Ntawm ib sab
| Spec | Ntau yam |
|---|---|
| Sab nraud txoj kab uas hla | 15mm-219mm (1/2 "- 8") |
| Phab ntsa Thickness | 1.2mm-8.0 hli |
| Weld txheej txheem | ERW (hluav taws xob kuj welded) |
| Txheej txheej txheej | Ncej -galvanized (welded liab qab, ces kub-dip) |
| Zinc Txheej Nyhav | 40–90 g/m² (pre-galv, typical) lossis 275–600 g/m² (post-galv, ASTM A123-chav)) |

Cov txheej txheej hnyav saum toj no tsis yog qhov sib txawv ntawm - ua ntej-galvanized thiab post-galvanized yeeb nkab tiag tiag nqa cov zinc sib txawv, thiab qhov sib txawv yog thawj qhov kev daws teeb meem ua ntej muab cov khoom sib piv ntawm tus nqi.
Lub diav rawg Qhov Tseem Ceeb Tseem Ceeb: Thaum Twg Qhov Vuam Zoo Li Cas?
Ob qhov sib txawv ntau lawm ua ntu zus ob qho tag nrho sau npe "galvanized welded yeeb nkab":
| Ua ntej-Galvanized (weld-los ntawm-coated- sawb) | Ncej -Galvanized (weld-ces-dip) | |
|---|---|---|
| Ib ntus | Steel strip yog galvanized ua ntej, ces yob - tsim thiab welded | Bare steel strip yog welded rau hauv cov yeeb nkab ua ntej, ces tag nrho cov yeeb nkab yog kub -dip galvanized |
| Weld seam txheej | Nyias los yog liab qab ntawm seam - welding burns tawm zinc hauv zos | Tag nrho, niaj hnub txheej txhua qhov chaw, nrog rau cov seam |
| Qhov hnyav zinc hnyav | 40–90 g/m² | 275–600 g/m² |
| Corrosion lub neej (seam) | Tsis muaj zog taw tes - seam corrodes ua ntej yam tsis tau kov-nce | Tsis muaj zog taw tes - seam yog dipped nrog rau tus so |
| Nqi | qis | 20–40% siab dua |
| Zoo tshaj plaws | Qhuav kev pabcuam sab hauv tsev, luv- siv sab nraum zoov, qis- ib puag ncig corrosion | Sab nraum zoov, ntub dej, faus, lossis kev pabcuam ntug hiav txwv; nyob qhov twg seam tsis ua hauj lwm yog tsim nyog |
Qhov no yog ib qho kev nkag siab tsis zoo nyob rau hauv "galvanized yeeb nkab" qhov chaw. Tus neeg yuav khoom sib piv ob nqe lus uas tsis tau nug seb qhov twg tau siv yog muab piv rau ob yam khoom sib txawv ntawm ob lub ntsiab lus sib txawv, tsis yog ob tus neeg muag khoom ntawm tib yam khoom.
Tus Nqi Tag Nrho Cov Tswv Cuab: Ua ntej- vs Post- Galvanized
Tus nqi pem hauv ntej qhia tsuas yog ib feem ntawm zaj dab neeg. Nyob rau lub neej kev pabcuam tiag tiag, ob txoj kev txheej txheej sib txawv ntawm qhov sib txawv thaum muaj kev cuam tshuam corrosive nyob rau hauv daim duab:
| Ua ntej- Galvanized | Ncej -Galvanized | |
|---|---|---|
| Tus nqi khoom siv ua ntej | Lub hauv paus | +20–40% |
| Seam kov- xav tau (siv sab nraum zoov) | Feem ntau hauv 2-5 xyoos | Tsis tshua muaj, yog tias puas tau |
| Lub neej kev pab xav tau (qhuav / sab hauv) | 15–{1}} xyoo | 20–{1}} xyoo |
| Lub neej kev pab xav tau (sab nraum zoov / ntub dej) | 3-8 xyoo ua ntej seam tsis ua hauj lwm | 15-25 xyoo |
| Maintenance Labor (sab nraum) | Rov ua dua - tshuaj tsuag/paint reapplication ntawm seam | Tsawg kawg |
| Ua tsis tiav hom | Localized seam xeb, feem ntau unnoticed kom txog thaum to | Uniform txheej degradation, xav tau ntau dua |
Crossover point yog raug, tsis yog nqi. Hauv tsev, qhov pheej yig dua ua ntej-galvanized xaiv feem ntau yeej ntawm tus nqi tag nrho vim tsis muaj dab tsi thawb seam corrosion. Sab nraum zoov, tus lej hloov pauv sai sai - ib puag ncig ntawm seam kov- nce kev ua haujlwm, lossis ib qho kev hloov yeeb nkab thaum ntxov, feem ntau tshem tawm tag nrho cov nyiaj khaws cia los ntawm kev xaiv ua ntej -galvanized hauv thawj qhov chaw. Cov neeg yuav khoom optimizing purely rau chav tsev nqi ntawm ib txoj hauj lwm sab nraum zoov yog feem ntau optimizing rau tus lej tsis raug.
