Pāpaʻa hao haohe papa kila welded me ka wela wela a i ʻole ka uila galvanized layer ma luna o ka ʻili, i hoʻohana nui ʻia i ke kūkulu ʻana, nā mea hana hale, nā kaʻa a me nā moku, ka hana ipu, ka ʻoihana electromechanical a pēlā aku.
1.Hale kila
Hoʻohana nui ia no ka hana ʻana i nā hale kila, nā alahaka, nā moku a me nā kaʻa.
2. Ke kila welu
ʻO ka hoʻohuiʻana i nā mea kūikawā (P, Cu, C, a me nā mea'ē aʻe) he maikaʻi ke kū'ēʻana i ka corrosion a me ke kū'ēʻana o ka atmospheric corrosion, a hoʻohanaʻia i ka hanaʻana i nā pahu, nā kaʻa kūikawā, a me nā hale kūkulu.
3. Hot'ōwili kila kūikawā
Hoʻohana ʻia ke kila kalapona, ke kila kila a me ke kila mea hana no ka hana ʻana i nā ʻāpana mīkini like ʻole ma hope o ka ʻenehana mālama wela.
4.Papa kilano ka paipu kila
Loaʻa iā ia ka hana hoʻoponopono maikaʻi a me ka ikaika compressive, a hiki ke hoʻohana ʻia e hana i nā kīʻaha kiʻekiʻe kiʻekiʻe o ke kinoea me nā mea ma lalo o 500L piha me LPG, acetylene a me nā kinoea like ʻole.
