Hoʻolauna Huahana

Hōʻike kā mākou huahana hou i kahi hui spiral mau, i hana ʻia mai nā ʻāpana kila kiʻekiʻe i wili ʻia. ʻAʻole kēia hana ʻokoʻa e hoʻonui i ka lōʻihi o ka paipu, akā hāʻawi pū kekahi i ka ikaika like ʻole, i mea kūpono no nā pipeline kinoea kūlohelohe a me nā ʻoihana koʻikoʻi ʻē aʻe.

Hoʻokumu ʻia kā mākou mau paipu kila welded spiral e kū i nā kaomi kiʻekiʻe a me nā kūlana koʻikoʻi, e hōʻoiaʻiʻo ana i ka lawe ʻana i ke kinoea kūlohelohe palekana a hilinaʻi. Hoʻomaopopo mākou i ke koʻikoʻi o ka mālama ʻana i ka pono o nā pipeline gas kūlohelohe, a ua hoʻāʻo ikaika ʻia kā mākou huahana e hōʻoia i ka hoʻokō ʻana i nā kūlana ʻoihana a me nā lula.

Ke koho ʻoe i kā mākoupaipu kila wiliwili ʻia, ke hoʻolilo nei ʻoe i kahi hoʻonā e hoʻomāhuahua i ka palekana me ka ʻole o ka hoʻokō ʻana i ka hana. Inā ʻoe e hana nei i ka ʻoihana ikehu, kūkulu hale, a i ʻole ʻoihana ʻē aʻe e koi ana i kahi hoʻonā paipu koʻikoʻi, loaʻa iā mākou nā huahana e hoʻokō i kāu mau pono.

Pōmaikaʻi Hui

Aia i loko o ka puʻuwai o Cangzhou City, Hebei Province, ua alakaʻi kā mākou hale hana i ka ʻoihana paipu kila mai kona hoʻokumu ʻia ʻana i ka makahiki 1993. Hoʻopili ka hale hana i kahi ʻāpana o 350,000 square meters a ua hoʻolako ʻia me ka ʻenehana ʻokiʻoki a pili i nā kūlana mana kiʻekiʻe. Me ka nui o nā waiwai o RMB 680 miliona a me 680 mau limahana i hoʻolaʻa ʻia, ua paʻa mākou i ka hāʻawi ʻana i nā huahana e hoʻokō i nā koi koʻikoʻi o kā mākou mea kūʻai.

Pōmaikaʻi Huahana

Aia nā paipu kinoea i hana ʻia ma ka mea kanu i nā hui spiral mau, i hana ʻia mai nā ʻāpana kila i wiliwili ʻia. Hāʻawi kēia hoʻolālā hou i ka ikaika like ʻole, e hana ana i kēia mau paipu i kūpono no nā noi koi e like me nā pipeline kinoea kūlohelohe. ʻO ka hana paʻa e hōʻoia i ka hiki i nā paipu ke kū i nā koʻikoʻi kiʻekiʻe a me nā kūlana kūlohelohe koʻikoʻi, he mea koʻikoʻi i ka mālama ʻana i ka palekana a me ka pono o ka lawe ʻana i ke kinoea maoli.

Ma ka ʻaoʻao maikaʻi, ʻo ka ikaika a me ka lōʻihi o kēia mau paipu, ʻo ia ka lōʻihi o ke ola ʻana a ʻaʻole pono e hoʻololi pinepine, e hōʻemi ana i nā kumukūʻai mālama.

Hoʻohui ʻia, kūpaʻa lākou i ka corrosion a me nā mea ʻē aʻe o ke kaiapuni, e hoʻolilo iā lākou i koho hilinaʻi no ka hoʻohana lōʻihi.

Huahana

Ma ka lalo, ke kumu kūʻai mua o ka maikaʻipaipu kinoeahiki ke kiʻekiʻe, hiki ke pale i kekahi mau hui mai ka hoʻokomo kālā.

Eia kekahi, hiki ke paʻakikī ke kaʻina hana a koi i ka hana akamai, hiki ke hoʻonui i nā lilo holoʻokoʻa.

Ka hopena nui

ʻO kekahi o nā huahana koʻikoʻi o ka mea kanu, ʻo ia kona mau paipu kinoea hui pū. Hana ʻia me ka hoʻohana ʻana i ke kaʻina hana pono o nā ʻāpana kila i hoʻopili ʻia, ʻo kēia mau paipu e hōʻike ana i kahi hale kūʻokoʻa e hāʻawi ana i ka ikaika like ʻole. Ua kūpono kēia hoʻolālā hoʻolālā no nā noi koi, e like me nā pipeline kinoea kūlohelohe, kahi mea nui ka lōʻihi a me ka hilinaʻi.

ʻO ke kumu nui o kēia mau pipeline gas ke kū i nā kaomi kiʻekiʻe a me nā kūlana koʻikoʻi e hōʻoia i ka lawe palekana ʻana o ke kinoea kūlohelohe. ʻAʻole hoʻomaikaʻi wale ka ʻenehana welding spiral i ka paʻa o ka pipeline, akā hāʻawi pū kekahi i ka hoʻolālā hoʻolālā, kūpono ia no nā ʻano hoʻonohonoho hoʻonohonoho. He mea koʻikoʻi kēia no kahi ʻoihana i mea nui ka palekana a me ka pono.

Ke hoʻomau nei ka koi no ke kinoea kūlohelohe, e ulu nui ana ka hana o nā pipeline kūlohelohe kiʻekiʻe. ʻO ka ʻenehana hana kiʻekiʻe i hui pū ʻia me ka hoʻokō ʻana i ka maikaʻi ua lilo kēia ʻoihana ʻo Cangzhou i mea pāʻani nui i ka ʻoihana ikehu.
