Nā Paipu Welded Anawaena Nui Nā Puʻu Tubular Kiʻi i Hōʻike ʻia

Wehewehe Pōkole:

Ua hauʻoli mākou e hoʻolauna i kā mākou huahana hou o nā paila tubular kila, i hoʻolālā ʻia e hāʻawi i ka pono maikaʻi loa no nā ʻano hana like ʻole, ʻoiai nā cofferdams. Loaʻa i kēia mau paila kahi hoʻolālā piʻo a pōʻai paha no ka ikaika a me ke kūpaʻa ʻole, e hoʻopuni pono ana a pale ana i ke komo ʻana o ka wai, ka lepo a me ke one.

E leka uila mai iā mākou

Nā kikoʻī huahana

Nā Lepili Huahana

Nā paila paipu kilaua hana ʻia me ka hoʻohana ʻana i nā mea hana kiʻekiʻe loa a me ka ʻenehana holomua, e hilinaʻi nui ai lākou no kekahi papahana kūkulu. Hoʻohana pinepine ʻia kēia mau paila i loko o nā cofferdams a ʻo kā lākou hoʻolālā kūkulu ikaika e hōʻoiaʻiʻo ana i ka palekana a me ke kūpaʻa e pono ai no nā kahua a me nā hana ʻoihana ʻē aʻe.

ʻO kā mākoupaipu wili ʻia ke anawaena nuisʻo ia ke kuamoʻo o kēia mau paila paipu kila, e hoʻonui ana i ko lākou hilinaʻi a me ka hana. Ma o ka hoʻopili pono ʻana a me nā kaʻina hana kaohi maikaʻi, hōʻoia mākou e hoʻokō kēlā me kēia paila i nā kūlana ʻoihana kiʻekiʻe loa. Hāʻawi kēia mau paipu i ka maʻalahi a me ke kūpaʻa kūikawā, e ʻae ana i nā paila paipu kila e kū i nā kūlana koʻikoʻi a me nā ʻano ʻino.

Ma ke ʻano he mea hana alakaʻi ʻoihana, loaʻa iā Cangzhou Spiral Steel Pipes Group Co., Ltd. nā hale hana kiʻekiʻe loa e uhi ana i kahi ʻāpana ma mua o 350,000 mika kuea. Me ka waiwai waiwai a hiki i 680 miliona yuan, hoʻopukapuka mākou i nā ʻenehana a me nā lako hana hou loa e hōʻoia i ka hana kiʻekiʻe loa. Eia kekahi, ʻo kā mākou poʻe hana i hoʻolaʻa ʻia o 680 mau limahana e hōʻoiaʻiʻo ana e nānā pono ʻia kēlā me kēia huahana ma mua o ka hiki ʻana i nā lima o kā mākou mea kūʻai aku.

He 400,000 tone o nā paipu kila wili ka nui o ka hana a kā mākou hale hana i kēlā me kēia makahiki a he 1.8 biliona yuan ka nui o ka hana. Hōʻike kēia hanana koʻikoʻi i ko mākou kūpaʻa i ka hāʻawi ʻana i ka lawelawe maikaʻi loa a me ka hoʻokō ʻana i nā pono o kā mākou mea kūʻai aku ma kahi kūloko a ma ka honua holoʻokoʻa.

Nā paila paipu kilai hui pū ʻia me kā mākou mau paipu welded diameter nui e hāʻawi i ka versatility maikaʻi loa, e kūpono ana iā lākou no nā ʻano hana like ʻole. Ma waho aʻe o nā cofferdams, hoʻohana nui ʻia kā mākou mau paila i ke kūkulu ʻana i ke alahaka, nā ʻoihana awa a me nā papahana moana ʻē aʻe. ʻO ka hoʻolālā kū hoʻokahi a poepoe paha o kēia mau paila e hōʻoiaʻiʻo ana i ka paʻa ʻana o ka wai a me ka lepo maikaʻi loa me ka hāʻawi ʻana i kahi ʻōnaehana kūkulu ikaika.

ʻO ke kūpaʻa o kā mākou hui i ka maikaʻi, ka ʻoihana a me ka ʻoluʻolu o ka mea kūʻai aku e hoʻoikaika iā mākou e hoʻomaikaʻi mau i kā mākou mau kaʻina hana a hoʻomohala i nā hoʻonā hou. Hoʻopili mākou i nā kūlana kaohi maikaʻi e hōʻoia i ka maikaʻi o kā mākou huahana a hoʻokō a ʻoi aku paha i kāu mau manaʻolana.

I ka hōʻuluʻulu manaʻo,nā paila tubular kilake hoʻololi nei i ka ʻoihana kūkulu hale me ka ikaika a me ke kūpaʻa o kā mākou paipu welded diameter nui. Me ko lākou hiki ke kū i nā kūlana paʻakikī a me kā lākou hoʻohana kūikawā i nā cofferdams, hāʻawi kēia mau paila i ka pale a me ke kākoʻo like ʻole. E hui pū me Cangzhou Spiral Steel Pipes Group Co., Ltd. e kiʻi i nā huahana kiʻekiʻe e hoʻomaikaʻi i kāu mau papahana a hāʻawi i nā hopena lōʻihi.

Ma mua: ʻO nā paipu kūkulu ʻāpana hollow a me kā lākou kuleana i ke kahua paipu ʻaila

Aʻe: Kuʻihao ʻana i ka paipu kila ʻeleʻele no ka paipu wai kūloko

E kākau i kāu leka ma aneʻi a hoʻouna mai iā mākou
