Duplex 2205 VS 316 kila kila

He mea maʻamau ka 316 stainless steel, hoʻohana nui ʻia i ka petrochemical, nā mea kanu mea kanu, ka hana moku a me nā ʻoihana ʻē aʻe. ʻO ka hoʻohana ʻana i ke kila duplex 2205 e hoʻonui nui ʻia, ʻoi aku ka nui o ka aila o waho, ka desalination o ke kai a me nā māla ʻē aʻe me nā koi corrosion kiʻekiʻe. E hoʻohana paha316 paipu kila kilaa i ʻole ka paipu duplex kahi pilikia e hālāwai pinepine ai kā mākou mea kūʻai. Hōʻike pōkole kēia ʻatikala i nā ʻokoʻa ma waena o duplex 2205 a me 316 kila kila. Manaʻo wau e kōkua ia iā ʻoe.

Ka ʻokoʻa kemika ma waenaDuplex 2205a me 316 SS

Hoʻohana nui ʻia ʻo 316 stainless steel i ka ʻoihana kemika ma muli o kona kūpaʻa maikaʻi loa. Loaʻa iā 2-3% molybdenum element, a no ka derivative o 18-8 austenitic stainless steel. ʻO Duplex 2205, ua hoʻohui ʻia me ka nitrogen e hoʻomaikaʻi ai i kona kūʻē ʻana i ka corrosion. A ʻo ka ʻiʻo hoʻonā paʻa i loko o ka ferrite a me ka austenite ua noho i kēlā me kēia hapalua, ma ka liʻiliʻi o hoʻokahi o lākou e hiki i 30%, e hana ai i nā ʻano o ka ferrite a me ka austenitic stainless steel.

Nā ʻokoʻa ma waena o Duplex 2205 a me 316 Stainless Steel

• a) ʻO ka ikaika hua o ka duplex 2205 he hoʻokahi manawa kiʻekiʻe ma mua o 316L, a ua lawa ka paʻakikī paʻakikī no ka hana ʻana. A ʻo ka mānoanoa o ka pā o ka ipu kaomi i hana ʻia i ka duplex 2205 he 30-50% ka lahilahi ma mua o ka 316L, hiki ke mālama i ke kumukūʻai.

• b) Hana maikaʻi loa ʻo Duplex 2205 i ka pale ʻana i ka corrosion koʻikoʻi, ʻoi loa ke hoʻohana ʻia i loko o ke kai i loko o nā ion chloride. Eia nō naʻe, ʻo ke koʻikoʻi koʻikoʻi kahi pilikia koʻikoʻi e hoʻoponopono ai no ka austenitic stainless steel me 316L.

• c) Hana ʻo Duplex 2205 i kahi kūpaʻa ʻoi aku ka maikaʻi ma mua o 316L i hana ʻia ma nā ʻano mea like ʻole. Ke hana nei ia i ke kū'ēʻino kiʻekiʻe loa ma ka acetic acid, formic acid, a hiki ke lilo i mea pani o austenitic stainless steel, a me ka corrosion resistant alloy. Eia nō naʻe, no ke koho ʻana i ka duplex 2205 a i ʻole 316L, ua hoʻoholo ʻia e nā pono kūlohelohe a me ke kumukūʻai.

• d) Loaʻa i ka Duplex 2205 ka ikaika kiʻekiʻe a me ke kūpaʻa ʻana o ka corrosion kūloko, ʻaʻahu i ke kūpaʻa corrosion a me ka hana luhi corrosion, ʻoi aku ka maikaʻi ma mua o 316L stainless steel.

• e) He haʻahaʻa ka helu hoʻonui laina o duplex 2205 ma mua o 316L, a kokoke ia i ke kila kalapona. ʻO kēia ka mea i kūpono i ka duplex 2205 no ka hoʻopili kila kalapona, e lawe mai ana i kahi mea nui no ka ʻenekinia.

• f) ʻAʻohe mea ma lalo o nā kūlana hoʻoikaika a paʻa paha, ʻo ka duplex 2205 ka ʻoi aku ka nui o ka ikehu absorption ma mua o 316L, e lawe mai i nā pono kūpono a me nā waiwai noi kūpono no nā ʻāpana hana a i ʻole nā ​​paipu i ka wā e pili ana i nā pilikia e like me ka hopena, pahū.

ʻO nā hemahema o Duplex 2205

Me ka nui o nā pōmaikaʻi, ʻoi aku ka maikaʻi o ka duplex 2205 ma mua o 316. Eia naʻe, ke hoʻohālikelike ʻia me 316, loaʻa i ka duplex 2205 nā hemahema:

• a) ʻAʻole like ka hoʻohana ʻana o duplex 2205 i ke ao holoʻokoʻa a i ʻole like ʻole e like me 316L. No ka laʻana, inā makemake kekahi e hana ma lalo o ka mahana ma lalo o 250 degere no ka manawa lōʻihi, a laila hiki i ka 316L stainless steel ke mākaukau.

• b) ʻOi aku ka maikaʻi o ka paʻakikī o ka duplex 2205 ma mua o 316L, a ʻoi aku ka maikaʻi o ka hana ʻana i ke anuanu.

• c) ʻO Duplex 2205 ka haʻahaʻa haʻahaʻa haʻahaʻa, a ʻo ka mālama ʻana i ka wela a me ke kaʻina hana kuʻi ʻana pono e hoʻopaʻa pono ʻia, i pale aku ai i ka manawa pōʻino e kū mai, e hōʻino ai.

• d) Ke hoʻohālikelike ʻia me ka austenitic stainless steel, ʻo ka nāwaliwali o ka duplex stainless steel ʻo ia ka nui o nā kiko ferrite.

Duplex 2205 VS 316 SS Kumukuai

Manaʻo paha kekahi poʻe he kiʻekiʻe loa ke kumukūʻai o ke kila duplex, ʻoi aku ka kiʻekiʻe ma mua o 316 stainless steel. ʻOiaʻiʻo, pili ia i ka huahana.

Hāʻawi mākou i nā paipu duplex 2205 a me 316 SS a me nā mea pono, e ʻoluʻolu e hoʻokaʻaʻike mai iā mākou inā he mau koi.
