Nui Anawaena Welded Pipes Steel Tubular Piles

ʻO ka wehewehe pōkole:

Ua hauʻoli mākou i ka hoʻomaka ʻana i kā mākou huahana hou i nā puʻu tubular kila, i hoʻolālā ʻia e hāʻawi i ka hoʻomaʻamaʻa maikaʻi loa no nā ʻano noi like ʻole, ʻoi aku ka cofferdams.Hōʻike kēia mau puʻupuʻu i ka hoʻolālā ʻāwili ʻana a i ʻole ka pōʻai no ka ikaika like ʻole a me ka lōʻihi, e hoʻopili pono ana a pale i ka komo ʻana o ka wai, ka lepo a me ke one.

E hoʻouna i ka leka uila iā mākou

Puʻu paipu kilahana ʻia me ka hoʻohana ʻana i nā mea kiʻekiʻe kiʻekiʻe a me ka ʻenehana kiʻekiʻe, e hilinaʻi nui ʻia no kēlā me kēia papahana kūkulu.Hoʻohana pinepine ʻia kēia mau puʻupuʻu i nā cofferdams a ʻo kā lākou hoʻolālā hoʻolālā ikaika e hōʻoia i ka palekana a me ke kūpaʻa e pono ai no nā kumu a me nā hana ʻoihana ʻē aʻe.

ʻO kā mākoupaipu wiliwili anawaena nuisʻo ia ka iwi kuamoʻo o kēia mau puʻu paipu kila, e hoʻonui ana i ko lākou hilinaʻi a me ka hana.Ma o nā kaʻina hana hoʻoheheʻe maikaʻi a me ka maikaʻi, hōʻoia mākou e hoʻokō kēlā me kēia puʻu i nā kūlana ʻoihana kiʻekiʻe.Hāʻawi kēia mau paipu i ka maʻalahi a me ka lōʻihi, e ʻae ana i nā puʻu paipu kila e kū i nā kūlana koʻikoʻi a me nā kaiapuni paʻakikī.

Ma ke ʻano he mea hana alakaʻi i ka ʻoihana, ʻo Cangzhou Spiral Steel Pipes Group Co., Ltd. he mau hale hana hou e uhi ana i kahi o 350,000 mau mika square.Me ka waiwai waiwai a hiki i ka 680 miliona yuan, hoʻokomo mākou i ka ʻenehana ʻokiʻoki a me nā mea hana e hōʻoia i ka hana kiʻekiʻe loa.Eia kekahi, ʻo kā mākou limahana limahana o 680 mau limahana e hōʻoia i kēlā me kēia huahana e hoʻopaʻa i nā loiloi maikaʻi ma mua o ka hiki ʻana i nā lima o kā mākou mea kūʻai waiwai.

ʻO kā mākou hale hana he 400,000 tons o nā paipu kila spiral a me ka waiwai hoʻopuka o 1.8 biliona yuan.Hōʻike kēia milestone i ko mākou kūpaʻa i ka hoʻolako ʻana i ka maikaʻi o ka lawelawe a me ka hoʻokō ʻana i nā pono o kā mākou mea kūʻai waiwai ma ka ʻāina a me ka honua.

Puʻu paipu kilai hui pū ʻia me kā mākou mau paipu welded anawaena nui e hāʻawi i ka versatility maikaʻi loa, e kūpono ana iā lākou no ka nui o nā noi.Ma waho aʻe o nā cofferdams, hoʻohana nui ʻia kā mākou mau puʻupuʻu i ke kūkulu ʻana i ke alahaka, nā ʻoihana awa a me nā papahana kai ʻē aʻe.ʻO ka hoʻolālā ʻokoʻa ʻokoʻa a i ʻole ka pōʻai o kēia mau puʻupuʻu e hōʻoia i ka maikaʻi o ka wai a me ka paʻa ʻana o ka lepo me ka hāʻawi ʻana i kahi papa hana ikaika.

ʻO ka hoʻokō ʻana o kā mākou hui i ka maikaʻi, ka ʻoihana a me ka ʻoluʻolu o ka mea kūʻai aku e hoʻoikaika mau iā mākou i kā mākou hana hana a hoʻomohala i nā hopena hou.Hoʻopili mākou i nā kūlana hoʻomalu maikaʻi koʻikoʻi e hōʻoia i kā mākou huahana i ke kūlana kiʻekiʻe loa a hoʻokō a ʻoi aku paha i kāu mau manaʻo.

I ka hōʻuluʻulu manaʻo,puʻupuʻu kilake hoʻololi nei i ka ʻoihana kūkulu me ka ikaika a me ka lōʻihi o kā mākou paipu welded anawaena nui.Me ko lākou hiki ke kū i nā kūlana paʻakikī a me kā lākou hoʻohana kūikawā i nā cofferdams, hāʻawi kēia mau puʻupuʻu i ka palekana 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.

Mua: Nā Paipu Hollow-Section Structural Paipu A me kā lākou kuleana i loko o ka ʻaila Pipeline Infrastructural

Aʻe: Kuʻi ʻana i ka paipu hao ʻeleʻele no ka paipu wai o ka hale
