6. Inkqubo yoMveliso - Umbhobho weNsimbi weSSAW (Spiral Submerged Arc Welded)
Inkqubo yokwenziwa kweSSAW yePipe yeNsimbi (219mm – 3,500mm OD):
Ukuhlolwa kwezinto eziluhlaza (iKhoyili):Iikhoyili zentsimbi ezingenayo ezigoqwe ngobushushu ziqinisekisiwe ukuba zenziwe ngamakhemikhali, iimpawu zoomatshini, kunye nomgangatho womphezulu ngokuchasene neenkcukacha ze-API 5L X52. Ikhoyili nganye inikwe inombolo yobushushu eyahlukileyo ukuqinisekisa ukulandeleka ngokupheleleyo kwezinto kuyo yonke imveliso.
Ukuvula kunye nokulinganisa:Iikhoyili zentsimbi zifakwa kwi-uncoiler kwaye zifakwe ngomatshini wokulinganisa ngokuchanekileyo ukuze zithe tyaba umcu, zisuse iseti yeekhoyili kwaye ziqinisekise ukuba zithe tyaba ngokulinganayo ukuze kubekho ukwakheka okujikelezayo okuhlala kusenzeka.
Ukusila kunye nokuSika imiphetho:Zombini imiphetho emide yomcu wentsimbi iyasilwa kwaye inqunyulwe ukuze ifikelele kububanzi obuchanekileyo (± 0.5mm). Ukulungiswa komphetho kudala umphezulu ococekileyo, ohambelanayo obalulekileyo ekwakhiweni kwe-spiral weld esemgangathweni ophezulu.
Ukwakheka kweSpiral:Umcu olinganisiweyo ufakwa kumatshini owenza i-spiral kwi-engile ye-helix elawulwayo. Umcu uhlala usenziwa ube yi-spiral cylindrical shape, kunye nemiphetho elungelelaniswe ukuwelda. I-engile ye-helix inokulungiswa ukuze kufumaneke ububanzi obahlukeneyo be-coil efanayo.
Ukuwelda kwe-Arc efakwe ngaphakathi emanzini (i-SAW):Umthungo wangaphakathi ojikelezayo udityaniswa kuqala kusetyenziswa izixhobo zokuwelda ezifakwe kwi-arc ezizenzekelayo kunye nomxube ofanelekileyo we-flux kunye nocingo. Intloko yokuwelda ibekwe ngaphakathi kombhobho ukuqinisekisa ukungena ngokufanelekileyo.
Ukuwelda kwe-Arc engaphantsi kwamanzi (i-SAW) yangaphandle:Umthungo wangaphandle ojikelezayo udityaniswa kwangoko emva kwe-inner weld, kusetyenziswa izixhobo zokuwelda eziphantsi komhlaba ezizenzekelayo. I-interior weld igqibezela i-inpetting weld epheleleyo kwaye inika amandla ongezelelweyo.
Ukusika Ubude:Umbhobho odibeneyo ojikelezayo oqhubekayo unqunyulwa ngobude obuchaziweyo kusetyenziswa iinkqubo zokusika i-plasma okanye i-oxygen ezizenzekelayo ngolawulo lobude obuchanekileyo (+50mm -0mm kwiinkcukacha zemibhobho).
Uvavanyo Olungonakalisiyo (NDT):
Uvavanyo lwe-Ultrasonic oluyi-100% (UT):Inkqubo ye-UT ezenzekelayo ihlola yonke i-spiral weld seam kunye nomzimba wephayiphi epheleleyo ukuze ibone ukuba kukho ii-laminations, izinto ezifakiweyo, ukungabikho kwe-fusion, kunye nezinye izinto ezingahambelaniyo.
Uvavanyo lweRadiographic (RT):Ukuhlolwa kwe-X-ray okanye i-gamma-ray yomthungo we-weld (indawo okanye ubude obupheleleyo njengoko kuchaziwe) ukuqinisekisa umgangatho we-weld kunye nokungena kwayo.
Uhlolo lweeNgcawu zeMagnetic (MPI):Ukuhlolwa kweenzwane ze-weld kunye nendawo echaphazeleka bubushushu ukuze kujongwe imifantu yomphezulu kunye nokungaqhubeki kwawo.
Uvavanyo lwe-Hydrostatic:Kufuneka ukuze kuthotyelwe i-API 5L. Umbhobho ngamnye uvavanywa ngamanzi ukuya kuxinzelelo oluchaziweyo (ngesiqhelo yi-85-100% yamandla amancinci achaziweyo).
Ukugqiba Ukugqiba:Iziphelo ezingenanto (ezisikwele) okanye iziphelo ezibekiweyo (i-angle ye-bevel engama-30°-35°) ngokweemfuno zomthengi.
Uhlolo lokugqibela kunye nokumakishwa:Ukuhlolwa okubonakalayo kweziphene zomphezulu, ukuqinisekiswa kobukhulu (OD, WT, ubude, ukuthe tye, ukujikeleza), kunye nophawu olusisigxina ngokwe-API 5L (kubandakanya ibakala, ubungakanani, inombolo yobushushu, ukuchongwa komenzi, uphawu lwe-PSL).

