Hoʻopuka hana

(1) Hana hana:

①Ma lalo o 450 ℃ ka wela o ka hoʻohana ʻana o nā paipu kila no ka mea hoʻomomona, a ʻo nā paipu hale i hana nui ʻia me nā paipu kila i hoʻopaʻa ʻia i ka wela a i ʻole ke anu 10 # a me 20 #.

②Hoʻohana pinepine ʻia ka paipu kila kūikawā no ka mea hoʻomomona ma lalo o ke kiʻekiʻe kiʻekiʻe a me ke kaomi kiʻekiʻe, a e hoʻoheheʻe ʻia ka paipu ma lalo o ka hana o ke kinoea flue kiʻekiʻe a me ka mahu wai.Pono ka paipu kila e loaʻa i ka ikaika mau loa, ka oxidation kiʻekiʻe a me ke kūpaʻa corrosion, a me ke kūpaʻa hoʻonohonoho maikaʻi.

(2) Ke kumu:

①Hoʻohana nui ʻia nā paipu kila no ka hana ʻana i nā paipu pā wai, nā paipu wai paila, nā paipu mahu wela, nā paipu mahu no nā locomotive boilers, nā paipu uwahi nui a me nā paipu pilaka arch.

②Hoʻohana nui ʻia ka paipu kila i hoʻohana nui ʻia no ka hana ʻana i ka paipu superheater, reheater pipe, ea duct, main pipe pipe, etc.
