10. Nā Pōmaikaʻi o ke kila Womic a me nā nīnau pinepine - Paipu kila ASTM A572 GR.50 SSAW

No ke aha e hui pū ai me Womic Steel no ka paipu kila ASTM A572 GR.50 SSAW?

Ka nui piha o nā nui:ʻO ke kaʻina hana SSAW e uhi ana i 219mm a i 3,000mm OD, ka mānoanoa o ka paia a hiki i 25.4mm, ka lōʻihi a hiki i 60m no nā papahana alahaka a me nā papahana kūkulu.

Ka Manaʻo Kiʻekiʻe:ʻIke kūikawā i nā hoʻohana paipu kila haʻahaʻa ikaika kiʻekiʻe no nā alahaka, nā hale, a me nā hale ʻoihana kaumaha.

ʻIke loea HSLA:Ka hoʻomaopopo hohonu ʻana i nā waiwai o ka mea ASTM A572 GR.50, nā koi kuʻihao, a me nā noʻonoʻo hana ʻana no ke kila ikaika kiʻekiʻe.

Nā lawelawe waiwai i hoʻohui ʻia:Ke beveling ʻana o ka hopena, ka ʻoki ʻana i ka hopena maʻemaʻe, ka uhi pale (primer, galvanizing, FBE, 3LPE), a me ka ʻōwili anti-corrosion.

Ka hiki ke lōʻihi:A hiki i ka 60m ka lōʻihi hoʻokahi no nā kaʻa o ke alahaka a me nā noi kūkulu lōʻihi, e hōʻemi ana i nā koi splicing kahua.

Hoʻokūkū Logistics:ʻO ka hui pū ʻana me nā mea hoʻouna ukana honua a me nā loea ukana papahana e hōʻoiaʻiʻo ana i ka hoʻouka maikaʻi ʻana a me ka hoʻouna ʻana ma ka honua holoʻokoʻa me ke kumukūʻai kūpono.

Palapala Hoʻopihapiha:Nā Palapala Hōʻoia Hoʻāʻo Wili Piha (EN 10204 ʻAno 2.2, 3.1, a i ʻole 3.2), nā hōʻike NDT, nā hōʻike ana, a me nā palapala hiki ke hahai ʻia i hāʻawi ʻia no kēlā me kēia ukana.

E koho iā Womic Steel Group ma ke ʻano he hoa hilinaʻi no nā paipu kila ikaika kiʻekiʻe ASTM A572 GR.50 SSAW no nā papahana alahaka, kūkulu hale, a me nā ʻoihana kaumaha ma ka honua holoʻokoʻa. Welina mai e nīnau!

Nā Nīnau i Nīnau Pinepine ʻia (FAQ) - Paipu Kila ASTM A572 GR.50 SSAW

Q: He aha ka ʻokoʻa ma waena o ke kila ASTM A572 GR.50 a me ke kila A36?

A: ʻO ka ikaika hua liʻiliʻi loa o ASTM A572 GR.50 he 345 MPa (50,000 psi), ʻoiai ʻo A36 he 250 MPa (36,000 psi). Hāʻawi ʻo GR.50 ma kahi o 38% ka ikaika hua kiʻekiʻe aʻe, e ʻae ana i nā ʻano māmā a me nā nui ʻāpana i hoʻemi ʻia. Ua hoʻomaikaʻi pū ʻia ʻo GR.50 i ke kūpaʻa ʻana i ka palaho lewa ma muli o kona ʻano HSLA.

Q: Hiki ke hoʻopili ʻia ʻo ASTM A572 GR.50 me ka hoʻohana ʻana i nā kaʻina hana maʻamau?

A: ʻAe, loaʻa iā ASTM A572 GR.50 ka hiki ke hoʻopili maikaʻi loa. Eia nō naʻe, ma muli o kona ikaika kiʻekiʻe a me ka nui o ka metala (columbium a me vanadium), ua ʻōlelo ʻia nā kaʻina hana hoʻopili haʻahaʻa-hauwai. Pono paha ka hoʻomehana mua ʻana no nā ʻāpana mānoanoa. Hiki iā Womic Steel ke hāʻawi i nā ʻōlelo aʻoaʻo no ke kaʻina hana hoʻopili ma ke noi ʻana.

Q: He aha ka ʻokoʻa ma waena o ASTM A572 GR.50 a me ASTM A992?

A: ʻO ASTM A572 GR.50 kahi kikoʻī maʻamau no nā papa kila HSLA, nā ʻano, a me nā kaola. ʻO ASTM A992 no nā kaola flange ākea a me nā ʻano kūkulu no ka hoʻopili ʻana i nā hale. Loaʻa i nā mea ʻelua ka ikaika hua like (345-450 MPa), akā ʻoi aku ka paʻa o nā kaohi o A992 i nā waiwai mea no nā noi seismic.

Q: He aha ka lōʻihi hoʻokahi no ka paipu kila ASTM A572 GR.50 SSAW?

A: ʻO nā lōʻihi maʻamau he 6m, 12m, a me 18m. Loaʻa nā lōʻihi maʻamau a hiki i ka 60m ma muli o ke anawaena a me ka mānoanoa o ka paia. He kūpono nā lōʻihi keu no nā girders alahaka a me nā noi kūkulu lōʻihi.

Q: He aha nā koho hoʻopau ʻili i loaʻa no nā noi alahaka?

A: No nā noi alahaka, hāʻawi mākou i ka uhi primer, ka galvanizing hot dip, a i ʻole nā ʻōnaehana anti-corrosion kūikawā (FBE, 3LPE, a i ʻole nā uhi epoxy). Loaʻa pū ke kila weathering (ASTM A588) no nā noi alahaka e koi ana i ke kūpaʻa ʻana i ka corrosion lewa me ka ʻole o ka pena ʻana.

Q: Hiki iā ʻoe ke hoʻolako i ka paipu ASTM A572 GR.50 me ka nānā ʻana o ka ʻaoʻao ʻekolu?

A: ʻAe. Hoʻomaʻamaʻa mākou i nā nānā ʻana e SGS, BV, TÜV, DNV, ABS, LR, a i ʻole kekahi ʻelele i koho ʻia e ka mea kūʻai aku i ka wā o ka hana ʻana a ma mua o ka hoʻouna ʻana. 3.2 hāʻawi mau ʻia nā palapala hōʻoia nānā ma ke noi.

Q: He aha nā palapala i hāʻawi ʻia me kēlā me kēia ukana?

A: Palapala Hoʻāʻo Wili (EN 10204 ʻAno 3.1), Hōʻike Nānā Ana, Nā Hōʻike UT, Nā Hōʻike RT (inā i kuhikuhi ʻia), Palapala Traceability, Papa Inoa Hoʻopili, Bila Kūʻai, a me ka Palapala Hoʻomaka.
