DN600 Hlau Manhole Npog

Lub spheroidalmanhole cover yog ib hom spheroidal graphite cam khwb cia hlau. Cov spheroidal graphite cam khwb cia spheroidal graphite yog spheroidized thiab inoculated kom zoo txhim kho cov khoom ntawm cov hlau cam khwb cia, tshwj xeeb tshaj yog cov yas thiab toughness, yog li tau txais lub zog siab dua cov pa roj carbon steel. Ductile hlau yog ib yam khoom uas muaj zog cam khwb cia hlau tsim nyob rau hauv 1950s. Nws txoj kev ua tau zoo yog ze rau ntawm cov hlau. Nws yog ua raws li nws cov kev ua tau zoo heev thiab tau ua tiav siv rau kev ua haujlwm ntawm qee qhov nyuaj, lub zog, toughness thiab hnav tsis kam. Cov khoom uas xav tau ntau dua. Ductile hlau tau tsim sai sai rau hauv cov khoom siv cam khwb cia hlau tom qab grey cam khwb cia hlau. Lub npe hu ua "hlau-raws li steel" feem ntau yog hais txog cov hlau ductile.

Daim ntawv thov
(1) Hluav taws xob cov kav dej zoo; Post, telecommunication, kev sib txuas lus pipeline zoo;
(2) Txoj kev teeb pom kev zoo, hluav taws kub tswj zoo, txhua yam valve zoo;
(3) Cov dej hauv nroog, cov kav dej ntws zoo; Thaum tshav kub kub, roj zoo;
(4) Anti-corrosion project, qhib kwj; Nws zoo li tuaj yeem ua raws li cov neeg siv khoom xav tau.

1. Tawm tsam tub sab nyiag - Composite Manhole Cover nrog shockproof roj hmab sealing yog non-metallic, non-conductive thiab non-sparking, tsis muaj nuj nqis ntawm recycling, tag nrho daws cov teeb meem tub sab.

2. Muaj peev xwm thauj khoom -Nws cov khoom tseem ceeb yog fiberglass thiab unsaturated resin. oad muaj peev xwm yog A15, B125, C250, D400, E600.

3. Kev tsim dawb-xws li Xim, Logo, Vaj Huam Sib Luag, Load thiab Dimension tuaj yeem tsim raws li cov neeg siv khoom xav tau.

4. Lub neej ntev - Qhov tsawg kawg nkaus lifespan yog 30 xyoo tsis muaj kev saib xyuas.

5. Zoo kaw -Nws tuaj yeem ntsia tau hermetically, thiab tiv thaiv kom tsis txhob muaj pa phem tawm ntawm cesspool. thiab tsis muaj suab nrov muaj kuab paug los yog rebound.

6. Zoo hnav thiab corrosion kuj -Nws yuav tsis xeb vim nws muaj zoo hnav thiab corrosion kuj.

7. Qhov kub thiab txias tsis kam - Cov rwb thaiv tsev zoo heev (ntawm-40 ° C ~ 200 ° C)

8. Qhov hnyav dua thiab tus nqi sib tw ntau dua - qhov hnyav ntawm qhov sib xyaw manhole npog tshwj xeeb tshaj yog SMC manhole npog yog sib dua. Composite manhole npog yog yooj yim dua rau kev thauj, nruab thiab kho.
