Yuav Ua Li Cas Xaiv Galvanized Steel Yeeb Nkab: Ua tiav Cov Neeg Yuav Khoom Qhia
Galvanized steel yeeb nkab yog ib qho ntawm cov khoom siv dav tshaj plaws hauv kev tsim kho, kev tsim kho vaj tse, kav dej, thiab kev lag luam thoob ntiaj teb. Nws cov zinc txheej muab superior corrosion kuj piv rau cov yeeb nkab dub, ua rau nws zoo tagnrho rau siv sab hauv thiab sab nraum zoov. Txawm li cas los xij, nrog ntau qib, txheej hom, qhov ntau thiab tsawg, thiab cov qauv muaj, xaiv txoj cai galvanized steel yeeb nkab rau koj qhov project tshwj xeeb tuaj yeem nyuaj.
Cov lus qhia dav dav no qhia koj txog txhua yam koj xav paub - los ntawm kev nkag siab txog cov txheej txheem galvanizing los xaiv cov qib steel, zinc txheej thickness, yeeb nkab qhov ntev, thiab cov qauv thoob ntiaj teb. Txawm hais tias koj yog tus thawj saib xyuas kev muag khoom nrhiav cov khoom siv rau kev tsim kho loj lossis thawj zaug - lub sijhawm xa khoom, phau ntawv qhia no yuav pab koj txiav txim siab.
Galvanized steel yeeb nkab yog dab tsi?
Galvanized steel yeeb nkab yog carbon steel yeeb nkab uas tau coated nrog ib txheej ntawm zinc los tiv thaiv lub hauv paus hlau los ntawm corrosion. Cov txheej zinc ua raws li kev fij tseg - txawm tias qhov chaw raug khawb, zinc yuav corrode ua ntej, tiv thaiv cov hlau hauv qab. Cov txheej txheem no txuas ntxiv lub neej kev pabcuam ntawm cov yeeb nkab, feem ntau ntawm 15-20 xyoo (rau cov hlau tsis muaj xim dub) mus rau 50+ xyoo nyob rau hauv ib puag ncig ib puag ncig.
Hom txheej txheem Galvanizing
Kev nkag siab txog txoj kev galvanizing yog qhov tseem ceeb vim tias nws cuam tshuam ncaj qha rau txheej txheej thickness, durability, thiab nqi. Muaj ob txoj hauv kev siv hauv kev lag luam:
Kub-Dip Galvanizing
Kub-dip galvanizing yog txoj kev siv tau zoo tshaj plaws. Cov yeeb nkab steel yog tag nrho submerged hauv da dej ntawm molten zinc ntawm kwv yees li 450℃(842℃F). Cov txheej txheem no tsim cov hlau sib txuas ntawm cov zinc thiab hlau, ua rau cov txheej tuab tuab, feem ntau yog li ntawm 60 txog 275 g / m² (20-30μm). Cov kav dej kub-dip galvanized muaj kev tiv thaiv corrosion zoo dua thiab tsim nyog rau qhov hnyav sab nraum zoov, kev siv dej hiav txwv, thiab kev teeb tsa hauv av.
Qhov zoo ntawm kub-dip galvanizing:
Thicker, ntau ruaj zinc txheej
Ua kom tiav cov kev pab cuam nrog rau sab hauv
Metallurgical bond tiv thaiv txheej los ntawm tev
50+ xyoo kev pab cuam lub neej nyob rau hauv feem ntau ib puag ncig
Tus kheej- kho cov khoom ntawm cov npoo txiav
Ua ntej- Galvanizing (Electro-Galvanizing)
Ua ntej-galvanizing siv cov zinc txheej nyias los ntawm cov txheej txheem electrolytic los yog hla cov hlau los ntawm cov zinc molten da dej ua ntej tsim cov yeeb nkab. Cov txheej txheej feem ntau yog 10-15μm tuab - thinner dua kub-dip galvanizing. Ua ntej- cov kav dej galvanized yog tus nqi ntau dua thiab tsim nyog rau kev siv sab hauv tsev lossis ib puag ncig uas muaj kev pheej hmoo corrosion tsawg.
