Yiziphi Izinqubo Zokukhiqiza Zepayipi Lensimbi Elikhulu Lobubanzi?
Izinqubo zokukhiqiza eziyinhloko zamapayipi ensimbi anobubanzi obukhulu yi-LSAW, SSAW, kanye ne-Hot-finished Seamless.
I-LSAW (Longitudinal Submerged Arc Welding)
I-LSAW iyinqubo evame ukusetshenziswa ukwenza ipayipi elikhulu lensimbi eliwububanzi ngokushisela.
Isetshenziselwa ukwenza amapayipi ngokushisela i-arc engaphansi emanzini nhlangothi zombili.Okokuqala, izingcwecwe zensimbi zigotshwa zibe yisimo seshubhu, bese zishiselwa ndawonye ngokushisela i-arc engaphansi, bese ekugcineni zilolongwa futhi ziqondiswe ukuze kutholwe ububanzi nobude obufunekayo.
I-LSAW manje isingakwazi ukukhiqiza amapayipi afinyelela ku-1500mm ububanzi kanye no-80mm odongeni obukhulu.
I-SSAW (Spiral Submerged Arc Welding)
I-SSAW enye inqubo evame ukusebenzisa ukushisela ukwenza ipayipi lensimbi elinobubanzi obukhulu.
Ikhiqiza amapayipi ngokuzungezisa ikhoyili yensimbi ibe yisimo seshubhu kanye ne-arc welding engaphansi kwamanzi.
I-SSAW manje isingakwazi ukukhiqiza amapayipi afinyelela kububanzi obungu-3,500mm kanye nobukhulu bodonga obungu-25mm.
I-SMLS eqedwe okushisayo (Ingenamthungo)
Kuyinqubo yokukhiqiza ipayipi lensimbi engenamthungo, kunezinhlobo ezimbili zenqubo yokukhiqiza ipayipi yensimbi engenamthungo, ukushisa okuphelile futhi okubandayo kuqediwe, ukuqedwa okushisayo kulungele ukukhiqizwa kwepayipi elikhulu lensimbi.
Yakhiwe ngokushisa nokwelula ipayipi kusuka ku-billet eyindilinga eqinile, igcina ukufana namandla epayipi.
Ipayipi elingenamthungo eliqedwe ukushisa selingakwazi ukukhiqiza ipayipi lensimbi elinobubanzi obungu-660mm nogqinsi luka-100mm.
Kukhona enye inqubo yokushisela, i-EFW, nayo elungele ukwakhiwa kwamapayipi ensimbi anezindonga eziwugqinsi angaphezu kuka-406.4mm, kodwa ayisetshenziswa kabanzi njengalawa amathathu adlule.
Ukuqhathaniswa Kwezinqubo Zokukhiqiza Zemibhobho Yensimbi Enkulu Enkulu
Ipayipi yensimbi ye-LSAWingakhiqizwa ngokuqina kodonga okujiyile ngenxa yezimpawu zenqubo yayo yokukhiqiza ngakho-ke ingamelana nezingcindezi eziphakeme kunepayipi lensimbi le-SSAW ngokwezinga elithile.Kodwa-ke, ezindaweni ezinomfutho ophezulu, iziteshi ze-weld zingaba indawo ebuthakathaka yepayipi yensimbi ye-LSAW, engase ithinte amandla ayo okuthwala ingcindezi kanye nempilo yesevisi.
Ngaphezu kwalokho, imishini yokukhiqiza ye-LSAW ibiza kakhulu futhi ukusebenza kahle kokukhiqiza kuphansi kakhulu.
Ngakho-ke, amapayipi ensimbi e-LSAW asetshenziswa kakhulu kumapayipi afanele ukuthutha uwoyela, igesi yemvelo, neminye imidiya, kanye nezinye izinkambu zobunjiniyela nezokwakha ezidinga amandla aphezulu nokumelana nokucindezela.
Amapayipi e-SSAWafanele amadiamitha amakhulu, ikakhulukazi amadayamitha angaphezu kuka-1500mm, kanye namapayipi ahamba amabanga amade.
Uma kuqhathaniswa ne-LSAW, i-SSAW ishibhile kodwa ayizilungele izindawo zokusebenza ezinengcindezi ephezulu.
Ngakho-ke, amapayipi ensimbi e-SSAW asetshenziswa kakhulu uketshezi olunomfutho ophansi kanye nezinhloso zesakhiwo, njengamapayipi amanzi nezisekelo zebhuloho.
Ipayipi lensimbi le-SMLSifaneleka izicelo lapho izinga eliphezulu namandla epayipi lidingeka, njengoba inqubo yayo yokukhiqiza engenamthungo iqinisekisa ikhwalithi namandla epayipi.
Nokho, intengo ye-SMLS ivamise ukuba phezulu.
Ngakho-ke, isetshenziswa kakhulu emikhakheni edinga izinga eliphezulu nokuphepha, njengamapayipi okuthutha uwoyela negesi, amapayipi amakhemikhali, njalonjalo.
Amazinga Okusebenzisa Inqubo Yokukhiqiza
Izindinganiso ezivamile zokukhiqiza amapayipi ensimbi yilezi:
I-LSAW ne-SSAW: API 5L, ASTM A252, BS EN10210, BS EN10219
I-Hot-finished Seamless: API 5L, ASTM A53, ASTM A106, ASTM A210, ASTM A252, BS EN10210, JIS G3454, JIS G3456, JIS G3441,ASTM A213, ASTM A519, ASTM A335, ASTM A333.
Ukwelashwa Okungaphezulu Kwamashubhu Ensimbi Eyi-Diameter Enkulu
Ukwelashwa okungaphezulu kwepayipi elikhulu lensimbi eliwububanzi kubalulekile ukuvikela umzimba wepayipi, ukwandisa isikhathi sokusebenza, nokunciphisa ukugqwala.
Ukwelashwa kwangaphandle kwangaphandle kuvame ukuthatha umdwebo, i-3PE, i-FBE, i-3PP, njll, okuvimbela ngokuphumelelayo ukugqwala kwepayipi lensimbi ngemvelo yangaphandle.
Ukwelashwa kwendawo yangaphakathi, okuhlanganisa ukupenda kanye ne-FBE, kunganciphisa ukugqwala kwepayipi lensimbi ngoketshezi, kunwebe impilo yesevisi, futhi kunciphise ukungqubuzana phakathi nokuthuthwa koketshezi.
Ukukhetha indlela efanelekile yokwelashwa kwendawo kungaqinisekisa ukuthi ipayipi lensimbi linokumelana nokugqwala okuhle futhi livumelana nezimo ezihlukahlukene zokusetshenziswa kanye nezidingo.
