1. Ke kūpaʻa maikaʻi loa i ka palaho ma nā wahi kai

ʻO kekahi o nā pilikia nui i nā ʻōnaehana moana a me wahoka palaho i hoʻoulu ʻia e ka chloridei hoʻokumu ʻia e ka wai kai. Hiki ke pilikia nā kila kila maʻamau e like me 316Lka pala o ka lua a me ka ʻōpala crevicei ia mau kūlana, e alakaʻi ana i ka hāʻule ʻana o nā lako a me nā hoʻoponopono pipiʻi.

2205 Kaula uea kila kila Duplexakā naʻe, hāʻawi ʻia:

• Ke kūpaʻa kiʻekiʻe i ka pitting a me ka crevice corrosionma muli o kona 22% chromium a me 3% molybdenum.

• ʻO ke kūpaʻa maikaʻi loa i ka haki ʻana o ka chloride stress corrosion (SCC), he ʻano hāʻule maʻamau ia i nā pae austenitic ma lalo o ke kaomi i loko o ka wai kai.

• Ola lōʻihima nā kūlana wai i lalo o ka wai, ke kai eʻe, a me nā wahi pīpī.

ʻO kēia ka mea e kūpono loa ai nonā kaula hoʻopaʻa, nā winches, nā cranes, nā davits waʻa hoʻopakele, a me nā kaula heleumai hōʻike ʻia i ka wai paʻakai a me ka haumākū.

2. Ka ikaika mīkini kūikawā a me ka hiki ke hāpai i ka ukana

Hāʻawi ka ʻōnaehana duplex o 2205kokoke i ka pālua o ka ikaika huao nā kila kila maʻamau 304L a me 316L.

Nā Pōmaikaʻi Koʻikoʻi:

• Kiʻekiʻe aʻeikaika luhi, e hiki ai ke lōʻihi ke ola lawelawe ma lalo o ka hoʻouka cyclic.

• ʻOi aku ka maikaʻike kūpaʻa hopena, ʻoiai ma nā mahana haʻahaʻa loa.

• ʻOi aku ka maikaʻiikaika tensileno ka lawelawe ʻana i nā ukana kaumaha ma nā ʻōnaehana hāpai a me nā rigging ma waho.

ʻO kēia ikaika kiʻekiʻe e hiki ai i nā mea hoʻolālā kee hoʻemi i ke anawaena o ke kaula ueaʻoiai e mālama ana i ka hiki ke ukana - e mālama ana i ke kaumaha a hoʻomaikaʻi i ka pono o ka ʻōnaehana, ʻoiai he mea nui nonā crane moana, nā kaula ROV, a me nā hana winching.

3. Ke kū'ē ʻana i ka haki ʻana o ka palaho kaumaha (SCC)

I nā wahi kai wela a waiwai i ka chloride, he mea maʻalahi nā kila kila kuʻuna ika haki ʻana o ka palaho koʻikoʻi, kahi e hiki ai ke alakaʻi i ka hāʻule koke a me ka pōʻino.

2205 Kaula uea kila kila Duplexhōʻike i ke kū'ē koʻikoʻi i ka SCC, mahalo i kona kaulike ferritic-austenitic:

• Pale ka pae ferrite i ka hoʻouka ʻana o ka ion chloride ma lalo o ke kaomi.

• Mālama ka pae austenite i ka maʻalahi a me ka ductility.

Hoʻopaʻa kēia waiwai i ka hilinaʻi kūkulu lōʻihi i nā ʻāpana e like menā laina hoʻopaʻa, nā pale palekana, a me nā kaula hoʻoluhi kahua— kahi hiki ʻole ke hoʻoweliweli ʻia ka palekana.

4. Hana luhi maikaʻi loa ma lalo o nā ukana hoʻoikaika

ʻO nā hana ma waho a me ke kai e pili ana i ka neʻe mau ʻana, ka haʻalulu, a me ka hoʻouka cyclic i hoʻokumu ʻia e nā nalu, ka makani, a me nā mīkini. Ma lalo o kēia mau kūlana,ke kūpaʻa luhihe mea koʻikoʻi.

Hōʻike ke kaula uea Duplex 2205 i ka ʻoi aku ka maikaʻiluhi hoʻomanawanui, e hiki ai iā ia ke mālama i ka pono ma hope o nā miliona o nā pōʻaiapuni ukana.

