Kwicandelo lokulwa nokugqwala kwemibhobho yentsimbi, umgangatho wokugquma uchaphazela ngokuthe ngqo ubomi benkonzo kunye nokhuseleko lokusebenza kombhobho. I-FBE ARO Coating (i-fused epoxy powder coating) njengesisombululo sokulwa nokugqwala esisebenzayo nesithembekileyo sisetyenziswe kakhulu kwiiprojekthi ezinje ngokubonelela ngamanzi, ukuthuthwa kweoyile, ukuhanjiswa kwegesi, kunye nonyango lwelindle.
Ukwaleka kwe-FBE AROyi-thermosetting coating ye-powder eyomileyo enecandelo elinye. Xa isebenza ngokufudumeza, ifumana i-chemical reaction kumphezulu wombhobho wentsimbi, yenze umaleko okhuselekileyo oxineneyo ngelixa igcina iipropati zayo ezintle zomzimba nezekhemikhali. Ukususela ngeminyaka yoo-1960, ububanzi bokusetyenziswa kobu buchwepheshe buhlala busanda. Kule mihla, ingasetyenziselwa ukulwa nokugqwala kodonga lwangaphakathi nolwangaphandle lwemibhobho yentsimbi enobubanzi obukhulu, igubungela imibhobho edibeneyo ye-spiral (SSAW), imibhobho edibeneyo ye-straight seam (ERW/LSAW), imibhobho engenamthungo, kunye nezixhobo zemibhobho ezinjengeengqiniba, ii-tee, kunye nee-reducers.
Ngokwemigangatho,Imigangatho yokuGcoba ye-FBENgokuyintloko landela imiqathango ebekwe yi-American Water Works Association (AWWA). Lo mgangatho umisela i-epoxy coating kunye ne-lining yombhobho wamanzi wentsimbi, kwaye wenzelwe ukubonelela ngokuzithemba kumandla e-coating okukhusela ekungcoleni. Ii-FBE coatings ezizalisekisa lo mgangatho ziya kubonelela ngokhuseleko lwexesha elide kwimibhobho ekukhukulisekeni okubangelwa ngumhlaba, umzimba wamanzi kunye ne-chemical medium, nto leyo ekhokelela kubomi benkonzo obongezelelweyo benkqubo yemibhobho.
Njengomthengisi wemveliso, iCangzhou Spiral Steel Pipe Group Co., Ltd. yeyona nkampani ibalaseleyo yokuvelisa iipayipi zentsimbi ezijikelezayo kunye neemveliso zokugquma iipayipi zentsimbi eTshayina. Yasekwa ngo-1993, le nkampani ikwiSixeko saseCangzhou, kwiPhondo laseHebei. Inendawo yeemitha zesikwere ezingama-350,000 kunye nee-yuan ezingama-68 ezigidi zeempahla kunye nabasebenzi abangaphezu kwama-680 okwangoku. Le nkampani ivelisa iitoni ezingama-400,000 zeepayipi zentsimbi ezijikelezayo ngonyaka ezinexabiso lonyaka le-yuan elizizigidi ezili-180.
I-Cangzhou Spiral Steel Pipe Group iyaziqhelanisa ne-FBE Coating Standards ukuvelisa iimveliso ze-FBE ARO Coating ezinamava okubonelela ngezisombululo zemibhobho yentsimbi yokulwa nokugqwala ezikumgangatho ophezulu kubathengi basekhaya nakwamanye amazwe. Nokuba yiMibhobho yoNikezo lwaManzi eSixeko, iiMibhobho yeoyile kunye neGesi ezikude, okanye iNkqubo yoMbane yokujikeleza kwamanzi kwiZinto eziShishino, iimveliso zethu ngokuqinisekileyo aziyi kukuphoxa.
Ukuba unemibuzo malunga nemveliso okanye malunga neeparameter zobugcisa, ungaqhagamshelana nathi nangaliphi na ixesha.
