Cov qauv thiab kev sib txuas ntawm Dredging HDPE Pipes
1. Enlarged kawg, lossis flare kawg qee tus neeg hu, Tsis xav tau vuam.
2. Nodular cam khwb cia hlau ntxig rau thaum kawg los tiv thaiv nws ntawm deformation, tawg thiab to
3. Loose flang rings (carbon steel, galvanized) ntawm ob qhov kawg
4. Roj hmab gasket nyob nruab nrab ntawm thaum ob lub kav dej txuas nrog bolts thiab ceev.
Qhov zoo ntawm Dub Dredging Flanged HDPE Yeeb Nkab
1. Lub teeb yuag thiab hloov tau yooj yim: Dredging flanged HDPE kav tsuas hnyav ib feem yim ntawm cov kav hlau steel, ua rau lawv yooj yim rau nruab, disassemble, thiab thauj, txo cov sij hawm tsim kho, thiab txhim kho kev ua haujlwm.
2. Muaj zog corrosion kuj: Flanged HDPE kav dej muaj kev tiv thaiv corrosion zoo heev thiab tuaj yeem tiv taus kev yaig ntawm ntau yam tshuaj, nrog rau cov kua qaub thiab alkaline daws thiab cov dej ntsev, ua rau lawv haum rau ntau qhov chaw ib puag ncig.
3. Lub zog siab: Flanged HDPE kav dej muaj lub zog siab thiab siab ua haujlwm, tuaj yeem tiv taus cov dej loj thiab cov av siab, thiab tswj cov kav dej ruaj khov.
4. Smooth sab hauv thiab sab nrauv phab ntsa: Sab hauv phab ntsa ntawm lub raj xa dej yog du, nrog kev sib txhuam tsis zoo, uas tuaj yeem txhim kho kev thauj mus los ntawm cov dej, txo kev siv hluav taws xob thiab cov nqi khiav lag luam.
5. Muaj zog UV tsis kam: HDPE kav dej muaj zog UV tiv taus thiab kev laus, thiab lawv lub neej kev pab cuam ntev dua li cov kav hlau, PVC kav, cov kav dej nylon thiab cov kav dej yas zoo tib yam.
6. Lub neej ua haujlwm ntev: Raws li qhov tsim nyog, cov kav dej HDPE muaj lub neej ua haujlwm ntev heev thiab tuaj yeem hloov mus rau ntau qhov chaw hnyav, txo qhov zaus ntawm kev hloov thiab kev saib xyuas.
7. Kev siv dav dav rau kev siv: HDPE kav dej muaj qhov kub thiab txias ntawm -40 degree txog 60 degree thiab tuaj yeem hloov kho rau ntau yam huab cua. Txawm hais tias siv hauv dej lossis hauv av rau lub sijhawm ntev, lawv tuaj yeem ua haujlwm tau zoo
