1. Lub ntsiab lus ntawm "1.0566"
Tus lej1.0566yog akhoom naj npawblos ntawm European standardTS EN 10027-2.
1. xxxxxxxxxxxxxx: Qhia tias nws yog hlau.
0566: Tus naj npawb tshwj xeeb uas tau muab rau cov hlau no cov tshuaj muaj pes tsawg leeg.
Cov khoom siv no suav nrog qib steelP295 HWMnyob rau hauv EN 10216 tus qauv rau seamless steel raj rau lub hom phiaj siab.
Yog li ntawd,1.0566=P295GH.
2. Kev tawg ntawm "P295GH"
Lub npe qib nws tus kheej qhia koj ntau txog cov khoom steel:
P: Stands for "Pressure" purpose. Qhov no tau lees tias nws yog tsim los tsim cov hlab ntsha siab, boilers, thiab lwm yam khoom siv siab -siab.
295: Qhia covyam tsawg kawg nkaus yield zog(ReH) ntawm chav tsev kub yog295 MPa ua(Megapascals). Qhov no yog ib qho kev ntsuas ntawm qhov kev ntxhov siab uas cov khoom pib deform plastically.
G: Sawv rau "Grain" refined. Qhov no txhais tau hais tias cov hlau tau dhau los ua ib qho kev kho cua sov tshwj xeeb (normalizing) los kho nws cov qauv nplej, uas txhim kho nws cov tawv tawv thiab cov khoom siv kho tshuab.
H: Qhia tias nws haum rauKub kub. Cov hlau no yog tsim los tuav nws lub zog thiab tiv thaiv creep (kev deformation qeeb hauv qhov kev ntxhov siab tas li) ntawm qhov kub siab, uas yog qhov tseem ceeb rau kev siv boiler.
3. Tshuaj muaj pes tsawg leeg
Cov tshuaj muaj pes tsawg leeg (los ntawm qhov hnyav, %) rau P295GH / 1.0566 feem ntau yog raws li hauv qab no (tus nqi yog qhov siab tshaj plaws tshwj tsis yog muab ntau yam):
| Element | Cov pa roj carbon (C) | Silicon (Si) | Manganese (Mn) | Phosphorus (P) | Sulfur (S) | Chromium (Cr) | Molybdenum (hli) |
|---|---|---|---|---|---|---|---|
| Cov ntsiab lus | 0.10 - 0.20 | 0.10 - 0.35 | 0.80 - 1.20 | Tsawg dua lossis sib npaug li 0.025 | Tsawg dua lossis sib npaug li 0.015 | Tsawg dua lossis sib npaug li 0.30 | Tsawg dua lossis sib npaug li 0.08 |
Cov ntsiab lus tseem ceeb ntawm Chemistry:
Cov pa roj carbon tsawg: Khaws cov hlau weldable thiab tiv thaiv kev tsim ntawm brittle microstructures.
Tsawg Sulfur & Phosphorus: Cov no yog impurities uas tuaj yeem txo qhov toughness thiab weldability. Ua kom lawv qis heev yog qhov tseem ceeb rau kev siv siab.
Manganese: Ua kom muaj zog thiab toughness.
4. Cov cuab yeej cuab tam tseem ceeb
Cov khoom siv tseem ceeb rau P295GH / 1.0566 kav dej ntawm chav tsev kub yog:
Yield zog (ReH): Ntau dua lossis sib npaug li 295 MPa
Tensile zog (Rm): 470 - 630 MPa
Elongation (A): Ntau dua lossis sib npaug li 24%(Qhov no yog ib qho kev ntsuas ntawm ductility -nws tuaj yeem ncav cuag ntau npaum li cas ua ntej tawg.)
5. Common International Equivalents
Nws tseem ceeb heev kom paub cov qib sib npaug hauv lwm cov qauv loj:
| Txuj | Qib sib npaug | Nco tseg |
|---|---|---|
| EN (Tebchaws Europe) | 1.0566 / P295GH | Thawj lub npe. |
| DIN (Lub teb chaws Yelemees) | HII | Ib lub npe German qub, tseem siv tau. |
| ASTM / ASME (USA) | SA-192 / SA-210 Qib A1 | Qhov ze tshaj plaws thiab ncaj tshaj qhov sib npaug rau boiler raj. |
| ISO | P295 HWM | Ib yam li EN lub npe. |
| JIS (Nyiv) | STPT370/STB340 | Cov qib zoo sib xws rau lub siab thiab cov raj boiler. |
Nco tseg:Thaum cov no yog qhov sib npaug, tuaj yeem muaj kev hloov pauv me ntsis hauv cov tshuaj muaj pes tsawg leeg lossis cov khoom siv kho tshuab. Rau cov ntawv thov tseem ceeb, cov lus qhia meej meej yuav tsum tau sab laj.
6. Cov ntawv thov tseem ceeb
Raws li lub npe "Boiler Steel Pipe" txhais tau hais tias, nws qhov kev siv tseem ceeb yog nyob rau hauv cov tshuab uas muaj qhov kub thiab txias:
Boiler Tubes: Ob leeg nyob rau hauv hluav taws- raj thiab dej- raj boilers rau lub zog tsim thiab muaj cua sov.
Superheaters thiab Reheaters: Cov seem ntawm lub boiler uas ua kom sov chav rau qhov kub siab heev.
Cov nkoj siab: Cov ntim khoom tsim los tuav cov pa roj lossis cov kua dej ntawm lub siab sib txawv ntawm qhov siab ntawm ib puag ncig.
Thaum tshav kub kub Exchangers: Qhov twg cov kua dej kub hloov cov cua sov mus rau cov dej txias.
High -Tub Piping Systems: Hauv cov chaw tsim hluav taws xob thiab cov txheej txheem kev lag luam.
Cov ntsiab lus
Hauv luv luv,1.0566 Carbon Steel Boiler Hlau Yeeb Nkabyog asiab-zoo, kub-tiv taus, siab- ntsuas carbon steeltshwj xeeb tsim los rau kev nyab xeeb thiab txhim khu kev qha nyob rau hauv siab - kub thiab siab - qhov chaw siab xws li boilers thiab siab hlab ntsha. Nws cov yam ntxwv tseem ceeb yog txhais los ntawm nws qib ENP295 HWM, kos npe rau qhov tsawg kawg nkaus tawm lub zog ntawm 295 MPa, cov nplej - cov qauv ua kom zoo, thiab tsim nyog rau kev ua haujlwm siab - kub.
