Yam khoom tseem ceeb

Hnyav-Lub luag haujlwm Load-Bearing Capacity

Ua raws li GB / T23858 thiab EN124 tus qauv, muaj qhov ntsuas D400 load (400 kN). Haum rau hnyav- txoj haujlwm hauv nroog, nws ua kom haum rau kev txuas ntxiv ntawm 40-tuj hnyav tsheb thauj khoom, tsheb thauj khoom, thiab tsheb npav.

Siab -Toughness Ductile Hlau Khoom

Tsim los ntawm QT500-7 ductile hlau nrog spheroidal graphite qauv. Nws muaj lub zog tensile siab, cuam tshuam tsis kam, thiab ua haujlwm ntev tiv thaiv kev rov ua haujlwm ntau dua; nws yog resistant rau fracturing los yog crumbling, muab ib tug muaj kev ruaj ntseg yam nyob deb tshaj ntawm tus qauv grey cam khwb cia hlau.

Superior Structural Load Distribution

Lub voj voog tsim tshem tawm cov ntsiab lus ntawm kev ntxhov siab, kom ntseeg tau tias cov khoom thauj tsis sib xws thaum tsheb hla dhau. Nws zam lub ces kaum tawg los yog ntug lifting teeb meem tshwm sim nrog cov square npog, uas ua rau ib tug ruaj khov qauv uas yog resistant mus rau kev puas tsuaj los yog misalignment.

Competitive Advantage

Piv rau grey cam khwb cia hlau manhole npog

Muab superior toughness, ua rau nws resistant rau fracturing nyob rau hauv hnyav loads; sib dua hauv qhov hnyav rau tib lub peev xwm thauj khoom; nta ib qho kev tsim kho kom zoo rau kev poob siab thiab txo suab nrov, thiab tsis tshua muaj tub sab nyiag; txo qis ntawm kev tawg thiab tawg, ua rau txo qis - cov nqi tu lub sijhawm.

product-374-265

Muab piv rau cov khoom sib xyaw ua ke manhole npog

Kev thauj khoom zoo tshaj plaws -cov kabmob muaj peev xwm- resin npog feem ntau tawm ntawm chav kawm C250 thiab tsis tuaj yeem tiv taus tsheb hnyav; muaj qhov zoo heev - kub thiab kev laus tiv thaiv, tswj nws cov duab nyob rau hauv lub caij nyoog tsheb hnyav; haum rau hnyav- daim ntawv thov lub luag haujlwm ntawm txoj kev loj thiab muaj ntau qhov kev siv dav.

Piv rau square hnyav -cov haujlwm manhole npog

Lub voj voog npog faib cov kev ntxhov siab sib npaug yam tsis muaj kev ntxhov siab ntawm cov ces kaum, ua rau lawv tsis tshua qaij lossis tawg nyob rau hauv ntev - tsheb khiav; tsim los siv cov txheej txheem tsim khoom lag luam nrog ntau yam kev qhia tshwj xeeb yooj yim muaj; yooj yim rau tig thiab ua kom zoo thaum lub sij hawm saib xyuas.

Kev Tiv Thaiv Kev Tiv Thaiv

Compact lub hauv paus thiab theem nrog pob zeb; dlhos ncej sab saum toj nrog txoj kev nto.
Nruab nrab ntawm lub thav duab, ncuav cov pob zeb hauv qab los tiv thaiv -kev daws teeb meem flange.
Txhim kho EPDM roj hmab gasket hauv qhov zawj yam tsis muaj kev cuam tshuam.
Kho lub pob khawm thiab ntsuas phoo kom ntseeg tau tias qhib qhib thiab tsis muaj kev co.
Tsis txhob dov lub hau nrog hnyav txoj kev roller; qhib kev khiav tsheb tom qab kho tag nrho.
Tsis txhob ntaus hnyav los yog nyem lub hau kom tsis txhob tawg.
