Mea Hoʻohui o A671 CC65 Paipu
Hana ʻia ka paipu ASTM A671 CC65 i ke kila kalapona, kahi mea maʻalahi a hoʻohana nui ʻia i ka hana ʻana i nā paipu ʻoihana. ʻO ka "CC" ma ka papa inoa e kū nei no "Carbon Steel," e hōʻike ana i kāna haku mele mua. ʻO ka helu "65" e pili ana i ka palena liʻiliʻi o ka ikaika tensile o 65,000 psi (448 MPa) no kēia papa.
ʻO ke kila kalapona kahi huila o ka hao a me ke kalapona, me ka maʻamau kalapona mai 0.05% a 0.30% no Nā paipu ASTM A671. Hāʻawi kēia haku mele i kahi kaulike o ka ikaika, ductility, a me ka weldability, e kūpono ai no nā noi ʻoihana like ʻole. Hoʻoponopono maikaʻi ʻia nā ʻano kalapona kūikawā a me nā mea hoʻohui ʻē aʻe e hoʻokō i nā pono mechanical i makemake ʻia a me nā ʻano hana.
Huina Kemika o ASTM A671 CC65
Hoʻoponopono maikaʻi ʻia ka hui kemika o ka paipu ASTM A671 CC65 e hōʻoia i ka hana mau a me ka maikaʻi. ʻOiai ʻokoʻa iki nā pākēneka pololei i loko o nā pae i ʻae ʻia, ʻo ka haku melemele maʻamau e komo pū ana:
- Kalapona (C): 0.18% - 0.23%
- Manganese (Mn): 0.80% - 1.20%
- ʻO Phosphorus (P): 0.025% ka nui
- Sulfur (S): 0.025% ka nui
- Silikino (Si): 0.15% - 0.30%
- Nikela (Ni): 0.40% ka nui
- Chromium (Cr): 0.30% ka nui
- Molybdenum (Mo): 0.12% ka nui
- Ke keleawe (Cu): 0.40% ka nui
- Vanadium (V): 0.08% ka nui
- Kolumbium (Cb): 0.02% ka nui
He kuleana ko kēlā me kēia mea i loko o kēia haku mele i ka hoʻoholo ʻana i nā waiwai o ka paipu:
- Carbon: Hāʻawi i ka ikaika a me ka paʻakikī
- Manganese: Hoʻonui i ka paʻakikī a me ka ikaika
- Silicon: Ke hana nei ma ke ʻano he deoxidizer a hoʻomaikaʻi i ka ikaika
- Nickel, Chromium, a me Molybdenum: Hoʻonui i ka pale ʻana i ka corrosion a me nā waiwai mechanical
- ʻO Vanadium a me Columbium: Hoʻomaʻemaʻe i ka hoʻolālā palaoa a hoʻomaikaʻi i ka ikaika
ʻO ka mana pololei o kēia mau mea e hōʻoia i kēlā Nā paipu ASTM A671 CC65 e hoʻokō i nā pono mechanical pono a me nā kūlana hana no kā lākou mau noi i manaʻo ʻia.
Ka hopena o nā mea ma luna o nā waiwai Mechanical o A671 CC65
ʻO ka haku mele ʻana o ASTM A671 CC65 paipu hoʻopili pololei i kona mau waiwai mechanical, kūpono ia no nā ʻano hana ʻenehana. ʻO kekahi mau waiwai mechanical nui i hoʻopili ʻia e ka haku mele:
- Ka ikaika tensile: Loaʻa ka ikaika tensile haʻahaʻa o 65,000 psi (448 MPa) ma o ke koena akahele o ka ʻike kalapona a me nā mea hoʻohui. ʻO kēia ikaika ka mea e hiki ai i ka paipu ke kū i nā kaomi kiʻekiʻe o loko a me nā ukana waho.
- ʻO ka ikaika o ka hua: ʻo nā paipu papa CC65 ka liʻiliʻi loa o 35,000 psi (241 MPa). He mea koʻikoʻi kēia waiwai no ka hoʻoholo ʻana i ka hiki o ka paipu ke pale i ka deformation mau ma lalo o ke kaumaha.
