GB/T9948ʻO ka paipu kila seamless no ka haki ʻana o ka petroleum he paipu seamless kūpono no nā paipu umu, nā mea hoʻololi wela a me nā pipelines i loko o nā hale hoʻomaʻemaʻe petroleum. Hoʻohana ʻia ke kila kila kalapona kiʻekiʻe, ke kila kila alloy a me ke kila kila kūpaʻa wela kiʻekiʻe e hana i nā paipu paila mahu o ke kaomi kiʻekiʻe a ma luna. Hana kēia mau paipu paila ma lalo o ke ana wela a me ke kaomi, a ua hōʻike ʻia nā paipu i ka uahi wela kiʻekiʻe. E hana pū ʻia ka oxidation a me ka corrosion ma lalo o ka hana a ke kinoea a me ka mahu wai. No laila, pono nā paipu kila e loaʻa ka ikaika mau loa, ke kū'ē ʻana i ka oxidation kiʻekiʻe, a me ke kūpaʻa maikaʻi o ka hoʻonohonoho ʻana. Ma waho aʻe o ka hōʻoia ʻana i ka haku mele kemika a me nā waiwai mechanical, pono hoʻi nā paipu paila kiʻekiʻe e hana i ka hoʻāʻo kaomi hydraulic hoʻokahi, me nā hoʻāʻo hoʻonui a me ka hoʻopalahalaha. Hāʻawi ʻia nā paipu seamless kiʻekiʻe i kahi kūlana i mālama ʻia i ka wela.
Nā ʻano hana a me nā hana hana paipu haki ʻaila:

① Ma keʻano laulā, ʻo ka mahana lawelawe o nā paipu kila humuhumu ʻole ma lalo o 450°C. Hana nui ʻia nā paipu kūloko me ka No. 10, No. 20,12CrMo, 15CrMo, 12CrlMo, 12CrlMoV, 12Cr5MoI, 12Cr9MoI, nā paipu ʻōwili wela a i ʻole nā ​​paipu huki anu.

② Hoʻohana pinepine ʻia nā paipu kila humuhumu maʻamau GB9948 i nā kūlana wela kiʻekiʻe a me ke kaomi kiʻekiʻe. E oxidize a corrode nā paipu ma lalo o ka hana a ke kinoea flue wela kiʻekiʻe a me ka mahu wai. Pono nā paipu kila e loaʻa ka ikaika mau loa, ke kū'ē kiʻekiʻe i ka oxidation a me ka corrosion, a me ke kūpaʻa maikaʻi o ke kūkulu ʻana.

hoʻohana:

① Ma keʻano laulā, hoʻohana nui ʻia nā paipu kila humuhumu e hana i nā paipu paia wai, nā paipu wai e hoʻolapalapa ana, nā paipu mahu wela loa, nā paipu mahu wela loa no nā paila locomotive, nā paipu uahi nui a liʻiliʻi a me nā paipu piliki hoʻā, a pēlā aku.

Hoʻohana nui ʻia ka paipu kila humuhumu ②GB9948 e hana i nā paipu superheater, nā paipu reheater, nā paipu alakaʻi ea, nā paipu mahu nui, a me nā mea ʻē aʻe no nā paila kaomi kiʻekiʻe a me nā paila kaomi kiʻekiʻe loa.

Ua māhele ʻia nā paipu kila humuhumu maʻamau GB9948 i nā paipu paila maʻamau a me nā paipu paila kaomi kiʻekiʻe e like me kā lākou hana wela kiʻekiʻe. Inā he mau paipu paila maʻamau a i ʻole nā ​​​​paipu paila kaomi kiʻekiʻe, hiki ke māhele ʻia i nā paipu kila like ʻole e like me kā lākou mau koi hoʻohana like ʻole.
ʻO ke paipu kila wili ʻole GB/T9948, ke anawaena o waho he 10 ~ 426mm, ka mānoanoa o ka paia he 1.5 ~ 26mm. ʻO ke anawaena o waho a me ka mānoanoa o ka paia o nā paipu mahu wela loa, nā paipu uahi nui, nā paipu uahi liʻiliʻi a me nā paipu brick arch i hoʻohana ʻia i nā paila locomotive ua kuhikuhi ʻia ma nā ʻano ʻē aʻe.

ʻAno o ke ʻano: ʻAʻole ʻae ʻia nā māwae, nā pelu, nā ʻōwili, nā ʻōpala, nā delamination a me nā laina lauoho ma nā ʻili o loko a me waho o nā paipu kila. Pono e hoʻopau loa ʻia kēia mau kīnā. ʻAʻole e ʻoi aku ka hohonu o ka hoʻomaʻemaʻe ma mua o ka ʻokoʻa maikaʻi ʻole o ka mānoanoa o ka paia maʻamau, a ʻo ka mānoanoa maoli o ka paia ma kahi hoʻomaʻemaʻe ʻaʻole e emi ma mua o ka mānoanoa o ka paia i ʻae ʻia.
