Iibholiti zamandla aphezulu: phi kwaye nini na ukuzisebenzisa

2026-05-25

Yintoni eyenza iBolt ibe namandla aphezulu?

Iibholiti zokuqina okuphezulu zichazwa ziiparamitha ezingundoqo ezintathu:

Amandla okuqina — owona mthwalo uphezulu ibholithi inokumelana nayo phambi kokwaphuka (kulinganiswa ngeMPa)
Amandla esivuno - umthwalo apho ibholithi iqala ukonakala ngokusisigxina
Umthwalo wobungqina - ukunyanzeliswa kwangaphambili okusetyenziswa ngexesha lofakelo ukudala amandla okudibanisa kwindawo

Iibholiti zamandla aphezulu ngokuqhelekileyo zenziwe ngentsimbi ye-carbon-medium okanye i-alloy steel kwaye zifumana unyango lobushushu (ukucima kunye nokufudumala) ukufezekisa iipropati ezifunekayo zomatshini. Iingubo zomphezulu - ezifana ne-zinc plating, i-Dacromet, okanye i-Luxubao-ifakwe ukunyusa ukuxhathisa ukubola ngaphandle kokubeka esichengeni amandla.

INYANISO ENGUNDOQO Iibholiti zeBanga le-10.9 zinamandla obunzima be-MPa eyi-1,000 - ngaphezu kwe-3 × yomelele kunomgangatho oqhelekileyo weBanga le-4.6.

Amacandelo angundoqo osetyenziso

Iibholiti zokuqina okuphezulu zisetyenziswa phantse kuwo onke amacandelo oshishino olunzima. Itheyibhile engezantsi ichaza ezona ndawo zixhaphakileyo zesicelo kunye neentlobo zesibophelelo esihambelanayo:

Ishishini / iCandelo	Usetyenziso oluqhelekileyo	Uhlobo lweBolt / Fastener
Intsimbi yoLwakhiwo kunye noKwakha	I-Beam-to-column uxhumano, iiplate zesiseko, iibholiti ze-anchor	I-hex bolt yokuqina okuphezulu (iBakala 8.8 / 10.9)

Intsimbi yoLwakhiwo kunye noKwakha

Ishishini lokwakha ngowona mthengi mkhulu weebholiti eziphezulu. Uqhagamshelo lwebholithi yolwakhiwo luthatha indawo yewelding yesiko kwi-beam-to-column joints, enikezela ngofakelo olukhawulezayo, uhlolo olulula, kunye nokuxhathisa okukhulu kwimithwalo yenyikima.

Iibholiti zeHex (iBanga lesi-8.8 / 10.9) — zisetyenziswa kuqhagamshelo oluxhathisa umzuzwana, iiankile zeepleyiti ezisisiseko, kunye neepleyiti zesplice
Iibholiti ze-anchor - zifakwe kwiziseko zekhonkrithi zokukhusela iikholomu zentsimbi yesakhiwo
Iibholiti ezinzima zehex ezinamandongomane - umgangatho we-AISC kunye ne-EN 1090-ehambelanayo noqhagamshelo lwesakhelo sentsimbi

PRO ICEBISO Ukudibanisa okubalulekileyo, sebenzisa rhoqo iibholiti ze-ASTM A325 okanye ze-A490 ezineewasha eziqinileyo kunye nezitshixo zetorque.

Iibhulorho & neZiseko zoLuntu

Ulwakhiwo lwebhulorho lufuna iziqhoboshi ezinokumelana nemithwalo ephilayo, ukwanda kobushushu, kunye namashumi eminyaka okuvezwa kokusingqongileyo. Iibholiti zezakhiwo eziphakamileyo zichazwe kwiikhowudi zebhulorho zamazwe ngamazwe ezibandakanya i-AASHTO, i-Eurocode 3, kunye nemigangatho ye-GB / T.

Iibholiti ze-Flange - qhagamshela amacandelo e-steel girder kwiibhulorho
Iibholiti ze-stud ezinamantongomane - iindawo ezikhuselekileyo zokwandisa kunye neendibano zeplate yokuthwala
Iibholiti ze-hex-coated-coated - ezichazwe kwizakhiwo zebhulorho ezingaselunxwemeni kunye ne-offshore ukuthintela ukubola.

Amandla omoya kunye nokuVeliswa koMbane

Iinqaba ze-injini yomoya zidityaniswe kusetyenziswa iibholithi ze-flange ezinobude obukhulu obunobubanzi obuphezulu-amaxesha amaninzi iBanga le-10.9 okanye i-12.9 - eziphantsi komthwalo wokudinwa komjikelo kubo bonke ubomi babo benkonzo yeminyaka engama-25. Ukuchaneka kokulayisha kwangaphambili kwebholt kubalulekile; iibholiti eziqiniswe ngaphantsi zibangela ukusilela kokudinwa kwenqaba, ngelixa iibholiti eziqiniswe kakhulu zinika umngcipheko.

