QT500-7 ductile hlau D400 hnyav- lub luag haujlwm manhole npog yog lub hauv paus thiab kev lag luam manhole npog tshwj xeeb tsim los rau hnyav- daim ntawv thov. Nws qhov zoo yog nyob rau hauv nws cov khoom tawv, muaj zog load- bearing muaj peev xwm, thiab haum rau ntau yam high-load puag ncig, ntsuas practicality thiab durability.
Khoom zoo:Ua los ntawm QT500-7 qib ductile hlau, tab tom ua kom yaj thiab spheroidizing kev kho mob, nws khav theeb lub zog tensile tshaj 500MPa thiab elongation ntawm tsis pub tsawg tshaj 7%. Piv nrog rau cov grey cam khwb cia hlau zoo tib yam, nws cov toughness yog ho txhim kho, ua rau nws tsis tshua muaj kev tawg thiab cuam tshuam-resistant. Nws tiv taus qhov hnyav hnyav ntawm lub tsheb hnyav thiab kev cuam tshuam sab nraud, tiv thaiv kev nyab xeeb xws li manhole npog kev puas tsuaj thiab tawg.
Load-cov kabmob txheem:Ua raws li cov qauv EN124 D400 nruj me ntsis, nrog rau lub nra hnyav txog li 40 tons, nws tuaj yeem yooj yim tuaj yeem rov ua dua los ntawm cov tsheb hnyav xws li tsheb loj thiab tsheb tsim kho. Nws yog dav siv tau rau hnyav- cov xwm txheej xws li hauv nroog txoj kev loj, txoj kev loj, chaw nres tsheb thauj khoom, tshav dav hlau thauj khoom, thiab chaw ua lag luam. Nws kuj tseem tuaj yeem siv rau kev sib khi thiab tiv thaiv ntau yam kev soj ntsuam qhov dej hauv nroog, roj, hluav taws xob, thiab kev sib txuas lus.
Tus Qauv Tsim:
Sib npaug practicality thiab kev nyab xeeb, lub manhole npog lub cev nta ib tug thickened tsim nrog chamfered npoo los tiv thaiv khawb los ntawm ntse ces kaum. Ntau qhov kev txhawb nqa cov tav tau ntxiv rau hauv qab txhawm rau txhim kho tag nrho cov load-cov kabmob muaj peev xwm thiab cov qauv kev ruaj ntseg, tiv thaiv kev deformation ntev - siv sijhawm ntev. Nws tseem tau nruab nrog kev poob siab- nqus cov nplhaib roj hmab kom zoo txo cov suab nrov ntawm kev sib tsoo ntawm lub hau npog thiab lub hauv paus, tiv thaiv lub hau kom tsis txhob dhia tawm thaum lub tsheb tsav tsheb hla nws, txhim kho kev nyab xeeb thiab kev nyab xeeb, thiab tseem muab qee qhov kev tiv thaiv dej thiab plua plav los tiv thaiv cov chaw hauv av.
Anti- txheej txheem corrosion:
Utilizing a hot-dip galvanizing + asphalt double-layer coating process, the uniform and dense galvanized layer effectively isolates air and moisture, preventing rust and corrosion of the cast iron material. Sab nrauv asphalt txheej ntxiv txhim khu kev hnav thiab kev tiv thaiv corrosion, ua rau nws tsim nyog rau qhov chaw sab nraum zoov hnyav, ua kom cov khoom lag luam txuas ntxiv thiab txo cov nqi kho tom ntej.
Nto thiab Installation:
Featuring anti-slip textured design, nws ua rau muaj kev sib txhuam, tiv thaiv cov neeg taug kev thiab tsheb kom tsis txhob ntog txawm nyob rau hauv qhov chaw ntub dej xws li los nag lossis daus, ua kom muaj kev nyab xeeb ntawm kev tsheb. Cov khoom feem ntau yog puag ncig lossis square, tab sis qhov ntev tuaj yeem kho raws li qhov tseeb manhole specifications. Nws yog ib qho yooj yim rau nruab, muaj kev sib khi zoo heev, thiab tiv thaiv cov khib nyiab thiab dej nag los ntawm kev nkag mus rau hauv lub qhov dej, tiv thaiv cov kav dej rau kev ua haujlwm ib txwm muaj.
