Me ka nui opaipu kila humuhumunā mea kanu ma Kina, inā hiki iā ʻoe ke koho i kekahi mau ʻelele wale nō, ʻo wai ka mea mua e noʻonoʻo?

I kēia lā, e kūkākūkā kākou iā lākou pākahi, mai ka ʻākau a i ke kūkulu hema.

E hoʻomaka kākou me ka ʻĀkau Hikina o Kina. ʻO ka Hale Hana Paipu Kila Seamless ʻo Ansteel, i hoʻomaka ʻia i ka makahiki 1953, ʻo ia ka hale hana paipu kila seamless mua ma Kina Hou, i ʻike ʻia ma ka ʻoihana ʻo "cradle."

Loaʻa iā ia ka mana hana o 500,000 tons/makahiki, me nā kikoʻī mai Φ60-180mm, e hana nui ana i nā paipu luawai aila, nā paipu paipu, a me nā paipu paila.

Ua ʻike ʻia ʻo Ansteel e kona kahua paʻa a me ka ʻenehana paʻa, a ua loaʻa mau iā ia kahi inoa maikaʻi ma nā kahua hana petrochemical a me nā mīkini.

ʻO ka mea aʻe, e nānā kākou iā Kina ʻĀkau. ʻO ka Tianjin Steel Pipe, i ʻike ʻia ma ka ʻoihana ʻo "TPCO" (Great Seamless), he 3.5 miliona tons ka nui o ka hana makahiki, ʻoi aku ma mua o 1.5 miliona tons he mau paipu lua aila, e kau ana iā ia ma waena o ka papa kiʻekiʻe o ka mana hana hoʻokahi hale hana ma ka honua holoʻokoʻa.

Ke alakaʻi nei ia ma ka ʻāina holoʻokoʻa i nā huahana kiʻekiʻe e like me nā paipu paipu kai hohonu, nā paipu lua ʻaila hohonu loa, a me nā paipu lua ʻaila kūpaʻa kiʻekiʻe i ka pala.

I ka pōkole: ʻO Tianjin Steel Pipe ke koho mua no nā papahana kai hohonu a me nā luawai hohonu pae aupuni.

ʻO ka hui ʻo Baogang, aia ma ka ʻākau o Kina, e hoʻohana ana i nā kumuwaiwai honua laha ʻole o Baotou e loaʻa nā pono kūikawā i nā paipu kūikawā kūpaʻa i ka pala a me ka haʻahaʻa wela.

ʻOi aku ka nui o kāna hana hana makahiki ma mua o 1.2 miliona tone, me nā kikoʻī mai Φ38-457mm. I ka makahiki 2025, ua hana nui ʻia a hoʻolako ʻia kāna paipu kūkulu ikaika loa 690 MPa i hoʻomohala kūʻokoʻa ʻia.

Ua holomua wikiwiki ʻo Baogang i nā paipu kūkulu kiʻekiʻe a me nā paipu aila i nā makahiki i hala iho nei, a ua loaʻa iā ia ka palapala hōʻoia API.

Ma Kina Hikina, ua ʻoi aku ka hana ʻana o nā paipu kila humuhumu a Shandong Luli Group ma mua o 3.37 miliona tons i ka makahiki 2023, ʻo ia ka mea mua ma ka ʻāina ma ke ʻano o ka hana ʻana a me ka nui o ke kūʻai aku.

ʻO kāna hōʻailona lālā, ʻo 'Panjin Steel Pipe,' he ʻeono mau laina ʻōwili wela holomua me kahi mana i hoʻolālā ʻia he 6 miliona tone.

ʻO nā ʻano o Luli ka nui o nā ʻāpana, nā kikoʻī piha, a me ke kumukūʻai kiʻekiʻe, e kūpono ai no nā papahana nui.

Ma Kina Waena, ua hoʻokomo ʻo Henan Fengbao Pipe Industry i 1.2 biliona yuan i loko o kahi papahana paipu kila nui a kikoʻī loa, me kona hiki ke hana i nā paipu kila humuhumu wela e ʻoi aku ma mua o 2 miliona tone.

Ua hoʻopiha ʻo Fengbao i ka hakahaka i loko o kona hiki ke hana i nā paipu kila seamless nui, a ʻo kona hiki ke hana hohonu e helu ma luna o 60% o kāna hana holoʻokoʻa.

ʻO ka pahuhopu ke kūkulu i kahi kahua kiʻekiʻe no nā paipu aila, nā paipu kūkulu, a me nā paipu paila kaomi kiʻekiʻe a me ka waena.

