Cov Lus Qhia Tseem Ceeb
1. A513 tsis yog rau siab
Nov yog qhov tseem ceeb tshaj qhov txawv:ASTM A513 yog txhua yam tubing, tsis siab yeeb nkab. Yog tias koj xav tau cov kua dej hauv qab, qhia meejASTM A53los yogASTM A106 1hloov.
2. Cov khoom nyob ntawm qib xaj
Tsis zoo li A500 lossis A53 uas muaj qhov yuav tsum tau ua tiav qib, A513 cov khoom sib txawv raws li qib steel koj teev (1008 vs. 1026 vs. 4130) thiab cov txheej txheem ua haujlwm .
3. Hom 2 vs. Hom 1 Xaiv
Hom 1 (Kub-Rolled):Kev lag luam, qhov loj dua, tsawg dua qhov tseem ceeb
Hom 2 (Cold-Rolled):Precision daim ntaub ntawv, zoo dua nto, nruj tolerances
4. DOM (Hom 5) rau cov ntawv thov tseem ceeb
Rau cov ntawv thov uas xav tau:
Smooth sab hauv
Yam tsawg kawg nkaus tolerances
Siab zog
Tsis muaj internal weld hlaws
QhiaDOM (Drawn Over Mandrel)tubing, uas yog A513 Hom 5 .
Thaum kawg Takeaway: ASTM A513 ERW Yeeb Nkabyog covntau yam mechanical tubing standardrau cov uas tsis yog - cov ntawv siv siab xav tau lub zog zoo, tsim tau, thiab qhov zoo. Muaj nyob rau hauv ntau hom carbon thiab alloy steel qib (1008 txog 4130), nws ua haujlwm rau kev lag luam los ntawm tsheb thiab rooj tog rau kev siv tshuab. Rau kev siv siab, txawm li cas los xij, nws yogtsis haum– uas yuav tsum tauASTM A53 lossis A106.
