubuchwepheshe bepayipi elivamile le-UOE kanye ne-JCOE yobuchwepheshe.

Ngokuthuthukiswa kwezinga lensimbi, ukwakhiwa kwamapayipi, umthungo oqondile oshiselwe ipayipi le-arc elishiselwe ukuba libe ukukhetha kokuqala komugqa omkhulu we-trunk, ikakhulukazi endaweni yemvelo enokhahlo, ipayipi lasolwandle elinabantu abaningi.“I-West-East Gas Pipeline Project, yezinhlobo ezimbili, ezintathu, ezine zepayipi elikhulu elicijile le-arc elishiselwe, elingu-14% lenziwa ishubhu le-JCOE, kanti elinye lithunyelwa kwamanye amazwe ipayipi le-UOE.

Inqubo yokukhiqiza ye-UOE

Okubalulekile kusiguquli sepuleti lensimbi→ukucwenga→ukusakaza okuqhubekayo→i-slab→welding arc board→Ukugaya→ngaphambili→Uyabumba→O ukwakha amanzi anengcindezi ephezulu→omile→i-presoldering→ukushisela→ukususwa kwe-welding flange yangaphandle ekhonjiwe ibhodi le-arc→weld kanye nepayipi→ipayipi ekupheleni enwetshiwe ububanzi ekupheleni ukutholwa ultrasonic flaw→Ukuhlolwa kwe-X-ray→Ipayipi→i-tube end welds flathead epholishiwe→ukuhlolwa kwe-hydrostatic→Ipayipi le-weld ekupheleni Ukuhlolwa kwe-X-ray kokuhlolwa kwe-ultrasonic kwe-weld kanye nokuphela kwepayipi ukuphela kwe-stratification kanye nokuhlolwa kwezinhlayiya kazibuthe→i-remanence demagnetization→ukuhlolwa kwefekthri→ukukala→i-chamfer→ukulinganisa ubude bendandatho yeshubhu→uphawu lokufutha→ukuthutha okustakiwe

Inqubo yokukhiqiza ye-JCOE

Impahla kabusha-→i-vacuum ilenga→uphenyo lwebhodi→bhapha→i-curl yokuhlela ngaphambi kwepuleti le-demi (J ukubumba) livuliwe.unqenqema lwebhodi→khulula→faka ipuleti lensimbi ye-demi (C ukubumba) ipuleti lensimbi ye-demi→curl→khulula→goba→pre-welded→i-welding ibalule ibhodi le-arc (ecimayo).→ukushisela→Qing impande Weld→ukuphela kokulungiswa komshini ekuhlolweni okukhonjiwe kwe-hydrostatic (kukhishwe) ku-arc ibhodi→ukuhlolwa kwe-ultrasonic→ukunwetshwa komshini→I-tube ekupheleni kwendandatho yokuhlola ye-ultrasonic→Ukuhlolwa kwe-X-ray→Ukuhlolwa kwezinhlayiyana kazibuthe kokuhlolwa komkhiqizo oqediwe→ukukala nokulinganisa ubude bokuhlolwa kwe-UT stratification→ngaphandle kwe-anticorrosion→ukugqwala kwangaphakathi→umaka→ukulethwa

Ukukhiqizwa kwe-UOE ne-JCOE, ukuhlukaniswa kwemikhiqizo ehlukene

Umbono ovela ezinkambisweni ezimbili zokukhiqiza, kokubili ohlelweni lokwakha ingaphambili nangemuva ngokuyisisekelo kuyafana, umehluko omkhulu ukuthi indlela yokubumba.Ukwakheka kwe-UOE ikakhulukazi kuqukethe izinyathelo ezimbili: ukubumba u-U kanye no-O ukubumba.Futhi i-JCOE eyenza ingxenye yohlelo ihlukaniswe izingxenye eziyisithupha, ukusebenza kahle kokukhiqiza kuyancipha kakhulu.Ukwakha indlela ehlukile, okuholela kumehluko we-UOE ne-JCOE ngobubanzi, ukushuba kodonga, ubukhulu, ukusebenza kahle kokukhiqiza, isilinganiso sesivuno.

Ipayipi likalayini we-UOE kanye ne-JCOE yepayipi lamapayipi kusukela ekuhlaziyeni okuqhathanisayo kwenqubo yokukhiqiza nezindleko zokukhiqiza, iziphetho ezilandelayo:

(1) Ukusebenza kahle kokukhiqiza kwe-UOE, umthamo, kanye nokushintshwa kwesikhunta isikhathi eside, esilungele ukukhiqizwa

(1) Ukusebenza kahle kokukhiqiza kwe-UOE, amandla, kanye nokushintshwa kwesikhunta isikhathi eside, esifaneleka kangcono ukukhiqizwa kwenani elikhulu, umkhiqizo wencazelo eyodwa;ukukhiqiza i-JCOE engasebenzi kahle, isikhunta esihambisana nokucaciswa okuhlukahlukene, esilungele ukukhiqizwa kwevolumu encane, imikhiqizo enemininingwane eminingi.

(2) i-UOE ikhiqiza ububanzi bemikhiqizo nobubanzi obujiyile kufanele bube ngaphansi kwe-JCOE, kodwa bukwazi ngokugcwele ukuhlangabezana nezidingo zephrojekthi.

(3) Ngokombono wokusebenza, ipayipi lolayini le-UOE liqhathanise i-JCOE abanengcindezi eyinsalela, ukunemba okuphezulu Ubukhulu bunikeza izinzuzo kunezincane.
