Txheej txheem cej luam
Lub npe1.0565yog tus qauvEN (European Norm) cov ntaub ntawv tus lej. Nws poob rau hauv qeb ntawm cov pa roj carbon-manganese steels tshwj xeeb tsim los siv rau qhov kub siab, ua rau nws xaiv classic rauboiler tubesthiabseamless siab cov kav dej.
Qhov feem ntau sib thooj steel qib rau tus lej no yogP265GHRaws li EN 10216 tus qauv.
1. Cov ntsiab lus tseem ceeb thiab cov qauv sib npaug
EN Number: 1.0565
EN Steel Qib: P265GH
P= Lub hom phiaj siab
265= Tsawg tshaj tawm lub zog (hauv MPa) ntawm chav tsev kub
G= Manganese (Mn) alloyed
H= Haum rau siab - kev pabcuam kub
Main Standard: TS EN 10216-2: Seamless steel tubes rau lub hom phiaj siab - Kev xa tawm cov xwm txheej - Ntu 2: Tsis yog- alloy thiab alloy steel hlab nrog qhov ntsuas kub siab.
Common Equivalent Standards:
ASTM A192 / A213 T11 Cov Lus Qhia- Tsis yog qhov sib npaug ncaj qha. P265GH yog cov hlau tsis yog- alloy steel, thaum ASTM boiler raj zoo li T11 yog chromium-molybdenum alloys. Qhov ze dua ASTM sib npaug rau kev siv boiler dav dav yuav yogASTM A210 A1, tab sis chemical thiab mechanical zog tsis zoo ib yam. P265GH feem ntau yog EN- qib tshwj xeeb.
2. Chemical Composition (Hom raws li EN 10216-2)
Cov muaj pes tsawg leeg yog sib npaug los muab cov weldability zoo thiab lub zog ntawm qhov kub thiab txias.
| Element | Kev sib xyaw (%) |

| Molybdenum (hli) | max . 0.08 |
| Nickel (Ni) | max . 0.30 |
| Aluminium (Al) | min . 0.020 |
Lus Cim: Cov pa roj carbon tsawg thiab cov ntsiab lus sulfur / phosphorus ua kom zoo weldability thiab toughness.
3. Mechanical Properties
Qhov "H" hauv P265GH txhais tau tias nws cov khoom siv kho tshuab tau lav ntawm qhov kub siab.
Ntawm chav kub:
Yield zog (Rp0.2):min . 265 MPa
Tensile zog (Rm):410 - 530 MPa
Elongation (A):min . 24% (vim muaj qhov ntev ntawm lub raj)
Ntawm qhov kub siab:
Ib qho tseem ceeb ntawm cov hlau no yog nws qhov tsawg kawg nkaus tawm lub zog ntawm qhov kub thiab txias. Piv txwv li:
Thaum 300 degree:Min. Tawm Zog yog ~ 186 MPa
Thaum 350 degree:Min. Tawm Zog yog ~ 167 MPa
Thaum 400 degree:Min. Tawm Zog yog ~ 150 MPa
Cov ntaub ntawv no yog qhov tseem ceeb rau cov kws tsim qauv tsim cov boilers thiab cov hlab ntsha siab kom muaj kev nyab xeeb hauv kev ua haujlwm.
4. Cov yam ntxwv tseem ceeb thiab qhov zoo
Siab -Tsub Muaj Zog:Nws qhov txiaj ntsig tseem ceeb yog tswj xyuas cov qauv kev ntseeg siab thiab siab -cov kabmob muaj peev xwm ntawm qhov kub thiab txias (feem ntau txog ~ 450-500℃).
Zoo Weldability:Qhov sib npaug qis qis tso cai rau nws tuaj yeem welded tau yooj yim siv txoj hauv kev yam tsis muaj ua ntej - cua sov lossis tom qab - vuam cov cua sov hauv feem ntau (txawm tias cov lej tshwj xeeb thiab phab ntsa tuab yuav tsum tau ua raws).
Formability zoo:Nws tuaj yeem khoov thiab flanged nrog cov txheeb ze yooj yim, uas yog qhov tseem ceeb rau kev tsim cov tshuab boiler complex.
Tus nqi -zoo:Raws li cov hlau tsis yog - alloy carbon steel, nws yog kev lag luam ntau dua li cov hlau alloy xws li T11, T22, lossis P91, ua rau nws zoo tagnrho rau cov kev pabcuam hnyav dua.
Zoo heev thermal conductivity:Cov pa roj carbon steel muaj cov khoom siv hluav taws xob zoo, uas yog qhov tseem ceeb rau kev ua haujlwm zoo ntawm boiler.
5. Kev siv ntau
P265GH (1.0565) hlab yog siv nyob qhov twg muaj qhov xav tau rau cov kav dej seamless uas tuaj yeem tiv taus qhov siab thiab kub siab. Cov ntawv thov ib txwm muaj xws li:
Dej Tube Boilers:Rau ob qho tib si tsim thiab superheater raj.
Hluav Taws Kub Boilers:Cov pa luam yeeb.
Kub Exchangers thiab Condenser
Superheated Chav Pipes
Siab -Tsuas Kub Siab Nkoj
Piping Systems rau dej kub thiab saturated chav
6. Kev txiav txim siab tseem ceeb rau kev siv
Corrosion Resistance:Qhov no yog cov pa roj carbon steel thiab muaj kev tiv thaiv corrosion. Nws yooj yim rau xeb thiab oxidation. Hauv kev siv boiler, dej chemistry yuav tsum tau ua tib zoo tswj kom tsis txhob muaj kev cuam tshuam sab hauv.
Kub txwv:Thaum zoo rau qhov kub siab, nws tsis haum rau siab heev -kub los yog siab - cov ntawv thov siab qhov twg creep lub zog yog qhov tseem ceeb. Rau qhov xav tau ntau dua, qis- alloy steels (piv txwv li, 1.7335 / 13CrMo4-5) lossis stainless hlau yog siv.
Ua raws li:Yuav tsum xyuas kom meej tias cov khoom tau muab nrog daim ntawv pov thawj tsim nyog (xws li 3.1B lossis 3.2 raws li EN 10204) kom lav tias nws ua tau raws li cov cai ntawm EN 10216-2.
Cov ntsiab lus
1.0565 Carbon Steel Boiler Yeeb Nkab (P265GH)yog ib qho kev txhim khu kev qha, tus nqi- siv tau, thiab siv dav siv los tsim cov khoom siv siab hauv cov boilers thiab cov khoom siv hluav taws xob ua haujlwm ntawm qhov nruab nrab kub. Nws zoo heev ua ke ntawm weldability, siab - kub lub zog, thiab formability ua rau nws yog ib qho tseem ceeb lub tsev thaiv nyob rau hauv thermal zog thiab txheej txheem industries.
Thaum muab cov khoom siv no, nco ntsoov qhia tus qauv ua tiav, piv txwv li:Seamless Steel Tube EN 10216-2 / 1.0565 / P265GH.
