ASTM A515 gr 70 phaj: zoo tagnrho xaiv rau boilers thiab tso tsheb hlau luam

GNEE Steel yog pioneer tsum ntawmASTM A515 Gr 70 Carbon Steel Sheets thiab Phajhauv Suav teb. Peb tsim cov ASTM A515 Qib 70 CS Cov Ntawv thiab Phaj hauv peb lub xeev ntawm cov chaw tsim khoom. Peb siv cov tshuab niaj hnub rau kev tsim cov nplooj ntawv thiab daim hlau uas ua kom cov khoom zoo tshaj plaws thiab txhim khu kev qha. Peb cov neeg ua haujlwm raug cob qhia ua ntau yam kev kuaj xyuas zoo ntawm cov khoom siv raw kom paub tseeb tias nws tsis muaj qhov tsis xws luag. Txhua txheej txheem los ntawm kev tsim khoom mus rau kev xa khoom yog ua raws li peb lub zeem muag ntawm peb cov neeg ua haujlwm tshaj lij kom paub tseeb tias txhua qhov kev ntsuas xav tau raug coj mus rau hauv tus account.

ASTM A515 Gr 70 phaj yog cov pa roj carbon - silicon steel phaj uas feem ntau yog siv rau siab - qhov kub thiab txias kev pab cuam hauv boilers thiab siab hlab ntsha. Qib ntawm cov hlau no muaj qhov zoo tshaj plaws weldability thiab haum rau nruab nrab thiab qis kub kev pab cuam.

Ib qho ntawm qhov zoo tshaj plaws ntawmASTM A515 Gr70yog nws lub zog tensile siab, uas tso cai rau nws tiv taus kev kub ntxhov thiab kev ntxhov siab. Cov khoom siv kuj muaj kev tiv thaiv corrosion zoo thiab tiv taus oxidation thiab sulfidation ntawm qhov kub thiab txias.

Lwm qhov kom zoo dua ntawm ASTM A515 Gr 70 phaj yog nws tus nqi qis dua piv rau lwm cov khoom siv kub siab, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau tus nqi - cov ntawv thov rhiab heev.

Txawm li cas los xij, nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias ASTM A515 Gr 70 steel tsis pom zoo siv rau hauv qhov chaw ua haujlwm qaub vim nws raug rau hydrogen -induced cracking (HIC). Nws kuj tsis haum rau cov ntawv thov uas yuav tsum muaj kev cuam tshuam toughness ntawm qhov kub thiab txias.

Zuag qhia tag nrho, ASTM A515 Gr 70 steel yog ib qho kev ntseeg siab thiab pheej yig xaiv rau boilers thiab cov hlab ntsha siab ua haujlwm ntawm qhov nruab nrab mus rau qhov kub thiab txias. Nws lub zog siab, zoo corrosion kuj, thiab yooj yim ntawm vuam ua rau nws nrov nyob rau hauv ntau industries, xws li lub zog tsim, petrochemicals, thiab roj thiab roj.

Siab zog thiab lub teeb yuag: Tensile lub zog yog ntau tshaj 40% siab dua li ntawm cov pa roj carbon zoo tib yam, uas tuaj yeem txo cov khoom siv hlau siv thiab txo nqi tsheb thauj mus los thiab kev teeb tsa;

Zoo heev kub tsis kam: Ua haujlwm ruaj khov ntawm qhov kub siab ntawm 300-}350 degree, haum rau cov khoom siv xws li boiler nruas thiab cov cua kub siab;

Zoo weldability: Txhawb ntau txoj hauv kev suav nrog kev tiv thaiv hlau arc vuam, submerged arc vuam, thiab roj hlau arc vuam, nrog qis ua ntej - vuam preheating yuav tsum tau (80-120℃);

Corrosion kuj: Muaj ib qho kev kam rau me me hydrogen sulfide (H₂S) ib puag ncig, haum rau petrochemical pipelines;

Kev lag luam: Nta tus nqi nruab nrab ntawm cov qis- alloy steels, ua kev siv nyiaj txiag rau siab dua - lub zog alloy steels.

Petrochemical Kev Lag Luam:

Cov hlab ntsha tawg: Hydrofining reactors(kev ua haujlwm kub: 300-380 degree, siab: 4-8MPa);

Thaum tshav kub kub exchanger khoom: Plhaub ntawm plhaub-thiab- raj kub exchangers(kev ua haujlwm kub: 200-350 degree, siab: 3-7MPa);

Cov khoom sib cais: Regenerators ntawm catalytic cracking units, resistant rau me me corrosive media.

Fais Fab Kev Lag Luam:

Cov khoom siv boiler: Boiler drums(nrog siab -kub 300-} 350℃thiab high-pressure chav load ntawm 9-12MPa);

Cov cuab yeej pabcuam: Siab - cov cua kub siab(kev khiav hauj lwm kub: 250-300 degree, siab: 4-6MPa) thiab deaerator dej tso tsheb hlau luam.

Marine thiab Pipeline Engineering:

Hull cov qauv: Cov hlab ntsha siab thiab cov roj liquefied tso tsheb hlau luam, ua kom haum rau cov dej hiav txwv;

Pipeline systems: Petroleum pipelines, steam pipelines, thiab air pipelines, kom ntseeg tau ntev -lub sij hawm nruj.

Lwm cov teb:

Nuclear power auxiliary systems: Tsis yog- cov cuab yeej siv nuclear (xws li siab - cov cua sov siab), txo cov nqi thaum ua tau raws li qhov yuav tsum tau ua;

Cov khoom siv hydraulic: Siab-cov khoom siv bearing bearing dynamic loads.