Iibholiti ze-Tower flange (M36–M72, iBanga le-10.9) - esona sicelo sifunwa kakhulu sebholithi ephezulu kwicandelo lamandla avuselelweyo
Iibholiti ze-anchor zesiseko - qhagamshela isiseko senqaba kwisiseko semfumba yekhonkrithi
I-Nacelle kunye ne-rotor hub bolts - uxhulumaniso lwesakhiwo sangaphakathi kunye neemfuno ezingqongqo ze-torque

INQAKU LOKUGQIBELA I-Zinc-flake / i-Luxubao-coated bolts ikhethwa kwi-wind tower applications - ibonelela ngokumelana nokugqwesa okuphezulu kwaye ayina-hydrogen-embrittlement.

Oomatshini abaManzi kunye neZixhobo zoShishino

Oomatshini bokushicilela, izityuli, izixhobo zemigodi, kunye neebhokisi zegiya zamashishini zivelisa imithwalo eguquguqukayo egqithileyo efuna ukuchaneka kokuqina okuphezulu. Ukukhulula ibholithi koomatshini abajikelezayo kunokubangela ukusilela okuyintlekele kunye nexesha lokuncipha kwemveliso.

Izikrufu zentloko yesokethi (iBanga le-12.9) — zisetyenziswa kwiindawo ezivaliweyo apho ufikelelo oluqhelekileyo lwe-hex lungafumanekiyo
Iibholiti ze-Flange - zibonelela ngokuzimela kwaye zixhathise imikhosi yokucheba esecaleni kumatshini wokunyuka
Cwangcisa izikrufu kunye nezikrufu zegrub - iikhomponenti ezijikelezayo ezikhuselekileyo kwiishafti ngaphandle kweentloko eziveziweyo

I-oyile, igesi kunye nePetrochemical

Uqhagamshelo lwe-pipeline flange kunye nezigqubuthelo zenqanawa zoxinzelelo kwishishini leoli kunye negesi lisebenza phantsi koxinzelelo oluphezulu, amaqondo obushushu agqithisileyo, kunye nemithombo yeendaba eyonakalisayo. Izibophelelo kwezi ndawo kufuneka zihlangabezane nemigangatho ye-ASME B16.5 kunye ne-ASTM A193/A194.

I-ASTM A193 B7 stud bolts (Cr-Mo alloy steel) - umgangatho woshishino woqhagamshelwano oluphezulu lobushushu obuphezulu
I-2H i-hex nuts enzima (ASTM A194) - idityaniswe ne-B7 studs kwiiflange ezilinganiswe ngoxinzelelo
Iibholiti ze-Incoloy / super-alloy - ezichazwe kwiimeko zenkonzo ezonakalisayo okanye ezicryogenic

Ukukhuselwa koMhlwa kwiiBolts eziPhezulu zamandla

Ukonakala ngoyena nobangela uphambili wokusilela kwe-fasteners kwangaphambi kwexesha kwindawo yangaphandle nakwimizi-mveliso. Ukukhetha unyango olufanelekileyo lomhlaba luyimfuneko - ngakumbi kwiibholiti eziphezulu apho i-hydrogen embrittlement esuka kwi-electroplating iyingozi yokwenene ngaphezu kweBanga le-10.9.

I-Dacromet yokugqoka - i-water-based, i-chromate-free, i-480-1000 + h ukumelana netyuwa-spray; ikhuselekile kwiibholithi zeBakala 10.9/12.9
I-Luxubao (i-zinc-flake) i-coating - efana ne-Geomet / Delta-Tone; igqwesileyo kumandla omoya kunye nolwakhiwo olunzima
I-Hot-dip galvanizing — ilungele iBakala 8.8 nangaphantsi; akukhuthazwanga ngaphezu kweBanga le-10.9 ngenxa yomngcipheko we-hydrogen
I-Zinc electroplating - ukhetho lwezoqoqosho kwiindawo zangaphakathi okanye eziphantsi
Insimbi engenasici (A2-70 / A4-80) - i-corrosion-resistant ngokwemvelo; akukho ukutyabeka okongeziweyo okufunekayo

Kutheni ukhetha i-FUJINRUI High-Strength Fasteners?

Yenziwe kwi-ISO 898-1, ASTM A325/A490, kunye nemigangatho yeDIN 931/933
Uluhlu olupheleleyo lweengubo: I-Dacromet, iRuspert, i-zinc-plated, i-hot-dip galvanized, iphosphate
Ubungakanani ukusuka ku-M6 ukuya kwi-M64, amandla amabakala 8.8 / 10.9 / 12.9
Izatifikethi zokuvavanya koomatshini zomntu wesithathu ziyafumaneka (ukuqina, ukuqina, ukutshiza ityuwa)
Amaxabiso akhuphisanayo namaxesha okukhokelela ngokukhawuleza kwi-OEM eninzi kunye neeodolo zeprojekthi
