ʻO 316L paipu kila kila maoli me nā mea i hōʻoia ʻia
316 kuhiliʻole paipu mea he 'ano o hollow lōʻihi poepoe kila, i hoʻohana nui 'ia i loko o ka 'oihana pipelines transmission a me mechanical structural mea e like me ka aila, kemika 'oihana, lāʻau lapaʻau, meaʻai, kukui 'oihana, mīkini a me nā mea kani, etc. ua like ka kulou a me ka torsional ikaika, ua maʻalahi ke kaumaha, no laila ua hoʻohana nui ʻia i ka hana ʻana i nā ʻāpana mechanical a me nā hale ʻenekinia. Hoʻohana pinepine ʻia ia i ka hana ʻana i nā mea kaua maʻamau, barela, pūpū, a me nā mea ʻē aʻe: 316 paipu kila kila, 316 paipu ʻālohilohi, 316 paipu hoʻonaninani, 316 kila kila capillary, 316 kila kila welded paipu, 304 paipu kila kila.
ʻO ka nui o ka carbon carbon content o 1316l stainless steel pipe he 0.03, hiki ke hoʻohana ʻia i nā noi kahi hiki ʻole ke hoʻokō ʻia ka annealing ma hope o ke kuʻi ʻana a koi ʻia ke kūpaʻa corrosion kiʻekiʻe. ʻO 316 paipu kila kila ka nui o ka carbon content o 0.03 a hiki ke hoʻohana ʻia i nā noi kahi hiki ʻole ke hoʻokō ʻia ka annealing ma hope o ke kuʻi ʻana a koi ʻia ke kūpaʻa corrosion kiʻekiʻe.
316 a me 317 mau kila kuhiliʻole (e nānā i kēia no nā waiwai o 317 stainless steel) he molybdenum i loaʻa nā kila kila.
ʻOi aku ka maikaʻi o ka hana holoʻokoʻa o kēia kila ma mua o 310 a me 304 stainless steel. Ma lalo o ke kūlana wela kiʻekiʻe, i ka wā i emi iho ai ka nui o ka sulfuric acid ma mua o 15% a ʻoi aku ka kiʻekiʻe ma mua o 85%, 316 stainless steel ka nui o nā noi.
316 pā kila kila, i ʻike ʻia ʻo 00Cr17Ni14Mo2, kūpaʻa ʻino:
ʻOi aku ka maikaʻi o ka corrosion ma mua o 304 stainless steel a maikaʻi ke kūpaʻa corrosion i ka hana ʻana i ka pulp a me ka pepa.
ʻOi aku ka maikaʻi o ka carbide precipitation resistance o 316 stainless steel ma mua o ka 304 stainless steel, a hiki ke hoʻohana ʻia ka pae wela ma luna.
ʻO ka paipu kila kila ke ʻano o ke kila a puni ka lōʻihi, i hoʻohana nui ʻia i nā pipeline hoʻoili ʻoihana e like me ka petroleum, ka ʻoihana kemika, ka lāʻau lapaʻau, ka meaʻai, ka ʻoihana māmā, nā mea hana mechanical a me nā mea hana mechanical. Eia kekahi, i ka wā e like ai ke kulou a me ka ikaika torsional, māmā ke kaumaha, no laila hoʻohana nui ʻia i ka hana ʻana i nā ʻāpana mechanical a me nā hale ʻenekinia. Hoʻohana maʻamau ia i ka hana ʻana i nā mea kaua maʻamau, barela, pūpū, a me nā mea ʻē aʻe. Hiki ke hoʻokaʻawale ʻia kēia ʻano paipu kila i ke kila kila maʻemaʻe ʻole a me ke kila kila welded steel pipe (slotted pipe). Wahi a nā kaʻina hana ʻokoʻa, hiki ke hoʻokaʻawale ʻia i nā ʻano kumu: ʻōwili wela, extrusion, kiʻi anu a me ka ʻōwili anu. E like me ke ʻano o ka ʻāpana, hiki ke hoʻokaʻawale ʻia i ka paipu pōʻai a me ka paipu ʻano kūikawā. Hoʻohana nui ʻia ka paipu kila pōʻai, akā aia kekahi mau huinahā, rectangular, semicircular, hexagonal, equilateral triangle ʻO Octagonal a me nā paipu kila kila kila kūikawā.
