ʻO A252 Papa 2 Paipu Paipu kila no nā kumu ma ka ʻoihana waho
I loko o ka honua e ulu mau nei o ka hoʻomohala ʻana i nā ʻoihana, ʻo ka pono o nā mea hilinaʻi a paʻa ka mea nui. Haʻaheo mākou i ka hāʻawi ʻana i kā mākou mau puʻu waiwai, i hoʻolālā ʻia e hoʻokō i nā kūlana koʻikoʻi i koi ʻia no nā paipu kinoea lalo. Hana ʻia kā mākou mau puʻupuʻu me ka pololei, e hōʻoia ana e kaupaona ʻia kēlā me kēia puʻu e hōʻoia i ka hoʻokō ʻana i nā kikoʻī o ka ʻoihana.
Hana ʻia kā mākou mau paipu mai ke kila A252 GRADE 2, kahi mea i ʻike ʻia no kona ikaika a me kona kūpaʻa. He kūpono loa kēia ʻano kila no nā noi e pili ana i nā hoʻonohonoho ʻana ma lalo o ka lepo kahi e koʻikoʻi ai ka paʻa o ka mea. Hoʻolālā ʻia ka paipu kila A252 GRADE 2 e kū i nā kūlana koʻikoʻi i ʻike pinepine ʻia i nā kaiapuni lalo, e lilo ia i koho kūpono no nā noi pipeline gas.
Ma keʻano he mea hilinaʻi hilinaʻi o ka paipu SSAW (Spiral Submerged Arc Welded), hōʻoia mākou i kā mākou huahana e hoʻokō i nā kūlana kiʻekiʻe loa. Hana ʻia kēlā me kēia puʻu paipu me ka hoʻohana ʻana i nā ʻenehana wiliwili holomua e hoʻonui ai i ka ikaika a me ka lōʻihi o ka mea. ʻIke ʻia kā mākou paipu SSAW no kāna mau ʻano mechanical maikaʻi loa a kūpono ia no nā ʻano noi like ʻole, me nā pipeline gas kūlohelohe ma lalo o ka honua. ʻO ke kaʻina hana wiliwili spiral ʻaʻole wale e hāʻawi i kahi hoʻolālā ikaika, akā hiki nō hoʻi i ka hana ʻana i nā lōʻihi lōʻihi, e hōʻemi ana i ka pono o nā hono a hoʻonui i ka pono holoʻokoʻa o ka hoʻonohonoho.

Nānā huahana
ʻAʻole ʻoi aku ka nui o ka phosphorus ma mua o 0.050% o ke kila.
ʻAe ʻia nā ʻano like ʻole i nā kaumaha a me nā ana
Pono e kaupaona ʻia kēlā me kēia lōʻihi o ka paipu paipu a ʻaʻole e ʻokoʻa kona kaumaha ma mua o 15% a i ʻole 5% ma lalo o kona kaumaha kumu, i helu ʻia me kona lōʻihi a me kona kaumaha no kēlā me kēia lōʻihi.
ʻAʻole e ʻokoʻa ke anawaena o waho ma mua o ±1% mai ka anawaena waho i koho ʻia
ʻAʻole ʻoi aku ka mānoanoa o ka pā ma kēlā me kēia wahi ma mua o 12.5% ma lalo o ka mānoanoa pā i kuhikuhi ʻia
Ka lōʻihi
Nā lōʻihi like ʻole: 16 a 25ft(4.88 a 7.62m)
ʻElua mau lōʻihi like ʻole: ma luna o 25ft a 35ft(7.62 a 10.67m)
Nā lōʻihi like ʻole: ʻae ʻia ka hoʻololi ʻana ±1in
Hoʻopau
E hoʻolako ʻia nā puʻu paipu me nā wēlau maʻemaʻe, a e wehe ʻia nā ʻōpala ma nā wēlau
Ke pau ka hopena o ka paipu i ʻōlelo ʻia he bevel, ʻo ka huina o 30 a 35 degere
Hoailona huahana
E hōʻailona ʻia kēlā me kēia lōʻihi o ka paipu paipu e ka stenciling, stamping, a i ʻole ka ʻōwili ʻia e hōʻike: ka inoa a i ʻole ka inoa o ka mea hana, ka helu wela, ke kaʻina hana, ke ʻano o ka hili helical, ke anawaena o waho, ka mānoanoa o ka paia, ka lōʻihi, a me ke kaumaha o kēlā me kēia ʻāpana lōʻihi, ka ʻōlelo kikoʻī a me ka papa.
ʻO kahi hiʻohiʻona koʻikoʻi o kā mākou mau puʻupuʻu ʻo ko lākou paona kaumaha. Ke kaupaona pono ʻia kēlā me kēia puʻu a mālama mākou i nā ʻae ʻana e hōʻoia i ka ʻokoʻa ʻole o ke kaumaha ma mua o 15% a i ʻole 5% o ke kaumaha theoretical. He mea koʻikoʻi kēia pololei no nā ʻenekinia a me nā mea ʻaelike e hilinaʻi nei i nā kikoʻī pololei no kā lākou papahana. Ma ka mālama ʻana i kēia mau paona kaumaha, kōkua mākou e hōʻoia i ka holo pono ʻana o ke kaʻina hana a me ka hoʻokō ʻana o ka hana o nā puʻu i nā kūlana i manaʻo ʻia.
ʻO kā mākou kūpaʻa i ka maikaʻi ma mua o ke kaʻina hana. Hoʻomaopopo mākou ʻo ka kūleʻa o kēlā me kēia papahana e pili ana i nā pipeline gas ma lalo o ka honua ma muli o ka hilinaʻi o nā mea i hoʻohana ʻia. No laila, hoʻokō mākou i nā loiloi mana maikaʻi i kēlā me kēia pae o ka hana. Hoʻolaʻa ʻia kā mākou hui loea e hōʻoia i kēlā me kēia puʻu e hoʻokō i nā kikoʻī kūpono a hiki ke hoʻohana koke ʻia ma ka lawe ʻana.
Ma waho aʻe o nā puʻu kiʻekiʻe, hāʻawi mākou i ka lawelawe a me ke kākoʻo maikaʻi loa. Loaʻa kā mākou hui ʻike e pane i nā nīnau āu e loaʻa ai, hāʻawi i ke alakaʻi ʻenehana, a kōkua iā ʻoe e koho i nā huahana kūpono no kāu mau pono kikoʻī. Haʻaheo mākou iā mākou iho i ke kūkulu ʻana i nā pilina lōʻihi me kā mākou mea kūʻai aku, me ka hōʻoia ʻana ʻaʻole lākou e loaʻa wale i kahi huahana papa mua, akā ke kākoʻo pū kekahi e pono ai lākou e hoʻopau pono i kā lākou papahana.
I ka hōʻuluʻuluʻana,ʻo kā mākou mau paipu paipu maikaʻi i hanaʻia mai ke kila A252 GRADE 2, i loaʻa ma o kā mākou lawelawe mea kūʻai paipu SSAW,ʻo ia ka hopena maikaʻi loa no kāu papahana pipeline gas ma lalo. Me kā mākou kūpaʻa i ka maikaʻi, ka pololei, a me ka ʻoluʻolu o ka mea kūʻai aku, hiki iā ʻoe ke hilinaʻi iā mākou e hāʻawi i nā mea āu e pono ai e hōʻoia i ka holomua a me ka palekana o kāu hoʻomohala ʻana. E koho i kā mākou mau paipu paipu no kahi hopena hilinaʻi, paʻa, a maikaʻi hoʻi i kāu mau pono kūkulu lalo.
