API 5L Txheej Txheej Txheem Hlau Yeeb: Lub Ntiaj Teb Txheej Txheem Rau Kev Tiv Thaiv Zog
Q235b yog aCarbon txheem hlau qauv hlauQib nyob Suav teb tus qauv GB / T 700, nrog cov yam ntxwv tseem ceeb ntawm kev tawm los lub zog ntawm tsis tsawg tshaj li ntawm 235mpa thiab cov roj teeb manganese. Piv nrog dog dig Q235, Q235B yuav tsum dhau 20 degree cuam tshuam kev ntsuas kom ntseeg tau tias qhov tawv ntawm cov khoom ntawm chav tsev. Nws yog qhov tsim nyog rau archectural thiab cov tshuab tsim nrog cov kev xav tau pom tseeb rau cov khoom siv neeg kho kom zoo nkauj, thiab yog cov khoom lag luam dav dav rau cov kev lag luam.
Qhov sib txawv ntawm API 5L PSL1: theem pib thiab qib siab
API 5L muab faib ua ob qib, PSL1 thiab PSL2. PSL1 yeeb nkab yog haum rau cov kev pab cuam dav dav, nrog cov kev xav tau xoob, thiab yog siv tsawg-siab. PSL2 yuav tsum muaj cov roj ntsha sib xyaw ua ke, ntau dua kev sim siab, thiab yog qhov tsim nyog ua kom muaj kev pheej hmoo, xws li kev sib tsoo-hiav txwv lossis xim polar.
Qhov sib txawv ntawm API 5L PSL2: Qhov Kawg Hauv Kev Ua Haujlwm Zoo
PSL2 cov yeeb nkab steel txuas ntxiv txhawb kev ua tau zoo los ntawm psl1 sib npaug kev ntsuas Carbon ntau (DWTT) kom ntseeg tau tias cov yeeb nkab tsis kam mus rau qhov qis qis ntawm qis lossis kub. Nyob rau tib lub sijhawm, PSL2 cov kav hlau hlau yuav tsum muaj cov kev sim ua kom muaj kev ua kom muaj kev tiv thaiv tsis pub muaj qhov tsis raug.
Kev Siv Khoom Siv: Cov Kev Pab Nyiaj Tag Nrho Cov Teeb Meem
API 5L STEEL YEEB NKAByog dav siv nyob rau hauv av thiab dej hiav txwv roj thiab roj kis. PSL1 feem ntau yog siv rau cov kav dej tsis tshua muaj siab thiab luv luv, kev daws teeb meem deb thiab muaj kev nyab xeeb rau cov kev sib raug zoo rau ntiaj teb.
