Q1: Cov qib ob puas tuaj yeem siv rau galvanizing?
A:Yog lawm, ASTM A53 tus qauv suav nrog cov kev cai rau ob qho tib si dub thiab kub -dipped galvanized steel yeeb nkab rau ob qib -1-9.
Q2: Dab tsi yog qhov hloov tshiab tseem ceeb hauv ASTM A53 2024 version?
A:Ib qho kev hloov tshiab tseem ceeb hauv xyoo 2024 yog qhov kev tso cai los tsim Qib B rauv-Butt Welded (Hom F) kav, nthuav dav ntau yam ntawm cov ntawv thov rau tus nqi no- kev xaiv zoo -9.
Q3: Cov cuab yeej elongation piv li cas ntawm cov qib?
A:Qhov tsawg kawg nkaus elongation yuav tsum yog xam los ntawm cov qauv raws li lub zog tensile thiab cov qauv ntoo khaub lig-sectional cheeb tsam. Txij li thaum Gr.B muaj lub zog tensile ntau dua, nws qhov ntsuas qhov tsawg kawg nkaus elongation tus nqi rau tib qhov loj me yuav qis dua me ntsis rau GrA, txawm hais tias ob qho tib si yog ductile -9.
Q4: Hauv qhov project specification, "A53 Gr.B, Hom E" txhais li cas?
A:Qhov kev xaiv no qhia txog cov yeeb nkab uas ua tau raws li cov khoom siv tshuaj lom neeg thiab cov khoom siv hluav taws xob ntawm Qib B thiab yog tsim los siv hluav taws xob-Cov txheej txheem vuam -9.
Q5: Rau tus nqi -rhiab heev, qis- cov kab dej siab, qib twg thiab hom twg feem ntau pom zoo?
A:Rau cov ntawv thov zoo li no, A53 Gr.A, Hom F (Lub Rauv-Butt Welded) yeeb nkab feem ntau pom zoo vim nws qhov txiaj ntsig kev lag luam.
