Q235 Galvanized Welded Hlau Yeeb Nkab & Tube
Taw qhia rau Q235 Galvanized Ncaj Seam Welded Yeeb Nkab
Q235 yog ib hom carbon steel qauv nrog lub zog tawm ntawm kwv yees li 235 MPa, uas yuav txawv nrog cov khoom tuab. Tshwj xeeb tshaj yog, galvanized Q235 steel kav tsis tas yuav tsum tau ua tshwj xeeb xws li preheating los yog post-welding thaum tshav kub kub kev kho mob. Lawv muab cov txiaj ntsig zoo xws li kev ua tau zoo, kev ua tau zoo, tus nqi -kev ua tau zoo, thiab kev ua haujlwm siab- rau- tus nqi piv. Q235 steel kav yog muaj zog, ruaj, yooj yim rau vuam, thiab muaj cov yas zoo heev. Lawv tuav lawv lub zog txawm tias thaum khoov ntawm qhov kub qis. Cov galvanized Q235 steel kav no tau siv dav hauv engineering thiab kev tsim kho, npog cov ntawv thov xws li cov chaw tsim khoom, cov khoom siv ntxiv, cov yees, boilers, txuas hniav, ntim, tsheb, thiab ntau yam welded qauv uas tau txais txiaj ntsig los ntawm kev ua haujlwm ntawm Q235 steel. Tsis tas li ntawd, Q235 cov qauv steel kav kuj tseem siv tau los ua cov khoom siv tshuab.

Galvanizing txheej txheem ntawm Q235 Galvanized welded yeeb nkab
Cov txheej txheem galvanizing tseem ceeb rau Q235 galvanized welded yeeb nkab suav nrog cov khoom siv dav tshaj plaws kub-dip galvanizing thiab cov khoom siv hluav taws xob ntau dua-galvanizing. Kub-dip galvanizing yuav immersing lub welded yeeb nkab nyob rau hauv molten zinc ntawm kwv yees li 450 degree, ua ib tug muaj zog-adhesion alloy txheej nrog ib tug tuab ntawm 45-100μm ntawm nws nto, muab zoo heev corrosion kuj. Electro-galvanizing, ntawm qhov tod tes, siv electrolysis los ua ib qho zoo, du, tab sis nyias zinc txheej ntawm cov yeeb nkab steel, ua rau nws tsim nyog rau cov ntawv thov uas xav tau siab precision ntawm qhov tsos thiab qhov ntev, thiab nyob rau hauv ib puag ncig me me corrosive. Tam sim no, kub-dip galvanizing tau dhau los ua cov txheej txheem kev kho mob tseem ceeb rau cov khoom lag luam no vim nws qhov ua tau zoo thiab ua haujlwm tau zoo.
