Amapayipi e-hot-dip galvanized akhiqizwa ngepayipi lensimbi ye-carbon kanye ne-zinc coating. Inqubo ihilela ukugeza i-asidi ipayipi lensimbi ukuze kukhishwe noma yikuphi ukugqwala noma i-oxidation, ukulihlanza ngesisombululo se-ammonium chloride, i-zinc chloride, noma inhlanganisela yakho kokubili ngaphambi kokucwiliswa kubhavu oshisayo wediphu. Okuwumphumela wokunamathela othayela kufana, kunamathela kakhulu, futhi kunokumelana okuphezulu nokugqwala ngenxa yokusabela okuyinkimbinkimbi ngokomzimba namakhemikhali okwenzeka phakathi kwe-substrate yensimbi kanye ne-zinc encibilikisiwe yokunamathela. Ungqimba lwe-alloy luhlangana nongqimba lwezinc oluhlanzekile kanye ne-substrate yepayipi lensimbi, okunikeza ukumelana okuhle kakhulu nokugqwala.
Amapayipi othayela oshisayo asetshenziswa kakhulu emikhakheni ehlukahlukene efana nezindawo zokugcina izithombo zezolimo, ukuvikela umlilo, ukuhlinzekwa kwegesi, nezinhlelo zokudonsa amanzi.
