    Funda malunga ne-A252 yeBanga lesi-2 lombhobho wentsimbi:

    A252 IBANGA 2 Umbhobho wentsimbingumbhobho wentsimbi yekhabhoni eyenzelwe ngokukodwa ukusetyenziswa kwimibhobho yoxinzelelo kunye nezicelo zesakhiwo.Yenziwe ngokuhambelana nemigangatho ye-ASTM (i-American Society for Testing and Materials), iqinisekisa imigangatho yomgangatho ophezulu kunye nokuchaneka kwe-dimensional.Ukutyunjwa kwe-GRADE 2 kubonisa ukuba umbhobho wensimbi wenziwa kusetyenziswa i-arc ye-arc efakwe emanzini okanye iindlela zokudibanisa ezingenamthungo.

    Ukubaluleka kokuwelda kwe-arc entywiliselwe kabini:

    Ukuwelda kwe-arc entywiliselwe kabini, eyaziwa ngokuba yi-DSAW, yinkqubo ye-welding ekhethekileyo esetyenziselwa ukujoyina amacandelo e-A252 GRADE 2 yepayipi yensimbi.I-DSAW ibonelela ngeengenelo ezininzi ngaphezulu kwezinye iindlela ze-welding, kubandakanya ingqibelelo ebalaseleyo ye-weld, isantya esiphezulu se-welding, ukugqwetheka okuncinci, kunye nolawulo olubalaseleyo lokufaka ubushushu.Iqinisekisa ibhondi eyomeleleyo phakathi kwemibhobho, ibenza bangabikho lula ukuvuza, ukubola kunye nomonakalo wesakhiwo.

    Kutheni kusetyenziswe umbhobho wentsimbi i-A252 yeBanga lesi-2 kwiiprojekthi zogutyulo?

    1. AMANDLA OKUGQIBELEYO NOBUDALA: I-A252 IBANGA 2 ipayipi yensimbi inamandla aphezulu, okwenza ukuba ikwazi ukumelana noxinzelelo kunye noxinzelelo lwangaphandle.Ukuqina kwabo kuqinisekisa ubomi obude benkonzo, ukunciphisa imfuno yokutshintshwa rhoqo okanye ukulungiswa.

    2. Ukumelana noKutya: I-A252 IBANGA 2 lombhobho wentsimbi yenzelwe ukumelana neemeko ezimandundu phantsi komhlaba, kubandakanywa nokuvezwa kugutyulo, iikhemikhali kunye nokufuma, ngaphandle kokubola okanye ukuthotywa.Olu phawu lunyusa kakhulu ubomi benkonzo yemibhobho yogutyulo.

    3. Ixabiso eliphantsi: i-A252 yeBanga lesi-2 lombhobho wentsimbi ibonelela ngesisombululo esingabizi kakhulu sokwakhiwa kwemibhobho yogutyulo.Iimfuno zabo eziphantsi zogcino kunye nobomi obude bunokusindisa oomasipala kunye neekontraka zeprojekthi ukonga okubalulekileyo ekuhambeni kwexesha.

    Iinkqubo zemibhobho yeWelding

    Ukusetyenziswa kombhobho wentsimbi we-A252 kwibakala lesi-2 kubunjineli bogutyulo:

    Umbhobho wentsimbi we-A252 IBANGA 2 usetyenziswa ngokubanzi kwiiprojekthi ezahlukeneyo zeziseko zogutyulo, kuquka:

    1. Inkqubo kamasipala yogutyulo lwelindle: Imibhobho yentsimbi engu-A252 yeBanga lesi-2 isetyenziswa ngokubanzi kulwakhiwo lwemibhobho yogutyulo lweziseko ezingundoqo zikamasipala ukuze kuthuthwe ngokufanelekileyo amanzi amdaka ukusuka kwiindawo zokuhlala kunye nezorhwebo ukuya kwiindawo zokucocwa.

    2. INkqubo yoGutyulo lwamanzi amdaka kwimizi-mveliso: Izakhiwo zemizi-mveliso zifuna iinkqubo zogutyulo ezomeleleyo ukuze zijongane nokulahlwa kwamanzi amdaka asuka kwiiyunithi zokwenziwa kwezixhobo nezinye izixhobo.I-A252 GRADE 2 yentsimbi yombhobho inika amandla ayimfuneko kunye nokuqina kolu hlobo lokusetyenziswa kombhobho wamanzi amdaka.

    Ukuququmbela:

    Xa kufikwa kuumgca wogutyuloukwakhiwa, i-A252 GRADE 2 ipayipi yentsimbi edityaniswe neteknoloji ye-welding ye-DSAW inika amandla angenakulinganiswa, ukuqina kunye nokusebenza ngokubanzi.Ukumelana nomhlwa okungaqhelekanga, ukomelela okugqwesileyo kokuqina kunye nokusebenza kakuhle kweendleko kuyenza ilungele iiprojekthi ezahlukeneyo zeziseko zogutyulo.Ngokwamkela ezi zixhobo zihambele phambili kunye neendlela zokuwelda, izixeko zinokubunyusa kakhulu ubomi kunye nokusebenza kakuhle kweenkqubo zazo zogutyulo, zinciphise iindleko zokugcinwa kwazo kwaye ziqinisekise indawo ecocekileyo, esempilweni kuye wonke umntu.
