Galvanized steel yeeb nkabyog cov yeeb nkab steel ua los ntawm txheej txheej ntawm zinc rau ntawm qhov chaw ntawm cov yeeb nkab steel zoo tib yam (carbon steel yeeb nkab). Zinc muaj cov khoom siv tshuaj lom neeg thiab tuaj yeem tsim cov yeeb yaj kiab oxide tuab, yog li cais cov pa oxygen thiab noo noo thiab tiv thaiv cov yeeb nkab steel los ntawm xeb.GI steel yeeb nkabyog cov yeeb nkab hlau nrog zinc txheej rau saum npoo ntawm cov yeeb nkab zoo tib yam los tiv thaiv corrosion. Nws muab faib ua kub-dip galvanizing thiab electro-galvanizing. Kub-dipgalvanized steel kavyog immersed nyob rau hauv molten zinc kua (kwv yees li 450 ° C) los tsim ib tug thicker zinc txheej (50-150μm), uas muaj zog corrosion kuj thiab yog haum rau sab nraum zoov los yog ib puag ncig ntub; electro-galvanized steel yeeb nkab txais cov txheej txheem electrolysis, zinc txheej yog nyias (5-30μm), tus nqi qis dua, thiab nws feem ntau yog siv hauv tsev.

Phab ntsa Thickness Thiab Kev Ntsuas Siab

1.Ordinary phab ntsa thickness (SCH40): tsim nyog rau kev thauj mus los ntawm cov dej tsis tshua muaj siab (xws li cov kav dej, cov kav dej).

2.Thickened phab ntsa thickness (SCH80): siab zog kuj, siv rau cov qauv kev txhawb nqa los yog high-pressure scenarios.

3.National standard phab ntsa thickness: Raws li tau teev tseg nyob rau hauv GB / T 3091, phab ntsa thickness DN20 galvanized steel yeeb nkab yog 2.8 hli (zoo li qib).

Ntev

1.Standard ntev: feem ntau 6 meters / thooj, 3m, 9m lossis 12m kuj tuaj yeem kho.

2.Fixed ntev: txiav raws li qhov yuav tsum tau ua, ± 10mm yuam kev raug tso cai.

Cov ntaub ntawv thiab cov qauv

1.Base yeeb nkab khoom:Q235 carbon hlau, Q345 low alloy steel, thiab lwm yam.

2. Galvanized txheej thickness:

(1) Kub-dip galvanizing: ≥65μm (GB / T 3091).

(2).Electrogalvanizing: 5 ~ 30μm (tsis muaj zog xeb).

3. Cov qauv kev coj ua:

(1) Suav teb: GB / T 3091 (welded galvanized yeeb nkab), GB / T 13793 (seamless galvanized yeeb nkab).

Galvanized Steel Yeeb Nkab Vuam Txheej Txheem

Loj Thiab Diameter

Vuam txoj kev: Feem ntau siv welding txoj kev muaj xws li phau ntawv arc vuam, roj shielded vuam, CO2 roj shielded vuam, thiab lwm yam.

Vuam npaj: Ua ntej welding, cov khoom paug xws li xim, xeb thiab av hauv qhov vuam yuav tsum tau muab tshem tawm kom ntseeg tau qhov zoo ntawm cov vuam.

Vuam txheej txheem: Thaum lub sij hawm vuam, tam sim no, voltage thiab vuam ceev yuav tsum tau tswj kom tsis txhob muaj teeb meem xws li undercut thiab tsis tiav kev nkag. Tom qab vuam, txias thiab trimming yuav tsum tau nqa tawm kom tsis txhob deformation thiab tawg.

Kev Tswjhwm Zoo: Thaum vuam, yuav tsum tau them nyiaj rau qhov flatness thiab smoothness ntawm vuam kom tsis txhob muaj qhov tsis xws luag xws li pores thiab slag inclusions. Yog tias pom muaj teeb meem vuam zoo, lawv yuav tsum tau kho thiab kho kom raws sijhawm.

Daim ntawv thov ntawm Galvanized Steel Yeeb Nkab
