Dab tsi yog Kub-Dip Galvanized ERW Round Pipe?
Lub hauv paus raj pib raws li ERW puag ncig cov yeeb nkab: tiaj tus steel sawb yog yob- ua rau hauv ib puag ncig thiab welded raws ib leeg ntev seam siv siab - zaus hluav taws xob tsis kam vuam. Cov txheej txheem no ua rau cov yeeb nkab ncaj nraim nrog nruj sab nraud - txoj kab uas hla thiab phab ntsa- thickness kam rau ua, uas tseem ceeb rau fencing thiab scaffolding vim fittings, clamps, thiab couplers yog me me rau kaw kam rau ua.
Tom qab lub raj tsim, txiav kom ntev, thiab (nyob ntawm lub zeb) kuaj rau kev ncaj ncees, nws tau ntxuav hauv cov kua qaub da dej kom tshem tawm cov nplai thiab oxidation, yaug, dipped hauv cov tshuaj flux, thiab tom qab ntawd muab tso rau hauv ib da dej ntawm molten zinc, feem ntau tuav ntawm 450℃(840 degree). Cov zinc reacts metallurgically nrog steel nto los ua ib tug series ntawm zinc - hlau alloy txheej topped nrog ib txheej ntawm kuj ntshiab zinc. Qhov no txawv ntawm electro-galvanizing, uas electroplates ntau thinner zinc txheej rau ntawm qhov chaw uas tsis muaj alloy sib txuas - kub-dip coatings yog thicker, ntau abrasion-resistant, thiab zoo haum rau cov yeeb nkab uas yuav tsum tau tsav mus rau hauv av, stacked, thauj, thiab rov qab siv dua nyob rau hauv lub chaw ua hauj lwm.
Vim li cas Kub-Dip Galvanizing Matters rau Fencing thiab Scaffolding
- Kev tiv thaiv corrosion los ntawm kev txi.Zinc corrodes nyiam tshaj rau hlau. Txawm hais tias qhov txheej txheej yog khawb los yog nicked thaum lub sijhawm teeb tsa, cov zinc nyob ib puag ncig tseem tiv thaiv cov hlau electrochemically, uas yog qhov zoo dua rau cov xim pleev xim los yog hmoov-coated yeeb nkab uas tsis muaj kev tiv thaiv thaum cov yeeb yaj kiab tawg.
- Txheej durability nyob rau hauv mechanical kev nyuaj siab.Lub laj kab ncej raug ntaus los ntawm cov tshuab txiav thiab tsheb; scaffolding raj tau poob, rub, thiab clamped txhua hnub. Lub metallurgically sib raug zoo zinc- cov txheej hlau tiv thaiv kev puas tsuaj thiab cuam tshuam zoo dua li qhov chaw- siv txheej, uas txo qhov muaj feem cuam tshuam ntawm cov hlau uas tsim cov xeb hauv thawj xyoo ntawm kev pabcuam.
- Ntev, qis-kev pabcuam tu lub neej.Nyob rau hauv cov huab cua raug raug, tus qauv kub-dip galvanized txheej tuaj yeem cia siab tias yuav kav ntev li ob peb xyoos ua ntej lub hauv paus hlau corrosion yuav muaj kev txhawj xeeb, uas yog vim li cas cov yeeb nkab galvanized tseem yog qhov kev xaiv rau thaj tsam fencing, saw- txuas kab posts, thiab kev tsim kho cov kab ke uas tsis tau pleev xim rau ntawm lub sijhawm.
- Zoo sib xws tsos thiab paintability.Freshly galvanized yeeb nkab muaj qhov ci, me ntsis spangled tiav uas ntau tus neeg yuav khoom siv raws li - yog rau laj kab. Qhov twg yuav tsum muaj xim tiav tom qab, qhov saum npoo kuj tuaj yeem raug primed thiab sab saum toj -coated thaum nws tau huab cua los yog tau kho nrog cov etching primer.
Cov qauv, Qib, thiab txheej hnyav
Cov neeg yuav khoom galvanized ERW yeeb nkab rau fencing thiab scaffolding feem ntau siv ib qho ntawm cov hauv qab no:
ASTM A53Hom E, Qib B- feem ntau US tus qauv rau galvanized ERW yeeb nkab, npog ob qho tib si lub hauv paus tube mechanical zog thiab, los ntawm kev siv, galvanizing yuav tsum.
Cov kub kub-dip txheej hnyav poob nyob rau hauv thaj tsam ntawm 350-600 g / m² ntawm tag nrho cov zinc kev pab them nqi, sib xws rau cov txheej tuab ntawm kwv yees li 45-85 microns nyob ntawm cov hlau seem thickness. Scaffold tube feem ntau yog tsim los rau me ntsis nruj dua txheej kam rau siab dua li cov laj kab dav dav vim tias nws tau rov qab siv dua nyob rau ntau qhov haujlwm thiab xav tau kom nws cov txheej txheem tiv thaiv los ntawm kev rov ua dua thiab rhuav tshem.
