1. ASTM A671 CJB115 Class 10 steel yeeb nkab yog dab tsi?
Teb:
ASTM A671 CJB115 Chav Kawm 10 yog ib qhohluav taws xob-fusion-welded (EFW) carbon steel yeeb nkabtsim rauqis- mus rau- kev pabcuam kub nruab nrab(feem ntau tshaj -20℃F / -29℃). Lub npe "Class 10" qhia tias aYam tsawg kawg nkaus tawm lub zog ntawm 10 ksi (69 MPa), ua rau nws tsim nyog rau kev siv dav dav - lub hom phiaj kev lag luam nrog kev xav tau qis dua.
2. Dab tsi yog cov ntsiab lus tseem ceeb?
Teb:
Khoom Qib:CJB115 carbon steel (sib txawv chemistry los ntawm CJA115)
Yield zog:Ntau dua lossis sib npaug rau 10 ksi (69 MPa)
Tensile zog:48-67 ksi (331-462 MPa)
Impact Test:Tsis tas yuav tsum muaj rau Chav Kawm 10
Tshuaj muaj pes tsawg leeg:Cov ntsiab lus carbon ntau dua li qib CJA (C Tsawg dua lossis sib npaug rau 0.35%, Mn Tsawg dua lossis sib npaug rau 1.35%)
3. Nws feem ntau siv qhov twg?
Teb:
Feem ntau rau:
Tsawg-kev thauj cov kua siab (dej, roj)
Kev siv cov qauv hauv qhov chaw me me
Tsis yog - tseem ceeb rau kev lag luam piping systems
4. Nws piv rau cov chav kawm siab dua li cas?
Teb:
| Chav kawm | Yield zog | Kev siv yam |
|---|---|---|
| 10 | 10 ksg | Tsawg-siab dav siv |
| 55 | 5 5 ksg | Siab siab |
| 70+ | 70+ tsi | Siab -siab/cryogenic |
5. Fabrication xav tau?
Teb:
Vuam:Cov txheej txheem txheem (tsis muaj preheat feem ntau xav tau)
Kev sim:Basic hydrostatic xeem
Kev tsim:Txias khoov tso cai tsis muaj kev ntxhov siab
