Thaum lub caij ntuj sov kub heev, lub Hoobkas tab tom ua ntau yam haujlwm valve. Ob peb hnub dhau los, lub Hoobkas Jinbin tau ua tiav lwm qhov kev txiav txim los ntawm Iraq. Cov rooj vag dej no yog 304 stainless hlaurooj vag dej ntws tes, nrog rau lub pob tawb ntws dej stainless hlau 304 nrog txoj kev qhia 3.6-meter. Kev vuam ntawm lub qia valve raug ntxuav nrog ultrasonic acid kom tshem tawm cov xim av.

Kev siv cov khoom siv hlau tsis xeb 304 los tsim khoomlub pas dejmuaj cov txiaj ntsig zoo li nram no:

304 stainless hlau muaj ntau chromium thiab nickel, uas tuaj yeem tiv taus kev yaig ntawm ntau yam tshuaj lom neeg, suav nrog cov kua qaub, alkalis, thiab ntsev. Nws yog qhov tshwj xeeb tshaj yog rau cov chaw uas yuav kov cov dej phwj thiab dej hiav txwv, thiab tuaj yeem tswj tau qhov ruaj khov ntawm cov qauv thiab cov khoom siv kho tshuab hauv cov chaw kub siab, ua rau nws haum rau cov xwm txheej kub siab.

304 stainless hlau yooj yim ua thiab zoo nkauj, tsim nyog rau kev tsim ntau yam rooj vag uas muaj cov duab nyuaj, thiab yooj yim ua kom tau raws li qhov yuav tsum tau ua ntawm kev tsim kho. Cov khoom siv no muaj kev tiv thaiv kev hnav zoo, tuaj yeem tiv taus kev hnav thiab khawb, tswj qhov chaw du thiab zoo nkauj, thiab muaj lub zog thiab kev tawv ncauj ntawm chav tsev kub, ua kom ntseeg tau tias lub rooj vag muaj kev ntseeg siab thiab kev nyab xeeb hauv ntau yam kev siv engineering.

Qhov saum npoo ntawm 304 stainless hlau yog du thiab sib xws, nrog rau cov khoom zoo nkauj thiab zoo nkauj, tsim nyog rau cov ntawv thov uas xav tau siab rau qhov zoo li. Nws tuaj yeem tsim cov zaj duab xis oxide ntom ntom ntawm qhov chaw hauv huab cua, tiv thaiv cov hlau oxidation thiab xeb, thiab ntev lub neej kev pabcuam. Nws tsis muaj cov khoom siv hlau hnyav rau tib neeg lub cev, ua tau raws li cov qauv kev huv thiab kev nyab xeeb, tsim nyog rau kev ua zaub mov, cov khoom siv kho mob thiab lwm yam teb, yog cov khoom siv rov ua dua tshiab, yog tus phooj ywg ib puag ncig, thiab ua raws li lub tswv yim ntawm kev txhim kho kom ruaj khov. Vim yog qhov tsis kam tiv thaiv corrosion thiab hnav tsis kam ntawm 304 stainless hlau, tus nqi txij nkawm ntawm lub rooj vag yog qis dua.

Cov txiaj ntsig no ua rau 304 stainless hlau yog qhov kev xaiv zoo tshaj plaws rau kev tsim khoomcov kav dej ntawm phab ntsa, tshwj xeeb tshaj yog nyob rau hauv hydraulic engineering, dej phwj tuaj kho, thiab marine ib puag ncig, kom ntseeg tau tias kev ua haujlwm ruaj khov mus sij hawm ntev thiab kev saib xyuas qis ntawm lub rooj vag. Yog tias koj muaj ib qholub qhov rooj dej ntwscov khoom siv valve xav tau, thov hu rau peb hauv qab no thiab koj yuav tau txais lus teb tsis pub dhau 24 teev.
