Nā Paipu Hollow-Section no nā laina kinoea ma lalo o ka honua

ʻO ka wehewehe pōkole:

Ke kūkulu ʻana i nā paipu kinoea kūlohelohe ma lalo o ka honua, he mea koʻikoʻi ke koho ʻana i nā mea e hōʻoia ai i ka palekana a me ka pono o ka ʻōnaehana.ʻO nā paipu kūkulu ʻia ʻana o ka ʻāpana hollow, ʻoi aku ka nui o nā paipu arc submerged spiral, ke lilo nei i mea kaulana ma muli o ko lākou ikaika ʻoi aku, paʻa a me ka pale ʻana i ka corrosion.Ma kēia blog, e ʻimi mākou i ke koʻikoʻi o ka hollow-ʻO nā paipu kūkulu ʻāpana i ke kūkulu ʻana i nā pipeline kinoea kūlohelohe a me nā pōmaikaʻi nui a lākou e hāʻawi ai.

E hoʻouna i ka leka uila iā mākou

Poʻo poʻo i loko o ka pōpaipushoʻohana nui ʻia i ke kūkulu ʻana i nā laina kinoea kūlohelohe ma lalo o ka honua ma muli o kā lākou hana hana kūʻokoʻa.Hoʻokumu ʻia nā paipu ma ka hana ʻana i nā wili o ke kila wela i loko o ke ʻano spiral a laila wili iā lākou me ka hoʻohana ʻana i ke kaʻina hana wili arc i lalo.Hoʻopuka kēia i nā paipu arc submerged Spiral ikaika kiʻekiʻe me ka mānoanoa like ʻole a me ka pololei o ka dimensional, e hoʻolilo iā lākou i mea kūpono no ka lawe ʻana i ke kinoea kūlohelohe ma lalo o ka honua.

ʻO kekahi o nā pōmaikaʻi nui o nā paipu hollow-section structural pipe ko lākou kūpaʻa maikaʻi loa.Ke kanu ʻia ma lalo o ka lepo, ʻike ʻia nā paipu kinoea kūlohelohe i ka makū, nā kemika lepo a me nā mea corrosive ʻē aʻe.Hoʻonohonoho pono ʻia nā paipu arc submerged spiral e kū i kēia mau kūlana paʻakikī o lalo o ka honua, e hōʻoia ana i ka lōʻihi a me ka hilinaʻi o nā pipeline kinoea kūlohelohe.

Ma waho aʻe o ka pale ʻana i ka corrosion,nā paipu hollow-section structural pipeshāʻawi i ka ikaika a me ka paʻa, e kūpono iā lākou no nā hoʻonohonoho ʻana i lalo.ʻO ka hoʻolālā spiral o kēia mau paipu e hāʻawi maikaʻi loa i ka hiki ke lawe i ka ukana, e ʻae iā lākou e pale i ke kaumaha o ka lepo a me nā mea ʻē aʻe o waho me ka ʻole o ka hoʻopaʻapaʻa ʻana i ko lākou kūpaʻa.He mea koʻikoʻi kēia ma nā wahi me ka geology paʻakikī, kahi e hiki ai i nā paipu ke kū i ka neʻe ʻana o ka ʻāina a me ka noho ʻana.

Hoʻohui ʻia, ʻike ʻia nā paipu hollow section no ko lākou versatility a me ka uku-pono.Hele mai lākou i nā ʻano nui a me nā mānoanoa a hiki ke hoʻopili ʻia e hoʻokō i nā koi kikoʻī o nā papahana pipeline kūlohelohe honua.ʻO kēia ka mea e hōʻemi ai i ka pono o nā mea hoʻohui hou a me ka hoʻopili ʻana, ka hopena o ka hoʻokomo wikiwiki ʻana a hoʻohaʻahaʻa i nā kumukūʻai holoʻokoʻa.ʻO ke ʻano māmā o kēia mau paipu e ʻoi aku ka maikaʻi o ka lawe ʻana a me ka lawelawe ʻana, e hāʻawi hou i ka mālama kālā.

I ka wā e pili ana i ka palekana a me ka pono olaina kinoea ma lalo o ka honua, he mea ko'iko'i ke koho mea.ʻO nā paipu hollow-section structural pipes, ʻoi aku ka spiral submerged arc pipes, hui pū i ka ikaika, ka lōʻihi, ka pale ʻana i ka corrosion a me ka maikaʻi o ke kumu kūʻai, e hoʻolilo iā lākou i mea kūpono no ka lawe ʻana i ke kinoea kūlohelohe ma lalo o ka honua.Ma ka hoʻokomo ʻana i nā pipeline kiʻekiʻe kiʻekiʻe i hoʻolālā ʻia no nā keʻena lalo, hiki i nā hui kinoea ke hōʻoia i ka hilinaʻi a me ka lōʻihi o kā lākou hana ʻoiai e hōʻemi ana i nā kumukūʻai mālama a hoʻoponopono i ka wā lōʻihi.

I ka hōʻuluʻulu manaʻo, pāʻani nui nā paipu hollow cross-section i ke kūkulu ʻana i nā laina kinoea kūlohelohe ma lalo o ka honua.ʻO kona kūpaʻa ʻoi aku ka maikaʻi o ka corrosion, ka ikaika ʻoi aku ka maikaʻi a me ka maikaʻi o ke kumu kūʻai, ʻo ia ka mea i koho mua ʻia no nā papahana hoʻokele kinoea maoli.Ma ke koho ʻana i nā mea pono no nā keʻena ma lalo o ka honua, hiki i nā hui kinoea kūlohelohe ke mālama i ka palekana a me ka hilinaʻi o kā lākou ʻoihana, ma hope e kōkua i ka hāʻawi ʻana i ke kinoea kūlohelohe i nā mea kūʻai aku.
