Ukuzingisa “kuMgangatho oPhezulu oPhezulu, ukuhanjiswa okukhawulezayo, ixabiso elinobundlongondlongo”, siseke intsebenziswano yexesha elide kunye nabathengi abavela phesheya kolwandle kunye nasekhaya kwaye sifumana amagqabantshintshi amatsha kunye namadala aphezulu odumo oluphezulu DIN1629 St37 St44 St52 S355j2h iSeamless Carbon Steel. Pipe, Siyakumema nobabini kunye neshishini lakho ukuba niphumelele kunye nathi kwaye nabelane ngexesha elide elidlamkileyo kwicandelo lehlabathi.
Ukuzingisa “kumgangatho ophezulu ophakamileyo, ukuhanjiswa ngokukhawuleza, ixabiso elinobundlongondlongo”, siye saseka intsebenziswano yexesha elide kunye nabathengi abavela phesheya kolwandle nasekhaya kwaye sifumana amagqabantshintshi aphezulu kunye nabathengi abadala.Imibhobho yaseTshayina engenamthungo kunye noMbhobho wentsimbi, Sijonge ukuba lishishini langoku elinombono worhwebo "wokunyaniseka kunye nokuzithemba" kunye nenjongo "yokubonelela abathengi ngeenkonzo ezinyanisekileyo kunye neemveliso ezisemgangathweni".Sicela ngokunyanisekileyo ngenkxaso yakho engatshintshiyo kwaye siyayixabisa ingcebiso yakho yobubele kunye nesikhokelo.
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.
Iziphelo: Isiphelo esicacileyo, iSiphelo esiBeveled, esiGrooved;
