1. ASTM A500 yog dab tsi?
ASTM A500 yog tus qauv specification luam tawm los ntawm ASTM International rau txias - ua welded thiab seamless carbon steel structural tubing ua nyob rau hauv round, square, rectangular, thiab tshwj xeeb duab-2. Nws yog qhov tshwj xeeb tshaj plaws rau Hollow Structural Sections (HSS) siv hauv kev tsim kho hauv Tebchaws Meskas-2-5.
2. Dab tsi yog cov ntawv thov rau A500 tubing?
Cov tubing no yog tsim los rau welded, riveted, los yog bolted kev tsim kho ntawm cov choj thiab cov tsev, thiab rau cov hom phiaj dav dav-1-3-7. Cov ntawv thov feem ntau suav nrog kev tsim cov ncej, txuas hniav, cov yees, thiab ntau yam kev txhawb nqa-5.
3. Dab tsi yog qhov loj thiab thickness txwv rau A500 tubing?
Cov kev qhia tshwj xeeb npog cov raj nrog qhov siab tshaj plaws periphery (tag nrho cov cheeb tsam sab nraud) ntawm 88 ntiv tes [2235 mm] thiab qhov siab tshaj plaws phab ntsa thickness ntawm 1.000 nti [25.4 hli] raws li qhov tseeb 2023 version-3. Cov ntawv qub, zoo li 2018 tsab, teev qhov siab tshaj plaws ntawm 0.875 hauv. [22 hli]-1-8. Hauv tsev, square HSS muaj txog li 22x22 ntiv tes, duab plaub txog 34 ntiv tes, thiab puag ncig mus txog 28 ntiv hauv txoj kab uas hla-5.
4. A500 tubing ua li cas?
Nws yog tsim los ntawm kev ua kom txias -. Cov tubing tuaj yeem yog seamless lossis welded. Welded tubing yog tsim los ntawm tiaj tus- dov steel siv hluav taws xob-kuj- vuam (ERW) txheej txheem, qhov twg cov npoo yog rhuab thiab forged ua ke-5-7.
5. Cov khoom siv hauv qab A500 yog dab tsi, thiab qhov twg feem ntau?
ASTM A500 txhais tau ntau qib ntawm cov pa roj carbon steel raws feem ntau ntawm cov khoom siv zog-2. Qib C, nrog qhov tsawg kawg nkaus lub zog ntawm 50 ksi thiab tensile lub zog ntawm 62 ksi, yog cov khoom tseem ceeb muaj rau txhua daim duab-5. Feem ntau hauv tsev tsim HSS yog dual-certified rau Qib B thiab C, yog li Qib C raug pom zoo raws li lub neej ntawd rau qhov project specifications-5.
