    I-Spiral Submerged Arc Welding in Oil Pipe Line Ulwakhiwo: Ukuqinisekisa uBomi beNkonzo kunye nokuthembeka koMfanekiso
    • I-Spiral Submerged Arc Welding in Oil Pipe Line Ulwakhiwo: Ukuqinisekisa uBomi beNkonzo kunye nokuthembeka

    Inkcazelo emfutshane:

    Ukwakhiwa kweimigca yombhobho yeoli yinkqubo ebalulekileyo nentsonkothileyo efuna eyona migangatho iphezulu yobugcisa bokuwelda.Phakathi kweendlela ezahlukeneyo ze-welding ezisetyenzisiweyo, i-spiral submerged arc welding (HSAW) ivelele njengokhetho lokuqala ngenxa yokusebenza kwayo okuphezulu kunye nempumelelo ekuqinisekiseni ubomi benkonzo kunye nokuthembeka kwemibhobho yeoli.Kule bhlog, siza kuphonononga ukubaluleka kwe-HSAW kwimibhobho ye-oyile yokuwelda kwaye sijonge iingenelo zayo kunye nexabiso elikhulu ekudibaneni nehlabathi.'s ukukhula iimfuno zothutho lweoyile.

    Ukubaluleka kwe-HSAW kulwakhiwo lwemibhobho yeoli:

    1. Amandla kunye noKuhlala ixesha elide: Enye yeempawu eziphambili ze-HSAW kukukwazi ukwenza i-welded welded joints.I-spiral weld eqhubekayo eyenziwa yile teknoloji yongeza imfezeko yolwakhiwo kwaye ibalulekile ukumelana noxinzelelo oluphezulu, amaqondo obushushu agqithisileyo kunye nezinto ezisingqongileyoumbhobho weoyile imigcaubuso ngexesha lobomi babo benkonzo.

    2. Ubomi obude kunye nokuthembeka okuqinileyo: Imigca yepayipi yeoli kulindeleke ukuba isebenze ngokufanelekileyo amashumi eminyaka, ukuthutha ioli ngaphandle kokuvuza okanye ukungaphumeleli.I-HSAW idlala indima ebalulekileyo ekufezekiseni ubomi benkonzo ende ngokuqinisekisa ngokusasazwa kobushushu be-welding, ukunciphisa uxinzelelo loxinzelelo, kunye nokuthintela ukuqaliswa kokuqhekeka kunye nokusabalalisa - zonke izinto ezinegalelo ekuthembekeni okupheleleyo kombhobho.

    3. Ulwakhiwo olusebenzayo: I-HSAW iyakwazi ukuwelda ngokuqhubekayo amacandelo amade ombhobho, ngoko inokusebenza okubonakalayo kulwakhiwo lwemibhobho.Le ndlela inciphisa ixesha le-welding, yandisa imveliso, inciphisa kakhulu iindleko zokwakha, kwaye ilungele ukugqitywa kweprojekthi ngexesha elifanelekileyo.

    4. Ukunciphisa ukugcinwa kunye nokulungiswa: Ngokubonelela ngekhwalithi ephezulu, i-welds-free-welds, i-HSAW inciphisa imfuno yokulungiswa kwexesha elizayo okanye ixesha lokuphumla elinxulumene nokugcinwa.Imibhobho yeoli eyakhiwe kusetyenziswa le ndlela ayinakukwazi ukuvuza okanye ukungaphumeleli, ukuphucula ukhuseleko kunye nokwandisa ukusebenza kakuhle.

    5. Izibonelelo zokusingqongileyo: I-HSAW iqinisekisa ukuveliswa kwee-welds ezichanekileyo kunye nokuchaneka okuphezulu kwe-dimensional.Oku kunciphisa ukubakho kokonakala kwemibhobho kunye nokuvuza kwe-oyile okulandelayo, ukukhusela okusingqongileyo kwiintlekele ezinokubakho ezinxulumene nokusilela kwemibhobho.

    a.Indlela ye-deoxidation yonyulwa ngolu hlobo lulandelayo:

    FF: Intsimbi ebulewe ngokupheleleyo equlethe izinto ezibophelelayo zenitrogen ngokwezixa ezaneleyo zokubopha initrogen ekhoyo (umz. min. 0,020 % iyonke iAl okanye i-0,015 % enyibilikayo iAl).

    b.Ixabiso eliphezulu le-nitrogen alisebenzi ukuba ukubunjwa kweekhemikhali kubonisa ubuncinane be-Al umxholo we-0,020 % kunye nomlinganiselo we-Al/N ubuncinane we-2: 1, okanye ukuba kukho ezinye izinto ezaneleyo ze-N-binding.Izinto ezibophelelayo ze-N ziya kubhalwa kuXwebhu loHlolo.

    Ukuququmbela:

    Ukwakhiwa kwemibhobho yeoli kufuna eyona migangatho iphezulu ye-welding ukuqinisekisa ubomi obude, ukuthembeka kunye nokhuseleko.I-Spiral submerged arc welding (HSAW) bubuchwephesha obungqiniweyo obukhethwayo kulo mmandla ngenxa yokukwazi ukwenza iiwelds ezinamandla, ezihlala ixesha elide kunye nezingenasiphako.Ngeengenelo ezininzi ezibandakanya imfezeko yolwakhiwo oluphuculweyo, ulwakhiwo olusebenzayo, ukugcinwa okuncitshisiweyo kunye neenzuzo zokusingqongileyo, i-HSAW idlala indima ephambili ekuhlangabezaneni neemfuno zothutho lweoyile kwihlabathi.Njengoko ishishini le-oyile liqhubeka nokwanda, ukusetyenziswa kobuchwephesha bokuwelda obuphambili obunje nge-HSAW kubalulekile ekugcineni ukuthembeka kunye nokuthembeka kwemibhobho yeoli kwihlabathi liphela.
