Nta thiab Cov txiaj ntsig
Flange Bolt Din 6921 Cl 8.8 yog lub zog muaj zog uas feem ntau siv rau hauv cov ntawv siv hnyav.Nws yog ib hom flange ntsia liaj qhov rooj uas tsim los nrog lub tshuab ntxhua khaub ncaws zoo li flange ntawm lub hauv paus, uas muab kev txhawb nqa ntxiv thiab tiv thaiv cov ntsia liaj qhov rooj los ntawm loosening vim kev co lossis torque.Lub ntsia liaj qhov rooj nta lub taub hau hexagon uas tso cai rau kev txhim kho yooj yim thiab tshem tawm siv cov ciaj ntswj lossis pliers.
Ua raws li tus qauv DIN 6921, qhov flange bolt no ua tau raws li cov kev cai tshwj xeeb rau cov xov loj, ntev, thiab suab, nrog rau cov khoom siv thiab cov khoom siv kho tshuab.Nws yog tsim los ntawm nruab nrab carbon steel alloyed nrog cov ntsiab lus xws li chromium, molybdenum, thiab vanadium, uas txhim kho nws lub zog thiab kav ntev.Lub ntsia liaj qhov rooj kuj yog coated nrog ib txheej tiv thaiv, xws li zinc plating los yog galvanization, uas tiv thaiv corrosion thiab xeb tsim.
Qhov no flange ntsia liaj qhov rooj muaj chav kawm 8.8, qhia tias nws lub zog tensile tsawg kawg yog 800 N / mm2 thiab tawm lub zog ntawm yam tsawg kawg nkaus 640 N / mm2.Qhov no ua rau nws tsim nyog siv rau hauv cov ntawv thov uas yuav tsum muaj lub zog clamping siab thiab ua rau qaug zog, cuam tshuam, thiab sab nraud.Nws yog feem ntau siv hauv tsheb, kev tsim kho, tshuab, thiab kev siv khoom siv.
Qhov ntev ntawm lub ntsia liaj qhov rooj sib txawv nyob ntawm seb qhov kev thov tshwj xeeb, xws li 10 hli mus rau 100 hli lossis ntau dua.Cov xov loj yog nyob ntawm M6 txog M30 lossis loj dua, nrog cov suab sib txawv muaj xws li nplua, ntxhib, thiab ntxhib ntxiv.Lub taub hau hexagon tuaj yeem yog flanged lossis chamfered thiab kuj tseem tuaj yeem muaj qhov chaw so lossis ib qho cim los qhia cov chaw tsim khoom lossis qib.
Zuag qhia tag nrho, Flange Bolt Din 6921 Cl 8.8 yog ib qho kev txhim khu kev qha thiab ruaj khov kho uas muab lub zog zoo, ruaj khov, thiab tiv thaiv corrosion.Nws cov qauv tsim tau zoo thiab raug tsim ua kom pom kev ua tau zoo thiab kev nyab xeeb hauv ntau yam kev siv hnyav.