Hoʻokomo pū ʻia nā noi maʻamau:

• Nā ʻōnaehana hoʻonohonoho hoʻololi

• Nā crane moana a me nā lako hāpai

• Nā kaula hoʻopaʻa a me ke kauō ʻana

• Nā kaula hāpai ʻaila ma waho o ke kai

ʻO kona ʻano microstructure kū hoʻokahi e pale aku i ka laha ʻana o nā māwae, e hōʻoiaʻiʻo ana i ka hana palekana a paʻa hoʻi ma lalo o nā ukana e loli mau ana.

5. Ke kū'ē kūikawā i ka ʻino a me ka ʻaʻahu

Ma nā wahi kai, hiki i ka ʻaʻahu mechanical a me ka ʻinoʻino mai ke one, ka wai kai, a me nā ʻāpana i hoʻokuʻu ʻia ke hōʻino i nā kaula uea kila maʻamau.

Hāʻawi ʻo 2205 Duplex:

• Kiʻekiʻepaʻakikī o ka ʻilie pale aku i ka ʻānai ʻia.

• Haʻahaʻa ka nui o ke komo ʻana ma lalo o ka friction.

• Ke kū'ē ika ʻinoʻino-ka palaho, kahi e hui pū ai ka ʻaʻahu mechanical me ka hoʻouka kemika.

ʻO kēia ka mea e makemake nui ai ke kaula uea Duplex nonā umbilicals subsea, nā kaula winch, a me nā ʻōnaehana trawli hōʻike ʻia i ke kaumaha mechanical kiʻekiʻe a me nā kūlana abrasive.

6. Hana maikaʻi loa i nā mahana sub-Zero

Hana pinepine nā noi ma waho o ke kai i nā aniau anuanu a i ʻole nā ​​​​​​wahi kai hohonu kahi e hiki ai i nā mahana ke hāʻule ma lalo o ka hau. Nui nā mea e nalowale ana i ka ductility i kēia mau mahana - akāMālama ke kaula uea kila kila Duplex 2205 i ka paʻakikī a me ka ikaika hopenaʻoiai ma –50°C.

Hoʻomaopopo kēia hiʻohiʻona i ka hoʻohana palekana i:

• Nā kahua kai ʻĀtika

• Nā kikowaena a me nā paipu LNG

• Nā moku kai anuanu

ʻO ke ʻano kaulike o ka metala e pale aku i ka haki palupalu, e hōʻoiaʻiʻo ana i ka hana hilinaʻi i ke anu nui.

7. Ka Pono o ke Kumukūʻai a me ka Lōʻihi o ke Ola

ʻOiai ʻoi aku ke kumukūʻai o ke kila kila Duplex ma mua o ke kila kalapona, hāʻawi ianā mālama kālā lōʻihima o kona kūpaʻa a me nā koi mālama i hoʻemi ʻia.

ʻO nā pōmaikaʻi o ke ola holoʻokoʻa:

• Hoʻolōʻihi ʻia ke ola lawelawe (a hiki i 2-3 manawa ma mua o 316L).

• Hoʻemi ʻia ke alapine (frequency) o ka hoʻololi a me ka downtime.

• ʻO ke kumukūʻai haʻahaʻa o ka loaʻa ʻana o nā pono hana koʻikoʻi.

No nā mea lawelawe moana a me nā mea lawelawe kai, unuhi kēia i nā pono hana koʻikoʻi a me nā pono hoʻomau.

8. Ka Hoʻomau a me nā Pōmaikaʻi Kaiapuni

ʻO ke kūpaʻa ʻana i ka pala a me ke ola lōʻihi o 2205 Duplex e hōʻemi ana i ka ʻōpala metala a hoʻemi i ka kapuaʻi kaiapuni o nā hana ma waho.

Nā Kumu Hoʻomau Hou Aʻe:

• 100% hana hou ʻia ma hope o ke ola lawelawe.

• ʻO ka hoʻohana ʻana i nā kumuwaiwai haʻahaʻa ma muli o ke ola lōʻihi.

• Hoʻemi ʻia ka pilikia o ka liki ʻana o ka aila a i ʻole nā ​​​​kemika mai nā uaea i ʻino ʻia.

sakysteel, me kona kūpaʻa i ka hana kila kila hoʻomau, e hōʻoiaʻiʻo ana ua hana ʻia nā kaula uea Duplex āpau e like meNā kūlana hoʻokele kaiapuni ISO 14001.
