Injongo yethu iya kuba kukuzalisekisa abathengi bethu ngokunikela ngoncedo lwegolide, ixabiso elimangalisayo kunye nomgangatho ophezulu weUmbhobho weCarbon Steel waseTshayina kunye noMbhobho weCarbon, Sinoxanduva kakhulu kuzo zonke iinkcukacha kwi-odolo yabathengi bethu kungakhathaliseki kumgangatho wewaranti, amaxabiso anelisekile, ukuhanjiswa ngokukhawuleza, ukunxibelelana ngexesha, ukupakisha okwanelisekile, imigaqo yokuhlawula lula, imimiselo yokuthunyelwa kwempahla, emva kwenkonzo yokuthengisa njl. Sinika enye indawo yokumisa inkonzo kunye nokuthembeka okulungileyo kubo bonke abathengi bethu.Sisebenza nzima nabathengi bethu, oogxa bethu, abasebenzi ukwenza ikamva elingcono.
Umbhobho owenziwe phantsi kwesi nkcazo usetyenziselwa inkonzo yoxinzelelo oluphezulu kwi-atmospheric kunye neqondo lokushisa eliphantsi.Isetyenziswa kakhulu kwioli kunye nokuhanjiswa kwegesi yendalo.
I-ASTM A671LSAW(JCOE) iCarbon Steel Pipeiya kuba i-welded kabini, i-welds yokungena ngokupheleleyo eyenziwe ngokuhambelana neenkqubo kunye nabasebenzi be-welders okanye abaqhubi abafanelekileyo ngokuhambelana ne-ASME Boiler kunye noxinzelelo lweKhowudi yeVessel, iCandelo 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.
