Kupaka galvanizing ndi njira yogwiritsira ntchito zinc yoteteza ku chitsulo kapena chitsulo kuti zisawonongeke. Njirayi imagwiritsidwa ntchito kwambiri popanga mapaipi, makamaka omwe amagwiritsidwa ntchito m'mafakitale osiyanasiyana monga zomangamanga, mafuta ndi gasi, komanso madzi.Miyezo yopangira ma galvanizing pamapaipindizofunikira kwambiri pakuonetsetsa kuti mapaipi opangidwa ndi galvanizing ndi abwino komanso olimba. Tiyeni tikambirane mwatsatanetsatane za miyezo ya galvanizing ya mapaipi ndi tanthauzo lake mu mzere wa galvanizing wa mapaipi.
Kupaka mapaipiMiyezo imakhazikitsidwa makamaka ndi bungwe lapadziko lonse la American Society for Testing and Materials (ASTM). ASTM imakhazikitsa miyezo yeniyeni ya njira yopangira ma galvanizing, yomwe imaphatikizapo makulidwe a galvanizing wosanjikiza, kumatira kwa chophimbacho, ndi mtundu wonse wachopangidwa ndi chitsulopamwamba. Miyezo iyi ndi yofunika kwambiri kuti chitoliro cha galvanized chikhale cholimba komanso kuti chigwire ntchito bwino m'njira zosiyanasiyana.
Chimodzi mwa miyezo yofunika kwambiri ya chitoliro chopangidwa ndi galvanized ndi ASTM A123/A123M, yomwe imafotokoza zofunikira pa zophimba zopangidwa ndi galvanized pazinthu zachitsulo, kuphatikizapo mapaipi. Muyezo uwu umafotokoza makulidwe ocheperako a zophimba, kumatira ndi kumaliza kwa chitoliro chopangidwa ndi galvanized. Umaperekanso malangizo owunikira ndi kuyesazokutira zomatirakuonetsetsa kuti miyezo ikutsatira malamulo.
In mizere yopangira ma galvanizing ya chitoliro, kutsatira miyezo ya ASTM A123/A123M ndikofunikira kwambiri popanga chitoliro chapamwamba kwambiri cha galvanizing. Njira yopangira galvanizing nthawi zambiri imakhala ndi magawo angapo, kuphatikizapo kukonza pamwamba, kuviika galvanizing ndi kuipitsa pambuyo pake. Gawo lililonse liyenera kutsatira miyezo ya ASTM kuti likwaniritse makulidwe ndi mtundu wofunikira wa glazing.
Kukonzekera pamwamba kumaphatikizapo kuyeretsa mapaipi kuti achotse dzimbiri, mamba kapena zonyansa zina zomwe zingalepheretsekupopera magetsiGawo ili ndi lofunika kwambiri kuti zitsimikizire kuti zimamatira bwinochophimba cholimbaKuika mapaipi pamwamba pa chitoliro. Njira yothira ma galvanizing m'madzi otentha imaphatikizapo kumiza mapaipi oyeretsedwa mu bafa la zinc yosungunuka, yomwe imalumikizana ndi chitsulo kuti ipange chophimba choteteza..
Pambuyo pa ndondomeko yopangira ma galvanizing, chitolirocho chidzakonzedwanso pambuyo pake, zomwe zingaphatikizepo kuzimitsa, kuletsa kapena kuyang'ana makulidwe ndi kumatira kwa chophimbacho. Njira zokonzekera izi pambuyo pake ndizofunikira kwambiri kuti zitsimikizire kuti chitoliro cha galvanizing chikukwaniritsa zofunikira za miyezo ya ASTM ndipo chili chokonzeka kugwiritsidwa ntchito m'njira zosiyanasiyana.
Kutsatirakupopera mapaipiMiyezo sikuti imangotsimikizira ubwino ndi kulimba kwa chitolirocho, komanso imathandizira kuti chigwire ntchito kwa nthawi yayitali komanso kuti chisagwe ndi dzimbiri. Chitoliro chopangidwa ndi galvanized chogwirizana ndi ASTM ndi choyenera panja, pamalo omwe pali chinyezi chambiri komanso malo owononga, zomwe zimapangitsa kuti chikhale choyenera kugwiritsidwa ntchito monga kugawa madzi, kuthandizira kapangidwe kake komanso mapaipi a mafakitale.
Mwachidule, miyezo yogwiritsira ntchito ma galvanizing a mapaipi yomwe yafotokozedwa ndi ASTM International imagwira ntchito yofunika kwambiri pakupanga ma galvanizing a mapaipi. Kutsatira muyezo uwu kumatsimikizira kutichitoliro cha galvanizedikukwaniritsa zofunikira zofunika pakukhuthala, kumatira komanso ubwino wonse. Potsatira miyezo ya ASTM,opangaakhoza kupangachitoliro chapamwamba kwambiri cha galvanizedzomwe zimapereka chitetezo chapamwamba cha dzimbiri komanso nthawi yogwira ntchito m'mafakitale ndi m'mabizinesi osiyanasiyana.
