Galvanized steel kav

Galvanized steel kav yog welded steel kav ua los ntawm kub-dip galvanizing carbon steel los tsim ib txheej zinc tiv thaiv, txhim kho cov yeeb nkab corrosion kuj thiab txuas nws lub neej kev pab cuam. Raws li cov khoom siv tseem ceeb hauv kev tsim kho, kev tsim vaj tsev hauv nroog, thiab kev lag luam, cov kav hlau galvanized tau dhau los ua cov khoom siv tsis tseem ceeb hauv kev tsim vaj tsev niaj hnub vim lawv cov nqi siab -kev ua tau zoo thiab kev tiv thaiv kev ua tau zoo.

 Peb lub tuam txhab muaj ntau yam ntawm galvanized raj yeeb nkab specifications, npog ntau yam kev xav tau los ntawm micro mus rau ntxiv - loj diameters.

Raws li lub teb chaws tus qauv GB / T 3091-2015, ntau specifications muaj xws li ntawm DN15 mus rau DN200, sib xws rau sab diameters ntawm 21.3mm mus rau 219.1mm. Phab ntsa thickness sib txawv nyob ntawm qhov ntsuas siab, feem ntau yog los ntawm 1.5mm txog 6.0mm, nrog SCH40 thiab SCH80 feem ntau siv cov kev lag luam tshwj xeeb.

 Galvanized tubing yog muaj nyob rau hauv tus qauv ntev ntawm 6 meters, 9 meters, los yog 12 meters, nrog rau 6 meters yog lub feem ntau kev lag luam specification. Kev cai ntev txog li 18 meters kuj tuaj yeem ua raws li kev thov.

 Zinc txheej thickness yog ib qho tseem ceeb zoo qhia.

Raws li GB / T 13912-2002, thaum lub workpiece thickness ntau dua los yog sib npaug rau 6 hli, qhov nruab nrab zinc txheej thickness tshaj 85 micrometers, nrog ib lub zos thickness tsis tsawg tshaj li 70 micrometers; Thaum lub workpiece thickness yog nyob nruab nrab ntawm 3-6 hli, qhov nruab nrab thickness yuav tsum tshaj 70 micrometers, nrog ib lub zos thickness ntawm tsis tsawg tshaj li 55 micrometers.

Rau galvanized steel pipework siv nyob rau hauv cov huab cua puag ncig, qhov nruab nrab thickness ntawm zinc txheej yuav tsum tsis muaj tsawg tshaj li 50-70 micrometers, thiab lub zos thickness yuav tsum tsis pub tsawg tshaj li 40-56 micrometers.

 Superior Rust thiab Corrosion Resistance

The zinc coating on galvanized pipes naturally forms a dense protective zinc oxide film, effectively isolating it from air, moisture, and acid/alkali corrosion. Nyob rau hauv cov huab cua ib puag ncig, nws lub neej kev pabcuam tuaj yeem ncav cuag 15-20 xyoo; nyob rau hauv qhuav sab hauv ib puag ncig, nws lifespan yog txawm ntev dua. Txawm tias muaj kev khawb hauv zos, cov zinc txheej tuaj yeem tiv thaiv cov hlau raug xeb los ntawm xeb rau 5-8 xyoo los ntawm cov tshuaj tiv thaiv electrochemical.

 Lub teeb thiab siab -Lub zog

Thaum tuav lub zog qub ntawm cov yeeb nkab steel, zinc txheej txhim kho qhov hnav tsis kam, ua rau cov nqi tu qis.

 Kev ua haujlwm yooj yim

Galvanized kav dej muaj ib tug du nto, tsis muaj qhov tsis xws luag xws li zinc nodules thiab tsis tiav galvanizing, pab txhawb kev ua haujlwm theem nrab xws li txiav, threading, dabtsi yog khoov, thiab stamping. Nws cov ductility zoo ua rau nws tsis tshua muaj kev tawg los yog tev tawm thaum txias khoov, flaring, thiab flattening.

 Hygienic thiab Environmentally Friendly

Kub-dip galvanized kav dej raws li cov qauv kev thauj mus los ntawm cov dej haus, tsis yog - tshuaj lom thiab ib puag ncig, thiab tuaj yeem siv rau hauv cov kav dej kav dej. Thaum electro- cov kav dej galvanized raug txwv tsis pub ua cov kav dej hauv cov tsev tsim kho tshiab, cov kav dej kub -dip galvanized tseem tuaj yeem siv nyab xeeb.

1. Txhais qhov kev siv ib puag ncig

Sab nraum zoov / Humid Ib puag ncig: Xaiv cov zinc txheej ntau dua lossis sib npaug ntawm 275g / m², phab ntsa thickness Ntau dua lossis sib npaug li 3.0mm

Ntug hiav txwv / Chemical Ib puag ncig: Pom zoo zinc txheej Ntau dua lossis sib npaug ntawm 500g / m² lossis siv 316L stainless hlau ua lwm txoj hauv kev

2. Tshawb xyuas Cov Qauv Ua Raws Cai

Xyuas kom cov khoom ua raws li cov qauv hauv tebchaws lossis thoob ntiaj teb. Cov khoom xa tawm yuav tsum ua kom tau raws li cov ntawv pov thawj uas yuav tsum tau ua ntawm lub hom phiaj kev lag luam. Tag nrho peb cov khoom ua tau raws li cov qauv thiab tuaj yeem muab daim ntawv pov thawj thiab thib peb -kev xeem.

Qhov chaw txiav yuav tsum tau kho los ntawm kev siv cov xim txias galvanizing lossis zinc -nplua nuj primer. Kev kho tib yam yuav tsum tau siv rau thaj tsam 100 hli ntawm ob sab ntawm cov vuam tom qab vuam. Tsis txhob sib cuag nrog cov kua qaub, alkalis, thiab ntsev thaum khaws cia; ua kom thaj chaw qhuav thiab zoo -ventilated.