Qhov ntau thiab tsawg rau Fencing thiab Scaffolding
| Daim ntawv thov | Hom OD Range | Hom Phab Ntsa Thickness |
|---|---|---|
| Chain- txuas laj kab kab ncej | 48-60 hli (1.9 "- 2.375") | 1.8-2.75 hli |
| Chain- txuas laj kab sab saum toj rail | 33-42 hli (1.3 "- 1.66") | 1.5-2.0 hli |
| Guardrail / handrail systems | 42-48 hli (1.66 "-1.9") | 2.0-3.0 hli |
| Scaffold tube (BS 1139 txuj) | 48.3mm ib | 3.2-4.0 hli |
| Scaffold tube (lub luag haujlwm teeb) | 48.3mm ib | 2.9-3.2 hli |
Post thiab rail sizing yog nquag swaged (ib kawg txo nyob rau hauv txoj kab uas hla) kom sab saum toj rail slides rau hauv kab ncej fittings tsis cais couplers - buyers ordering laj kab- tshwj xeeb yeeb nkab yuav tsum tau qhia seb swaged xaus yog xav tau, txij li thaum swaging yog ib tug nyias muaj nyias haujlwm ntawm galvanizing.
Cov lus nug nquag nug (FAQ)
Q: Qhov txawv ntawm kub-dip galvanized thiab pre-galvanized (GI) yeeb nkab yog dab tsi?
A: Kub-dip galvanizing feem ntau yog siv tom qab lub raj tsim thiab txiav mus rau qhov kawg ntev, muab cov txheej txheem tag nrho ntawm kev txiav xaus thiab txhua qhov chaw kho weld. Pre-galvanized (GI) yeeb nkab yog tsim los ntawm steel sawb uas tau galvanized ua ntej nws yuav yob- ua rau hauv lub raj, uas txhais tau hais tias qhov kev txiav xaus thiab qhov weld seam cheeb tsam yuav muaj thinner los yog tsis muaj zinc pab tshwj tsis yog kov. Rau faus laj kab posts lossis scaffold tube raug cov dej noo ntawm qhov txiav xaus, kub -dip galvanizing tom qab fabrication feem ntau muab kev tiv thaiv corrosion zoo dua.
Q: Ntev npaum li cas kub -dip galvanized laj kab yeeb nkab nyob sab nraum zoov?
A: Kev pabcuam lub neej yog nyob ntawm qhov chaw nyob hauv cheeb tsam - ntug hiav txwv dej, kev lag luam, thiab de-icing- ntsev ib puag ncig corrode zinc sai dua li cov huab cua qhuav hauv av. Raws li cov lus qhia ntxhib, qhov zoo coated kub-dip galvanized ncej nyob rau hauv ib qho kev nyab xeeb nruab nrab tuaj yeem ua haujlwm tau ntau xyoo ua ntej xeb liab tshwm rau ntawm lub hauv paus hlau, txawm tias hnyav heev los yog cov chaw hauv hiav txwv yuav pom lub neej luv dua los ntawm tib txheej txheej hnyav.
Q: galvanized scaffold tube puas tuaj yeem rov siv tsis tau?
A: Tsis muaj txheej txheej yuav kav mus ib txhis hauv kev rov ua dua. Reputable scaffold ntiav thiab cov tuam txhab tsim kho tshuaj xyuas lub raj tsis tu ncua rau txheej poob, dents, thiab tawm - ntawm - roundness, retiring tube thaum liab qab steel yog pom tau pom nyob rau hauv ib cheeb tsam muaj txiaj ntsig lossis ib zaug phab ntsa thickness tau thinned los ntawm corrosion. Zoo- khaws cia kub-dip galvanized raj feem ntau pom ntau xyoo ntawm kev sib hloov siv ua ntej so haujlwm.
Q: Puas kub -dip galvanizing cuam tshuam rau cov yeeb nkab lub zog?
A: Cov txheej txheem galvanizing nws tus kheej tsis txhais tau tias hloov cov hlau tawm los yog lub zog tensile - qhov kev txiav txim siab tseem ceeb yog tias qhov da dej kub tuaj yeem cuam tshuam qee zaus cuam tshuam rau nyias - phab ntsa lossis siab - lub zog lub raj yog tsis tswj kom zoo, uas yog vim li cas cov txheej txheem zeb tswj qhov tseem ceeb rau cov ntu nyias. Standard laj kab thiab scaffold phab ntsa thicknesses yog unaffected nyob rau hauv ib txwm ntau lawm.
