Nyob rau hauv lub teb twg lossis kev lag luam yog e 307-26 dav siv?

Nyob rau hauv daim teb ntawm kev muaj vuam cov ntaub ntawv, e {307-26}}}}} pding cov pas nrig tau dhau los ua ntau yam kev lag luam vim lawv cov khoom tshwj xeeb. Kab lus no qhia nws cov chaw thov tseem ceeb los ntawm kev txheeb xyuas nws cov khoom siv, cov ntaub ntawv thov thiab cov ntaub ntawv muab khoom lag luam thiab cov ntaub ntawv luam tawm.

Cov yam ntxwv tseem ceeb ntawm e 307-26} vuam rods

E 307-26 yog lub siab-alloy-alloy steel hlau vuam rod tsim los sib txuas thiab ua kom muaj peev xwm sib xws. Raws li cov qauv thoob ntiaj teb (xws li AWS / ASME SFA {2}}, 8% thiab kev ua haujlwm siab tshaj plaws ntawm kev sib cais ntawm cov pob qij txha tsis ruaj khov yog 300 degree. Ib qho ntxiv, nws cov 160% kev ua tau zoo ua rau nws xaiv qhov zoo tshaj plaws rau cladding thiab ceev vuam scararios.

1. Fais Fab Kev Lag Luam: Txij Nkawm thiab Kev Tsim Cov Khoom Siv Fais Fab Nroj Tsuag

• Cov pov thawj tseem ceeb qhia tau hais tias e 307-26 vuam rods yog feem ntau siv nyob rau hauv lub zog kev lag luam, tshwj xeeb tshaj yog nyob rau hauv lub zog kev lag luam, tshwj xeeb tshaj yog nyob rau hauv cov khoom siv tseem ceeb hauv cov khoom siv hluav taws xob. Piv txwv li: MetMax 307R Stainless Hlau Vuam Rod E {2}}}}} ntawm cov nroj tsuag hluav taws xob tsuas yog ua cov kav dej kub xws li cov kav dej kub thiab cov khoom siv boiler thiab cov khoom siv turbine.
• Cov Khoom Siv Hluav Taws Xob Cov Khoom Siv Ntau Tshaj Plaws xav tau kev khiav lag luam hauv qab kub thiab chromium-molybdenum steel hlau vuam) muaj peev xwm ua kom tau txais lub neej ntawm cov khoom siv.

2. PETROCHEMICAL thiab lub zog: qhov kub thiab txias thiab thaj chaw corrosive

Hauv cov liaj teb ntawm Petrochemicals, Roj Refining thiab ntuj nkev, e 307-26 yog siv rau:

• Kev nthuav dav hlau sib txuas: xws li vuam carbon hlau thiab stainless hlau los daws cov teeb meem kev ntxhov siab tshwm sim los ntawm cov khoom nthuav dav coefficients.
• Overlaying orrosion txheej: overlaying corrosion-resistant txheej los txhim kho lub peev xwm ntawm hydrogen sulfide thiab acidic xov xwm corrosion.

3. Kev tsim tawm dav dav: Kev siv tau yooj ywm nyob rau hauv cov kev ua haujlwm tshwj xeeb txawm hais tias nws tsis yog cov xwm txheej hauv qab no: cam khwb cia hlau kho:

• Piv txwv li, hauv Reptec series ntawm Lincoln Vuam cov ntaub ntawv, e 307-26 yog siv rau kev siv hlau me me cam khwb cia hlau chaw, suav rau hauv tus account ua kev ua haujlwm.
• Khoom noj khoom haus thiab cov khoom noj khoom haus: vim yog cov khoom noj khoom haus huv ntawm cov hlau tsis xeb, nws yog siv rau weld kav dej thiab cov nkoj tawm tsam.

Los ntawm cov khoom siv hluav taws xob hauv ntiaj teb, cov xa khoom tseem ceeb ntawm e 307-26 Cov quashter (MetMolax Nws cov kev thov kev loj hlob yog cuam tshuam nrog cov ncauj lus nram qab no:

• Lub zog hluav taws xob cog hloov kho dua tshiab thiab kev hloov pauv: nrog kev hloov ntawm cov khoom siv hluav taws xob qub, qhov kev thov rau cov khoom kub uas tiv taus ntau ntxiv.
• Kev loj hlob huv: Cov cai kom muaj rau cov khoom siv roj av rau cov roj av ua rau roj av tau txhawb nqa daim ntawv thov ntawm e 307-26. Cov qauv thoob ntiaj teb tau ua stricter: ISO, AWS thiab lwm cov qauv muaj cov tuam txhab vuam zoo, ua cov tuam txhab kom txaus los xaiv cov ntaub ntawv muaj ntawv pov thawj xws li e {2}}.

Kev ua ke ntawm cov ntaub ntawv ua haujlwm thiab cov lag luam lag luam, cov chaw siv vuam ntau tshaj plaws, tshwj xeeb yog kev saib xyuas muaj ntau lub zog, tshwj xeeb yog kev saib xyuas ntawm cov khoom kub siab thiab cov khoom siv siab hauv cov khoom siv hluav taws xob. Thib ob, nws cov kev xav tau rau vuam disimilility cov hlau nyob rau hauv cov kev kub-kub corrosive ib puag ncig xws li petrochemicals thiab lub zog txuas ntxiv loj hlob. Nyob rau hauv lub neej yav tom ntej, nrog kev txhim kho cov cuab yeej siv thiab kev txhim kho cov ntaub ntawv tshiab, tab sis nws txoj haujlwm tseem ceeb hauv lub hwj chim yuav nyuaj los hloov lub sijhawm luv luv.
