ʻO ke kiʻi i hōʻike ʻia ʻo Tube Weld me ka hana hilinaʻi

Wehewehe Pōkole:

Hoʻohana kēia ʻenehana i nā mahana kiʻekiʻe e hana i kahi pilina ikaika a paʻa ma waena o nā paipu, e hōʻoiaʻiʻo ana e hāʻawi kā mākou huahana i ka hana hilinaʻi ʻoiai ma nā wahi paʻakikī loa. Inā ʻoe ma ka ʻoihana kinoea kūlohelohe a i ʻole makemake ʻoe i nā hopena paipu hilinaʻi no nā noi ʻē aʻe, e hoʻokō a ʻoi aku kā mākou mau paipu i kāu mau manaʻolana.

Pōmaikaʻi o ka ʻoihana

Aia kā mākou hale hana ma Cangzhou, Hebei Province, a ua noho mākou ma ke alo o ka hana ʻana i nā paipu kila kiʻekiʻe mai ko mākou hoʻokumu ʻia ʻana i ka makahiki 1993. Uhi kā mākou hale hana i kahi ʻāpana o 350,000 mika kuea, me ka huina waiwai o RMB 680 miliona, hiki ke hana i 400,000 tons o nā paipu kila wili i kēlā me kēia makahiki, a he 680 mau loea akamai.

Hoʻolauna Huahana

Hōʻike ʻia ko mākou kūpaʻa i ka maikaʻi loa i kā mākou kaʻina hana kuʻi arc akahele, he ʻanuʻu koʻikoʻi ia i ka hana ʻana o kā mākou paipu wiliwili. Hoʻohana kēia ʻenehana i nā mahana kiʻekiʻe e hana i kahi pilina ikaika a paʻa ma waena o nā paipu, e hōʻoiaʻiʻo ana e hāʻawi kā mākou huahana i ka hana hilinaʻi ʻoiai ma nā wahi paʻakikī loa. Inā ʻoe ma ka ʻoihana kinoea kūlohelohe a i ʻole makemake i nā hopena paipu hilinaʻi no nā noi ʻē aʻe, e hoʻokō a ʻoi aku kā mākou mau paipu i kāu mau manaʻolana.

Me ka nānā ʻana i ka maikaʻi a me ka hana hou, haʻaheo mākou i ka hāʻawi ʻana i nā wili paipu e hōʻoiaʻiʻo ana i ka hana lōʻihi. ʻAʻole wale kā mākoupaipu wili i hoʻopaʻa ʻiaikaika a paʻa hoʻi, he hana kūpono loa lākou, e kūpono ana iā lākou no nā papahana e pono ai ka hilinaʻi a me ke kūpaʻa.

Hiʻohiʻona nui

ʻO kekahi o nā hiʻohiʻona koʻikoʻi o ka hoʻoheheʻe ʻana i ka paipu ʻo ia kona hilinaʻi ʻana i ka hoʻoheheʻe ʻana i ke arc, kahi ʻenehana e hoʻohana ana i nā mahana kiʻekiʻe e hana i nā pilina ikaika a paʻa ma waena o nā paipu kila. He mea koʻikoʻi ke kaʻina hana no ka hōʻoia ʻana i ka pono a me ka hilinaʻi o ka huahana hope loa, ʻoi aku hoʻi i nā noi kahi e koʻikoʻi ai ka palekana a me ka hana, e like me ka lawe ʻana i ke kinoea kūlohelohe.

ʻO ke kaʻina hana kuʻi arc e pili ana i ka hoʻoheheʻe ʻana i nā kihi o ka paipu a me ka hoʻohui ʻana iā lākou, e hana ana i kahi pilina maʻemaʻe e hiki ke kū i ke kaomi kiʻekiʻe a me nā kūlana koʻikoʻi. ʻAʻole wale kēia ʻano hana e hoʻonui i ka ikaika o ka paipu, akā e hoʻolōʻihi pū i kona ola lawelawe, e lilo ia i koho makemake ʻia no nā ʻano hana ʻoihana like ʻole.