E mālama ʻia ka hoʻāʻo hydraulic no ka paipu kila e lawe ana i ke kaomi wai e hoʻāʻo ai i kona kūpaʻa a me ka maikaʻi. Kūpono ia inā ʻaʻohe leakage, pulu a hoʻonui paha ma lalo o ke kaomi i kuhikuhi ʻia. E hoʻāʻo ʻia kekahi mau paipu kila i ka hoʻāʻo crimping, flaring test a flattening test e like me ke kūlana a i ʻole nā koi o ka mea noi.
304L paipu kila kuhiliʻole no ka honua kuhiliʻole kaha kaha ala. 304L paipu kila kila -- s30403 (AISI, ASTM)
ʻO ka hōʻailona Kina e pili ana me 304L ʻo 00Cr19Ni10
Nā hiʻohiʻona a me ka hoʻohana ʻana: ke kila me ka haʻahaʻa haʻahaʻa carbon ma mua o 0Cr19Ni9 i ʻoi aku ka maikaʻi o ke kūpaʻa intergranular corrosion. He mea ia me ka mālama ʻole ʻana i ka wela ma hope o ke kuʻi ʻana.
Ka helu a me ka hōʻike ʻana i ke kila
① Hoʻohana ʻia nā hōʻailona mea kemika honua a me nā hōʻailona aupuni e hōʻike i ka haku mele ʻana, a ua hoʻohana ʻia nā leka ʻAlapia e hōʻike i nā ʻano mea:
No ka laʻana: Kina, Rusia 12CrNi3A
②ʻO ke ʻano mākaʻikaʻi kila kuhiliʻole honua: hoʻohana i nā huahelu paʻa e hōʻike i ka moʻo kila a i ʻole nā helu; No ka laʻana, ʻo ʻAmelika Hui Pū ʻIa, Iapana, 300 series, 400 series a me 200 series; Hoʻohana ka American Iron and Steel Institute i ʻekolu huahelu e ʻike ai i nā māka maʻamau o ke kila kila malleable. Ma waena o lākou, hōʻike ʻia ke kila kila austenitic e nā helu o 200 a me 300 series, a ʻo ka ferritic a me ka martensitic stainless steel e hōʻike ʻia e nā helu o 400 series. ʻO ke kila kila, ka ua hoʻopaʻakikī paʻakikī a me ke kila kiʻekiʻe me ka mea hao ma lalo o 50% e hoʻohana pinepine i ka inoa patent a i ʻole ka inoa kālepa.
③ Hoʻokumu ʻia ka helu serial me nā leka Latin a me ke kauoha, e hōʻike wale ana i ke kumu.
Eia kekahi, ʻo ka 316 stainless steel ka mea kūʻē i ka moana a me ka ʻoihana hoʻoikaika kino. Loaʻa i ka 316 stainless steel ke kūpaʻa oxidation maikaʻi i ka hoʻohana intermittent me ka pale wela ma lalo o 1600 ℃ a me ka hoʻohana mau ʻana ma lalo o 700 ℃.
Ma ka laulā o 800-1575 degere, ʻoi aku ka maikaʻi ʻaʻole e hana mau i ka 316 stainless steel, akā ke hoʻohana mau ʻia ʻo 316 stainless steel ma waho o kēia pae wela, ʻoi aku ka maikaʻi o ke kila kila. ʻOi aku ka maikaʻi o ka carbide precipitation resistance o 316L stainless steel ma mua o ka 316 stainless steel, a hiki ke hoʻohana ʻia ka pae wela ma luna.
