1. General Tsis-Alloy Steel Welded Kav
Tub Ntxhais Asmeskas: Astm A53 (Seamless thiab Welded Steel Kav)
Khoom Siv Khoom:
| EN10217-1 Khoom | ASTM A53 Khoom |
|---|---|
| P235tr1 / TR2 | GR.B3 |
| P265tr1 / TR2 | Gr.B |
Daim Ntawv Thov Kev Ua Si: Kev Txhawb Nqa Lub Tsev, Kev Siv Dej Qev Khoom Siv Nyiaj Siv Dej / Roj)
Cov Txheej Txheem Yuav Tsum Tau: Ob leeg yuav tsum tau ua kom tau ntsuas dej siab thiab cov qauv kuaj tsis yog kev ua phem rau
2. Kev tsav tsheb qis rau kev thauj khoom qis
Asmeskas Cov Qauv Xaiv: ASTM A135 (Kuj Welded Steel Yeeb Nkab)
Ntais ntawv cov kav dej thiab HVAC kav hauv EN10217-1 (xws li P235TR2 qib)
Phab Ntsa Thickness ntau ntau: tau tshaj nrog European Standement S275 Qeb Welded Yeeb Nkab
️
3. Kev txwv tshwj xeeb
Siab qib txawv:
EN10217-1 siv tau los tsim kev tsim qauv siab dua lossis sib npaug ntawm 16bar, thaum Astm A53 / A13 / A-B (sib npaug rau 20bar)
Daim Ntawv Sau:
EN10217-1 feem ntau yog puag ncig hlab, thiab Asmeskas cov qauv ASTM A53 kev txhawb nqa ob qho tib si rhawv hlua thiab square hlab
Kev siv kub siab:
Both are not applicable to working conditions of>350℃(Astm A106 lossis EN10217-4)
Xaiv cov lus pom zoo: Astm A53 Gr.B (lub zog phim P265TR1) yog nyiam rau kev teeb tsa tsev; ASTM A1355, uas muaj txiaj ntsig zoo dua, tuaj yeem xaiv tau rau cov ntshav hauv cov ntshav ntshiab. Thaum nws los txog rau kev ua kom muaj ib puag ncig uas muaj kev tiv thaiv ib puag ncig, kev tiv thaiv kev tiv thaiv corrosion yog yuav tsum tau ua. Gnee pab pawg muab cov txheej txheem los tiv thaiv kev ua kom haum.
