Kev kho deg Ntawm Welded Steel Pipes

Galvanizing: Galvanizing yog ib qho kev kho deg tshwj xeeb tshaj yog tsim rau cov yeeb nkab steel siv nyob rau hauv ib puag ncig corrosive. Thaum lub sij hawm tus txheej txheem no, cov yeeb nkab steel yog soaked nyob rau hauv molten zinc, tsim ib tug zinc txheej. Cov zinc txheej no muab kev tiv thaiv corrosion zoo heev thiab tiv thaiv cov kav hlau los ntawm xeb. Galvanized steel kav yog siv dav hauv cov ntawv thov xws li cov kav dej, roj thiab cov kav dej, thiab lwm yam.

Txau Painting: Txau tha xim yog ib qho yooj yim txheej txheej txheej haum rau lub hom phiaj dav hlau welded steel yeeb nkab. Thaum lub sij hawm txheej txheem no, qhov saum npoo ntawm cov yeeb nkab yog ntxuav thiab derusted, ces ib txheej ntawm cov xim los yog tshuaj tsuag txheej yog siv los muab kev tiv thaiv thiab kev zoo nkauj.

Txheej: Ntxiv rau cov xim, welded steel kav kuj tuaj yeem coated nrog cov txheej tshwj xeeb los tiv thaiv corrosion. Cov txheej txheem no tuaj yeem xaiv tau raws li qhov yuav tsum tau ua ntawm daim ntawv thov tshwj xeeb. Piv txwv li, cov tshuaj tiv thaiv corrosion tuaj yeem yog epoxy, polyethylene, polyester, polyurethane thiab lwm yam ntaub ntawv.

Kub-dip galvanizing: Kub-dip galvanizing yog ib txoj kev ntawm immersing steel kav hauv molten zinc, zoo ib yam li galvanizing li niaj zaus. Tab sis tsis zoo li cov galvanizing zoo tib yam, kub-dip galvanizing yuav ua rau cov txheej txheem ntau dua thiab tuab, yog li nws muaj kev tiv thaiv corrosion zoo dua.

Peb-txheej polyethylene txheej (3PE): Qhov no yog txheej txheem txheej txheej tshwj xeeb siv rau cov kav dej hauv av. Nws muaj lub hauv paus txheej ntawm cov nplaum, nruab nrab polyethylene txheej, thiab txheej txheej txheej. 3PE txheej muab kev tiv thaiv corrosion zoo heev thiab tsim nyog rau qhov hnyav hauv av ib puag ncig.

Txhaj Peening: Hauv qee qhov tshwj xeeb daim ntawv thov, qhov chaw ntawm welded steel kav yog tua peened los ntxuav thiab tshem tawm cov av thiab xeb los ntawm qhov projecting hais (feem ntau yog hlau txhaj tshuaj los yog lwm yam ntaub ntawv nyuaj) ntawm high speeds.

Xaiv txoj kev kho kom haum rau saum npoo yog nyob ntawm kev siv tshwj xeeb, ib puag ncig thiab kev ua haujlwm ntawm cov yeeb nkab steel welded. Cov kev kho mob sib txawv tuaj yeem muab kev sib txawv ntawm kev tiv thaiv corrosion thiab kev tiv thaiv kom ntseeg tau tias cov yeeb nkab tswj kev ua tau zoo thiab kev ntseeg siab rau lub sijhawm ntev.
