Koj puas paub cov ntaub ntawv no hais txog kub-dip galvanized kav?

Nyhav coefficient
Nominal wall thickness (mm): 2.0, 2.5, 2.8, 3.2, 3.5, 3.8, 4.0, 4.5.
Coefficient parameters (c): 1.064, 1.051, 1.045, 1.040, 1.036, 1.034, 1.032, 1.028.
Nco tseg: Cov khoom siv mechanical ntawm cov hlau yog qhov ntsuas tseem ceeb kom ntseeg tau tias qhov kawg kev ua tau zoo (cov khoom siv kho tshuab) ntawm cov hlau. Nws nyob ntawm cov tshuaj lom neeg muaj pes tsawg leeg thiab kho cua sov ntawm cov hlau. Hauv cov qauv yeeb nkab steel, cov khoom siv tensile (tensile zog, muaj zog thiab cov txiaj ntsig nyuaj thiab cov khoom siv tawv me me thiab cov khoom siv kub.
Cov Qib Steel: Q215A; Q215b; Q235A; Q235b.
Ntsuam xyuas tus nqi / MPA: D10.2-168.3mm yog 3MPA; D177.8-323.9mm yog 5MPA

Rust tshem tawm txoj kev
1. Kev siv thawj zaug siv cov kuab tshuaj kom ntxuav cov npoo ntawm cov hlau kom tshem tawm cov teeb meem organic rau saum npoo.
2. Tom qab ntawd siv xeb tshem tawm cov cuab yeej (hlau txhuam) kom tshem tawm xoob lossis qaij nplai, xeb, thiab lwm yam.
3. Siv pickling.
Galvanizing tau muab faib ua cov plating kub thiab plating txias. Kev plating kub tsis yooj yim rau xeb, thaum lub sijhawm txias plating yog yooj yim rau xeb.
