1. Dab tsi yog qhov qauv no?
Nace sawv rau lub koom haum hauv lub teb chaws ntawm corrosion engineer koom tes {} Tus qauv kav hlau hauv cov roj thiab roj kev lag luam.
2. Dab tsi yog cov yam ntxwv ntawm api 5l gr . nace steel yeeb nkab?
API 5L Gr . b psl {}}}}} Cov kab hlau no ua kom zoo rau cov khoom lag luam steel dua li phsl -2. Cov ntsiab lus ntawm cov pa roj carbon mon} Cov pa roj hmab muaj tsawg kawg yog 245mpa {{} nyob rau tib yam lub sij hawm, cov yeeb nkab steel siv rau hauv cov txiaj ntsig kev cuam tshuam ntawm cov tub ceev xwm xws li hyss thiab tsim kom haum rau cov roj hnyav thiab roj av ib puag ncig.
3. Dab tsi yog qhov uas yuav tsum muaj ntawm Nace tus qauv rau cov yeeb nkab steel ua haujlwm?
Corrosion Kuj: Cov kav hlau steel yuav tsum muaj peev xwm tiv thaiv corrosion hauv cov qauv kev ncaj ncees thiab cov pa roj teeb uas muaj cov xov xwm corrosive .
Tshuaj lom neeg tshuaj lom neeg tswj: Txwv cov ntsiab lus ntawm cov ntsiab lus hauv cov xees steel uas yuav cuam tshuam rau corrosion ntawm cov yeeb nkab corrosion sib xws li .
Cov khoom siv neeg kho tshuab: Lub zog tshwj xeeb tensile thiab elongation lub zog yuav tsum tau ua kom pom cov chaw ib puag ncig, qhov kev xav tau kub me me
Kev kuaj sim thiab ntawv pov thawj: Cov kev xeem ntawv yuav tsum dhau, thiab tsis txwv rau cov kev sim ua kom xeb (hic) kev sib tsoo, thiab xeb kev ua haujlwm, thiab corrosion rogption {}}
Kev Tsim Kho Cov Txheej Txheem: Tswj txoj kev tsim khoom ntawm cov kav hlau tsim, ua kom muaj kev kho cua sov, kom ntseeg tau tias cov kav hlau ua haujlwm ntawm cov kav hlau ua si, kom ntseeg tau tias cov kav hlau ua haujlwm ntawm cov kav hlau sib txawv
4. Dab tsi yog qhov sib txawv hauv cov chaw muaj peev xwm thaum PSL {} thiab ps1-2 tab tom ua ke nrog nace hauv api 5l tus qauv?
Psl -1: Siv tau rau cov kev siv txheem thiab cov pa hluav taws xob nrog rau cov qauv nace tab sis tus nqi qis dua.
Psl -2: Siv tau rau cov roj av uas muaj kev sib xyaw nrog cov roj av ntau, nws tuaj yeem ua ke nrog cov pa hluav taws kub
5. Dab tsi yuav tsum tau txiav txim siab thaum xaiv API 5L steel kav uas ntsib NACE cov qauv?
Consider the specific application requirements and budget when choosing. If the project is in a general environment with less severe corrosion and is more sensitive to cost, PSL-1 grade steel pipes can be selected; Yog tias txoj haujlwm no yog nyob rau hauv ib qho nyuaj, muaj kev sib zog ua kom ncaj ncees, tab sis tus nqi ntawm permes ntawm cov kav hlau steel