Weld Seam Inspection - Yuav Ua Li Cas Xyuas Ntawm Daim Ntawv Txais
- Visual seam continuity: tsis muaj cov kab liab liab liab khiav qhov ntev ntawm cov yeeb nkab
- Txheej hnyav pov thawj: sib nqus thickness ntsuas kev nyeem ntawv ntawm seam vs. lub cev - qhov sib txawv loj qhia ua ntej-galv cov khoom xa tuaj raws li ncej-galv
- Spangle/finish check: ncej-galv yeeb nkab qhia pom pom crystalline zinc spangle thoob plaws tag nrho saum npoo nrog rau cov seam; ua ntej-galv seams feem ntau zoo li duller lossis matte los ntawm kev sib piv
- Mill daim ntawv pov thawj: yuav tsum txheej txheej txheej txheej hauv xeev (ua ntej- lossis tshaj tawm-) qhia meej, tsis yog "galvanized" xwb
Cov lus nug nquag nug (FAQ)
Q: Puas yog vuam puas ua rau cov galvanized txheej ntawm ncej-galvanized yeeb nkab?
A: Lub zeb weld tshwm sim ua ntej galvanizing, yog li lub Hoobkas seam yog coated tag nrho. Field welding lossis txiav ncej-galv yeeb nkab tom qab kev teeb tsa tau hlawv cov zinc hauv zos ntawm qhov txiav / vuam thiab yuav tsum tau kov- txheej txheej.
Q: Dab tsi txheej hnyav kuv yuav tsum nug rau ntawm ncej-galvanized yeeb nkab?
A: ASTM A123 teeb tsa qhov tsawg kawg nkaus los ntawm phab ntsa tuab, feem ntau nyob rau hauv 350-600 g / m² ntau rau cov yeeb nkab phab ntsa tuab - nug koj tus neeg muag khoom kom paub meej cov chav kawm siv rau koj qhov tshwj xeeb OD / WT es tsis lees txais ib daim pam tus lej.
Q: Kuv tuaj yeem qhia hom twg kuv raug hais yam tsis muaj kev kuaj sim?
A: Nug tus neeg muag khoom ncaj qha thiab tau sau rau hauv daim ntawv pov thawj PO thiab zeb daim ntawv pov thawj - pom, ib qho kev tshaj tawm tiag tiag -galv yeeb nkab qhia cov zinc txuas txuas ntxiv hla lub seam, thaum ua ntej -galv feem ntau qhia pom cov kab seam txawv ntawm lub cev tiav.
Q: Puas yog ua ntej-galvanized lossis post-galvanized yeeb nkab zoo dua rau cov xov?
A: Tsis yog txheej txheej muaj sia nyob threading zoo li qub - txiav threads nthuav tawm liab qab hlau ntawm qhov sib koom ua ke ntawm ob hom, yog li kev sib txuas threaded feem ntau xav tau cov yeeb nkab dope lossis sealant txawm tias siv txoj kev galvanizing.
