    Ukuqonda ukubaluleka kweNkqubo yokuWelding eyiPipe yeSpiral Steel Pipe esetyenziswa kwiMigca yamanzi aphantsi komhlaba.

    Ukuqonda Ukubaluleka kweNkqubo yeMibhobho eLungileyo yokuWelding kuMbhobho weSpiral Steel osetyenziswa kwiMigca yaManzi aphantsi komhlaba
    • Ukuqonda ukubaluleka kweNkqubo yokuWelding eyiPipe yeSpiral Steel Pipe esetyenziswa kwiMigca yamanzi aphantsi komhlaba.

    Inkcazelo emfutshane:

    Xa ufaka imigca yamanzi angaphantsi komhlaba, ukusebenzisa umbhobho ophezulu kubaluleke kakhulu ekuqinisekiseni ukuqina kwexesha elide kunye nokuchasana nezinto ezisingqongileyo.Olunye uhlobo lombhobho oluqhelekileyo olusetyenziselwa imigca yamanzi angaphantsi komhlaba ngumbhobho wentsimbi ejikelezayo.Nangona kunjalo, ukusebenzisa nje imibhobho ekumgangatho ophezulu akwanelanga ukuqinisekisa ubomi obude bemibhobho yakho yamanzi.Iinkqubo ezifanelekileyo zokudibanisa imibhobho zibalulekile ekuqinisekiseni ukuba imibhobho yentsimbi ejikelezayo inokumelana neemeko ezinzima phantsi komhlaba kwaye ibonelele ngonikezelo lwamanzi oluthembekileyo.


    Iinkcukacha zeMveliso

    Iithegi zeMveliso

     Imibhobho yentsimbi ye-Spiralzisetyenziswa kakhulu kwimibhobho yamanzi aphantsi komhlaba ngenxa yamandla ayo aphezulu kunye nokukwazi ukumelana noxinzelelo lwangaphandle.Le mibhobho yenziwa ngemicu yentsimbi esongwe eshushu eyenza imilo ejikelezayo.Inkqubo ye-spiral welding esetyenziselwa ukuvelisa le mibhobho ibonelela ngokugqibeleleyo kolwakhiwo imfezeko, iyenza ilungele ukusetyenziswa phantsi komhlaba.

    1.Kwakhona kukho imibhobho yentsimbi kwidayamitha yangaphandle yegama kunye nobukhulu bodonga oluphakathi phakathi kobukhulu bayo obusondeleyo obudweliswe kwitheyibhile, kodwa isivumelwano siya kusayinwa.

    2. Iidayamitha zangaphandle eziqingqiweyo kwizibiyeli kwitheyibhile zigcinwe iidiameters.

    Enye yezona zinto zibalulekileyo zokusebenzisa i-spiral steelumbhobho wemigca yamanzi angaphantsi komhlabaziinkqubo ezifanelekileyo ze-welding.I-Welding yinkqubo yokudibanisa iinxalenye ezimbini zetsimbi ngokufaka ukushisa kunye noxinzelelo.Kwimibhobho yamanzi angaphantsi komhlaba, umgangatho we-welding uchaphazela ngokuthe ngqo ukunyaniseka okupheleleyo kunye nokuthembeka kombhobho.

    Ngokufanelekileyoiinkqubo ukuwelda imibhobhokuba umbhobho wentsimbi ejikelezayo ubandakanya amanyathelo abalulekileyo.Okokuqala, umphezulu wombhobho odityanisiweyo kufuneka ucoceke kwaye ungabikho nakuphi na ukungcola okunjengokungcola, ioli, okanye ipeyinti.Oku kuqinisekisa ukuba i-weld yomelele kwaye ayinayo ukungcola okunokuthi ibeke esichengeni amandla ayo.

    Umbhobho we-SSAW

    Okulandelayo, iiparamitha ze-welding ezifana negalelo lobushushu, isantya se-welding, kunye nobuchule kufuneka ilawulwe ngononophelo ukufezekisa i-welds ekumgangatho ophezulu.Ukusebenzisa izinto ezifanelekileyo ze-welding kunye nobuchule kubalulekile ekuthinteleni iziphene ezifana ne-porosity, ii-cracks, okanye ukungabikho kokudibanisa, okunokuphazamisa ingqibelelo ye-weld.

    Ukongezelela, ukufudumeza okufanelekileyo kunye neenkqubo zokunyanga ukushisa emva kwe-weld zibalulekile kumbhobho wensimbi ojikelezayo osetyenziswa kwimigca yamanzi aphantsi komhlaba.Ukufudumala kunceda ukunciphisa umngcipheko wokuqhekeka kunye nokuphucula umgangatho we-weld jikelele, ngelixa unyango lwe-post-weld heat lukhulula uxinzelelo olushiyekileyo kwaye luqinisekisa i-microstructure efanayo kuyo yonke indawo ye-weld.

    Ukongeza, ukusetyenziswa kwetekhnoloji ye-welding ephezulu efana neenkqubo ze-welding ezizenzekelayo kunye novavanyo olungonakalisiyo kunokuphucula ngakumbi umgangatho kunye nokuthembeka kwe-welding.Ezi teknoloji zinceda ekuqinisekiseni ukuba i-welded joints ihlangabezana namandla ayimfuneko kunye nemigangatho yomgangatho wokubonelela ngoxolo lwengqondo malunga nokusebenza kwexesha elide lemigca yamanzi aphantsi komhlaba.

    Isishwankathelo, iinkqubo ezifanelekileyo zokudibanisa imibhobho zibalulekile ekuqinisekiseni ukunyaniseka kunye nokuphila ixesha elide lombhobho wensimbi ojikelezayo osetyenziswa kwimigca yamanzi aphantsi komhlaba.Ngokulandela iiparitha eziyimfuneko zokudibanisa, ubuchule kunye namanyathelo okulawula umgangatho, umngcipheko weziphene ze-welding kunye nokungaphumeleli kunokunciphisa kakhulu.Isiphumo singumzila wamanzi aphantsi komhlaba othembekileyo nozinzileyo onokumelana novavanyo lwexesha kunye nokubonelela ngeenkonzo zokuhanjiswa kwamanzi ezikhuselekileyo nezisebenzayo.Kwimizila yamanzi angaphantsi komhlaba, utyalo-mali kwiprogram ye-welding efanelekileyo linyathelo elibalulekileyo ekuqinisekiseni ukuthembeka okupheleleyo kunye nobude obude bombhobho.
