    Hoʻohana nui ia no ka hana ʻana i ke kila kila kila kiʻekiʻe, ke kila hoʻoheheʻe ʻia a me ke kila wela-kū ʻole i nā paipu kila maʻemaʻe no ke kaomi kiʻekiʻe a ma luna o nā paipu paila mahu.

    Hoʻohana nui ʻia no ke kiʻekiʻe kiʻekiʻe a me ka lawelawe wela o ka paila (Superheater tube, reheater tube, ea alakaʻi paipu, pahu mahu nui no nā boiler kiʻekiʻe a kiʻekiʻe). Ma lalo o ka hana o ke kinoea flue wela kiʻekiʻe a me ka mahu wai, e oxidize a corrode ka paipu. Pono ka paipu kila i ke kūpaʻa kiʻekiʻe, ke kūpaʻa kiʻekiʻe i ka oxidation a me ka corrosion, a me ka paʻa paʻa.
