Weld Tube Me ka Hana Pono

ʻO ka wehewehe pōkole:

Ke hoʻohana nei kēia ʻenehana i nā wela kiʻekiʻe e hana i kahi paʻa paʻa a paʻa i waena o nā paipu, e hōʻoia ana i kā mākou huahana e hāʻawi i ka hana hilinaʻi ʻoiai ma nā wahi paʻakikī loa. Inā ʻoe i loko o ka ʻoihana kinoea maoli a makemake paha i nā ʻōnaehana paipu hilinaʻi no nā noi ʻē aʻe, e hui ana kā mākou paipu a ʻoi aku i kāu mau manaʻo.

Aia kā mākou hale hana ma Cangzhou, Hebei Province, a aia mākou i mua o ka hana ʻana i nā paipu kila kiʻekiʻe mai ko mākou hoʻokumu ʻana i ka makahiki 1993. Hoʻopili kā mākou hale hana i kahi ʻāpana o 350,000 square meters, me ka nui o ka waiwai o RMB 680 miliona, hiki ke hana i 400,000 tons o nā paipu kila spiral i kēlā me kēia makahiki, a loaʻa iā 680 ʻoihana akamai.

Hoʻolauna Huahana

Hōʻike ʻia kā mākou kūpaʻa i ka maikaʻi i kā mākou kaʻina hana wili arc meticulous, kahi hana koʻikoʻi i ka hana ʻana i kā mākou paipu wiliwili spiral. Ke hoʻohana nei kēia ʻenehana i nā wela kiʻekiʻe e hana i kahi paʻa paʻa a paʻa i waena o nā paipu, e hōʻoia ana i kā mākou huahana e hāʻawi i ka hana hilinaʻi ʻoiai ma nā wahi paʻakikī loa. Inā ʻoe i loko o ka ʻoihana kinoea maoli a makemake paha i nā ʻōnaehana paipu hilinaʻi no nā noi ʻē aʻe, e hui ana kā mākou paipu a ʻoi aku i kāu mau manaʻo.

Me ka nānā ʻana i ka maikaʻi a me ka hana hou, haʻaheo mākou iā mākou iho i ka hāʻawi ʻana i nā welds paipu e hōʻoiaʻiʻo i ka hana mau loa. ʻAʻole wale kā mākoupaipu wiliwili spiralikaika a paʻa hoʻi, maikaʻi loa lākou, e hoʻolilo iā lākou i mea kūpono no nā papahana e pono ai ka hilinaʻi a me ka lōʻihi.

Hiʻona nui

ʻO kekahi o nā hiʻohiʻona nui o ka wili paipu ʻo ia ka hilinaʻi ʻana i ka wili arc, kahi ʻenehana e hoʻohana ai i nā wela 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 ka nui o nā noi i koʻikoʻi ka palekana a me ka hana, e like me ka lawe ʻana i ke kinoea kūlohelohe.

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

Eia kekahi, ʻo ka pololei a me ka ʻike i koi ʻia no ka wili paipu e hōʻike pū ana i ka kūpaʻa o ka ʻoihana i ka maikaʻi. Ma ka hoʻokomo ʻana i ka ʻenehana holomua a me ka limahana akamai, ʻo ka mea kanu ʻo Cangzhou e hōʻoia i kēlā me kēia paipu welded spiral e hoʻokō i nā kūlana ʻoihana koʻikoʻi, 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 pōmaikaʻi koʻikoʻi o ka welding tube ʻo ia ka hiki ke hana i nā hui ikaika e hiki ke kū i nā pilikia kiʻekiʻe a me nā kūlana koʻikoʻi. He mea koʻikoʻi kēia i ka ʻoihana kinoea kūlohelohe, kahi e koʻikoʻi ai ka pono o ka pipeline. ʻO ke kaʻina hana kuʻihao arc e hōʻoia i kawili paipuʻaʻole ikaika wale nō akā paʻa nō hoʻi, e hōʻemi ana i ka hopena o nā leaks a me nā hemahema. Eia kekahi, ʻo ka maikaʻi o ka welding paipu e hiki ai i nā mea hana ke hana wikiwiki i ka nui o ka paipu kila spiral e hoʻokō i ka koi ulu mākeke.

Huahana

Pono ke kaʻina hana i nā limahana akamai a me ka hoʻomalu pololei ʻana i nā ʻāpana wili e pale aku i nā hemahema e like me ka porosity a i ʻole ka hui ʻana. Hiki i kēia mau pilikia ke hoʻololi i ka maikaʻi o ka huahana hope a alakaʻi i nā pōʻino palekana.

Eia kekahi, hiki i nā wela kiʻekiʻe o ka welding arc ke hoʻokomo i nā koʻikoʻi koena i ka mea, hiki ke hoʻopili i ka hana lōʻihi o ka pipeline.

FAQ

Q1: He aha ka arc welding?

ʻO ka welding Arc he ʻano hana e hoʻohana ai i nā wela kiʻekiʻe i hana ʻia e ke arc uila e hoʻoheheʻe a hoʻohui pū i nā ʻāpana metala. No ka paipu spiral welded, pono kēia ʻano e hana i kahi pilina ikaika ma waena o nā paipu, he mea koʻikoʻi i ka hana a me ke ola o ka paipu.

Q2: No ke aha he mea koʻikoʻi ka hoʻoheheʻe ʻana arc no nā pipeline kinoea kūlohelohe?

Pono nā paipu kinoea kūlohelohe i nā kūlana palekana a hilinaʻi. ʻO ke kaʻina hana hoʻoheheʻe arc e hōʻoia i ka hiki i nā hui weld ke kū i nā koʻikoʻi kiʻekiʻe a pale aku i ka corrosion, i mea kūpono no ka lawe ʻana i ke kinoea kūlohelohe ma kahi lōʻihi.

Q3: Aia i hea kāu hui?

Aia kā mākou hale hana ma Cangzhou, Hebei Province, kahi i ʻike ʻia no kona ikaika ʻoihana. Ua hoʻokumu ʻia kā mākou hui ma 1993 a ua ulu nui ʻo ia e uhi i kahi ʻāpana o 350,000 square square a hoʻohana i nā limahana hoʻolaʻa 680.

Q4: He aha kāu mana hana?

Haʻaheo mākou i ka hana ʻana i 400,000 tone o ka paipu kila spiral i kēlā me kēia makahiki. He hōʻike kēia leo hana hoʻohiwahiwa i kā mākou kūpaʻa i ka maikaʻi a me ka pono i kā mākou hana hana.
