1.Dab tsi yog kev kho deg lossis kev ua tiav feem ntau siv rau JIS G3466 cov kav dej, thiab vim li cas?
Tshaj qhov "dub" (mill scale) tiav, kev kho mob ntau heevkub-dip galvanizing(zinc txheej) rau kev tiv thaiv corrosion. Qhov hnyav ntawm zinc txheej yuav tsum tau (piv txwv li, Ntau dua lossis sib npaug li 80 g / m²) nyob ntawm ib puag ncig- siab dua rau thaj chaw ntug hiav txwv lossis chaw lag luam-1. Cov kav dej kuj tuaj yeem pleev xim lossis pleev xim rau ob qho tib si kev tiv thaiv thiab kev zoo nkauj.
2.Dab tsi yog qhov tseem ceeb ntawm kev kuaj xyuas thaum muab lossis tshuaj xyuas JIS G3466 kav?
Cov tshev tseem ceeb suav nrog:
Dimensional Verification:Xyuas kom qhov ntev thiab phab ntsa thickness yog nyob rau hauv raws li JIS kam rau ua.
Cov ntaub ntawv pov thawj:Tshawb xyuas daim ntawv pov thawj zeb xeem kom ua raws li qib yuav tsum tau muaj cov tshuaj lom neeg muaj pes tsawg leeg thiab cov khoom siv tshuab.
Kev tshuaj xyuas qhov muag:Tshawb xyuas qhov tsis xws luag xws li khawb tob, xeb ntau dhau, lossis deformities.
Txheej tshuaj ntsuam xyuas (yog tias muaj):Kev txheeb xyuas qhov sib xws thiab kev ua raws li galvanized lossis pleev xim tiav.
Ncaj nraim:Paub meej tias cov yeeb nkab tsis yog khoov los yog twist ntau dhau.
3.Dab tsi yog cov teeb meem uas tshwm sim los yog cov ntsiab lus ntawm kev tsis ua hauj lwm cuam tshuam nrog kev siv cov txheej txheem square raj hauv fabrication?
Cov teeb meem tshwm sim muaj xws li:
Vuam Defects:Cov txheej txheem vuam tsis raug ntawm cov ces kaum tuaj yeem ua rau muaj kev ntxhov siab thiab tawg ua ke -2. Siv cov txheej txheem kom raug thiab qee zaum ua ntej cua sov rau cov ntu tuab yog qhov tseem ceeb.
Localized Buckling:Nyob rau hauv qhov hnyav compressive loads, lub ntsej muag tiaj tus ntawm nyias - cov hlab ntsa tuaj yeem buckle hauv zos.
Corrosion ntawm Cut Ends:Yog tias cov kav dej galvanized raug txiav hauv thaj teb, cov npoo ntawm cov npoo yuav tsum tau kho kom zoo (xws li, nrog zinc- cov xim nplua nuj) kom tsis txhob xeb los ntawm qhov pib.
4.Rau cov phiaj xwm thoob ntiaj teb, qhov kev txiav txim siab yuav khoom dab tsi tshwj xeeb rau kev xa khoom JIS G3466 kav?
Cov ntsiab lus tseem ceeb yog:
Ntawv pov thawj:Xyuas kom cov chaw tsim khoom tuaj yeem muab cov ntawv pov thawj JIS cov ntaub ntawv pov thawj thiab cov ntaub ntawv soj ntsuam mills.
Cov qauv sib npaug:Qhia meej nrog tus kws ua haujlwm ua haujlwm yog JIS G3466 raug yuam lossis yog "lossis sib npaug" kab lus lees txais ASTM / EN cov qauv siv.
Lub Sijhawm Lead thiab Logistics:Factoring nyob rau hauv manufacturing thiab shipping lub sij hawm, tshwj xeeb tshaj yog rau kev cai ntau thiab tsawg los yog ntau ntau.
Supplier Capability:Kev ntsuas tus neeg muag khoom lub peev xwm los muab qhov zoo ib yam, ua tiav cov ntaub ntawv, thiab txhim khu kev qha tom qab -kev txhawb nqa muag-1.
5.Qhov kev ua tau zoo ntawm JIS G3466 STKR400 yeeb nkab nyob rau hauv dabtsi yog khoov txawv ntawm cov yeeb nkab zoo sib xws?
Lub raj square / duab plaub muaj lub sijhawm sib txawv ntawm inertia (cov cuab yeej geometric cuam tshuam rau qhov nruj) piv rau cov yeeb nkab puag ncig ntawm qhov hnyav sib xws.Square tubes feem ntau muab ntau dua dabtsi yog khoov nruj nyob rau hauv cov kev taw qhia parallel rau lawv sab, ua rau lawv muaj txiaj ntsig zoo li kab teeb. Txawm li cas los xij, cov kav dej puag ncig muaj qhov sib txawv ntawm txhua qhov kev taw qhia thiab feem ntau zoo dua rau torsional (twisting) rog. Qhov kev xaiv nyob ntawm seb hom kev thauj khoom uas tus tswv cuab yuav nqa.
