Hana hana
1. Aia ma lalo o 450 ℃ ka wela o ka paila paila ma lalo o 450 ℃, hana nui ʻia ka paipu home ma No. 10, ʻaʻole.20 carbon bonded steel pipe hot rolled paipu hukihuki anu.
2. Hoʻohana pinepine ʻia nā paipu paila kiʻekiʻe ma lalo o ke kiʻekiʻe kiʻekiʻe a me nā kūlana kiʻekiʻe.Ma lalo o ka hana o ke kinoea flue wela kiʻekiʻe a me ka mahu wai, e hiki mai ka oxidation a me ka corrosion.Pono ka paipu kila e loaʻa ka ikaika lōʻihi kiʻekiʻe, ke kūpaʻa ʻana i ka corrosion oxidation kiʻekiʻe a me ke kūpaʻa microstructure maikaʻi.
3. ʻO ke kiʻekiʻe kiʻekiʻe puʻu paila he ʻano o ka paila paila, no ka ʻāpana kila ʻole.ʻO ke ʻano hana like me ka seamless tube high pressure boiler tube, akā aia nā koi koʻikoʻi ma ka pae o ke kila i hoʻohana ʻia no ka hana ʻana i ka paipu kila.Hoʻohana pinepine ʻia nā paipu paila kiʻekiʻe ma lalo o ke kiʻekiʻe kiʻekiʻe a me nā kūlana kiʻekiʻe.Hoʻohana nui ʻia ka paipu paila kiʻekiʻe no ka hana ʻana i ka tube superheater, tube reheater, paipu conduit, paipu mahu nui a pēlā aku o ke kiʻekiʻe kiʻekiʻe a me ka ultra high pressure boiler.
4. No ka mea, e hana ana ka paila paila ma lalo o ke kiʻekiʻe o ka mahana a me ke kaomi kiʻekiʻe no ka manawa lōʻihi, e kolo ana nā mea, ka emi ʻana o ka plasticity a me ka paʻakikī, ka hoʻololi ʻana o ka hui kumu, ka ʻino a pēlā aku.ʻO nā paipu kila i hoʻohana ʻia ma ke ʻano he boiler e loaʻa:
(1) Ka ikaika lōʻihi kūpono;
(2) Hiki ke hoʻololi i ka plastic plastic;
(3) ʻO ka liʻiliʻi o ka wā kahiko a me ka brittleness thermal;
(4) High oxidation kū'ē, lanahu lehu kū'ē, kiʻekiʻe wela kū'ē i maoli kinoea corrosion, mahu a me stress corrosion hana;
(5) Paʻa hoʻonohonoho maikaʻi a me ka hana kaʻina hana maikaʻi.
ʻO ke kila o ke kiʻekiʻe puʻupuʻu boiler tube he carbon steel a me ka pearlite, ferritic a me austenitic stainless steel heat resistant steel.I mea e hoʻomaikaʻi ai i ka maikaʻi wela o nā ʻāpana hana wela a hōʻemi i ka hoʻohana ʻana i ka wahie, ʻo ka hoʻomohala ʻana i ka mana nui, ke kiʻekiʻe kiʻekiʻe (kiʻekiʻe kiʻekiʻe, kiʻekiʻe kiʻekiʻe) nā mana hana wela (ʻoi aku ma mua o 1000MW) i hāʻawi mua ʻia i ka honua.Ua hoʻonui ʻia ke kaomi mahu i ka 31.5 ~ 34.3MPa, ka wela wela wela a hiki i 595 ~ 650 ℃, i ka hoʻomohala ʻana i ka puʻuwai koʻikoʻi ultra-kiʻekiʻe, no laila ua hoʻokomo ʻia ka pahu boiler kiʻekiʻe.Ua hoʻomohala ʻia kahi papa kila hou e hoʻokō i ke koi o ka paila kīwila kiʻekiʻe.
High pressure boiler tube production manufacturing method，E hoʻohana i ka helu
No ka paila haʻahaʻa a me ka haʻahaʻa puʻupuʻu (ʻoi aku ka nui o ke kaomi hana ma mua o 5.88mpa, ka mahana hana ma lalo o 450 ℃) ka paipu wela wela;Hoʻohana ʻia no ka paila kīʻaha kiʻekiʻe (ke kaomi hana ma luna o 9.8mpa, ka mahana hana ma waena o 450 ℃ ~ 650 ℃) hoʻomehana honua paipu, economizer, superheater, reheater, petrochemical pipe, etc.
E like me ka haku mele 'ana o ka mea hiki ke maheleia i loko o 20G kiʻekiʻe-puʻe boiler paipu, 12Cr1MoVG kiʻekiʻe-puʻe boiler paipu, hao noiʻi 102 kiʻekiʻe-puʻe boiler paipu, 15CrMoG kiʻekiʻe-puʻe boiler paipu, 5310 kiʻekiʻe-press boiler paipu, 3087 paipu paila ha'aha'a ha'aha'a a ha'aha'a, 40Cr paipu paila ki'eki'e, 1Cr5Mo paipu paila ki'eki'e, 42CrMo paipu paila ki'eki'e.
High pressure boiler tube production method manufacturing ， Nā kikoʻī a me ka maikaʻi o ka helehelena
(1) GB3087-2008 "paipu kila maʻemaʻe no ka paila haʻahaʻa haʻahaʻa a waena".ʻO nā kikoʻī o nā paipu kila no nā ʻano paila like ʻole, nā anawaena 10 ~ 426mm, 43 mau ʻano i ka huina.He 29 mau ʻano o ka mānoanoa pā mai 1.5 mm a i 26mm.Eia naʻe, ʻo ke anawaena o waho a me ka mānoanoa o ka pā o ka paipu mahu wela nui, ka paipu uwahi nui, ka paipu uwahi liʻiliʻi a me ka paipu pōhaku lepo i hoʻohana ʻia i loko o ka paila locomotive.
(2) GB5310-2008 "Seamless Steel Tube no High Press Boiler" wela olokaa paipu anawaena 22 ~ 530mm, paia mānoanoa 20 ~ 70mm.Anuanu huki (anu olokaa) paipu anawaena 10 ~ 108mm, paia mānoanoa 2.0 ~ 13.0mm.
(3) GB3087-82 "puʻu kila maʻemaʻe no ka paila haʻahaʻa a me waena o ka paila" a me ka GB5310-95 "pahu kila maʻemaʻe no ka paila kiʻekiʻe".ʻO ka maikaʻi o ka hiʻohiʻona: ʻaʻole ʻae ʻia nā māwae, ka pelu ʻana, ka ʻōwili, ka ʻili, ka hoʻokaʻawale ʻana a me nā wrinkles ma ka ʻaoʻao o loko a me waho o ka paipu kila.Pono e hoopau loa ia keia mau hemahema.ʻAʻole ʻoi aku ka hohonu o ka hoʻomaʻemaʻe ma mua o ka ʻae ʻole ʻana o ka mānoanoa o ka paia nominal, a ʻo ka mānoanoa maoli o ka pā ma ka ʻae ʻana ʻaʻole e emi iho ma mua o ka mānoanoa o ka pā i ʻae ʻia.
