ʻO ke anu i hoʻokumu ʻia A252 Papa 1 Welded Steel Pipe No nā Paipu Kinoea Kūleʻa
ʻO ASTM A252 kahi maʻamau paipu kila i hoʻopaʻa ʻia i hoʻohana ʻia i nā puʻu kumu, nā puʻu alahaka, nā puʻu pier a me nā kahua ʻenekinia ʻē aʻe.Hoʻolālā ʻia kēia mau paipu kila e kū i nā kaomi kiʻekiʻe a kūpono no ka hoʻohana ʻana i nā ʻano ʻano koi.ʻO kā mākouanu i hoʻokumu ʻia welded structuralhana ʻia nā paipu kinoea mai ke kila A252 Grade 1, i ʻike ʻia no kona kūpaʻa a me ka ikaika.

Hoʻohana ʻia kā mākou kūkulu ʻana i ka paipu kila i ke ʻano hoʻoheheʻe ʻana o ka arc submerged pālua, e hōʻoiaʻiʻo ana i kahi kiʻekiʻe o ka pololei a me ka maikaʻi i kēlā me kēia huahana.Hoʻopili kēia ʻano i ka hoʻopaʻa ʻana i nā paipu kila mai loko a ma waho, e hana ana i kahi paʻa paʻa.ʻO ka hopena hopena, he huahana ia e kūpaʻa loa i ka corrosion a kūpono i ka nui o nā hana ʻoihana a me nā hana kūkulu.
Hoʻolālā pū ʻia kā mākou paipu kino kino i hoʻokumu ʻia i ke anuanu no ka hoʻokō ʻana i nā koi waiwai mīkini kikoʻī i wehewehe ʻia ma ka maʻamau ASTM A252.Wahi a kēia maʻamau, ua māhele ʻia kā mākou paipu kila i ʻekolu mau papa: Papa 1, Papa 2 a me Papa 3, me kēlā me kēia papa e hāʻawi i nā pae like ʻole o ka ikaika a me ka lōʻihi.Hiki i kēia i kā mākou mea kūʻai ke koho i ka papa i kūpono i kā lākou noi kikoʻī a me nā koi hana.
Inā hoʻohana ʻia ma ke ʻano he puʻu kumu no ka hana kūkulu ʻana a i ʻole he ʻāpana o ke alahaka a i ʻole nā pier piling, ua kūkulu ʻia kā mākou paipu kila e kū i nā pilikia paʻakikī.Hāʻawi lākou i ka hana hilinaʻi a me ka lōʻihi lōʻihi, e hoʻolilo iā lākou i mea kūpono no nā ʻano hana ʻenekinia a me nā hana kūkulu.
I ka hōʻuluʻulu ʻana, ua hoʻokumu ʻia kā mākou anu anuanupaipu kinoea, i hana 'ia mai ke kila A252 Grade 1 a i kūkulu 'ia me ka ho'ohana 'ana i ke 'ano o ka wiliwili arc lua i lalo, he mea hilina'i a ki'eki'e loa no ka nui o nā noi koi.Hoʻopili kēia mau paipu kila me nā kūlana ASTM A252 a ua hoʻolālā ʻia e hoʻokō i nā koi waiwai mechanical kūikawā, e hōʻoia ana e hāʻawi lākou i ka hana ʻoi aku ka maikaʻi a me ka lōʻihi.E koho i kā mākou paipu kila no kāu papahana aʻe a ʻike i ka ʻokoʻa o ka maikaʻi a me ka hilinaʻi.
