1. ASTM A671 CJB115 Class 11 steel yeeb nkab yog dab tsi?
Teb:
ASTM A671 CJB115 Chav Kawm 11 yog ib qhohluav taws xob-fusion-welded (EFW) carbon steel yeeb nkabtsim raulow-siab thiab nruab nrab-kev pabcuam kub(feem ntau tshaj -20℃F / -29℃). Lub npe "Class 11" qhia tias aYam tsawg kawg nkaus lub zog ntawm 11 ksi (76 MPa), ua rau nws tsim nyog rau kev lag luam kev siv nrog me ntsis siab dua li Chav Kawm 10.
2. Cov ntsiab lus tseem ceeb thiab cov khoom siv?
Teb:
Khoom Qib:CJB115 carbon steel (siab dua carbon dua CJA qib)
Yield zog:Ntau dua lossis sib npaug rau 11 ksi (76 MPa)
Tensile zog:50-70 ksi (345-483 MPa)
Impact Test:Tsis tas yuav tsum muaj rau cov ntawv thov txheem
Tshuaj muaj pes tsawg leeg:C Tsawg dua lossis sib npaug li 0.35%, Mn Tsawg dua lossis sib npaug li 1.35%, P / S Tsawg dua lossis sib npaug li 0.035%
3. Cov ntawv thov zoo li cas?
Teb:
Tsawg-kev thauj cov kua siab (dej, roj, roj)
Cov khoom tsim nyob rau hauv ib puag ncig me me
Industrial piping systems nrog rau nruab nrab lub zog xav tau
4. Nws piv rau lwm cov chav kawm CJB115 li cas?
Teb:
| Chav kawm | Yield zog | Kev ntsuas siab |
|---|---|---|
| 10 | 10 ksg | Basic low -siab |
| 11 | 11 ksg | Txhim kho qis - siab |
| 15 | 15 ksg | Nruab nrab -siab |
5. Fabrication thiab vuam yuav tsum tau?
Teb:
Vuam:Cov txheej txheem txheem (preheat yeem rau cov ntu tuab)
Kev sim:Hydrostatic kuaj ntawm 1.5x tsim siab
Kev tsim:Txias bending tso cai rau feem ntau daim ntawv thov
