    Imibhobho e-Spiral eDidiweyo yeMibhobho yerhasi ephantsi komhlaba EN10219

    Imibhobho e-Spiral eDidiweyo yeMibhobho yerhasi ephantsi komhlaba EN10219 Umfanekiso obonakalayo
    • Imibhobho e-Spiral eDidiweyo yeMibhobho yerhasi ephantsi komhlaba EN10219

    Inkcazelo emfutshane:

    Ukwazisa umgangatho wethu weprimiyamu wemibhobho ye-spiral welded, eyilelwe ukuhlangabezana neemfuno ezibango zofakelo lombhobho werhasi ophantsi komhlaba. Le mibhobho yenziwe ngononophelo ukuya kwimigangatho engqongqo ebekwe kwi-EN10219, iqinisekisa ezona mfuno ziphezulu zonikezelo lobugcisa kumacandelo angaphakathi adityanisiweyo adityanisiweyo adityanisiweyo kwiintsimbi ezingenalo ialloyi kunye neenkozo ezicolekileyo.


    Iinkcukacha zeMveliso

    Iithegi zeMveliso

    Yethuimibhobho edityanisiweyozisisombululo esifanelekileyo kwiiprojekthi apho ukuxhathisa umhlwa kunye nemfezeko yesakhiwo kubalulekile. Inkqubo ye-welding ekhethekileyo ye-spiral ayigcini nje ukwandisa amandla ombhobho, kodwa inika indawo engenamthungo, ukunciphisa umngcipheko wokuvuza kunye nokungaphumeleli. Oku kubenza ukuba bafaneleke ngokukodwa kwiimeko ezingqongileyo ezihlala zidibana kwizicelo eziphantsi komhlaba.

    Umgangatho we-EN10219 uqinisekisa ukuba imibhobho yethu yenziwe ngokuchanekileyo kunye nomgangatho, ukuqinisekisa ukuba inokumelana noxinzelelo kunye nemingeni yokuthutha igesi yendalo. Igxininise ekomeleleni nasekuthembekeni, imibhobho yethu ye-spiral welded yenzelwe ukubonelela ukusebenza okuhlala ixesha elide, ukunciphisa imfuno yokugcinwa rhoqo kunye nokutshintshwa.

    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.

    Ukongeza kulwakhiwo lwazo olumagingxigingxi, le mibhobho ilula kwaye kulula ukuyiphatha, nto leyo eyenza ukuba ufakelo lusebenze kakuhle kwaye lungabizi kakhulu. Nokuba wenza iprojekthi entsha yokufaka imibhobho okanye uphucula inkqubo esele ikho, imibhobho yethu edityanisiweyo edityanisiweyo ibonelela ngendibaniselwano egqibeleleyo yamandla, ukuguquguquka, kunye nokuthobela imigangatho yoshishino.

    Khetha imibhobho yethu ejikelezileyo edityanisiweyo kwiimfuno zakho zombhobho werhasi ophantsi komhlaba kwaye ube namava oxolo lwengqondo oluza nokusebenzisa iimveliso ezidibanayo.EN10219imigangatho. Thembela ukuzinikela kwethu kumgangatho kunye nokusebenza ukuqinisekisa ukhuseleko kunye nokusebenza kakuhle kwezibonelelo zakho zegesi.
