Helical Welded Yeeb Nkab Rau Underground Dej Kab
Xav paub ntau ntxiv txog spiral welded kav:
Kauv welded yeeb nkabyog ib qho kev daws teeb meem tshiab rau cov kav dej hauv av.Nws yog tsim los ntawm welding steel strips los yog daim hlau / coil rau hauv ib ncig ntawm lub hauv paus mandrel.Cov txheej txheem no ua kom welded yeeb nkab nrog lub zog siab tshaj plaws, yooj thiab corrosion kuj.Cov yeeb nkab uas tshwm sim muaj ntau qhov zoo uas ua rau nws zoo tagnrho rau kev teeb tsa hauv av.

1. Lub zog thiab kav ntev:
Cov txheej txheem spiral welding ua rau lub zog tag nrho thiab kev ncaj ncees ntawm cov yeeb nkab.Nruam spiral welds faib kev ntxhov siab sib npaug ntawm qhov ntev, txo qhov kev pheej hmoo ntawm cov yeeb nkab tsis ua haujlwm.Txawm hais tias ntsib nrog av txav los yog sab nraud siab, kauv welded yeeb nkab tuaj yeem tiv taus cov teeb meem cuam tshuam nrog kev teeb tsa hauv av hauv lub sijhawm ntev.
2. Corrosion kuj:
Cov kab dej hauv av yog qhov ua rau corrosion vim dej noo, av acidity, thiab lwm yam ib puag ncig.Txawm li cas los xij, cov kav dej welded feem ntau yog coated nrog ntau cov txheej txheem tiv thaiv, xws li polyethylene lossis epoxy, ua raws li kev tiv thaiv corrosion.Cov txheej no pab txuas lub neej ntawm cov kav dej thiab txo cov nqi kho.
3. Yooj yim thiab yooj yim installation:
Vim nws cov qauv muab kauv, kauv welded yeeb nkab qhia tau zoo heev yooj, ua rau nws yooj yim dua thaum lub installation.Kev hloov pauv ntawm cov kav dej no tso cai rau kev ua kom zoo dua thiab muaj txiaj ntsig zoo txawm tias nyob rau hauv cov av nyuaj lossis thaum taug kev nyob ib puag ncig cov txheej txheem uas twb muaj lawm.Qhov kev hloov pauv no pab ua kom nrawm tsim kho thiab txo qis kev cuam tshuam rau zej zog thaum lub sijhawm teeb tsa.
4. Kev thauj mus los zoo:
Lub puab nto ntawm cov kauv welded yeeb nkab yog du, uas tuaj yeem txo kev sib txhuam thiab kev poob siab thaum dej ntws los ntawm cov yeeb nkab.Kev ua tau zoo ntawm kev khiav dej num ua kom muaj dej ntau ntxiv rau kev thauj mus los ntau dua, txhim kho kev faib dej thoob plaws lub network.
Hauv kev xaus:
Kauv welded yeeb nkab plays lub luag haujlwm tseem ceeb hauv kev tsim kho cov kav dej hauv av tau zoo, ua haujlwm tau zoo.Lawv lub zog, durability, corrosion kuj thiab yooj yim ntawm installation ua rau lawv thawj qhov kev xaiv rau engineers thiab project managers nrhiav kom ntev-ntev, txhim khu kev qha kev daws teeb meem.Los ntawm leveraging cov txiaj ntsig ntawm kauv welded yeeb nkab, cov zej zog tuaj yeem ua kom muaj kev thauj mus los hauv dej kom ruaj khov uas ua tau raws li kev xav tau ntawm cov neeg coob coob thaum txhawb kev txhim kho kev lag luam thiab kev saib xyuas ib puag ncig.
