Siqhubeka "nomgangatho ophezulu, ukuhanjiswa ngokukhawuleza, ixabiso elinamandla", siqalise intsebenziswano yexesha elide nabathengi abavela kwamanye amazwe nasekhaya kwaye sifumana izimvo ezilungileyo zabathengi abatsha nabadala zeDin1629 St37 St44 St52 S355j2h Seamless Carbon Steel Pipe, Siyakumema wena kunye neshishini lakho ukuba niphumelele kunye nathi kwaye nibe negalelo elibonakalayo kwixesha elide kwihlabathi liphela.
Sihlala sisenza “umgangatho ophezulu, ukuhanjiswa ngokukhawuleza, ixabiso elinobundlongondlongo”, siqalise intsebenziswano yexesha elide nabathengi abavela kwamanye amazwe nasekhaya kwaye sifumana izimvo ezilungileyo zabathengi abatsha nabadala.Iipayipi Ezingenamthungo zaseTshayina kunye nePipe yeNsimbi, Sijonge ukuba lishishini lanamhlanje elinombono wezorhwebo "wokunyaniseka nokuzithemba" kwaye sinenjongo "yokubonelela abathengi ngeenkonzo ezinyanisekileyo kunye neemveliso ezisemgangathweni ophezulu". Sicela ngokunyanisekileyo inkxaso yakho engaguqukiyo kwaye siyayixabisa ingcebiso yakho yobubele kunye nesikhokelo.
Imibhobho e-odolwe phantsi kolu luhlu isetyenziselwa inkonzo yoxinzelelo oluphezulu kumaqondo obushushu aphantsi naphakathi komoya. Isetyenziswa kakhulu ekudluliseni ioyile kunye negesi yendalo.
I-ASTM A671Umbhobho wentsimbi yekhabhoni we-LSAW(JCOE)kufuneka zibe zii-welds ezidityaniswe kabini, ezifakwe ngokupheleleyo ezenziwe ngokuhambelana neenkqubo kunye nabashicileli okanye abaqhubi be-welding abafanelekileyo ngokuhambelana ne-ASME Boiler kunye neKhowudi yeVessel yoxinzelelo, iCandelo IX.
Zonke iindidi ngaphandle kwe-10, 11, 12 kunye ne-13 maziphathwe ngobushushu kwi-oven elawulwa ukuya kwi-±15℃ kwaye zixhotyiswe nge-hydrometer yokurekhoda ukuze iirekhodi zokufudumeza zifumaneke.
