Ukugaya ngentsimbi yinkqubo yokufaka umaleko okhuselayo we-zinc kwintsimbi okanye kwisinyithi ukuthintela ukugqwala. Le nkqubo isetyenziswa kakhulu ekwenzeni imibhobho, ingakumbi leyo isetyenziswa kumashishini ahlukeneyo afana nokwakha, ioyile negesi, kunye nokubonelela ngamanzi.Imigangatho yokubopha imibhobho nge-galvanizingzibalulekile ekuqinisekiseni umgangatho kunye nokuqina kwemibhobho ye-galvanizing. Makhe singene kwiinkcukacha zemigangatho ye-galvanizing yemibhobho kunye noko ithetha kona kumgca we-galvanizing yemibhobho.
Ukugaya iipayipiimigangatho imiselwe kakhulu yi-American Society for Testing and Materials (ASTM) international unit. I-ASTM imisela imigangatho ethile yenkqubo yokugaya i-galvanizing, equka ubukhulu bomaleko we-galvaning, ukunamathela kwe-coating, kunye nomgangatho uwonke we-i-galvanizedumphezulu. Le migangatho ibalulekile ekugcineni ukuthembeka kombhobho we-galvanized kunye nokuqinisekisa ukusebenza kwawo kwiindlela ezahlukeneyo zokusebenza.
Omnye wemigangatho ephambili yepayipi egalelweyo yi-ASTM A123/A123M, echaza iimfuno zepeyinti egalelweyo kwiimveliso zentsimbi, kuquka iipayipi. Lo mgangatho uchaza ubuncinci bobukhulu bepeyinti, ukunamathela kunye nokugqitywa kwepayipi egalelweyo. Ikwabonelela ngezikhokelo zokuhlolwa nokuvavanywa kweiingubo ezigqunyiweyoukuqinisekisa ukuthotyelwa kwemigangatho.
In imigca yokugaya iipayiphu, ukuthobela imigangatho ye-ASTM A123/A123M kubalulekile ekuveliseni umbhobho we-galvaning okumgangatho ophezulu. Inkqubo ye-galvaning idla ngokubandakanya amanqanaba aliqela, kuquka unyango lomphezulu, i-hot-dip galvanizing kunye ne-post-processing. Inqanaba ngalinye kufuneka linamathele kwimigangatho ye-ASTM ukuze kufezekiswe ubukhulu kunye nomgangatho we-coating ofunekayo.
Ukulungiswa komphezulu kubandakanya ukucoca imibhobho ukususa naluphi na ugqwala, isikali okanye ezinye izinto ezingcolileyo ezinokuthintelaukugaya nge-galvanizingleya ekunamatheleni. Eli nyathelo libalulekile ukuqinisekisa ukunamathela ngokufanelekileyougqubuthelo olugqunyiweyokumphezulu wombhobho. Inkqubo yokuntywila ngobushushu ibandakanya ukuntywilisela imibhobho ecocekileyo kwibhafu ye-zinc enyibilikisiweyo, ethi inamathele kwintsimbi ukuze yenze uphahla olukhuselayo..
Emva kwenkqubo yokugaya i-galvanizing, umbhobho uza kuqhubeka nokulungiswa emva kokusetyenziswa, okunokubandakanya ukucima, ukudlulisa okanye ukujonga ubukhulu kunye nokunamathela kwengubo. La manyathelo okulungisa emva kokusetyenziswa abalulekile ukuqinisekisa ukuba umbhobho we-galvanizing uyahlangabezana neemfuno zemigangatho ye-ASTM kwaye ulungele ukusetyenziswa kwiindlela ezahlukeneyo zokusebenza.
Ukuthobelaukugalela ngentsimbi yombhobhoimigangatho ayiqinisekisi nje kuphela umgangatho kunye nokuqina kombhobho, kodwa ikwanegalelo ekusebenzeni kwawo ixesha elide kunye nokumelana nokugqwala. Umbhobho we-galvanized ohambelana ne-ASTM ufanelekile kwiindawo zangaphandle, ezinomswakama ophezulu kunye neendawo ezigqwalayo, okwenza ukuba ube ngofanelekileyo kwizicelo ezifana nokusasazwa kwamanzi, inkxaso yesakhiwo kunye neenkqubo zepayipi zoshishino.
Ngamafutshane, imigangatho yokugaya iipayipi echazwe yi-ASTM International idlala indima ebalulekileyo kumgca wokuvelisa i-galvanizing pipe. Ukuthobela lo mgangatho kuqinisekisa ukubaumbhobho we-galvanizedihlangabezana neemfuno ezifunekayo zobukhulu bengubo, ukunamathela kunye nomgangatho ngokubanzi. Ngokulandela imigangatho ye-ASTM,abavelisiinokuvelisaumbhobho we-galvanized okumgangatho ophezuluebonelela ngokhuseleko oluphezulu lokugqwala kunye nobomi benkonzo kwiintlobo ngeentlobo zezicelo zoshishino nezezorhwebo.
