P355 hlauntau yam yog cov qib siab ntawm cov hlab ntsha steel nrog zoo weldability thiab siab tsis kam mus nkig cracking, P355NH yog siv los ntawm lub ntiaj teb no fabricators rau kev tsim cov hlab ntsha siab tso tsheb hlau luam rau khaws cia ntawm cov pa roj.
Nomenclature Breakdown ntawm P355 Boiler Phaj Qib
- P- Kev siv cov cuab yeej siv siab
- 355- Yam tsawg kawg nkaus kev ntxhov siab (MPa) rau t Tsawg dua lossis sib npaug li 16 hli
- N-Normalized shipping (los yog normalized dov)
- H- Tus qauv nce siab- qhov kub thiab txias, cuam tshuam kuaj ntawm -20 degree
- L1- Tsawg-kub toughness, cuam tshuam kuaj ntawm -40 degree
- L2- Txhim kho qis-kub toughness, cuam tshuam kuaj ntawm -50 degree
Kev nkag siab txog cov lus xaus no pab cov kws tsim qauv tsim kom haum rau txoj cai P355NH, NL1, lossis NL2 steel rau lub nkoj qhov ntsuas kub thiab cov cai.
Qhov txawv ntawm P355NH, P355NL1, thiab P355NL2
Thaum lawv cov tshuaj lom neeg muaj pes tsawg leeg yog qhov tseem ceeb zoo ib yam thiab txhais los ntawm tib yam kev ntsuas cua sov txwv, qhov sib txawv tseem ceeb nyob rau hauv kev lees paub lub zog ntawm qhov kub thiab txias. Tag nrho peb yuav tsum ua tiav 27 J yam tsawg kawg nkaus ntawm qhov ntev ntawm Charpy V-notch specimens, tab sis ntawm qhov ntsuas kub sib txawv. Qhov no cuam tshuam ncaj qha rau kev xaiv cov khoom siv: P355NH haum rau cov qauv boiler plhaub, P355NL1 haum rau cov tub yees txias txias, thiab P355NL2 ua tau raws li qhov xav tau ntawm cov khoom siv cryogenic cia mus txog -50 degree. GNEE khaws cov khoom sib cais rau txhua qib kom khaws tag nrho traceability thiab ntawv pov thawj.