Thaum twg los xaiv ua ntej -galvanized yeeb nkab:
Kev siv sab hauv tsev nrog kev tswj hwm ib puag ncig
Cov phiaj xwm nrog kev txwv nyiaj txiag
Daim ntawv thov qhov zoo nkauj tseem ceeb tshaj qhov ua tau zoo heev
Lub teeb -cov haujlwm ua haujlwm ntawm cov qauv siv
Cov ntsiab lus tseem ceeb los xav txog thaum xaiv Galvanized Steel Yeeb Nkab
1. Qib steel
Cov qib steel txiav txim siab cov yeeb nkab cov khoom siv kho tshuab - tensile zog, yield zog, thiab elongation. Cov qib zoo rau galvanized steel yeeb nkab muaj xws li:
| Qib Steel | Yield zog (MPa) | Tensile zog (MPa) | Elongation (%) | Common Standard |
|---|---|---|---|---|
| Q195 | Ntau dua lossis sib npaug rau 195 | 315-430 | Ntau dua lossis sib npaug 22 | GB/T 700 |
| Q235 | Ntau dua lossis sib npaug li 235 | 375-500 | Ntau dua lossis sib npaug li 26 | GB/T 700 |
| Q345 | Ntau dua lossis sib npaug rau 345 | 470-630 | Ntau dua lossis sib npaug 22 | GB/T 1591 |
| ASTM A53 | Ntau dua lossis sib npaug li 240 | Ntau dua lossis sib npaug rau 330 | - | ASTM A53 |
| St37 | Ntau dua lossis sib npaug li 235 | 360-510 | Ntau dua lossis sib npaug li 24 | TIAB SA 1626 |
Rau feem ntau siv kev tsim kho,Q235yog qib feem ntau siv vim nws qhov sib npaug zoo ntawm lub zog, weldability, thiab tus nqi. Rau siab dua - lub zog yuav tsum muaj xws li thauj khoom - cov qauv kabmob,Q345pom zoo. Rau export rau North America,ASTM A53feem ntau tau teev tseg kom tau raws li cov cai hauv zos.
2. Zinc Txheej Thickness
Zinc txheej thickness yog ib qho tseem ceeb tshaj plaws hauv kev txiav txim siab corrosion thiab kev pab cuam lub neej ntawm galvanized steel yeeb nkab. Txheej thickness feem ntau ntsuas hauv grams ib square meter (g / m²) lossis micrometers (μm):
| Txheej hnyav | Thickness (hli) | Corrosion Resistance | Pom zoo siv |
|---|---|---|---|
| 60-120 g/m² | 8-17 | Teeb | Nyob sab hauv tsev, ib puag ncig qhuav |
| 120-200 g/m² | 17-28 | Nruab nrab | Sab nraum zoov, dav dav atmospheric |
| 200-275 g/m² | 28-39 | Hnyav | Marine, industrial, underground |
| 275+ g/m² | 39+ | Mob hnyav | Ib puag ncig corrosion heev |
Pro tswv yim:Rau tej yaam num nyob rau hauv lub ntug dej hiav txwv cheeb tsam los yog cheeb tsam uas muaj high humidity thiab ntsev raug, nco ntsoov qhia ib tug tsawg kawg nkaus txheej ntawm 200 g / m². Rau kev teeb tsa hauv av, 275 g / m² lossis thicker yog pom zoo.
3. Pipe Dimensions: Outer Diameter, Phab Ntsa Thickness, thiab Ntev

Cov lus nug nquag
Q: Ntev npaum li cas galvanized steel yeeb nkab nyob sab nraum zoov?
A: Nyob rau hauv cov xwm txheej huab cua, galvanized steel yeeb nkab tuaj yeem nyob ntev 50+ xyoo. Nyob rau hauv ntug dej hiav txwv los yog ib puag ncig muaj kev lag luam, lub neej kev pab cuam yuav raug txo mus rau 30-40 xyoo nyob ntawm zinc txheej thickness. Kev teeb tsa hauv av hauv av nrog pH nruab nrab tuaj yeem nyob tau 75+ xyoo.
Q: galvanized steel yeeb nkab puas siv tau rau cov dej haus?
A: Txawm hais tias galvanized steel yeeb nkab yog keeb kwm siv rau kev siv dej, ntau lub teb chaws tam sim no txwv tsis pub siv cov dej haus vim muaj peev xwm zinc leaching thiab cov kab mob txhuas los ntawm cov kav dej qub. Rau kev siv dej haus, xyuas cov kev cai hauv zos - tooj liab, PEX, lossis stainless hlau kav feem ntau nyiam rau kev teeb tsa tshiab.
Q: Can galvanized steel yeeb nkab yuav welded?
A: Yog, tab sis cov zinc txheej yuav tsum tau muab tshem tawm ntawm qhov chaw weld ua ntej. Vuam galvanized steel tsim cov zinc oxide fumes uas muaj kev phom sij rau kev noj qab haus huv. Kev ua pa kom raug thiab kev tiv thaiv ua pa yog qhov tseem ceeb. Tom qab vuam, qhov chaw vuam yuav tsum tau rov ua dua -coated nrog zinc- cov xim nplua nuj lossis txias galvanizing compound kom rov qab tiv thaiv corrosion.
Q: Qhov txawv ntawm galvanized thiab galvannealed steel yog dab tsi?
A: Galvannealed steel tau txais kev kho cua sov ntxiv tom qab galvanizing, uas alloys zinc nrog cov hlau nto los ua ib qho nyuaj, ntau xim -adherent txheej. Galvannealed steel yog qhov zoo tagnrho rau cov ntawv thov uas yuav tsum tau pleev xim, thaum tus qauv galvanized steel yog qhov zoo dua rau cov khoom nyoos.
