Kaomi i ka pihi ma ka ʻākau
1. Ke kūkulu ʻana i nā ʻōnaehana kūkulu
Nā hale kiʻekiʻe a me nā hale kūʻai
Nā kiʻikuhi kūkulu kila no nā hale hana ʻoihana a me nā hale kūʻai
Nā kolamu, nā kaola, a me nā ʻōnaehana kākoʻo
2. Nā Papahana Hana Kūkulu
Nā alahaka (nā kaola, nā ʻano hoʻopaʻa, a me nā ʻāpana papahele)
Nā hoʻololi alaloa a me nā viaducts
Nā kikowaena a me nā kahua kaʻaahi kūlanakauhale
3. Nā ʻāpana kūkulu kila
Nā kukuna H a me nā kukuna I i hoʻopaʻa ʻia

1) Keʻena Lālā - kākoʻo ʻōlelo Paniolo, kōkua hoʻomaʻemaʻe dute, a pēlā aku.
2) Ma luna o 5,000 tons o ka waihona i loko o ka waihona, me nā ʻano nui like ʻole
3) Nānā ʻia e nā hui mana e like me CCIC, SGS, BV, a me TUV, me ka hoʻopili ʻana i ke kai maʻamau
Ukana Nui
Kūpono no nā ukana he nui. Hiki ke kau pololei ʻia nā ʻōwili ma luna o ka moku a i ʻole e hoʻomoe ʻia. Pono e kau ʻia nā moena anti-shell ma lalo a me ka ʻili o nā ʻōwili. Pono e hoʻokaʻawale ʻia nā ʻōwili e nā ʻāpana lāʻau a i ʻole ke kaula a pale ʻia mai ka makani a me ka ua me nā tarpaulins a i ʻole ka ʻaila pale popo.
Nā Pōmaikaʻi: Ka nui o ka ukana, ke kumu kūʻai haʻahaʻa.
Hoʻomaopopo: Pono nā lako hāpai kūikawā. Pono e pale ʻia ka condensation a i ʻole ka hōʻino ʻana o ka ʻili i ka wā e lawe ʻia ai.
Ukana i hoʻopaʻa ʻia i loko o nā ipu
Kūpono no nā ukana liʻiliʻi a waena. Hoʻopili ʻia nā ʻōwili pākahi a mālama ʻia no ka pale ʻana i ka wai a me ka pale ʻana i ka popo; hiki ke waiho ʻia nā mea hoʻomaloʻo i loko o ka pahu.
Nā Pōmaikaʻi: Hāʻawi i ka palekana maikaʻi aʻe, maʻalahi e lawelawe.
Nā hemahema: Ke kumukūʻai kiʻekiʻe, hoʻemi ʻia ka mana o ka ipu.
Q1: He aha nā hoʻohana o ke kila ASTM A992?
Hoʻohana nui ʻia ke kila ASTM A992 i nā hana kūkulu e like me nā mōlina hale a me nā ʻano hana, nā hale hana ʻoihana, a me ka hana ʻana i nā ʻano hana kila kaumaha. He kūpono loa ia no ka hoʻoheheʻe ʻana i nā H-beams a me nā I-beams.
Q2: He aha nā pono o ke kila ASTM A992?
He ikaika kiʻekiʻe ko ke kila ASTM A992, ductility maikaʻi, weldability maikaʻi loa, a me nā waiwai paʻa, e maʻalahi ai ke kū i nā ukana a he koho kūpono no ke kila kūkulu e hali ana i ka ukana.
Q3: Hiki iaʻu ke hoʻoheheʻe a hana i ke kila ASTM A992?
ʻAe. Ua hoʻolālā kūikawā ʻia ke kila A992 me ka hiki ke hoʻopili maikaʻi loa, e hōʻoiaʻiʻo ana i ka hoʻopili wikiwiki, ikaika, a hilinaʻi hoʻi i ka wā o ke kūkulu ʻana i nā hale, me ke kōkua pū ʻana i ka hoʻēmi ʻana i ka manawa hana.
Q4: ʻO wai nā ʻoihana e hoʻohana ana i nā wili kila ʻōwili wela ASTM A992?
He nui nā noi o nā wili kila ASTM A 992 i ka ʻoihana, ʻoi aku hoʻi i ke kūkulu ʻana, nā ʻoihana (nā alahaka a me ka halihali kaʻaahi), ka hana ʻana i nā lako ʻoihana, nā hale kūʻai, a me nā papahana ikehu (e like me ka mana a me nā petrochemicals), kahi i nui ai ke koi.
Q5: He aha kāu mau huaʻōlelo hoʻolako maʻamau a me ka hoʻopili ʻana i waho?
ʻO ka ʻōpala hoʻokuʻu aku maʻamau e komo pū ana me: 1) Ka hoʻopili ʻana i ka wai e pili ana i ka laulā a me ka mānoanoa o ke kila; 2) Ka hoʻopili ʻana i ka ʻaila pale popo (e like me nā koi o ka mea kūʻai aku); 3) Hoʻoikaika me nā pallets lāʻau a i ʻole nā kiʻi kila. ʻO kēia ka mea e maʻalahi ai ka hoʻouna ʻana i nā ipu a me nā ukana nui.
