Ngoku sineqela elinobuchule nelisebenzayo lokubonelela abathengi bethu ngeenkonzo ezisemgangathweni. Sihlala silandela umgaqo-nkqubo ojolise kubathengi, ogxile kwiinkcukacha.Umbhobho wentsimbi waseTshayina i-LSAW/SSAW kunye nombhobho odibeneyo, Injongo yethu kukubonelela ngexabiso eliphakamileyo rhoqo kubathengi bethu nakubathengi babo. Olu kuzinikela luchaphazela yonke into esiyenzayo, lusishukumisela ukuba siqhubeke nokuphuhlisa nokuphucula izisombululo zethu kunye neenkqubo zokuzalisekisa iimfuno zakho.
Imibhobho e-odolwe phantsi kolu luhlu isetyenziselwa inkonzo yoxinzelelo oluphezulu kumaqondo obushushu aphantsi naphakathi komoya. Isetyenziswa kakhulu ekudluliseni ioyile kunye negesi yendalo.
Umbhobho wentsimbi yekhabhoni we-ASTM A671 LSAW(JCOE) kufuneka ube zii-welds ezifakwe kabini, ezifakwe ngokupheleleyo ezenziwe ngokuhambelana neenkqubo kunye nabashicileli okanye abaqhubi bokushisela 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.
