He kuleana koʻikoʻi ko nā paipu alumini i nā ʻoihana like ʻole ma muli o ko lākou māmā, kūpaʻa i ka pala, a me ka laulā o nā noi. He loea ʻo Jindalai Steel Group Co., Ltd. i ka hana ʻana i nā ʻano paipu alumini like ʻole, me 1060 mau paipu alumini maʻemaʻe, 1100 mau paipu alumini, a me 2024 mau paipu alumini. He ākea nā noi o kā mākou huahana, e hōʻoiaʻiʻo ana e loaʻa i nā mea kūʻai aku nā mea hana kiʻekiʻe e hoʻokō i kā lākou mau pono kikoʻī.

Nā kikoʻī o ka paipu alumini

Loaʻa nā paipu alumini i nā ʻano a me nā kikoʻī like ʻole, i hoʻolālā ʻia no nā noi kikoʻī. No ka laʻana, ua kaulana ka paipu alumini 6061 no kona mechanical a me ka weldability maikaʻi loa, e kūpono ana no nā noi kūkulu. I kēia manawa, ʻo ka paipu alumini 6063, ma muli o kona ʻano nani a me ke kūpaʻa maikaʻi i ka palaho, hoʻohana pinepine ʻia i ka ʻoihana kūkulu.

No nā noi e koi ana i ka ikaika kiʻekiʻe, ʻo ka paipu alumini aerospace 7075 ke koho makemake nui ʻia, ʻoi aku hoʻi ma ke kahua aerospace. Hāʻawi kēia paipu alumini paʻakikī i kahi lakio ikaika-a-kaumaha maikaʻi loa, e kūpono ai no nā ʻāpana mokulele. Eia kekahi, ʻo kā mākou paipu alumini kūpaʻa i ka popo 5052 a me nā paipu alumini 5083 he kūpono no nā noi moana, e hāʻawi ana i ke kūpaʻa maikaʻi loa i ka pala o ka wai kai.

ʻO ka paipu kila alumini-manganese 3003 kekahi koho ʻē aʻe, i ʻike ʻia no kona hana maikaʻi a me ka ikaika kūpono, kūpono no nā ʻano hana like ʻole e like me nā pahu mālama a me nā ipu kaomi. No nā noi maʻemaʻe kiʻekiʻe, hōʻoia kā mākou paipu alumini maʻemaʻe kiʻekiʻe i ka haumia liʻiliʻi, e kūpono ana no nā ʻoihana lāʻau lapaʻau a me nā meaʻai.

  Kaʻina Hana Kuʻi ʻana o ka Tube Aluminum

Pono nā ʻano hana kikoʻī no ka hoʻopili ʻana i nā paipu alumini e hōʻoia i nā wili ikaika a paʻa. ʻO nā kaʻina hana wili i hoʻohana pinepine ʻia e komo pū me ka wili ʻana o ke kinoea tungsten inert (TIG) a me ka wili ʻana o ke kinoea inert metala (MIG). Makemake ʻia ka wili ʻana o TIG no kona pololei kiʻekiʻe a me ka maikaʻi o ka wili ʻana, a kūpono loa ia no nā mea lahilahi, e like me nā paipu alumini maʻemaʻe 1060. ʻO ka wili ʻana o MIG, ma ka ʻaoʻao ʻē aʻe, ʻoi aku ka kūpono no nā ʻāpana mānoanoa a hoʻohana nui ʻia i nā noi ʻoihana.

I ke kuʻi ʻana i nā paipu alumini, pono e noʻonoʻo pono ʻia nā waiwai o ka metala. No ka laʻana, ʻo nā paipu alumini 2024, i ʻike ʻia no ko lākou ikaika kiʻekiʻe, pono paha e hoʻomehana mua ʻia e hoʻokō i ka maikaʻi o ka weld. Eia kekahi, he mea nui ka hoʻomaʻemaʻe pono ʻana a me ka mālama ʻana i ka ʻili o ka paipu e pale ai i ka haumia a hōʻoia i kahi weld ikaika.

Nā hiʻohiʻona noi o nā paipu alumini

He nui nā noi o nā paipu alumini ma nā ʻoihana like ʻole. Ma ke kahua aerospace, hoʻohana ʻia nā paipu alumini alloy aerospace-grade, e like me nā papa 7075 a me 2024, i nā hale mokulele a me nā ʻāpana ma muli o kona māmā a me nā waiwai ikaika kiʻekiʻe.

I loko o ka ʻoihana kaʻa, hoʻohana nui ʻia nā paipu alumini i nā laina wahie, nā mea hoʻololi wela, a me nā ʻāpana kūkulu ma muli o kona kūpaʻa i ka pala a me nā pono māmā. I waena o lākou, kaulana loa nā paipu alumini 5052 kū i ka pala ma kēia kahua ma muli o kona kūpaʻa a me ka hilinaʻi.

Hāʻawi pū nā paipu alumini i nā pono koʻikoʻi i nā noi moana, me ka paipu alumini 5083 ka mea makemake ʻia no nā ʻili a me nā ʻāpana ʻē aʻe i hōʻike ʻia i nā ʻano kai ʻino. Eia kekahi, ʻo ka paipu alumini 8011, ma muli o kona mau waiwai pale maikaʻi loa, hoʻohana pinepine ʻia i nā ʻoihana hoʻopili a me ka hana ʻana i ka meaʻai.

I ka hōʻuluʻulu manaʻo, hāʻawi ʻo Jindalai Steel Group Co., Ltd. i kahi laulā piha o nā huahana paipu alumini, me nā paipu alumini maʻemaʻe 1060, nā paipu alumini 1100, a me nā paipu alumini pale ʻino like ʻole. Kūpaʻa mākou i ka maikaʻi a me ka hana hou, e hōʻoia ana e loaʻa i kā mākou mea kūʻai aku nā huahana i kūpono loa i kā lākou mau noi kikoʻī. Inā makemake ʻoe i nā paipu alumini maʻemaʻe kiʻekiʻe a i ʻole nā ​​​​paipu alumini alloy aerospace-grade, loaʻa iā mākou ka ʻike a me nā kumuwaiwai e hoʻokō ai i kāu mau pono. E aʻo hou e pili ana i kā mākou huahana i kēia lā a loaʻa i ka hopena paipu alumini kūpono no kāu papahana.
