Ob chav -Sided Galvanized Seamless Steel Yeeb Nkab
Ob chav -sab galvanized seamless steel yeeb nkabyog seamless carbon steel yeeb nkab uas tau txais kub -dipped zinc txheej ntawm ob lubsab nraud thiab sab hauv. Cov yeeb nkab seamless tshem tawm cov kab txuas txuas ntev, muab cov phab ntsa zoo ib yam thiab cov bore du, thaum cov zinc txheej sab hauv tiv thaiv cov yeeb nkab los ntawm cov kua dej sab - kev sib xyaw ua ke tau teev tseg rau kev siv dej, kev tiv thaiv hluav taws thiab kev siv cov txheej txheem uas ob tog raug corrosion.
Vim li cas Galvanize Sab Hauv Zoo?
Nyob rau hauv feem ntau galvanized yeeb nkab kev pab cuam, sab nrauv nto ntsib av, huab cua los yog av noo, thaum lub bore ntsib dej los yog txheej txheem kua. Yog tias tsuas yog sab nraud yog coated, sab hauv rusting tuaj yeem txo qhov muaj peev xwm txaus, paug cov dej thiab nws thiaj li perforate phab ntsa. Muab ob npaug rau-sab galvanizing ncua kev pab cuam lub neej los ntawm kev tiv thaiv ob qho tib si corrosion pem hauv ntej, thiab zinc tus cwj pwm fij tus neeg tiv thaiv txiav xov thiab qhov chaw puas.
Txheej txheem thiab txheej yuav tsum tau
Kev npaj:
cov yeeb nkab seamless yog degreased, pickled thiab fluxed yog li cov zinc molten ntub cov hlau ntawm ob qhov chaw.
Kub-dip immersion:
cov yeeb nkab yog immersed nyob rau hauv molten zinc ntawm roughly 450 degree; cov zinc- hlau alloy txheej tsim ib daim ntawv cog lus metallurgical.
Txheej hnyav:
feem ntau 300-600 g / m² nyob ntawm tus qauv thiab kev pabcuam; txheej txheej sab hauv yuav raug teev cais.
Kev txheeb xyuas:
txheej hnyav ib chav tsev, uniformity (piv txwv li, Preece test), adhesion thiab kev ywj pheej los ntawm liab qab pob yog kuaj raws li tus qauv siv.
Base Pipe Kev txiav txim siab
Cov yeeb nkab seamless yog tsim los rau cov qauv xws li GB / T 8163, ASTM A106 lossis EN 10216, nrog rau cov neeg kho tshuab yuav tsum tau kuaj xyuas ua ntej galvanizing. Galvanizing kub yog qis dua qhov normalizing ntau yam, yog li cov khoom siv kho tshuab yog qhov tseem ceeb khaws cia; tseem, daim ntawv pov thawj zeb sau cov kev sim cov yeeb nkab hauv qab thiab cov txheej txheem kev sim ua ke.

Cov lus nug nquag nug (FAQ)
Ob -sided galvanizing txhais li cas?
Qhov kub-dip zinc txheej yog siv rau ob qho tib si sab nraud thiab sab hauv ntawm cov yeeb nkab, tiv thaiv nws ntawm corrosion ntawm ob sab.
Puas yog txheej txheej sab hauv tuab li sab nraud?
Tsis yog ib txwm - txheej txheej sab hauv feem ntau tau teev tseg nyias (feem ntau sib dua lossis hnyav dua nyob ntawm cov kua), thiab ob qho tib si raug txheeb xyuas los ntawm kev ntsuas qhov hnyav.
Ob -sab galvanized yeeb nkab puas tuaj yeem welded?
Yog lawm, tab sis cov zinc hlawv tawm ntawm qhov vuam thiab yuav tsum tau rov qab nrog zinc- nplua nuj xim; welding zinc tsim fumes, yog li qhov cua yog qhov yuav tsum tau ua.
Puas yog seamless puag yeeb nkab muaj zog dua welded?
Seamless tsis muaj vuam seam thiab kev sib koom ua haujlwm ntawm 1.0; rau tib qib, nws phab ntsa yog homogeneous nyob ib ncig ntawm tag nrho cov ncig.
Puas yog galvanizing cuam tshuam qhov ntsuas siab?
Tsis muaj - qhov ntsuas siab yog teeb tsa los ntawm qib steel qib thiab phab ntsa tuab; zinc txheej muab kev tiv thaiv corrosion nkaus xwb.
Cov qauv siv li cas?
Txheej ua raws li kub-dip galvanizing qauv xws li ASTM A123 lossis ISO 1461, thiab cov yeeb nkab seamless ua raws nws tus qauv khoom nrog daim ntawv pov thawj zeb.
