Nā Pōmaikaʻi o ka hoʻohana ʻana i nā paipu kila i hoʻopaʻa ʻia ma lalo o ka honua no nā paipu wai lalo

ʻO nā pono o ka hoʻohana ʻana i ka Spiral Submerged Arc Welded Steel Pipes No nā Pipeline wai ma lalo o ka honua.

ʻO ka wehewehe pōkole:

Ke kau nei i nā laina wai ma lalo o ka honua, pono e koho i ke ʻano paipu kūpono e hōʻoia i ka lōʻihi a me ka lōʻihi.ʻO kahi koho kaulana no nā laina wai ma lalo o ka honua he paipu welded spiral, i ʻike ʻia ʻo SSAW steel pipe.

E hoʻouna i ka leka uila iā mākou

paipu kila SSAWhe ʻano paipu wiliwili ʻia i loko o ka honua i hoʻohana mau ʻia i nā ʻano noi like ʻole, me nā laina wai lepo.ʻO kāna kaʻina hoʻoheheʻe spiral kū hoʻokahi e hoʻopuka i nā paipu nui-diameter me ka mānoanoa pā paʻa, kūpono ia no ka lawe ʻana i ka wai ma lalo o ka honua.

ʻO kekahi o nā pōmaikaʻi nui o ka hoʻohana ʻana i ka spiral submerged arc welded steel pipe no nā laina wai honua ʻo ia kona ikaika kiʻekiʻe a paʻa.Hoʻokumu ke kaʻina hoʻoheheʻe spiral i kahi paipu ikaika a hilinaʻi e hiki ke pale i ke kaomi a me ke kaumaha o ke kanu ʻana ma lalo o ka lepo.He mea koʻikoʻi kēia ikaika i ka pale ʻana i ka leak a me ka hōʻoia ʻana i ka kūpaʻa lōʻihi o nā paipu wai.

Hoʻohui ʻia, kūpaʻa ka paipu kila SSAW i ka corrosion, e lilo ia i koho maikaʻi loa no nā noi ma lalo o kahi e ʻike ʻia ai nā paipu i ka wai a me nā mea ʻē aʻe.ʻO kēia kūpaʻa corrosion e kōkua i ka hoʻonui ʻana i ke ola o kāu mau paipu a hōʻemi i ka pono no ka mālama pinepine ʻana a me ka hoʻoponopono ʻana.

ʻO kekahi pōmaikaʻi ʻē aʻe o ka hoʻohana ʻana i ka paipu kila arc submerged arc no nā laina wai honua ʻo ia ka maʻalahi a me ka hiki ke hoʻololi.Hiki i ke kaʻina hana hoʻoheheʻe spiral ke hana i nā paipu o nā anawaena like ʻole, i kūpono ia no nā ʻano noi paipu wai.Hoʻohui hou, ʻo ka maʻalahi o ka paipu kila SSAW e maʻalahi ke hoʻouka a hana, ʻoi aku hoʻi i nā wahi me nā ʻāina paʻakikī a i ʻole nā mea pilikia.

a.Ua koho ʻia ke ʻano deoxidation penei: FF: Ke kila make loa i loaʻa nā mea hoʻopaʻa naikokene i nā nui e hiki ai ke hoʻopaʻa i ka nitrogen i loaʻa (e laʻa me min. 0,020 % ka huina Al a i ʻole 0,015 % soluble Al). b.ʻAʻole pili ka waiwai kiʻekiʻe no ka nitrogen inā hōʻike ka haku mele ʻana i ka liʻiliʻi loa o ka maʻiʻo Al o 0,020 % me ka palena liʻiliʻi o Al/N o 2:1, a i ʻole inā lawa nā mea hoʻopaʻa paʻa N ʻē aʻe.E hoʻopaʻa ʻia nā mea hoʻopaʻa N i loko o ka Palapala Nānā.

Ma waho aʻe o ka ikaika, ka lōʻihi, a me ka maʻalahi, ʻo ka spiral submerged arc welded steel pipe he kumu kūʻai maikaʻi ke hoʻohālikelike ʻia me nā ʻano paipu ʻē aʻe.ʻO ke kaʻina hana wiliwili spiral e hōʻemi ana i nā kumukūʻai hana, e lilo ia i koho ʻoi aku ka waiwai no nā papahana paipu wai nui.ʻO ka lōʻihi lōʻihi a me nā koi mālama haʻahaʻa o ka paipu kila SSAW e kōkua pū i ka mālama kālā holoʻokoʻa i ke ola o ka laina wai.

Ma ke ʻano holoʻokoʻa, nui nā pōmaikaʻi o ka hoʻohana ʻana i ka paipu kila arc submerged arc no nā laina wai honua, me ka ikaika kiʻekiʻe, ka lōʻihi, ka pale ʻana i ka corrosion, ka maʻalahi, a me ke kumukūʻai.ʻO kēia mau hiʻohiʻona e lilo ia i mea hilinaʻi a kūpono hoʻi no ka lawe ʻana i ka wai ma lalo o ka honua, inā paha no ka ʻoihana kaona, nā noi ʻoihana, a i ʻole nā mea mahiʻai.

I ka hōʻuluʻulu ʻana, i ka wā e koho ai i ka paipu maikaʻi loano nā laina wai lalo, spiral submerged arc welded steel pipe ka mea maikai loa.Hāʻawi ka hana spiral-welded i ka ikaika, ka lōʻihi a me ka pale ʻana i ka corrosion e pono ai no ka hana lōʻihi, ʻoiai ʻo kona maʻalahi a me ka maikaʻi o ke kumukūʻai e lilo ia i mea koho maikaʻi no nā papahana paipu wai o nā nui āpau.Ma ke koho ʻana i ka paipu kila arc submerged arc, hiki iā ʻoe ke hōʻoia i ka hilinaʻi a me ka lōʻihi o kāu mau laina wai lalo, e hāʻawi iā ʻoe i ka maluhia o ka noʻonoʻo a me ka hilinaʻi i kāu ʻōnaehana wai.
