ʻO ke kila kila maʻemaʻe ʻole no ka lawe ʻana i ka wai
1. 321 paipu kila kuhiliʻole.Hoʻohana ʻia ka paipu kila maʻemaʻe (GB14976-2002) no ka hana ʻana i nā paipu mokumahu wela, nā paipu wai paila a me nā paipu mokumahu locomotive boiler, nā paipu uahi nui, nā paipu uwahi liʻiliʻi a me nā paipu pōhaku lepo o nā hale like ʻole.ʻO ke kila hoʻoheheʻe kalapona i ʻōwili ʻia a me nā paipu kila maʻemaʻe.
2. 321 mau paipu kila kuhiliʻole: kiʻekiʻe kiʻekiʻe kalapona structural kila, hoʻohuihui kila a me kuhiliʻole wela-pale kila seamless kila paipu maʻamau i hoʻohana 'ia no ka hana kiʻekiʻe-pressure a ma luna o ka mahu boiler paipu.Aia kēia mau paipu paila ma lalo o ka wela kiʻekiʻe a me ke kaomi kiʻekiʻe.E hana pū ʻia nā hana a me nā paipu i ka oxidation a me ka corrosion ma lalo o ka hana o ke kinoea flue wela a me ka mahu wai.No laila, koi ʻia nā paipu kila e loaʻa ka ikaika paʻa kiʻekiʻe, ke kūpaʻa kiʻekiʻe o ka oxidation, a me ka paʻa o ka hoʻonohonoho.ʻO nā paipu hydraulic prop.
3. ʻO nā māka kila i hoʻohana ʻia no nā paipu kila kila 321: 304 321 316 317 310, etc.
4. Alloy structural steel pipe kila māka 15MoG, 20MoG, 12CrMoG, 15CrMoG, 12Cr2MoG, 12CrMoVG, 12Cr3MoVSiTiB, etc.;aia nā mea kila kila kila i hoʻohana mau ʻia ʻo 1Cr18Ni9, 1Cr18Ni11Nb kiʻekiʻe-pressure boiler tubes, ma waho aʻe o ka hōʻoia ʻana i ka haku melemele a me nā waiwai mechanical, pono e hana ʻia ke kaomi wai i kēlā me kēia.No ka ho'āʻo, pono e hana i kahi ho'āʻo flaring a flattening.
5. Hāʻawi ʻia nā paipu kila kila 321 ma ke kūlana wela.Eia kekahi, aia kekahi mau koi no ka microstructure, ka nui o ka palaoa, a me ka papa decarburized o ka paipu kila i hoʻopau ʻia.ʻO nā paipu kila maʻemaʻe no ka hoʻoheheʻe honua a me ka hoʻomalu ʻana i ka ʻaila;e hoʻohana i nā rig wili e wili i nā luawai no ka ʻimi ʻana i ka hale pōhaku lalo, ka wai lepo, ka ʻaila, ke kinoea maoli a me nā kumu waiwai mineral.ʻOi aku ka hiki ʻole ke hoʻokaʻawale ʻia ka ʻimi ʻaila a me ke kinoea maoli mai ka wili luawai.ʻO nā paipu kila maʻemaʻe no ka hoʻoheheʻe ʻana i ka honua a me ka hoʻomalu ʻana ʻo ia ka mea nui no ka wili ʻana, me nā paipu o waho o waho, nā paipu o loko, nā pahu, a me nā paipu drill.No ka mea, pono e hohonu ka paipu wiliwili i loko o ka hohonu o ka hoʻokumu ʻana o kekahi mau kilomita e hana, 1cr5mo alloy pipe.
6. He paʻakikī loa nā kūlana hana.Hoʻopili ʻia ka paipu drill i nā koʻikoʻi e like me ke ʻano o ka ʻāʻī ʻana, ka hoʻopaʻa ʻana, ke kuʻi ʻana, ka torsion, a me ka hoʻouka ʻana i ka hopena like ʻole, a me ka lepo a me ka lole pōhaku.No laila, pono e lawa ka ikaika o ka paipu, ka pa'akikī, ka pale a me ka Impact toughness, ka paipu kila i ho'ohana 'ia "DZ" (Geological Pinyin prefix) a me ka helu hoʻokahi e hōʻike i ka helu o ke kila.DZ50 40Mn2, 40Mn2Si;DZ55 40Mn2Mo, 40MnVB;40MnMoB o DZ60, 27MnMoVB o DZ65.Hāʻawiʻia nā paipu kila ma kahi kūlana wela.
7. Na paipu poha aila: na paipu hili ole no na paipu umu ahi, na paipu hoololi wela a me na paipu i hoohana ia ma na hale hana aila.Hoʻohana mau ʻia ke kila kalapona kiʻekiʻe kiʻekiʻe (10, 20), ke kila kila (12CrMo, 15CrMo), ke kila pale wela (12Cr2Mo, 15Cr5Mo), ke kila kila (1Cr18Ni9, 1Cr18Ni9Ti) hana.
8. Hoʻohana ʻia nā paipu kila maʻemaʻe no 321 mau paipu kuhili ʻole (GB3087-1999) no ka hana ʻana i nā paipu mokumahu wela, nā paipu wai paila a me nā paipu locomotive boiler, nā paipu uahi nui, nā paipu uwahi liʻiliʻi a me nā paipu pōhaku lepo no nā hale like ʻole nā paila kaomi waena.Kiʻekiʻe kiʻekiʻe kalapona structural kila pumehana a me ke anu (rolled) seamless kila paipu.321 paipu kila kila: Hoʻohana nui ʻia ia no ka hana ʻana i ke kila kila kalapona kiʻekiʻe, ke kila kila kila a me ke kila wela ʻole a me nā paipu kila maʻemaʻe no nā paipu paila mahu o ke kiʻekiʻe a ma luna.Ke hana nei kēia mau paipu boiler ma lalo o ka wela kiʻekiʻe a me ke kaomi kiʻekiʻe., E oxidized a corroded ka paipu ma lalo o ka hana o ke kinoea flue wela wela a me ka mahu wai.No laila, koi ʻia ka paipu kila e loaʻa ka ikaika hoʻomau kiʻekiʻe, kiʻekiʻe oxidation kū'ē, a me ka paʻa hui maikaʻi, hydraulic prop paipu.
9. Hāʻawi ʻia nā paipu kila kila 321 ma ke ʻano wela.Eia kekahi, aia kekahi mau koi no ka microstructure, ka nui o ka palaoa, a me ka papa decarburized o ka paipu kila i hoʻopau ʻia.ʻO nā paipu kila maʻemaʻe no ka hoʻoheheʻe honua a me ka hoʻomalu ʻana i ka ʻaila;e hoʻohana i nā rig wili e wili i nā luawai no ka ʻimi ʻana i ka hale pōhaku lalo, ka wai lepo, ka ʻaila, ke kinoea maoli a me nā kumu waiwai mineral.
