astm a671 vs a106 ua
| Feature | ASTM A671 Cov Lus Qhia Tshwj Xeeb | ASTM A106 1 |
|---|---|---|
| Txhais | Qhia meej txog qhov yuav tsum tau ua rau hluav taws xob- fusion-welded steel kav npaj rau atmospheric thiab qis dua - qhov kub thiab txias, nrog rau siab - cov ntawv thov siab (tshwj xeeb yog qhov yuav tsum muaj qhov tsis zoo ntawm qhov kub thiab txias). | Npog seamless carbon steel yeeb nkab rau siab - kev pabcuam kub (feem ntau yog siv rau hauv cov kav dej saum toj -29℃(-20℃F) thiab mus txog qhov ntsuas kub nyob ntawm qib). |
| Kev tsim khoom | Electric Fusion Vuam (EFW) | Seamless (kub- dov los yog txias- kos / tiav) |
| Kev siv thawj zaug | Atmospheric thiab qis dua -kev pabcuam kub; siab - cov ntawv thov siab yuav tsum tau ua kom tawv nqaij ntawm qhov kub thiab txias. | High -kev pabcuam kub hauv kev lag luam xws li roj av refineries, tshuaj nroj tsuag, tsim hluav taws xob, thiab lwm yam. |
| Hom khoom | Feem ntau suav nrog carbon thiab qis- alloy steels. | Carbon steel nkaus xwb (Qib A, B, C). |
| Qhov Loj | Feem ntau qhov loj dua, feem ntau siv rau cov kav dej loj dua. | Ntau qhov ntau thiab tsawg, tab sis feem ntau me dua A671 nyob rau hauv ntau daim ntawv thov vim seamless manufacturing txwv. |
| Qhov kub thiab txias | Tsim los rau kev pabcuam kub qis nrog cov khoom zoo toughness. | Tsim los rau siab - qhov kub thiab txias kev pab, nrog rau qhov ntsuas kub siab tshaj plaws raws li qib. |
| Kev xeem yuav tsum tau | suav nrog cov kev cai tshwj xeeb rau kev ntsuas qhov tawv tawv (piv txwv li, Charpy V-qhov ntsuas qhov cuam tshuam) ntawm qhov kub thiab txias. | Kev ntsuam xyuas tsom mus rau lub zog tensile, tawm lub zog, elongation, thiab hardness ntawm chav tsev kub thiab siab kub. |
| Daim ntawv thov | Siv nyob rau hauv cov kav dej, cov hlab ntsha siab, thiab kev siv cov txheej txheem uas tsawg - qhov kub thiab txias yog qhov tseem ceeb. | Dav siv nyob rau hauv siab - kub thiab siab - cov kav dej siab hauv cov tshuab ua kom zoo, cov chaw tsim hluav taws xob, thiab lwm qhov chaw tsim khoom. |
