S355J2WP tuaj yeem hloov ASTM A588Txog kev siv hluav taws xob hlau siv, tab sis qhov sib txawv tseem ceeb hauv kev sib xyaw, kev sim, thiab cov qauv kev cai lij choj yuav tsum txiav txim siab. Ntawm no yog cov ncauj lus piav qhia:
1. Cov ntsiab lus tseem ceeb
Huab Cua Kev Ua Haujlwm: Ob daim ntawv tiv thaiv Patinas (CU / CR / POLE
Lub zog kawm qib:
Tos lub zog: ntau dua lossis sib npaug zos rau 355 mpa (s355j2wp) vs. ntau dua lossis sib npaug ntawm 345 mpa8).
Lub zog tensile: 470-630 MPa (ob qho tib si).
2. Tseem cuam tshuam sib txawv

3. Hloov cov xwm txheej

Ua rawsCov Qauv European(piv txwv li, EU Infrastructure).

Tsis pom zoo thaum:
North Anch ProjectQhia kom meej Astm A588 rau kev tswj hwm ua raws li kev cai.
Nqi Sensitivity: A588 yuav pheej yig dua nyob rau qee lub khw vim tias dav ntau lawm.
Thickness >100 hli: A588 muaj cov kev xaiv qib ntxiv (piv txwv li, A588 qib K).
4. Cov lus pom zoo
Rau hloov ncaj qha hloov:

Nrhiav pov thawjCorrosion Performance index ntau dua los yog sib npaug rau 6.0(rau en) thiab CU / CR cov ntsiab lus (rau Astm).
Kev tsim kho kho kom haum:
Rov ua kom muaj kev ntxhov siab uas tau muab tso cai (A588 cov txiaj ntsig yog 10 MPA qis).
Txheeb xyuas Weld Cov Txheej Txheem (s355j2WP lub siab dua p / s txo kev phom sij).
Ntawv sau:
Cov qauv kev hla kev hauv cov qauv kev ua tiav docs (piv txwv li, "Astm A588 lossis EN 10055-5 s355j2Wp").
