GALVANIZED STEEL PIPE ELECTRIC RESISTANCE WELDED STEEL PIPE
Kev piav qhia
Galvanized steel yeeb nkab yog ib hom steel yeeb nkab uas tau coated nrog ib txheej ntawm zinc los tiv thaiv corrosion.Cov txheej txheem galvanization yuav immersing lub steel yeeb nkab nyob rau hauv ib da dej ntawm molten zinc, uas tsim ib tug kev sib raug zoo ntawm zinc thiab hlau, tsim ib tug tiv thaiv txheej ntawm nws nto.
Galvanized steel kav yog feem ntau siv nyob rau hauv ntau yam kev siv, nrog rau cov kav dej, kev tsim kho, thiab chaw tsim khoom.Lawv muaj zog thiab ruaj khov, thiab lawv cov galvanized txheej muab zoo heev tiv thaiv xeb thiab corrosion, ua rau lawv zoo tagnrho rau siv nyob rau hauv sab nraum zoov ib puag ncig.
Galvanized steel kav los ntawm ntau qhov ntau thiab tsawg thiab tuab kom haum rau kev siv sib txawv.Lawv tuaj yeem siv rau cov kav dej, cov kav dej, thiab lwm yam kev siv kav dej, nrog rau kev txhawb nqa thiab laj kab.
Galvanized seamless mechanical zog
Cov khoom siv hluav taws xob ntawm cov hlau yog los xyuas kom meej tias qhov taw qhia tseem ceeb ntawm cov khoom siv steel kawg (cov khoom siv tshuab), nws nyob ntawm cov tshuaj muaj pes tsawg leeg thiab kev kho cua sov ntawm cov hlau.Cov qauv hlau, raws li cov kev cai sib txawv, cov kev cai ntawm tensile zog (lub zog tensile, yield zog los yog yield point elongation) thiab hardness, toughness, neeg siv yuav tsum tau, siab thiab tsis kub kev ua tau zoo.

Siv
Galvanized Steel yeeb nkab raws li txheej txheej los ntawm galvanized yog dav siv rau ntau yam kev lag luam xws li architecture thiab tsev, mechanics (lub sijhawm no suav nrog kev ua liaj ua teb, roj av tshuab, prospecting machinery), tshuaj lom neeg kev lag luam, hluav taws xob fais fab, thee mining, railway tsheb, tsheb kev lag luam, txoj kev loj thiab choj, chaw ua kis las thiab lwm yam.
Painting & Txheej
Qhov xwm txheej ntawm cov raj galvanized
Thawj txheej - electrolytically leached zinc (Zn) - ua raws li anode thiab nyob rau hauv ib tug corrosive ib puag ncig nws corrodes ua ntej thiab lub hauv paus hlau yog cathodically tiv thaiv corrosion.zinc txheej thickness yuav nyob rau hauv thaj tsam ntawm 5 mus rau 30 micrometers (µm).
