Nā Bolts kiʻekiʻe: kahi a me ka manawa e hoʻohana ai iā lākou 

Ke kila a me ke kūkulu ʻana

ʻO kaʻoihana kūkulu hale ka mea kūʻai nui loa i nā bolts kiʻekiʻe. Hoʻololi nā hoʻohui bolt kūkulu i ka wili kuʻuna ma nā hui kuʻuna-a-kolume, hāʻawi ʻoi aku ka wikiwiki o ka hoʻokomo ʻana, ʻoi aku ka maʻalahi o ka nānā ʻana, a ʻoi aku ka pale ʻana i nā haʻahaʻa seismic.

• Hex bolts (Grade 8.8 / 10.9) — hoʻohana ʻia i nā pilina kūʻē i ka manawa, nā heleuma papa kumu, a me nā papa splice
• ʻO nā wili heleuma - hoʻokomo ʻia i loko o nā kumu paʻa no ka hoʻopaʻa ʻana i nā kolamu kila
• ʻO nā bolts hex kaumaha me nā nati - maʻamau no ka AISC a me EN 1090-compliant steel frame connections

KUMU MANAO  No nā pilina paheʻe, e hoʻohana mau i nā bolts ASTM A325 a i ʻole A490 me nā mea holoi paʻa a me nā wili torque calibrated.

Nā Alahaka & ʻOihana Kivila

Pono ke kūkulu ʻana i ke alahaka i nā mea hoʻopaʻa hiki ke kū i nā ukana ola ikaika, ka hoʻonui ʻana i ka wela, a me nā makahiki o ka ʻike kaiapuni. Hōʻike ʻia nā bolts structural kiʻekiʻe i nā code alahaka honua me nā kūlana AASHTO, Eurocode 3, a me GB/T.

• ʻO nā wili flange - hoʻohui i nā ʻāpana apo kila ma nā alahaka
• ʻO nā bolts me nā nati - hoʻopaʻa paʻa i nā hui hoʻonui a me nā hui pā
• ʻO nā bolts hex i uhi ʻia ʻo Dacromet - i kuhikuhi ʻia no nā hale alahaka kahakai a me waho e pale ai i ka ʻino.

Imi makani a me ka mana

Hoʻākoakoa ʻia nā hale kiaʻi turbine makani me ka hoʻohana ʻana i nā bolts flange ikaika kiʻekiʻe - pinepine ʻo Grade 10.9 a i ʻole 12.9 - i hoʻokau ʻia i nā ukana luhi cyclic i ko lākou ola lawelawe 25 makahiki. He mea koʻikoʻi ka pololei preload Bolt; ʻO nā bol i hoʻopaʻa ʻole ʻia ke kumu i ka pau ʻole o ka luhi o ka hale kiaʻi, ʻoiai ʻo nā kī i hoʻopaʻa ʻia e hiki ke hāʻawi.

• ʻO nā bolts flange Tower (M36–M72, Papa 10.9) - ka noi koi ikaika kiʻekiʻe loa i ka ʻāpana ikehu hou.
• Nā wili heleuma hoʻokumu - hoʻohui i ke kumu hale kiaʻi i ke kumu o ka puʻu kulu
• Nacelle a me nā rotor hub bolts - nā pilina o loko me nā koi torque koʻikoʻi

OLELO HOOLAHA  ʻOi ʻia nā bolts Zinc-flake / Luxubao-coated no nā noi hale kiaʻi makani - hāʻawi lākou i ke kūpaʻa ʻoi aku ka maikaʻi a me ka hydrogen-embrittlement-free.

Mekini Kaumaha & Lako Hana Hana

ʻO nā mīkini paʻi, nā mea hoʻoheheʻe, nā lako mining, a me nā pahu hana ʻoihana e hoʻoulu i nā ukana ikaika e koi ai i nā mea hoʻopaʻa ikaika kiʻekiʻe. ʻO ka wehe ʻana o ka Bolt i nā mīkini wili hiki ke hōʻeha i ka pōʻino a me ka manawa hana.

• ʻO nā ʻoki poʻo poʻo kumu (Papa 12.9) — hoʻohana ʻia i nā wahi paʻa kahi i loaʻa ʻole ai ke komo hex maʻamau
• ʻO nā bolts flange - hāʻawi i ka hilinaʻi ponoʻī a pale aku i nā ikaika ʻoki ʻaoʻao i nā puʻu mīkini
• E hoʻonoho i nā wili a me nā ʻūlū grub - hoʻopaʻa i nā ʻāpana wili i nā kumu me ke poʻo ʻole

Aila, Gas & Petrochemical

ʻO nā pilina flange paipu a me nā uhi moku i loko o ka ʻoihana ʻaila a me ke kinoea e hana ana ma lalo o ke kaomi kiʻekiʻe, ka wela wela, a me ka media corrosive. Pono nā mea paʻa i kēia mau kaiapuni e hoʻokō i nā kūlana ASME B16.5 a me ASTM A193/A194.

• ASTM A193 B7 stud bolts (Cr-Mo alloy steel) - ke kūlana ʻoihana no nā pilina flange wela kiʻekiʻe.
• 2H nati hex kaumaha (ASTM A194) — hui pū ʻia me nā studs B7 no nā flanges i helu ʻia ke kaomi.
• ʻO nā bolts Incoloy / super-alloy — i kuhikuhi ʻia no nā kūlana lawelawe ʻino a cryogenic

Hoʻopaʻa ʻino no nā Bolts ikaika kiʻekiʻe

ʻO Corrosion ke kumu nui o ka hāʻule ʻana o ka mea hoʻopaʻa paʻa mua i nā wahi o waho a me nā ʻoihana. He mea nui ke koho ʻana i ka lāʻau lapaʻau kūpono - ʻoi aku ka nui o nā bolts ikaika kahi i pilikia maoli ai ka hoʻoheheʻe ʻana o ka hydrogen mai ka electroplating ma luna o ka Papa 10.9.

• ʻO ka uhi ʻana o Dacromet - pili wai, chromate-free, 480-1000+ h ka paʻakai paʻakai; palekana no nā bolts Grade 10.9/12.9
• Luxubao (zinc-flake) coating - like me Geomet/Delta-Tone; maikaʻi loa no ka makani makani a me ka hana kaumaha
• ʻO ka galvanizing wela - kūpono no ka Papa 8.8 a ma lalo; ʻAʻole ʻōlelo ʻia ma luna o ka Papa 10.9 ma muli o ka pilikia hydrogen
• Zinc electroplating — koho waiwai no nā wahi i loko a i ʻole ka haʻahaʻa haʻahaʻa
• Ke kila kila (A2-70 / A4-80) — kū i ka corrosion; ʻaʻole pono ka uhi ʻana

No ke aha e koho ai ʻo FUJINRUI i nā mea hoʻopaʻa ikaika kiʻekiʻe?

• Hana ʻia i ka ISO 898-1, ASTM A325/A490, a me DIN 931/933 maʻamau
• ʻO nā ʻāpana piha piha: Dacromet, Ruspert, zinc-plated, hot-dip galvanized, phosphate
• Nui mai M6 a M64, nā māka ikaika 8.8 / 10.9 / 12.9
• Loaʻa nā palapala hoʻāʻo mechanical ʻaoʻao ʻekolu (tensile, hardness, salt-spray)
• Ke kumu kūʻai hoʻokūkū me nā manawa alakaʻi wikiwiki no ka OEM nui a me nā kauoha papahana
