F900 Iron Manhole Npog

F900 Ductile Iron Manhole Npog yog ib qho ultra-siab-load infrastructure tivthaiv tsim los rau hnyav heev- lub luag haujlwm scenarios. Ua los ntawm cov hlau ductile- ua tiav nrog cov nodularizing cov neeg ua haujlwm los tsim cov qauv graphite kheej kheej- nws muab qhov zoo dua tensile lub zog, toughness, thiab corrosion tsis kam tshaj li cov cam khwb cia hlau zoo tib yam, ua kom ntev - lub sij hawm stability nyob rau hauv hnyav hnyav.
"F900" sawv cev rau nws cov chav kawm load, ua raws li European EN 124 tus qauv. Nws tuaj yeem tiv taus txog li 900 KN (sib npaug rau 90 tons) ntawm ntsug siab, ua rau nws haum rau cov xwm txheej nrog super- tsheb loj. Nws cov txiaj ntsig tseem ceeb suav nrog kev tiv thaiv -kev daws teeb meem (nruj haum nrog txoj hauv kev kom tsis txhob muaj kev sib tsoo), tiv thaiv - plam (Ntau dua lossis sib npaug rau 70 PSRV, txheeb xyuas los ntawm kev sim kev tshaj lij), thiab suab nrov tsawg (txo cov suab nrov nrov).

Cov chaw nres nkoj loj & cov khoom thauj hnyav: Rau txoj kab uas 100 tuj + thawv tsheb thauj khoom lossis cov tsheb thauj khoom loj ua haujlwm nquag;
Tshav dav hlau apron & runway nkag txoj kev: Enduring lub load ntawm aircraft tugs thiab hnyav tu tsheb;
Mining & heavy industrial zones: Resisting cuam tshuam los ntawm cov tsheb loj ore thiab corrosion los ntawm cov khoom seem;
Cov chaw tshwj xeeb engineering: xws li thaj chaw tsim kho rau cov txuas hniav loj, qhov av, lossis cov chaw ua haujlwm hnyav (xws li kev thauj khoom ntawm crawler cranes thiab tsheb thauj khoom hnyav).
​
Nrog rau nws sab saum toj -tier load-cov kabmob muaj peev xwm thiab kev ua tau zoo, F900 Cov Hlau Hlau Manhole Npog muab kev tiv thaiv txhim khu kev qha rau ultra- siab-load infrastructure, dhau los ua qhov kev xaiv tseem ceeb rau tej yaam num uas yuav tsum tau muaj zog heev thiab siab ua haujlwm.

Kev Ntsuam Xyuas Kev Pom Zoo: Txheeb xyuas qhov tsis xws luag ntawm qhov chaw (kab, qhov pores, xuab zeb qhov) nrog cov iav tsom iav (Ntau dua lossis sib npaug ntawm 10x);​
Dimensional Testing: Siv lub tshuab ntsuas kev sib koom tes (CMM) txhawm rau txheeb xyuas qhov loj me (npo txoj kab uas hla, flange thickness, tiv thaiv- zawv zawg qhov tob) tawm tsam EN 124 tus qauv;
Mechanical Testing: Sampling test-Tensile test (tensile strength, elongation), impact test (-20℃impact zog Ntau tshaj los yog sib npaug rau 20J);​​
Load Testing: Rau F900 npog, thov 900kN ntsug siab (1.2x rated load) rau 1 teev, tsis muaj deformation mus tas li los yog tawg;
Coating Testing: kuaj txheej zoo li (tsis muaj khiav, npuas, thiab lwm yam), thickness (DFT Ntau tshaj los yog sib npaug zos rau 80μm), adhesion (qib Tsawg dua los yog sib npaug rau 1), corrosion kuj (tsis muaj xeb liab nyob rau hauv 500- teev ntsev tsuag) thiab ziab kev ua tau zoo (tack-dawb lub sij hawm tsawg dua los yog sib npaug rau nws cov corrosion kuj. 2 teev)