Eia kekahi, ʻo ka pololei a me ka ʻike loea e pono ai no ka hoʻoheheʻe ʻana i nā paipu e hōʻike pū ana i ka kūpaʻa o ka ʻoihana i ka maikaʻi. Ma ka hoʻopukapuka kālā ʻana i ka ʻenehana holomua a me ka poʻe hana akamai, hōʻoia ka hale hana ʻo Cangzhou e hoʻokō ana kēlā me kēia paipu i hoʻoheheʻe ʻia i nā kūlana ʻoihana paʻa, e hāʻawi ana i nā mea kūʻai aku i ka maluhia o ka noʻonoʻo a me ka hilinaʻi i ka huahana.

Pōmaikaʻi Huahana

ʻO kekahi o nā pono koʻikoʻi o ka hoʻoheheʻe ʻana i ka paipu, ʻo ia kona hiki ke hana i nā hui ikaika e hiki ke kū i nā kaomi kiʻekiʻe a me nā kūlana koʻikoʻi. He mea nui loa kēia i ka ʻoihana kinoea kūlohelohe, kahi e koʻikoʻi ai ka pono o ka pipeline. Hōʻoia ka hana hoʻoheheʻe arc i kawili ʻana o ka paipuʻaʻole wale ka ikaika akā kūlike nō hoʻi, kahi e hōʻemi ai i ka pilikia o nā leaka a me nā hemahema. Eia kekahi, ʻo ka pono o ka hoʻopili ʻana i ka paipu e hiki ai i nā mea hana ke hana koke i nā nui o ka paipu kila wili e hoʻokō ai i ka noi mākeke e ulu ana.

Ka hemahema o ka huahana

Pono ke kaʻina hana i nā limahana akamai a me ka kaohi pololei o nā palena kuʻihao e pale aku i nā hemahema e like me ka porosity a i ʻole ka nele o ka fusion. Hiki i kēia mau pilikia ke hoʻopilikia i ka maikaʻi o ka huahana hope loa a alakaʻi i nā pōʻino palekana.

Eia kekahi, hiki i nā mahana kiʻekiʻe o ka wili arc ke hoʻolauna i nā koʻikoʻi koena i loko o ka mea, hiki ke hoʻopilikia i ka hana lōʻihi o ka pipeline.

NĀ NĪNAU I NĀ ...

Q1: He aha ka wili ʻākuhi?

ʻO ka wili ʻākuhi he ʻano hana e hoʻohana ana i nā mahana kiʻekiʻe i hana ʻia e kahi ʻākuhi uila e hoʻoheheʻe a hoʻohui i nā pepa metala. No ka paipu wili ʻākuhi, he mea nui kēia ʻano hana e hana i kahi pilina ikaika ma waena o nā paipu, he mea koʻikoʻi ia no ka hana a me ke ola o ka paipu.

Q2: No ke aha he mea nui ka wili ʻana o ke arc no nā paipu kinoea kūlohelohe?

Pono nā paipu kinoea kūlohelohe e hoʻokō i nā kūlana palekana a me ka hilinaʻi paʻa. Hōʻoia ke kaʻina hana kuʻi arc e hiki i nā hui kuʻi ke kū i nā kaomi kiʻekiʻe a pale aku i ka pala, e kūpono ai no ka lawe ʻana i ke kinoea kūlohelohe ma nā wahi lōʻihi.

Q3: Aia i hea kāu ʻoihana?

Aia kā mākou hale hana ma Cangzhou, Hebei Province, kahi wahi i ʻike ʻia no kona ikaika ʻoihana. Ua hoʻokumu ʻia kā mākou hui i ka makahiki 1993 a ua ulu nui e uhi i kahi ʻāpana o 350,000 mika kuea a hoʻolimalima i 680 mau limahana i hoʻolaʻa ʻia.

Q4: He aha kou mana hana?

Ua haʻaheo mākou e hana i 400,000 tone o ka paipu kila wili i kēlā me kēia makahiki. ʻO kēia nui hana kupaianaha he hōʻike ia i kā mākou kūpaʻa i ka maikaʻi a me ka pono i kā mākou kaʻina hana.
