Dab tsi "Galvanized" txhais tau tias nyob rau hauv A53
A53 tsis yog tsuas yog hais tias "ntxiv zinc" - nws teev nws tus kheej qhov hnyav txheej txheej tsawg kawg nkaus, cais los ntawm ASTM A123 lub rooj feem ntau hais txog cov qauv hlau. Rau cov yeeb nkab, tus lej ua haujlwm cov neeg yuav khoom yuav tsum tau kuaj xyuas ntawm daim ntawv pov thawj zeb yog1.8 oz / ft² nruab nrab, 1.6 oz / ft² yam tsawg kawg nkaus ntawm ib qho chaw, txheeb xyuas los ntawm qhov hnyav- ntawm- txheej ntsuas lossis ntsuas qhov sib nqus tuab. Ib daim ntawv pov thawj uas tsuas yog hais tias "kub-dip galvanized ib A153" yam tsis muaj txheej txheej - hnyav daim duab tsis yog, los ntawm nws tus kheej, pov thawj ntawm A53 ua raws - A153 tswj hwm cov galvanizing ntawm fittings thiab kho vajtse, tsis yog yeeb nkab.
Galvanizing yog siv tom qab cov yeeb nkab tau tsim thiab kuaj rau qib, ntawm kwv yees li 450℃(840℃F). Qhov no yog qhov zoo hauv qab qhov kub thiab txias uas yuav hloov pauv lub hauv paus hlau cov khoom siv kho tshuab, yog li cov yeeb nkab A53 galvanized yog tib yam yield zog, tensile lub zog, thiab elongation yuav tsum tau raws li nws cov dub sib npaug hauv tib qib - txheej hloov cov cwj pwm corrosion, tsis ua haujlwm zoo.
Hom E, S, thiab F: Tsis yog txhua qhov sib npaug muaj Galvanized
Qhov no tseem ceeb tshaj rau cov khoom siv galvanized dua li cov yeeb nkab dub, vim tias cov qauv ntawm cov khoom sib txawv los ntawm hom vuam:
- Hom E (ERW)yog lub neej ntawd rau galvanized stock yeeb nkab los ntawm NPS 1/2 "nce txog 12". Qhov no yog dab tsi feem ntau cov neeg xa khoom xa tuaj thaum tus neeg siv khoom tsuas yog thov rau "galvanized yeeb nkab" yam tsis tau hais txog hom vuam.
- Hom S (seamless)galvanized muaj tab sis feem ntau yog ib qho kev txiav txim tshwj xeeb - seamless mills khiav dub yeeb nkab los ntawm lub neej ntawd, thiab galvanizing yog ntxiv raws li cov txheej txheem thib ob, uas ntxiv cov sij hawm txhuas.
- Hom F (qhov cub taub qab-welded, nruam vuam)yog txwv rau Qib A, NPS 4 "thiab qis dua, thiab yuav luag tsis pom nyob qhov twg tsuas yog ib qho kev lag luam tshwj xeeb:chain- txuas laj kab ncej- sab saum toj rail thiab kab ncej. Yog hais tias tus laj kab tus neeg cog lus spec hu tawm "Hom F galvanized," qhov no yeej yog vim li cas. Sab nraum lub laj kab, Hom F galvanized yeeb nkab tsis tshua muaj cov khoom lag luam thiab cov neeg yuav khoom nrhiav nws rau lub siab lossis cov qauv siv feem ntau yog nrhiav cov khoom tsis raug.
Qhov twg Galvanized A53 yeeb nkab yog qhov tseeb
- Hluav taws kub sprinkler systems- galvanized yog teev rau qhuav- yeeb nkab thiab ua ntej- cov tshuab ua haujlwm, cov qauv chaw nres tsheb, thiab cov chaw tsis muaj cua sov los yog lub freezer warehouse qhov chaw uas condensation los yog av noo yuav corrode dub yeeb nkab; ntub-cov kav dej hauv qhov chaw txias sab hauv feem ntau nyob nrog cov yeeb nkab dub ib NFPA 13 kev taw qhia thiab nqi.
- Sab nrauv structural thiab fencing ua haujlwm- saw- txuas laj kab kab ncej, sab saum toj rail, thiab rooj vag ncej (feem ntau Hom F raws li sau tseg saum toj no); guardrail thiab handrail rau sab nraum zoov taug kev, ramps, thiab platforms.
- HVAC thiab cov kav dej txhua yam hauv qhov chaw raug lossis sab nraum zoov- Cov khoom siv hauv tsev txhawb nqa, cov kab condensate khiav tawm sab nraum lub tsev ntawv lub tsev.
