Cov hauv qab no qhia txog ntau yam kev kho saum npoo ntawm stainless hlau ncaj seam welded kav.
1. Mechanical polishing
Mechanical polishing yog ib txoj kev kho saum npoo av rau cov kav hlau stainless longitudinal welded kav. Los ntawm kev siv cov tshuab sib tsoo thiab cov khoom siv abrasive, cov nplais oxide thiab vuam cov cim ntawm cov yeeb nkab tau raug tshem tawm los txhim kho nws qhov chaw tiav. Txhua yam polishing tuaj yeem tshem tawm cov av thiab oxides ntawm qhov chaw ntawm stainless hlau ncaj seam welded kav, txhim kho corrosion kuj thiab zoo nkauj ntawm cov kav dej.
2. Pickling
Pickling yog ib txoj hauv kev uas feem ntau siv rau saum npoo ntawm stainless hlau ncaj seam welded kav. Los ntawm soaking stainless hlau ncaj seam welded kav hauv cov kua qaub, cov nplai thiab av ntawm cov yeeb nkab tuaj yeem raug tshem tawm. Pickling tuaj yeem du nto ntawm cov yeeb nkab thiab txhim kho nws cov corrosion kuj. Txawm li cas los xij, thaum lub sij hawm pickling, yuav tsum tau them nyiaj mloog mus rau kev tswj lub sij hawm pickling thiab kub kom tsis txhob muaj corrosion ntawm cov yeeb nkab.
3. Electrochemical polishing
Electrochemical polishing yog ib txoj kev kho saum npoo zoo rau cov kav hlau stainless longitudinal welded kav. Los ntawm kev siv hluav taws xob tam sim no hauv electrolyte, oxide nplai thiab vuam cov cim ntawm qhov chaw ntawm cov yeeb nkab raug tshem tawm, ua rau lub ntsej muag du. Electrochemical polishing tuaj yeem txhim kho corrosion kuj thiab zoo nkauj ntawm stainless hlau ncaj seam welded kav, thiab tuaj yeem txhim kho cov khoom siv ntawm cov kav dej.
4. Txheej kev kho mob
Txheej kev kho mob yog ib qho kev kho mob feem ntau siv rau stainless hlau ncaj seam welded kav. Los ntawm kev thov ib txheej ntawm cov xim pleev xim rau ntawm qhov chaw ntawm cov yeeb nkab, qhov corrosion kuj ntawm cov yeeb nkab tuaj yeem txhim kho. Cov txheej txheem sib txawv tuaj yeem raug xaiv rau kev kho cov txheej txheem, nyob ntawm qhov yuav tsum tau ua ntawm ib puag ncig siv tshwj xeeb. Ua ntej txheej txheej kho, cov yeeb nkab yuav tsum tau ntxuav thiab polished kom ntseeg tau tias qhov adhesion thiab sealing ntawm txheej.
5. Annealing tom qab vuam
Tom qab-weld annealing yog ib qho kev kho saum npoo av rau stainless hlau ncaj seam welded kav. Tom qab cov yeeb nkab welding tiav lawm, annealing ntawm qhov kub thiab txias tuaj yeem tshem tawm qhov kev ntxhov siab thiab deformation hauv qhov chaw vuam thiab ua kom cov yeeb nkab nto du. Post-weld annealing tuaj yeem txhim kho corrosion kuj thiab txhua yam khoom ntawm stainless hlau ncaj seam welded kav.
