Black annealed tube ye kika kya payipu y’ekyuma ekiyiringisibwa ennyogovu esinga okubunye okutuuka ku bbugumu ery’okusengejja, langi y’okungulu olw’ebbugumu eringi okukwatagana ne ttanka enjeru ey’empewo. Kungulu kwa kiddugavu kubanga tekubadde kusiigibwa. Mu kifo ky’okugenda mu maaso n’okukuumibwa okusobola okukuuma okukulukuta, ekyuma eky’ekika kino kiyita mu nkola y’okukyusa eddagala (blacking), ekozesebwa okukola ekyuma ekiddugavu ekiyitibwa iron oxide oba magnetite. Erinnya lyayo liva ku ndabika yaayo, langi enzirugavu olw’okusiiga ekyuma ekiyitibwa iron oxide.
Payipu y’ekyuma ekiddugavu (black annealed steel pipe) ye payipu y’ekyuma ebadde ekoleddwa mu ngeri ya ‘annealed’ (erongooseddwa mu bbugumu) okuggyawo situleesi yaayo ey’omunda, ekigifuula ey’amaanyi ate nga ya ductile. Enkola y’okukola ‘annealing’, erimu okubugumya payipu y’ekyuma ku bbugumu erimu n’oluvannyuma n’oginyogoza mpola, eyamba okukendeeza ku kutondeka enjatika oba obulema obulala mu kyuma, okuziyiza okukulukuta n’okulongoosa obuwangaazi bwa payipu.
Payipu z’ebyuma ebiddugavu ziwangaala era tezeetaagisa kuddaabiriza nnyo, ekizifuula ezisaanira: Okutuusa ggaasi ow’obutonde, okutambuza amafuta n’amafuta g’ebintu ebikadde, okutambuza omukka ogw’amaanyi, ebibikka waya z’amasannyalaze.
Okugatta ku ekyo, payipu z’ebyuma ebiddugavu nazo zikozesebwa mu makolero g’amafuta n’amafuta g’amafuta okuyiwa amafuta amangi nga ziyita mu bitundu ebyesudde. Era zikozesebwa okuzimba enkola z’okufukirira omuliro kubanga zisobola okugumira ebbugumu eringi.
