1. Lub npe tag nrho rau A53 Gr B yeeb nkab yog dab tsi?
Teb:Cov lus qhia tag nrho yog ASTM A53 Qib B. "ASTM" yog hais txog lub koom haum qauv (American Society for Testing and Materials), uas txhais cov kev cai rau cov khoom siv no.
2. Ob lub ntsiab ntawm A53 Qib B yeeb nkab yog dab tsi, thiab lawv txawv li cas?
Teb:Ob hom tseem ceeb yog Hom E (Electric Resistance Welded) thiab Hom S (Seamless).
Hom E:Nws muaj ib tug welded seam raws nws ntev. Nws feem ntau yog kev lag luam ntau dua.
Hom S:Tsis muaj seam, ua rau nws muaj zog thiab sib xws hauv nws lub siab - muaj peev xwm. Nws yog siv rau cov ntawv thov tseem ceeb dua.
3. Daim ntawv thov feem ntau yog dab tsi rau A53 Qib B yeeb nkab?
Teb:Nws daim ntawv thov feem ntau yog rau qis - cov kav dej siab, tshuab tshuab, thiab kev siv cov qauv. Nws yog dav siv rau conveying cua, dej, chav, thiab roj. Nws kuj yog feem ntau siv los ua cov txheej txheem scaffolding.
4. Dab tsi yog cov khoom tseem ceeb ntawm A53 Qib B steel?
Teb:
Yam tsawg kawg Tensile Strength: 415 MPa (60,000 psi)
Yam tsawg kawg yield zog: 240 MPa (35,000 psi)
Cov khoom no ua rau nws muaj zog thiab ductile txaus rau ntau yam kev ua haujlwm siab thiab kev ua haujlwm.
5. A53 Qib B txawv li cas ntawm A500 Qib B structural tubing ntau dua?
Teb:Thaum ob leeg muaj "Qib B," lawv tau tswj hwm los ntawm cov qauv ASTM sib txawv rau cov hom phiaj sib txawv.
A53 Gr B: Kavcev, siv feem ntau rau siab conveyance. Nws tau teev tseg los ntawm Nominal Pipe Size (NPS) thiab lub sijhawm (phab ntsa thickness).
A500 Gr IB:Tswjstructural tubing, siv rau load-cov tswv cuab. Nws tau teev los ntawm qhov ntev sab nraud (piv txwv li, 2 "x 2") thiab phab ntsa thickness. Lawv cov khoom siv kho tshuab thiab cov kev xeem yuav tsum sib txawv.
