A672 longitudinal welded yeeb nkab yog siab - steel yeeb nkab ua tau zoo siv dav hauv kev lag luam xws li roj av, roj av, tshuaj, thiab hluav taws xob.
A672 Cov khoom siv yeeb nkab sib npaug
ASTM A672 yog ib qho hluav taws xob-Fusion-Welded (EFW) yeeb nkab spec rau siab- kev pabcuam siab, nrog cov qib (xws li B60, B70, C65) sib raug rau cov khoom siv hauv qab siab lub nkoj phaj, feem ntau ASTM A516 Qib (xws li, B60} zoo li {1116}, C70 zoo li A516 Gr. 70), EN sib npaug (xws li P265GH, P355GH), thiab cov qauv BS qub (BS 1501), qhia lub zog thiab muaj pes tsawg leeg.

Qhov txawv ntawm A106 thiab A672 yog dab tsi?
| Feature | A106 steel yeeb nkab | A672 steel yeeb nkab |
|---|---|---|
| Txuj | ASTM A106 1 | ASTM A672 Cov Lus Qhia Tshwj Xeeb |
| Hom | Seamless carbon steel yeeb nkab rau siab -kev pabcuam kub | Hluav taws xob-fusion-welded steel yeeb nkab rau atmospheric thiab qis kub kev pab cuam |
| Kev siv thawj zaug | High -kub siv xws li fais fab nroj tsuag, refineries, thiab petrochemical nroj tsuag | Kev thauj mus los hauv cov roj av, tshuaj lom neeg, hluav taws xob, thiab lwm yam kev lag luam nyob rau hauv atmospheric thiab qis kub |
| Khoom siv | High - carbon steel zoo | Cov pa roj carbon-manganese steel nrog rau qhov muaj peev xwm ntxiv ntawm lwm cov ntsiab lus xws li vanadium rau kev txhim kho cov khoom |
| Qhov kub thiab txias | Haum rau siab - qhov kub thiab txias | Haum rau kev khiav hauj lwm ib puag ncig feem ntau xws li ntawm -20℃mus rau 300 degree |
| Kev tsim khoom | Seamless (kub- dov los yog txias-kos) | Hluav taws xob fusion vuam |
| Lub zog | Lub zog siab ntawm qhov kub siab | Lub zog zoo thiab siab ua haujlwm nyob rau hauv nws qhov ntsuas kub qhov ntsuas |
| Daim ntawv thov | Boilers, superheaters, heat exchangers, thiab lwm yam siab -kub tshuab | Kev thauj mus los dav dav, suav nrog dej, roj, thiab roj, hauv ntau qhov chaw tsim khoom |
