    Inkcazo emfutshane:

    Olu lwazi lugubungela izixhobo zentsimbi yekhabhoni eyosiweyo kunye nentsimbi ye-alloy ezakhiwe ngendlela engenamthungo neyomeleleyo. Ezi zixhobo zenzelwe ukusetyenziswa kwimibhobho yoxinzelelo nakwizinto zokwenziwa kwesitya soxinzelelo ukuze zisebenze kumaqondo obushushu aphakathi naphezulu. Izinto zokufakelwa kufuneka zibe yintsimbi ebuleweyo, izixhobo zokufakelwa, imivalo, iipleyiti, iimveliso zetyhubhu ezifakwe i-seamless okanye ezihlanganisiweyo ezinentsimbi yokuzalisa eyongeziweyo. Imisebenzi yokufakelwa okanye yokubumba inokwenziwa ngokubethela, ukucinezela, ukubhoboza, ukukhupha, ukujika, ukugoba, ukuwelda kwe-fusion, ukuchwetheza, okanye ngokudityaniswa kwezi zenzo zimbini okanye ezingaphezulu. Inkqubo yokwenza kufuneka isetyenziswe ngendlela yokuba ingavelisi iimpazamo ezonakalisayo kwizixhobo. Izixhobo, emva kokwenziwa kumaqondo obushushu aphezulu, kufuneka zipholiswe kumaqondo obushushu angaphantsi komgangatho obalulekileyo phantsi kweemeko ezifanelekileyo ukuthintela iziphene ezinobungozi ezibangelwa kukupholisa ngokukhawuleza kakhulu, kodwa akukho meko ikhawulezayo ngaphezu kwesantya sokupholisa emoyeni ozinzileyo. Izixhobo kufuneka zivavanywe ngoxinzelelo, uvavanyo lobunzima, kunye novavanyo lwe-hydrostatic.

    *2. Ngaphandle kokuba kuyimfuneko, ixabiso lobulukhuni akufuneki lixelwe.

    Ukuveliswa

    Izixhobo zombhobho wentsimbi yekhabhoni ze-ASTM A234 zinokwenziwa ngeepayipi ezingenamthungo, iipayipi ezidityanisiweyo okanye iipleyiti ngokubumba imisebenzi yokucinezela, ukubhoboza, ukukhupha, ukugoba, ukudityaniswa kwe-welding, ukukhanda, okanye ngokudityaniswa kwezi zenzo zimbini okanye ezingaphezulu. Zonke ii-welds kuquka ii-welds kwiimveliso zeetyhubhu apho kwenziwa khona ii-fittings kufuneka zenziwe ngokuhambelana neCandelo le-ASME IX. Unyango lobushushu emva kokudityaniswa kwi-1100 ukuya kwi-1250°F[595 ukuya kwi-675°C] kunye novavanyo lwe-radiographic kufuneka lwenziwe emva kwenkqubo yokudityaniswa.