- Kev ua liaj ua teb- tsiaj txhu fencing, tsev cog khoom thiab hoop-tsev framing, rooj vag thiab corral tsim.
- Scaffolding thiab ua haujlwm ib ntus- raj raug huab cua nyob rau hauv lub neej ntawm ib qhov project, rov qab siv dua nyob rau hauv ntau qhov chaw ua hauj lwm qhov twg corrosion kuj ncua kev pab cuam lub neej.
Cov Ntaub Ntawv Tsim Nyog Paub: Galvanized tsis zoo ib yam li "Kho Txhua Yam"
Ib qho kev sib xyaw ua ke thiab kim heev- nce: tus neeg ua haujlwm kav dej qhia cov yeeb nkab A53 galvanized rau cov khoom siv hauv tsev tshiab vim "galvanized resists xeb." Hauv kev xyaum, feem ntau cov kav dej tam sim no thiab cov qauv kev taw qhia tau txav deb ntawm galvanized steel rau cov kav dej tshiab - internal tuberculation (mineral thiab corrosion buildup nyob rau hauv cov yeeb nkab bore) txwv tsis pub ntws thiab tuaj yeem paug cov dej tsis zoo nyob rau ntau xyoo ntawm kev pabcuam, uas yog hom tsis ua haujlwm sib txawv dua li sab nrauv xeb lub galvanizing yog los tiv thaiv. Copper, PEX, lossis CPVC tam sim no yog lub neej ntawd rau daim ntawv thov ntawd hauv feem ntau cov cheeb tsam; galvanized steel lub zog tiag tiag yog atmospheric thiab sab nrauv corrosion kuj, tsis ntev -lub sij hawm sab hauv dej. Nyeem ib daim ntawv spec lub txheej hnyav yam tsis tau kuaj xyuas seb qhovdaim ntawv thov nws tus kheejtseem yog ib qho tsim nyog siv rooj plaub yog qhov uas qhov kev tsis sib haum no pib.
Cov lus nug nquag nug (FAQ)
Q: Puas yog galvanizing txo qhov ntsuas siab ntawm A53 yeeb nkab?
A: Tsis yog. Cov txheej txheem hnyav yog cais los ntawm cov yeeb nkab lub siab tsim - kev ntsuas siab yog tswj hwm los ntawm phab ntsa tuab, qib, thiab sab nraud txoj kab uas hla ntawm ASME B31 cov qauv tsim, tib txoj kev nws yuav yog rau cov yeeb nkab dub ntawm tib qhov ntev.
Q: Can galvanized A53 yeeb nkab yuav welded rau ntawm qhov chaw?
A: Nws tuaj yeem ua tau, tab sis vuam kub hnyiab tawm ntawm zinc txheej hauv tshav kub- cuam tshuam thaj chaw thiab tso cov pa hluav taws xob zinc, uas yuav tsum tau ua kom muaj cua thiab tiv thaiv ua pa. Ntau qhov tshwj xeeb hu rau txias-galvanizing compound yuav tsum tau siv rau thaj tsam weld tom qab kom rov qab tiv thaiv corrosion, txij li re-dipping ib lub yeeb nkab ntsia tsis zoo.
Q: Puas yog Hom F galvanized yeeb nkab haum rau lwm yam uas tsis yog fencing?
A: Feem ntau tsis yog. Nws lub qab nthab loj (NPS 4 "thiab qis dua), Qib A- tsuas yog cov khoom siv kho tshuab, thiab txuas ntxiv- cov txheej txheem vuam ua rau nws qis dua - cov khoom siv zog rau lub teeb- lub luag haujlwm, tsis yog - daim ntawv thov siab - lub laj kab yog qhov yuav luag txhua qhov kev thov tam sim no rau nws los ntawm.
Q: Kuv yuav ua li cas thiaj paub tseeb tias qhov tseeb zinc txheej hnyav ntawm cov khoom xa tuaj?
A: Nug rau daim ntawv ntsuam xyuas zeb uas qhia qhov hnyav - ntawm - txheej ntsuas qhov ntsuas (lossis sib nqus tuab ntsuas hloov mus rau txheej hnyav) tawm tsam 1.8 oz / ft² nruab nrab / 1.6 oz / ft² yam tsawg kawg nkaus - cov duab duab. Daim ntawv qhia "kub-dip galvanized" uas tsis muaj tus lej tsis txaus los lees paub A53 ua raws.