9. Ukupakishwa kunye nokuthunyelwa - Ipayipi yentsimbi ye-API 5L X52 SSAW
Iipayipi zentsimbi ze-API 5L X52 SSAW ziyapakishwa kwaye zithunyelwa ngononophelo olukhulu ukuqinisekisa ukhuseleko lwazo ngexesha lokuhamba. Nantsi inkcazo yenkqubo yokupakisha kunye nokuthunyelwa kweepayipi ze-SSAW ezinkulu:
Ukupakisha:
Ukwaleka okuKhuselekileyo:Ngaphambi kokupakisha, imibhobho inokugqunywa ngomaleko omncinci weoyile yokulwa nomhlwa okanye ivanishi yokukhusela ukuthintela ukugqwala komphezulu kunye ne-oxidation ngexesha lokugcina kunye nokuthuthwa. Isiphelo esingenanto sikwafumaneka ukuze sisetyenziswe ngoko nangoko kwindawo oya kuyo.
Ukubopha (Ububanzi obuncinci):Kwimibhobho emincinci enobubanzi (ngesiqhelo ingaphantsi kwe-610mm / 24"), imibhobho ihlanganiswa ndawonye ibe ziibhanti eziziihexagonal okanye eziziingxande. Ziqiniswe kusetyenziswa iibhanti zentsimbi (ngesiqhelo iibhanti ezi-3-5 ngebhanti nganye enezikhuselo zeekona).
Ukunqwabelana Ngamnye (Ububanzi Obukhulu):Kwimibhobho emikhulu enobubanzi (ngaphezulu kwe-610mm / 24"), imibhobho idla ngokuphathwa kwaye ithunyelwe nganye nganye. I-dunnage yomthi okanye i-rubber padding ebekwe phakathi kweengqimba zemibhobho ithintela ukurhawuzelelwa kunye nokonakala kwengubo.
Iintloko zokuphela:Izigqubuthelo zeplastiki okanye zentsimbi zibekwe kuzo zombini iziphelo zombhobho ngamnye ukukhusela iziphelo ezibhityileyo, iziphelo ezingenanto kumonakalo obangelwa kukungqubana, ukungena kwenkunkuma, kunye nokufuma.
Ukugquma kunye nokugquma:Kwiiodolo zokuthumela ngaphandle ezikumgangatho ophezulu, izinto zokugquma ezifana neeringi zefoam, imicu yerabha, okanye i-dunnage yomthi zisetyenziswa phakathi kweengqimba zemibhobho ukuthintela ukurhawuzelelwa kunye nokonakala kwengubo.
Ukuhambisa ngenqanawe:
Indlela Yothutho:Iipayipi zithunyelwa ngeenqanawa zesikhongozeli (izikhongozeli ezingama-20ft okanye ezingama-40ft kwiidayamitha ezincinci), iithwali ezinkulu (ziqhekeza inqwaba kwiidayamitha ezinkulu kunye nomthamo omkhulu), okanye imithwalo kaloliwe.
Ukufakwa kwiikhonteyina (Ububanzi obuncinci):Kwimibhobho emincinci enobubanzi (ngesiqhelo ingaphantsi kwe-508mm / 20"), imibhobho ifakwa kwiikhonteyina zokuhambisa ezisemgangathweni ezingama-20ft okanye ezingama-40ft.
Ukulayisha iinqanawa ezinkulu (Ububanzi obukhulu kunye nomthamo omkhulu):Kwiiodolo ezinkulu (ngesiqhelo ezingaphezulu kweetoni ezingama-500) okanye iipayipi ezinkulu ezinobubanzi obungaphezulu kwe-508mm / 20"), iipayipi zilayishwa ngqo kwiinqanawa zokuthwala izinto ezinkulu okanye kwiinqanawa ezifakelwe iigiya.
Izikhongozeli zeRakhi eSicaba okanye eziVulekileyo eziphezulu:Kwimibhobho edlula ubungakanani obuqhelekileyo besikhongozeli (ubude >12m okanye ububanzi >2.3m), izikhongozeli zerack ezisicaba okanye izikhongozeli eziphezulu ezivulekileyo zingasetyenziswa.
Ukubhala iilebheli kunye noxwebhu:Iphakheji nganye okanye umbhobho ngamnye ubhalwe ngokucacileyo ngolwazi olubalulekileyo oluquka umgangatho wezinto, umgangatho, ubukhulu, inombolo yobushushu, inombolo yephakheji/umbhobho, kunye nemiyalelo yokuphatha.
Ukuthobela iMithetho yezeMali:Zonke iimpepha zerhafu ezifunekayo—i-invoyisi yorhwebo, uluhlu lokupakisha, i-invoyisi yemithwalo, iSatifikethi seMvelaphi, iiSatifikethi zoVavanyo lweMill—ziyalungiswa.
Ukubopha Okukhuselekileyo:Iibhanti kunye neepayipi ezahlukeneyo zibotshelelwa ngokukhuselekileyo kusetyenziswa imitya yentsimbi, iingxowa ze-dunnage, izixhobo zokubopha iinkuni, okanye ukubethelwa ngetyathanga.
Ukulandelela kunye nokuBeka esweni:Iinkqubo zokulandelela izinto eziphambili zibonelela ngohlaziyo lwendawo ngexesha langempela.
I-inshurensi:I-inshurensi yempahla yolwandle (Yonke Ingozi okanye Ngomgqumo oPhakathi) ingalungiselelwa.
Ngamafutshane, iWomic Steel iqinisekisa ukuba zonke iipayipi zentsimbi ze-API 5L X52 SSAW zipakishwe ngamanyathelo okukhusela aphambili kushishino kwaye zithunyelwa kusetyenziswa iindlela zothutho ezithembekileyo.