Ma Kina Waena hoʻi, ua ʻike ʻia ʻo Hubei Daye Special Steel, i hoʻokumu ʻia i ka makahiki 1890, ʻo ia ke "wahi moe o ka hana kila Kina hou."

Loaʻa iā ia ka mana hana o hoʻokahi miliona tone o nā paipu kila humuhumu waena-mānoanoa kiʻekiʻe, me nā kikoʻī mai Φ51-534mm a me nā mānoanoa o ka paia mai 5-130mm.

Ua hoʻomalu lākou i ka mākeke no nā paipu mīkini ʻenekinia a me nā paipu paila kiʻekiʻe. No nā papahana me nā koi loea kiʻekiʻe, ʻo lākou ke koho kūpono.

Ua kūkākūkā mākou i kekahi mau ʻoihana ʻelele mai ka Hikina ʻĀkau, ʻĀkau, Hikina, a me Kina Waena. Ma ka ʻāpana aʻe, e hoʻomau mākou i ka hema e kamaʻilio e pili ana iā Baosteel a me nā hale hana nui ma lalo o CITIC Pacific ma Kina Hikina, a me kekahi mau ʻoihana me ka hana hoʻokuʻu ikaika. E hoʻomanaʻo e hahai mai iā mākou."

Ua kamaʻilio mākou e pili ana i kekahi mau mea hana nui ma nā ʻāpana ʻākau a me waena. I kēia manawa, ke neʻe nei mākou i Kina Hikina a me ka hema. ʻO kahi hui i kamaʻāina i nā mea a pau ʻo Baosteel, aia ma Shanghai.

Kina Hikina: ʻO Baosteel, ke "Kole Kolu" o nā Huahana Lōʻihi Kūlana Kiʻekiʻe

E hoʻomaka kākou me Baosteel. Aia ma Shanghai, he hale hana ikaika ia i hoʻokumu ʻia no ka manawa lōʻihi ma kā mākou ʻoihana. ʻO kāna wili wili hoʻomau 140-unit e haʻaheo nei i ka hana nui loa o ka honua o nā paipu kila seamless.

Hoʻohana nui ʻia nā paipu pae ikehu i nā kūlana hana paʻakikī e like me ke kai hohonu a me nā wahi honua hohonu, a ua komo kāna mau paipu lua wai ʻaila 13Cr e kūʻē i ka palaho i nā mākeke o waho.

I ka makahiki 2025, ua hoʻopukapuka ʻo Baosteel i 4.96 biliona yuan e kūkulu i kahi kumu paipu kila humuhumu kiʻekiʻe, e hoʻokiʻekiʻe ana i nā huahana lōʻihi kiʻekiʻe i kāna huahana hoʻolālā nui loa ʻekolu.

ʻIke ʻia ʻo Baosteel e nā hiki ʻenehana ikaika, ka hoʻomohala wikiwiki ʻana i nā huahana kiʻekiʻe, a me ka hoʻopukapuka R&D kiʻekiʻe mau i loko o ka ʻoihana."

E kamaʻilio kākou e pili ana iā CITIC Pacific Special Steel. ʻAʻole ia he hale hana hoʻokahi, akā he hui me ke keʻena nui ma Jiangyin, Jiangsu.

Loaʻa iā ia ʻelima mau kahua hana nui: ʻo Xingcheng Special Steel, Daye Special Steel, Qingdao Special Steel, Tianjin Steel Pipe, a me Jingjiang Special Steel.

I ka wā o ka Hoʻolālā ʻElima Makahiki 14, ua hoʻohui ʻo CITIC Special Steel i nā kumuwaiwai paipu kila o kona mau kumu like ʻole, e hoʻonui ana i kona hiki ke hana i nā paipu kila seamless i 5 miliona tons, e lilo ia i mea hana paipu kila seamless nui loa o ka honua.

I ka pōkole: ʻo ia ka hapalua o nā paipu kila i hoʻokuʻu ʻia aku e Kina.

Ma waena o nā lālā o CITIC Special Steel, ʻo Jiangyin Xingcheng Special Steel kona kahua hae, me ka hiki ke hana i kēlā me kēia makahiki he 6.9 miliona tone o ke kila kūikawā.

