304 stainless hlau tuab-walled rajweld sib piv ua ntej thiab tom qab kev kho deg thiab kev ua tiav qhia tau hais tias: txoj kev no tuaj yeem tshem tawm cov nplai thiab kub xim.

Thaum tib neeg tsa 304 stainless hlau tuab-walled tube nto oxide txheej ntawm chromium oxide cov ntsiab lus, cov qauv ntawm oxide txheej tom qab kev ua kom zoo, koj tuaj yeem txhim kho kev ua haujlwm zoo ntawm 304 stainless hlau tuab-walled raj nto.Los ntawm cov txheej txheem kev kho tshuaj kom ua tiav 304 stainless hlau tuab-walled raj los txhim kho corrosion kuj ntawm qhov chaw hauv ob kauj ruam.Txawm tias 304 stainless hlau tuab-walled raj vuam los ntawm txoj kev no kuj tuaj yeem siv los txhim kho nws cov corrosion kuj.

Thaum 304 stainless hlau tuab-walled raj nto corrosion kuj tsis txaus, tus kws kho deg tshwj xeeb Poligrat Munich lub tuam txhab tsim Polinox Protec TC thev naus laus zis tuaj yeem pab koj daws qhov teeb meem no.Cov cuab yeej siv tshuab no thiab cov chaw muag tshuaj tau tsim cov thev naus laus zis los txhim kho cov nickel, molybdenum thiab chromium austenitic alloy khoom, yog li txhim kho corrosion kuj ntawm 304 stainless hlau tuab-walled raj nto.Los ntawm ob kauj ruam tuaj yeem nce 304 stainless hlau tuab-walled tube nto oxide txheej ntawm corrosion kuj.

Thawj kauj ruam hauv kev siv dej-raws li cov organic tov ntawm 304 stainless hlau tuab-walled raj nto yog nto-kho.Qhov kev kho saum npoo no yuav kav 3 ~ 5h.Lub sijhawm no, tshem tawm cov oxide txheej los ntawm qhov chaw ntawm cov hlau, nrog rau kev txo cov hlau, chromium thiab hlau piv tau nce los ntawm 6% mus rau 8%, mus rau lub luag haujlwm tseem ceeb hauv kev txhim kho corrosion kuj muaj.

Qhov thib ob kauj ruam los txhim kho cov qauv ntawm cov txheej txheem oxide nto.Qhov no ntxiv txhim kho corrosion kuj ntawm oxide txheej txheej.Kev cuam tshuam rau cov qauv ntawm cov txheej txheej oxide saum npoo yog txheej txheem kev kho cua sov ntawm: raws li hom alloy thiab kev kho cua sov ntawm cov khoom siv lead ua lattice ntawm cov khoom hauv huab cua ntawm 140℃~ 200℃hauv.
