1. Cov Khoom Siv Khoom Tseem Ceeb
| Chaw ua uas tsis tau haus | P265Ghgh Specifications |
|---|---|
| Daim Ntawv Qhia Txog Tus Hlau Hlau | Cov nplej puab uas tsis yog-alloy hlau rau kev pabcuam kub ("P" sawv ntsug rau lub nkoj siab) |
| Paib lub zog | Ntau dua los yog sib npaug rau 265 MPa |
| Lis Tswjhwm | Ntxiv cov nqi nyiaj ntawm NB / V / TI mus rau refine nplej ("g" logo) |
| Kev ua haujlwm kub siab | Tsim Kev Pab Kub tsawg dua lossis sib npaug nrog 400℃("H" cim) |
| Carbon sib npaug CEQ | Tsawg dua los yog sib npaug rau 0.36% (optimized weldability) |
2. Qhov sib txawv tseem ceeb los ntawm cov kav dej seamless
| Nta | EN10217-2 | EN10216-2 |
|---|---|---|
| Kev ua | Lsaw lossis ERW | Kub Rolled / Txias Dreen seamless |
| Kev kuaj xyuas | WELD tsis yog kev ua phem rau (xws li ultrasonic) yuav tsum muaj | Tsom ntsoov rau tag nrho qhov tsis pom kev thiab ntsuas dej siab |
| Cov Ntawv Thov | Anti-corrosion kav (xws li 3LPE sab nraud tiv thaiv corrosion) | Kev Kub Siab Kub Siab Ntshav / Boiler Qhov Chaw |
| Daim Ntawv | Rolled Steel Phaj Vuam | Direct Kub Rolling |
3. Tshuaj lom neeg sib xyaw ua ke thiab kev ua haujlwm
Kev sib xyaw ua ke (ib txwm muaj welded kav thiab seamless kav):
C Tsawg dua los yog sib npaug rau 0.20%, MN: 0.50-1.40%, p tsawg dua lossis sib npaug lossis ntau dua lossis sib npaug 0.01%
Lw Alloys: NB / V / TI tsawg dua lossis sib npaug rau 0.05% (ua kom zoo nplej)
Tus me nyuam xwm txheej:
Welded Yeeb: Lub Cheeb Tsam Weld xav tau kev kho mob li qub (ntxhov siab heev)
Seamless yeeb nkab: xa tawm hauv lub xeev tag nrho
️
4. Kev xaiv txiav txim siab
Cov kev txwv ntawm welded kav dej: Seamless Yeeb Nkab P265GH yog nyiam rau qhov kub thiab kub siab tshaj (li cov kabmob kub siab-;
Muaj feem cuam tshuam rau welded kav dej: thaum nruab nrab thiab kub raws li 350 degree) thiab sab nraud ntawm LSAW cov txheej txheem tuaj yeem xaiv;
American txheem sib piv: Lub seamless yeeb daim ntawv tuaj yeem sib npaug rau ASTM A106 Gr.B / Astm A53 Gr.3 Gr.B, tab sis tsis muaj tus qauv coj ncaj qha rau welded kav dej.