ʻAʻole i kaupalena ʻia nā huahana a Xingcheng i nā paipu kila, akā hana pū ia i ke kila hali, ke kila kaʻa, a me ke kila ikehu." ʻO ke kūlana alakaʻi honua o Xingcheng ma ke kahua e hoʻokumu i kahi pae hoʻohālikelike no ka ʻoihana kila kūikawā holoʻokoʻa.

Nui nā holomua ʻenehana a me nā hana hou i nā paipu kila humuhumu e hilinaʻi nui nei i ke kākoʻo mea i hāʻawi ʻia e nā ʻoihana kila kūikawā e like me Xingcheng.

Eia kekahi, ʻo Zhejiang Jiuli Special Materials kahi poʻokela huna i ke kahua paipu kila kila ʻole.

He loea ia i nā paipu kūikawā e like me 304, 316L, ke kila kila duplex, a me nā mea hoʻohuihui kūpaʻa i ka pala a me ke kiʻekiʻe o ka mahana, me nā kikoʻī mai Φ6-219mm a me ka mānoanoa o ka paia mai 0.5-18mm, a me ka hiki ke hana ma kahi o 40,000 tons.

Hoʻohana ʻia kāna huahana i ka mana nukelea, nā petrochemicals, ka ikehu hou, a me ka ʻenekinia moana, me ka loaʻa kālā nui ma mua o 34%.

I ka wā e pili ana i ke kila kila a me nā paipu hui kūikawā, he inoa hiki ʻole ke pale ʻia ʻo Jiuli.

Ma ka hema aʻe, ʻo Hunan Hengyang Hualing Steel Pipe, i hoʻokumu ʻia i ka makahiki 1958... He ʻoihana paipu kila humuhumu ʻoihana ko Jianchang ma ka honua holoʻokoʻa.

ʻO ke anawaena o nā kikoʻī huahana mai 32-762mm, a hiki nō hoʻi iā ia ke hana i nā ʻōmole huinahā a me nā ʻōmole huinahā.

I ka makahiki 2025, e hana pū ana me Danieli e kūkulu i ka laina hana ʻōwili wela hoʻomau nui loa o ka honua, i hoʻolālā ʻia me ke anawaena paipu kiʻekiʻe loa o Φ24 ʻīniha.

ʻO ke kūlana kila kiʻekiʻe loa no nā paipu ʻaila a me ke kinoea ʻo HS155V, no nā paipu laina hiki iā ia ke hōʻea i ka X100Q, a no nā paipu ipu kaomi hiki iā ia ke kū i nā mahana a hiki i ka 600℃.

I ka pōkole: he mana nui i ka hana kūloko kiʻekiʻe.

ʻO ka mea hope loa, ke nānā aku nei i ke Komohana Hema o Kina, ʻo Panzhihua Iron & Steel Group Chengdu Steel & Vanadium. Me ka mana hana makahiki o 2.12 miliona tons, uhi kāna huahana i nā paipu aila, nā paipu paila, a me nā mea ʻē aʻe, a loaʻa iā ia ka palapala hōʻoia API a me nā laikini hana lako palekana nukelea.

Nā kikoʻī: Φ6-720mm, ka mānoanoa o ka paia 0.5-45mm ua hāʻawi nui nā paipu kila wili ʻole i nā ʻoihana e like me ka pale kaua aupuni, ka aerospace, ka mana nukelea, a me nā paila.

ʻO Pangang (Pangang Group) ka mea hana paipu kila humuhumu ma ke Komohana Hema o Kina me ka laulā piha o nā kikoʻī huahana.

ʻOiaʻiʻo, he nui nā ʻoihana ʻē aʻe i ʻōlelo ʻole ʻia, e like me Jingjiang Special Steel, Qingdao Special Steel, Zhejiang Taifu, a me Dalipu, Molong, Chengde, Longchuan, Jianlong, Huarun, Changjiang, a pēlā aku. Ke hāʻawi nei lākou i nā hāʻawi nui a leo ʻole i ke kūkulu ʻana i ka ikehu o ka ʻāina, nā ʻoihana hana, a me ka ʻoihana hoʻokuʻu aku. Mahalo nui mākou iā lākou.

Ua hana kā mākou hui i ka ʻoihana paipu kila no 20 mau makahiki a ua lōʻihi ka launa pū ʻana me kēia mau hale wili kila. ʻO kēlā me kēia ʻano paipu kila āu e pono ai, e kōkua mākou iā ʻoe e ʻike i ka mea hoʻolako kūpono loa. Na ʻoe e mālama i ke kau ʻana o ke kauoha, a na mākou e mālama i ka hoʻohālikelike ʻana.
