Ka mea hana a me ka mea hoʻolako o ASME SA 789 UNS S32205 i hoʻopili ʻia ʻo Tubing, ka mānoanoa pā maʻamau i ʻīniha/mm

ʻO Duplex 2205 Tube he paipu kila kila.Aia ia i ka ʻohana o nā kila kila i kapa ʻia ʻo nā kila duplex.Aia nā hui like ʻole o kēia mea.Hiki ke hana ʻia nā paipu o kēia ʻohana ma ke kiʻi anu ʻana o ka ʻōwili wela a me ka wili.Ua huki anu ʻia ka Alloy 2205 Seamless Tube a ʻoi aku ka liʻiliʻi o ka ʻawaʻawa.ʻOi aku ka ikaika o nā mea ʻole ma mua o ka Duplex SS 2205 Welded Tubing akā pololei loa i ka nui.Pono ka pololei o ke ana i nā noi koʻikoʻi e koi ana i ka pololei i nā ana a me nā helu.ʻO ka mea kūikawā o Duplex 2205 Seamless Tube he ʻano ʻelua.ʻAʻole ia he ferritic a ʻaʻole austenitic akā aia nā mea maikaʻi loa o nā ʻāpana ʻelua.ʻO ka Duplex 2205 Tube kahi puʻupuʻu super duplex grade a loaʻa iā ia nā ʻāpana kila ferritic a me austenitic i kona ʻano.No laila ua hoʻomaikaʻi ʻia ka ikaika a me nā waiwai kū'ē i ka corrosion.Hiki ke hoʻohana ʻia ka Duplex 2205 Seamless Tube i nā noi e like me ka noi kai a me lalo o ka wai i ʻike ʻia i nā kaiapuni waiwai chloride ion.

ʻOi aku ka ikaika o ka ASTM A790 Duplex 2205 Welded Tube a loaʻa nō hoʻi nā waiwai kūʻē i ka corrosion.He ʻoi aku ka ikaika ma mua o nā paipu seamless.Pono nā noi 2205 Duplex Tube i nā ʻano like ʻole, ka nui a me nā papa kaomi o nā paipu.Hoʻohana ʻia ka SA 789 Alloy 2205 4 inch Tube i ka hoʻololi ʻana o ka wai.Aia nā nui ʻē aʻe mai ka ½" a hiki i ka 42" a ʻoi aku.Ma muli o nā koi noi, hana ʻia nā paipu i kekahi manawa.Hoʻohana ʻia kēia mau mea i ka petrochemical, kemika, ka hoʻoili ʻana i ka meaʻai, ka pulp a me ka pepa, ka aila a me ke kinoea a me nā ʻoihana hoʻoulu ʻana i ka waikawa organik pū kekahi.Hiki i ka Duplex SS 2205 Schedule 40 Tube ke kū i ke kaomi kiʻekiʻe a hoʻohana ʻia i nā condensers a me nā mea hoʻololi wela.

Liaocheng Sihe SS Material Co., Ltd.he mau mea hoolako paipu kila kuhilihi.Ke hana ʻia nei ia e ka waiwai maka kiʻekiʻe me ke alakaʻi ʻana o ka hui maikaʻi loa.Loaʻa ia ma nā ʻano nui, nā māka a me nā kikoʻī.

ʻO nā paipu Duplex 2205 ka mea i hoʻohana nui ʻia i ka papa kila stainless steel duplex.ʻO ia ka nitrogen i hoʻonui ʻia i ka duplex stainless steel i hoʻololi ʻia e kūʻē i nā pilikia corrosion maʻamau i ʻike ʻia me nā ʻano kila kila 300.

ʻO 2205 duplex nā paipu kila kila he ʻelua-phase, ferritic, austenitic 22% chromium, 3% molybdenum a me 5 - 6% nickel alloyed stainless steel.

ʻO ka paipu kila duplex i hōʻike ʻia e ka ikaika hua kiʻekiʻe, pāpālua i nā māka maʻamau austenitic stainless steel.Hōʻike pū ʻo ia i ka ikaika luhi maikaʻi, a me ke kūʻē kūʻē ʻana i ke koʻikoʻi o ka corrosion cracking, pitting, crevice, erosion, a me ka corrosion maʻamau i nā kaiapuni koʻikoʻi.

ʻO nā paipu kila duplex e hōʻike ana i nā waiwai kūpaʻa ʻoi aku ka maikaʻi i ka Stainless Steel 316 a me 316L i ka nui o nā kaiapuni.Loaʻa ia i ka chromium, nitrogen a me ka molybdenum a hāʻawi pū kekahi i ka pitting kiʻekiʻe a me ka crevice corrosion kū'ē, ʻoiai i ka oxidizing a me ka acidic solutions.

ʻAʻole kūpaʻa ka paipu kila kila duplex i ka chloride stress corrosion māwae a me nā mahana a hiki i 302°F.Ma nā wahi caustic hāʻawi ia i ka hana maikaʻi ma muli o ke alo o ka ferrite.

ʻO ka duplex 2205 paipu liʻiliʻi he maikaʻi ke kūpaʻa oxidation i nā wela kiʻekiʻe.Loaʻa iā ia ka weldability maikaʻi a ʻaʻole pono e wili ʻia me ka ʻole o ka metala hoʻopiha no ka mea hiki ke hopena i ka ferrite kiʻekiʻe.Aia kona pae wela ma waena o 1868 – 2012°F.

ʻO ka wela wela kiʻekiʻe loa o nā paipu hoʻololi wela kila kila ma waena o nā pae o 2010 – 2100°F.ʻOi aku ka paʻakikī o ka mīkini ma mua o ka austenitic stainless steels 300 series.
