Payipu z’ekyuma bwe zibeera mu mpewo ne ziyita mu nsengekera z’okwokya (oxidation reactions) ne okisigyeni oba zikuluggusibwa ebirungo bya okisigyeni mu mazzi okukola okisayidi, zijja kusamba. Payipu z’ekyuma ezikoleddwa mu galvanized zikozeseddwa galvanization ku payipu z’ekyuma, ne zikola layeri ya galvanized eyawula empewo, bwe kityo ne zibeera zisinga okukulukuta-ezigumira ate nga tezitera kufuuka buwuka. Kale, payipu za galvanized zinaafuuka obusagwa?
Okutwalira awamu, payipu z’ekyuma ezikoleddwa mu galvanized zimala butabeera na buzaale, naye tekitegeeza nti tezijja kufuuka nfuufu n’akatono. Ensonga ya kaseera buseera. Oluvannyuma lw’okukozesa term okumala ebbanga eddene-, payipu ezikoleddwa mu galvanized zijja kuba zikyali za buwuka. Okugatta ku ekyo, singa obutonde we bukozesebwa buba bunnyogovu nnyo oba nga buba bufunye enkuba okumala ebbanga eddene, n’ebirala, payipu z’ekyuma ezikoleddwa mu galvanized zijja kulaga mangu oxidation n’amabala, olwo obusagwa bujja kubaawo.
Okugatta ku ekyo, waliwo ebika bibiri ebya payipu z’ekyuma eziyitibwa galvanized: ezibuguma-Siikiza payipu za galvanized ne payipu za galvanized ennyogovu. Relatively, hot-Dipu payipu ezikoleddwa mu galvanized tezitera kuba na buwuka okusinga payipu ezinnyogovu ezikoleddwa mu galvanized.
