Ka noi a me ka hoʻomohala ʻana o ka alumini alumini i ka ʻenehana moana

-Ke noi ʻana i ka paepae helicopter waho

Offshore aila wīwī anuu hoʻohana kila e like me ka mea nui structural mea, no ka lōʻihi-makahiki ike i ka Marine kaiapuni, oiai kila i ka ikaika kiʻekiʻe, ua alo me ka moʻo o nā pilikia e like me ka corrosion, pōkole lawelawe ola.He ʻāpana koʻikoʻi ʻo Helideck o ka hoʻomohala ʻana i ka ʻaila a me ke kinoea.Hoʻohana ʻia ia no ka lawe ʻana a me ka pae ʻana o nā helikopa a he loulou koʻikoʻi e mālama i ka pilina me ka ʻāina.Ma muli o ka nui o kona leo, pono e loaʻa iā ia nā koi o kona paona, ʻoʻoleʻa a me nā mea ʻē aʻe.Hoʻohana nui ʻia ka module helicopter deck alumini ma muli o kona kaumaha māmā, ikaika maikaʻi a ʻoʻoleʻa.

Aia ke kahua helicopter alumini alumini i ka papa lalo a me kahi poloka deck i hoʻopaʻa ʻia ma ka ʻaoʻao lalo i hana ʻia me nā profiles alloy alumini i hoʻopili pū ʻia.Ua like ka ʻāpana o nā profiles me ka huaʻōlelo "工", a ua hoʻonohonoho ʻia kahi lua pā paʻakikī ma waena o nā papa luna a lalo.Hoʻohana ʻia ke kumu mechanical a me ka ikaika kulou o nā profile alloy alumini e hoʻokō i nā koi o ka hana a hōʻemi i ke kaumaha make.Eia kekahi, i loko o ke kai moana, he mea maʻalahi ka mālamaʻana i ka paepae helicopter alumini, maikaʻi ke kū'ē i ka corrosion;E hoʻohana i ka mode splicing profile, e pale i ka welding, ʻaʻohe welding wela wela, hiki ke hoʻolōʻihi i ke ola lawelawe, pale i ka hemahema.

-Ka noi ma nā moku ukana LNG (liquefied natural gas).

Me ka hoʻomau mau ʻana o ka ʻaila aila a me nā kumuwaiwai o waho, ʻo nā wahi hoʻolako kinoea kūlohelohe nui a me nā wahi koi o ka honua kahi mamao loa mai kekahi i kekahi, i hoʻokaʻawale pinepine ʻia e nā moana.No laila, ʻo ka hoʻouna ʻana i ka moana ka lawe nui ʻana o ke kinoea maoli LIQUEFIED i kēia manawa.I ka hoʻolālā ʻana o ka pahu mālama moku LNG, pono ka metala me ka hana haʻahaʻa haʻahaʻa maikaʻi a me kekahi ikaika a paʻakikī.ʻOi aku ka ikaika o ka mea alumini alumini ma ka wela haʻahaʻa ma mua o ka wela o ka lumi, a he māmā ke alumini alumini i ke kaumaha a pale i ka corrosion i loko o ke ea moana, ʻo ia ka mea kūpono no ka hoʻohana ʻana i ka wela haʻahaʻa.

Hoʻohana nui ʻia ka 5083 alumini alumini i ka hana ʻana i nā moku LNG a me nā pahu mālama LNG.ʻO ka mea nui, ʻo Iapana, ka mea lawe nui loa o LNG, i kūkulu i kahi ʻano o nā pahu mālama LNG a me nā moku lawe mai nā 1950s a me 1960s, ma waena o ia mea aia kahi pahu waihona LNG me ka pā nui o ka 5083 alumini alumini.ʻO ka hapa nui o nā alumini alumini he mau mea koʻikoʻi no ka hoʻolālā tank top ma muli o ko lākou kaumaha māmā a me ka pale ʻana i ka corrosion.I kēia manawa, he liʻiliʻi wale nō nā ʻoihana i ka honua e hiki ke hana i nā mea alumini haʻahaʻa haʻahaʻa no nā pahu mālama LNG.5083 alumini alumini 160mm pā mānoanoa ʻē aʻe i hoʻomohala ʻia e Iapana he haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa a me ke kūpaʻa luhi.

-Pono ma ka uapo moana

Hana ʻia nā mea hana dock moana e like me ke alahao, ke alahaka lana a me ke alahele me 6005A a i ʻole 6060 alumini alloy welded, ua hana ʻia ka pahu lana me ka 5754 alumini alloy welded watertight tank body, ʻaʻole pono ke pena ʻia a i ʻole ka lāʻau lana ʻana.

-Alunium alloy drill paipu

ʻO ka paipu alumini alumini puʻupuʻu i nā waiwai o ka haʻahaʻa haʻahaʻa, ke kaumaha māmā, ka ikaika kikoʻī kiʻekiʻe, ka torque rotary liʻiliʻi e koi ʻia, ke kūpaʻa hopena ikaika, ke kūpaʻa corrosion maikaʻi, a me ke kūʻē liʻiliʻi liʻiliʻi ma waena o ka pā puka.I ka hihia o kekahi mana wili, hiki i ka hoʻohana ʻana i ka alumini alloy drill pipe hiki ke hōʻea i ka hohonu hohonu i hiki ʻole ke hoʻokō ʻia ka paipu drill kila.I kēia manawa, ua hoʻohana maikaʻi ʻia ka paipa drill alumini alumini i ka ʻimi ʻaila.Mai ka makahiki 1960, ua hoʻohana nui ʻia ka paipa drill alumini alumini ma ka Soviet Union.I ka Soviet Union, ua hoʻohana ʻia ka paipa alumini alumini e wili ai i ka 70% a i ka 75% o ka nui o nā kiʻi.I loko o ke kahua hoʻoheheʻe ʻana i waho, i hui pū ʻia me nā mea maikaʻi o ka pale ʻana i ka corrosion alloy alumini, kiʻekiʻe kiʻekiʻe alumini alumini drill paipu i loaʻa ka manaʻo noi nui i ka ʻenehana waho.
