Flanges yog cov khoom uas txuas cov ncej rau ib leeg, feem ntau yog siv los txuas cov yeeb nkab kawg. Yog li ntawd, lawv tseem siv dav hauv cov khoom siv txhua hnub. Txawm li cas los xij, vim muaj cov duab sib txawv ntawm txhua cov yeeb nkab kawg, yuav tsum muaj qee yam txheej txheem thaum xaiv ib lub taub hau bolts. Tom ntej no, tus editor yuav qhia koj txog yuav ua li cas xaiv ib lub taub hau bolts raws li flanges.
Vim yog siv tib lub taub hau bolts rau flanges, hexagonal bolts thiab ceev feem ntau yog siv rau flanges. Hexagons feem ntau siv thiab tuaj yeem muab faib ua ob hom: ib qho chamfered thiab ob chav chamfered. Cov ncauj lus kom ntxaws yog raws li nram no: bolts tau muab faib ua ib lub taub hau bolts thiab ob lub taub hau bolts raws li lawv cov tsos. Ib lub taub hau bolts tsuas yog muaj cov xov machined ntawm ib kawg ntawm cov ntsia hlau, thaum lwm qhov kawg yog lub taub hau ntsia hlau txuas nrog lub hau ntsia hlau.
Ib lub taub hau bolts rau flanges feem ntau yog hexagonal bolts. Ob qhov kawg ntawm ob lub taub hau ntsia liaj qhov rooj yog threaded thiab muaj ib tug cylindrical zoo. Thaum lub zog nruj yog siab, ib lub taub hau bolts yog nquag tawg ntawm qhov sib koom ntawm cov ntsia hlau thiab lub taub hau ntsia hlau, yog li lawv tsis tuaj yeem siv rau nruab nrab thiab siab flanges. Muab ob npaug rau taub hau bolts tsis tau tsuas yog siv rau nruab nrab thiab siab siab flanges, tab sis kuj pab txhawb ob-sided zawm.
Bolts tau muab faib ua bolts ntxhib, semi refined bolts, thiab refined bolts raws li lawv txoj kev tsim khoom. Tsuas yog cov threaded ib feem, qhov saum npoo ntawm lwm qhov ntawm cov ntsia liaj qhov rooj ntxhib tsis nres precision machining, uas ua rau muaj qhov ntxhib ntxhib ntxhib zoo. Bolts feem ntau yog ua los ntawm cov pa roj carbon steel, uas tsis tau txais lub zog tensile siab. Semi refined thiab refined bolts yuav tsum tau nres los ntawm kev ua, thiab qee qhov tseem yuav tsum tau nres kev kho cua sov. Lawv feem ntau yog siv rau hauv kev tsim cov pa roj carbon zoo lossis hlau alloy, yog li lawv muaj lub zog tensile siab thiab kub ua haujlwm.
