P355nl1 p355nl2 boiler phaj
P355Nl1 Steel Steel yog European txheem siab txog ntsha Hlau Steel Phaj, ua raws li European Standic EN10028. Lub phaj steel yog ua los ntawm converter steelmaking los yog hluav taws xob rauv tsis zoo cov nplej loj hlau. P355Nl1 lub nkoj muaj zog pho tau qaug zog, tsis tshua muaj cua tsis kam, muaj txiaj ntsig zoo, lub zog thiab tawv.
P355Nl2 yog European cov qauv Cryogenic thawv phaj. P355nl2 yog European txheem thawv phaj. Tus P355Nl2 Hlwb Hlau Hlau Qib Qib Qib "Qhia tias cov hlau yog tshwj xeeb qis {}} kub siab- zoo steel. P355NL2 boiler steel phaj muaj cov xwm txheej zoo thiab kev ua haujlwm vuam. Lawv cov kev siv dav dav ntau tshaj plaws yog nyob rau hauv cov ntawv thov hauv qab -20 degree.
P355nl1 vs p355nl2 Xav paub ntau ntxiv
P355nl2
Kev nplua cov txheej txheem sib dhos rau cov hlab ntsha siab. P355NL2 hlau yog tus cwj pwm los ntawm kev tsim txiaj zoo thiab muaj kev tiv thaiv siab rau nkig tawg. Cov hom no yog siv rau saum toj no tag nrho rau cov nkoj tsim khoom rau cov roj txheem nias (LPG, cov khoom lag luam siab, thiab lwm yam. Lawv cov khoom siv siab tshaj plaws yog hauv cov ntawv thov qis dua -20º.
P355nl2 steel yog muab rau hauv qhov xwm txheej qub. Kev ntsuas kub ib txwm yog {{3} ºC, thiab nws yuav tsum tau sab laug hauv lub cub tawg tom qab kub ntawm lub phaj tuab ntawm cov phaj tuab ntawm phaj. Raws li qhov tshwm sim, nws muaj cov khaub thuas zoo - kev sib sau thiab kub} Txoj kev ua tau cuam tshuam cov khoom siv tau tsis zoo.
Cov khoom lag luam zoo sib xws hauv cov hlau hauv cov koob no tuaj yeem zoo kawg nkaus, ob leeg thiab siv cov khoom siv vuam ua haujlwm.
P355nl1
Kev nplua cov txheej txheem sib dhos rau cov hlab ntsha siab. P355Nl1 steel yog tus cwj pwm los ntawm kev tsim txiaj zoo thiab cov siab tiv taus rau nkig tawg. Cov hom no yog siv rau saum toj no tag nrho rau cov nkoj tsim khoom rau cov roj txheem nias (LPG, cov khoom lag luam siab, thiab lwm yam. Lawv cov khoom siv siab tshaj plaws yog hauv cov ntawv thov qis dua -20º.
P355Nl1 steel yog muab rau hauv qhov xwm txheej no. Kev ntsuas kub ib txwm yog {{3} ºC, thiab nws yuav tsum tau sab laug hauv lub cub tawg tom qab kub ntawm lub phaj tuab ntawm cov phaj tuab ntawm phaj. Raws li qhov tshwm sim, nws muaj cov khaub thuas zoo - kev sib sau thiab kub} Txoj kev ua tau cuam tshuam cov khoom siv tau tsis zoo.
Cov khoom lag luam zoo sib xws hauv cov hlau hauv cov koob no tuaj yeem zoo kawg nkaus, ob leeg thiab siv cov khoom siv vuam ua haujlwm.
P355nl1, p355nl2, p355NH, p355GH, 1.0565, 1.0566, 1.0473 - Cov hlau me me
P355 Qib Pib Qibyog cov khoom lag luam zoo ntawm cov khoom siv nrog cov khoom siv neeg kho kom zoo.
P355 steelyog me, zoo grain qauv qauv steel uas feem ntau siv nyob rau hauv cov hlab siab thiab boilers. Nws lub zog siab thiab corrosion tsis kam ua rau nws txoj kev xaiv zoo tshaj plaws rau kev siv hauv kev siv cov kev siv tau.
Subgrades ntawm P355 Qib Qib
P355 Qib qib steel muab faib ua ob peb cov kev sib cais uas txawv hauv lawv cov khoom tshwj xeeb:
P355ghugh: Cov hlau no yog tsim los rau high- sov daim ntawv thov thiab yog tus cwj pwm kub thiab yog tus cwj pwm los ntawm lub zog siab ntawm qhov kub ntawm xyoo 8000 degree.
P355nh: Cov hlau no yog tsim los rau qis - sov daim ntawv thov thiab yog tus cwj pwm kub thiab yog tus cwj pwm los ntawm kev kub siab ntawm qhov kub tsawg.
P355nl1thiab p355nl2: cov steel sib faib yog tsim rau cov ntawv thov uas muaj kev nruj ntawm qis (P355nl1), tsawg heev (P355nl2) Qhov kub thiab muaj weldability zoo yuav tsum tau.
Nyob rau hauv cov nqe lus ntawm cov neeg kho tshuab, yog lub zog tensile, tab sis tus nqi ntawm cov txiaj ntsig sib txawv ntawm lawv (nws yog me ntsis rauP355nh). Qhov sib txawv no cuam tshuam rau lub peev xwm thauj khoom ntawm tus neeg alloys alloys muaj rau qib no thiab yog li qhov tau txais ntawm lawv siv.
