A53 kiʻekiʻe puʻe seamless kila paipu mea hana
A53 seamless kila paipu mea he mea o American maʻamau kila paipu, ma ka a53-a ua like me ka home 10 # kila, a53-b ua like me ka hale 20 # kila, a me a53-f ua like me ka home Q235 mea. ʻO nā kaʻina hana nui o A53 seamless steel pipe he kiʻi anu a me ka ʻōwili wela. ʻO ka ʻokoʻa nui ma waena o nā mea ʻelua, ʻo ke kaʻina hana o ka paipu kila liʻiliʻi i ʻōwili ʻia i ke anuanu ʻoi aku ka paʻakikī ma mua o ka ʻōwili wela. I ka nānā 'ana, 'oi aku ka pōkole o ka paipu kila li'ili'i ma mua o ka paipu kila ma'ema'e. ʻOi aku ka liʻiliʻi o ka mānoanoa o ka pā o ka paipu kila liʻiliʻi i ʻōwili ʻia ma mua o ka paipu kila liʻiliʻi wela, akā ʻoi aku ka mālamalama o ka ʻili. ʻO ka ʻili o ka paipu kila i ʻōwili ʻia he ʻōkeke. ʻO ke kaʻina hana nui, ʻo ia ka puʻupuʻu pōʻai pōʻai → hoʻomehana → perforation → ʻekolu ʻōwili keʻa o ka ʻōwili, ʻōwili mau a extrusion → ka hoʻohemo ʻana i ka paipu → ka nui (a i ʻole ka hoʻohaʻahaʻa ʻana) → hoʻomaʻamaʻa → hoʻopololei → hoʻāʻo hydrostatic (a ʻike hewa paha) → hōʻailona → hale kūʻai. Ka helu helu o ke kaumaha no ka mika o A53 seamless steel paipu: 0.02466 * paia mānoanoa * (waho anawaena - paia mānoanoa).
ʻO ke kiʻekiʻe kiʻekiʻe seamless steel paipu a me ke kiʻekiʻe kaomi boiler paipu mea he 'ano o ka paila paipu, no ka waeʻano o seamless kila paipu. ʻO keʻano o ka hanaʻana ua like ia me ka paipuʻole, akā aia nā koi koʻikoʻi no ka pae kila i hoʻohanaʻia i ka hanaʻana i ka paipu kila. Hoʻohana pinepine ʻia nā paipu boiler kiʻekiʻe ma lalo o ke kiʻekiʻe kiʻekiʻe a me nā kūlana kiʻekiʻe. Hoʻohana nui ʻia nā paipu paila kiʻekiʻe no ka hana ʻana i nā paipu superheater, nā paipu reheater, nā ʻea ea, nā pahu mahu nui, etc.
ʻO nā paipu paila haʻahaʻa haʻahaʻa a haʻahaʻa gb3087-2008 a me nā paipu paila kiʻekiʻe GB5310-2008 he kiʻekiʻe kiʻekiʻe carbon structural kila wela-wili a huki anu (rolled) seamless steel paipu no ka hana ʻana i nā paipu mahu superheated, paila wai o ka haʻahaʻa a me ke kiʻekiʻe. nā paila me nā ʻano hana like ʻole a me nā paipu mahu wela loa, nā paipu uwahi nui, nā paipu uwahi liʻiliʻi a me nā paipu pōhaku lepo no nā paila locomotive. ʻO ka paipu kila maʻemaʻe no ka hoʻolālā (GB / t8162-2008) he paipu kila maʻemaʻe no ka hana maʻamau a me ka hana mechanical.
ʻO ka kikoʻī a me ka hiʻohiʻona maikaʻi: GB5310-2008 mau paipu kila ʻole no nā paila kiʻekiʻe, ʻo ke anawaena o waho o nā paipu i ʻōwili ʻia he 22 ~ 530mm, a ʻo ka mānoanoa o ka pā he 20 ~ 70mm. ʻO ke anawaena o waho o 10 ~ 108mm a me ka mānoanoa o ka pā o 2.0 ~ 13.0mm.
ʻO ka paipu kila maʻemaʻe keʻano kūikawā ka inoa nui o ka paipu kila maʻemaʻe me nāʻano'āpana'ē aʻe koe ka paipu pōʻai. E like me ka ʻokoʻa a me ka nui o ka pauku paipu kila, hiki ke hoʻokaʻawale ʻia i loko o ka mānoanoa like o ka pā ʻano like ʻole ke ʻano o ka paipu kila liʻiliʻi (code D), ka mānoanoa like ʻole o ka pā ʻano like ʻole o ka paipu kila liʻiliʻi (code BD) a me ke anawaena hoʻololi kūikawā. paipu kila ʻole (code BJ). Hoʻohana nui ʻia ka paipu kila seamless kūikawā i nā ʻāpana like ʻole, nā mea hana a me nā ʻāpana mechanical. Ke hoʻohālikelike ʻia me ka paipu pōʻai, ʻoi aku ka nui o ka manawa o ka inertia a me ka modulus pauku, a ʻoi aku ka nui o ke kūlou ʻana a me ke kūpaʻa ʻana, hiki ke hoʻemi nui i ke kaumaha o ke kino a mālama i ke kila:
(1) Loaʻa nā māka kila kila kila kiʻekiʻe me 20g, 20mng a me 25mng.
(2) Alloy structural steel grades: 15mog, 20mog, 12crmog, 15CrMoG, 12CR2MOG, 12crmovg, 12Cr3MoVSiTiB, etc.
(3) Ma waho aʻe o ka hōʻoia ʻana i ka haku mele ʻana a me nā waiwai mechanical, ʻo 1Cr18Ni9 a me 1cr18ni11nb boiler tubes i hoʻohana mau ʻia i ke kila wela ʻeleʻele e hoʻokō ʻia i ka hoʻāʻo hydrostatic, flaring a flattening hoʻāʻo hoʻokahi. Hāʻawi ʻia nā paipu kila ma ke ʻano wela.
Eia kekahi, aia kekahi mau koi no ka microstructure, ka nui o ka palaoa a me ka papa decarburization o ka paipu kila i hoʻopau ʻia.
