1. Q: Dab tsi yog qhov tseem ceeb ntawm ASTM A500?
A:ASTM A500 yog tus qauv qhia tshwj xeeb rau txias- ua welded thiab seamless carbon steel structural tubing nyob rau hauv round, square, thiab rectangular duab. Nws yog feem ntau yog siv rau welded, riveted, los yog bolted kev tsim kho ntawm cov choj thiab cov tsev, thiab rau cov hom phiaj dav dav.
2. Q: Qhov txawv ntawm ASTM A500 thiab A501 yog dab tsi?
A:ASTM A501 yog rau kub- ua welded thiab seamless carbon steel structural tubing. Qhov sib txawv tseem ceeb yog qhov kub thiab txias. Txawm li cas los xij, nws tseem ceeb heev uas yuav tsum nco ntsoov tias ASTM A501 tau raug tshem tawm ntau thiab hloov los ntawm ASTM A500. Rau feem ntau cov haujlwm tshiab, A500 yog tus qauv teev tseg.
3. Q: Cov qhab nia (hom) hauv ASTM A500 yog dab tsi, thiab lawv txawv li cas?
A:ASTM A500 muaj ntau qib raws li tus ntoo khaub lig-sectional shape:
Qib A:Round, Square, thiab Rectangular tubing.
Qib B:Round, Square, thiab Rectangular tubing.
Qib C:Round, Square, thiab Rectangular tubing.
Qib D:Square thiab Rectangular tubing nkaus xwb.
Qhov sib txawv ntawm lawv yog qhov tsawg kawg nkaus lub zog thiab lub zog tensile, nrog Qib B thiab Qib C feem ntau muab lub zog siab dua qib A.
4. Q: Dab tsi yog qhov tsawg kawg nkaus tawm los thiab tensile lub zog yuav tsum tau rau Qib B, Round Tube?
A:Rau Qib B puag ncig lub raj, qhov tsawg kawg nkaus tawm lub zog yog 42 ksi (290 MPa), thiab lub zog tensile yam tsawg kawg nkaus yog 58 ksi (400 MPa).
5. Q: Puas yog ASTM A500 npog ob leeg welded thiab seamless tubing?
A:Yog lawm, ASTM A500 npog ob qho tib si txias- ua welded (hluav taws xob-kuj welded) thiab seamless carbon steel tubing. Cov txheej txheem yuav tsum siv rau ob qho tib si, txawm tias lawv cov txheej txheem tsim khoom sib txawv.
