Hlau conduits yog cov kav hlau uas los ntawm cov xov hlau hluav taws xob thiab cables khiav

Hlau conduits yog cov kav hlau uas los ntawm cov xov hlau hluav taws xob thiab cables khiav.Nws muaj kev tiv thaiv tseem ceeb rau cov xov hlau thiab cables los ntawm kev puas tsuaj thiab kev cuam tshuam.
Henfen muaj cov kav dej zoo uas muaj cov zinc coated, kub dip galvanized ob sab hauv thiab sab nraud.Ua raws li BS 4568 EN-BS31-1940.
Tsis tas li, Henfen muaj ntau yam khoom siv hlau txuas.
Henfen muab ob hom kab hlau galvanized kav: British standard thiab American standard.Cov qauv tseem ceeb hauv tebchaws Askiv yog BS4568 thiab BS31-1940.Qhov loj yog tsuas yog 20mm, 25mm, 32mm.Cov kav hlau no tuaj yeem ua tau welded, tab sis yuav tsum tau ua tib zoo saib xyuas cov khoom siv tes ua haujlwm.Tom qab vuam, cov yeeb nkab galvanized yuav tsum tau polished, txwv tsis pub qhov zoo yuav raug cuam tshuam, thiab loj blistering los yog xeb yuav tshwm sim.Galvanized kav yog tsuas yog siv rau kev tiv thaiv ntawm cov xov hlau thiab cables.Feem ntau ntawm cov tsev qub siv cov kav dej galvanized.Tam sim no galvanized yeeb nkab kuj siv rau cov roj thiab cua sov.
Dab tsi yog cov yam ntxwv ntawm galvanized yeeb nkab?
1. Cov nqi ua haujlwm qis: Cov nqi tiv thaiv xeb ntawm kub-dip galvanizing yog qis dua lwm cov xim thiab cov txheej txheem, thiab tus nqi qis heev.
2. Durable: Qhov saum npoo ntawm cov yeeb nkab kub-dip galvanized steel yeeb nkab yog qhov tshwj xeeb tshaj yog ci, zinc txheej yog zoo ib yam, tsis muaj to, tsis muaj dej, muaj zog adhesion thiab muaj zog corrosion kuj.Lub cheeb tsam suburban tau nce siab, thiab tus qauv kub-dip galvanized anti-corrosion thickness feem ntau tuaj yeem khaws cia rau ntau tshaj 50 xyoo yam tsis muaj kev saib xyuas.Hauv cov nroog lossis sab ntug dej hiav txwv, cov txheej txheem kub-dip galvanized los tiv thaiv corrosion tuaj yeem khaws cia txog li 20 xyoo yam tsis tau kho.
3. Kev ntseeg tau zoo: Cov txheej txheej saum npoo ntawm cov yeeb nkab galvanized yog metallurgically ua ke nrog cov hlau, thiab cov yeeb nkab steel galvanized yog tsim rau saum npoo ntawm cov hlau, yog li cov kav ntev ntawm cov txheej txheem kuj tseem txhim khu kev qha.
4. Cov txheej txheej muaj zog toughness: cov zinc txheej ua ib qho tshwj xeeb metallographic qauv, uas feem ntau tuaj yeem tiv thaiv kev puas tsuaj thaum thauj thiab siv.
5. Kev tiv thaiv zoo: Txhua feem ntawm cov nyiaj seem tuaj yeem raug galvanized, txawm tias qhov chaw so, cov ces kaum ntse thiab qhov chaw nkaum tuaj yeem tiv thaiv tag nrho.
6. Txuag lub sijhawm thiab cov neeg ua haujlwm: Cov txheej txheem galvanizing sai dua li lwm txoj kev siv txheej txheej, uas tuaj yeem zam lub sijhawm yuav tsum tau pleev xim rau ntawm qhov chaw tsim kho tom qab kev teeb tsa.
