Ngoku sinezakhono, iqela lokusebenza ukubonelela ngeenkonzo ezisemgangathweni kubathengi bethu.Sihlala silandela itenet yomthengi, ejolise kwiinkcukachaYaseTshayina LSAW/SSAW uMbhobho weNtsimbi kunye noMbhobho oDidiweyo, Injongo yethu kukuzisa ixabiso eliphezulu rhoqo kubathengi bethu kunye nabathengi babo.Oku kuzibophelela kungena kuyo yonke into esiyenzayo, kusiqhubela ekubeni siphuhlise ngokuqhubekayo kwaye siphucule izisombululo zethu kunye neenkqubo zokuzalisekisa iimfuno zakho.
Umbhobho owenziwe phantsi kwesi nkcazo usetyenziselwa inkonzo yoxinzelelo oluphezulu kwi-atmospheric kunye neqondo lokushisa eliphantsi.Isetyenziswa kakhulu kwioli kunye nokuhanjiswa kwegesi yendalo.
I-ASTM A671 LSAW(JCOE) I-Carbon Steel Pipe iyakudityaniswa kabini, i-welds engena ngokuzeleyo eyenziwe ngokuhambelana neenkqubo kunye nabaluqili okanye abasebenzisa i-welding abafanelekileyo ngokuhambelana ne-ASME Boiler kunye noxinzelelo lweKhowudi yeVessel, iCandelo le-IX.
Zonke iiklasi ngaphandle kwe-10, i-11, i-12 kunye ne-13 iya kuphathwa ukushisa kwisithando somlilo esilawulwa kwi-±15℃ kwaye ixhotyiswe nge-hydrometer yokurekhoda ukwenzela ukuba iirekhodi zokufudumeza zifumaneke.
Ukwenziwa: LSAW(JCOE) Imibhobho yentsimbi
Ubungakanani : OD: 406 ~ 1500mm WT: 6 ~ 40mm
IBakala: CB60, CB65, CC60, CC65, njl.
Ubude: 12M okanye ubude obuchaziweyo njengoko kufuneka.