- Ductility: ʻO ka hui kaulike e hōʻoia i ka ductility maikaʻi, e ʻae i ka paipu e hana i kekahi deformation me ka ʻole o ka haki. He mea koʻikoʻi kēia i nā noi kahi e ʻike ai ka paipu i ka piʻo ʻana a i ʻole ka wili.
- 'O'ole'a: 'O ka haku mele 'ana i ka paipu, 'o ia kona hiki ke komo i ka ikehu ma mua o ka ha'i 'ana. Pono kēia no nā noi ma nā wahi haʻahaʻa haʻahaʻa a i ʻole kahi e koi ʻia ai ke kūpaʻa hopena.
- Weldability: ʻO ka ʻike kalapona a me ka alloy o ka mea paipu A671 CC65 e hōʻoia i ka weldability maikaʻi loa, he mea koʻikoʻi no ka hui ʻana i nā ʻāpana paipu a me ka hana ʻana i nā ʻōnaehana paipu paʻakikī.
- Kū'ē Kū'ē: ʻOiai ʻaʻole e like me ka pale ʻana i ka corrosion e like me kekahi mau māka kila kila, ʻo ka haku mele ʻana o A671 CC65 e hāʻawi i ke kūpaʻa kūpono i ka ʻino o ka lewa a me kekahi mau kaiapuni kemika, ʻoi aku ka maikaʻi ke uhi ʻia a mālama ʻia paha.
Hoʻohana kēia mau mea mechanical i ka paipu ASTM A671 CC65 i kūpono no ka nui o nā noi, ʻo ia hoʻi i nā ʻoihana e koi ana i nā hoʻonā paipu kūpaʻa a paʻa no ke kaomi haʻahaʻa a me nā kūlana wela.
Nā ʻoihana e hoʻohana mau nei i ka paipu A671 CC65
ASTM A671 CC65 paipu loaʻa nā noi i nā ʻoihana like ʻole ma muli o kāna hana hilinaʻi, ikaika, a me ka versatility. ʻO kekahi o nā ʻoihana nui e hoʻohana mau nei i kēia ʻano paipu:

ʻO ka hoʻohana nui ʻana o ka paipu ASTM A671 CC65 ma waena o kēia mau ʻoihana he mea hōʻike i kona hilinaʻi, lōʻihi, a me ka versatility. ʻO kona hiki ke mālama i nā kaomi haʻahaʻa a me nā mahana, i hui pū ʻia me ka weldability maikaʻi a me ka pale ʻana i ka corrosion, lilo ia i koho kaulana no nā noi paipu ʻoihana.
Hoʻokaʻaʻike i ka hui Longma
ʻO ka paipu ASTM A671 CC65, me kāna mea i hoʻonohonoho pono ʻia a me nā waiwai mechanical maikaʻi, ke hoʻomau nei i kahi koho koho no nā noi ʻoihana he nui. ʻO kona versatility, ikaika, a me ka hilinaʻi e lilo ia i mea koho maikaʻi loa no nā papahana e koi ana i nā hopena paipu ikaika.
Inā ʻoe e ʻimi nei nā paipu ASTM A671 kiʻekiʻe no kāu mau pono ʻoihana, aia ʻo Longma Group e kōkua iā ʻoe. Ma ke ʻano he mea nui o Kina e hana ai i ka paipu kila ERW/LSAW mai ka makahiki 2003, ʻoihana mākou i ka hana ʻana i nā paipu kila nui-diameter, pā mānoanoa, ʻaoʻao ʻelua, sub-arc-seam. ʻO kā mākou akamai a me kā mākou kūpaʻa i ka maikaʻi e hōʻoia e loaʻa iā ʻoe nā huahana maikaʻi loa no kāu mau koi kikoʻī.
Mai hoʻokaʻulua e kelepona mai iā mākou no kāu mau pono paipu A671 a i ʻole nā ʻōnaehana paipu ʻoihana ʻē aʻe. E kelepona iā mākou i kēia lā ma info@longma-group.com e kūkākūkā pehea e hiki ai iā mākou ke kākoʻo i kāu papahana me kā mākou huahana kiʻekiʻe a me ke alakaʻi alakaʻi. E hana pū kākou e kūkulu i ka wā e hiki mai ana i ʻoi aku ka ikaika a me ka maikaʻi no kāu ʻoihana.
