1.0345yog ib qho khoom tsim los ntawm lubEuropean qauv EN 10216-1, uas npog seamless steel raj rau lub hom phiaj siab.
Hom Lub Npe:Nws yog feem ntau hu uaP235GH.
Hom:Nws yog ibcarbon{0}}manganese hlau.
Kev Siv Tseem Ceeb:Nws yog tsim tshwj xeeb rausiab thiab siab -kev pabcuam kub, ua nws classic "boiler steel" los yog "siab hlab ntsha steel."
Tus naj npawb "1.0345" yog cov khoom siv, thaum "P235GH" yog lub npe qib steel. Koj yuav pom lawv siv interchangeably.
Ntsiab Specifications thiab Properties
Lub npe "P235GH" tawg raws li hauv qab no:
P:Stands rau "Pressure" lub hom phiaj.
235:Qhia qhovYam tsawg kawg uas tau teev tseg lub zog (ReH) ntawm chav tsev kubyog 235 MPa.
G:Stands rau "Grain" tswj (ua tiav los ntawm kev kho Aluminium, uas ua kom zoo dua cov qauv nplej kom zoo dua toughness).
H:Qhia tias haum rauSiab -kubkev pabcuam.
Raws li EN 10216-1:
Chemical Composition (Kwv yees% los ntawm qhov hnyav):
| Lub ntsiab | Cov ntsiab lus (%) |
|---|---|
| Cov pa roj carbon (C) | max 0.16 |
| Manganese (Mn) | 0.80 - 1.20 |
| Silicon (Si) | 0.40 max |
| Phosphorus (P) | max 0.025 |
| Sulfur (S) | max 0.015 |
| Aluminium (Al) | min 0.020 (rau kev tswj cov nplej) |
Cov ntsiab lus qis carbon ua kom zoo weldability, thaum manganese muab lub zog.
Mechanical Properties (ntawm chav tsev kub):
| Khoom | Tus nqi |
|---|---|
| Yield Strength (ReH), min | 235 MPa rau |
| Tensile zog (Rm) | 360 - 510 MPa |
| Elongation (A), min | 25% |
High -Tsev Khoom Cuab Yeej:
Ib qho laj thawj tseem ceeb rau nws siv hauv boilers yog nws lub peev xwm los tswj lub zog ntawm qhov kub siab. Nws muaj ib tug txhaisyam tsawg kawg nkaus yield zog ntawm siab kub(piv txwv li, tseem tshaj 150 MPa ntawm 300 degree).
Cov ntawv thov siv
1.0345 / P235GH boiler raj yog siv nyob rau hauv cov tshuab uas cov khoom nyob rau hauv lub siab sab hauv thiab feem ntau nyob rau hauv high kub.
Fais fab Generation Boilers:Rau ob qho tib si dej raj thiab hluav taws kub boilers.
Superheaters thiab Kub Exchangers:Hauv cov seem uas muaj qhov kub thiab txias.
Cov nkoj siab:Rau ntau yam kev lag luam.
Cov kav dej kub thiab chav dej:Hauv kev lag luam cov nroj tsuag thiab hauv cheeb tsam cua sov tshuab.
Nuclear fais fab nroj tsuag:Nyob rau hauv lub koom haum pab (tsis yog lub core reactor siab hlab ntsha).
Qib sib npaug hauv Lwm Cov Qauv
1.0345 / P235GH yog cov khoom siv ntau heev, thiab nws muaj qhov sib npaug ncaj qha lossis zoo sib xws hauv lwm cov qauv thoob ntiaj teb loj.
| Txuj | Qib sib npaug | Nco tseg |
|---|---|---|
| ISO 9328-2 | P235GH | Direct sib npaug |
| ASTM A192 / A210 / ASTM A192 / ASTM A210 Cov Lus Qhia Tshwj Xeeb | A192 | Nyob ze heev; A192 yog tshwj xeeb rau siab - siab boiler raj. |
| TIAB SA 17175 | qib 35.8 | Ib qib zoo sib xws thiab keeb kwm zoo li German qib. |
| JIS G3461 | SWB 340 | Japanese txuj rau boiler thiab tshav kub exchanger raj. |
Nco tseg:Txawm hais tias cov qib no zoo sib xws, lawv tsis yog tshuaj lom neeg thiab tsis zoo ib yam. Kev hloov pauv yuav tsum tsuas yog ua tiav tom qab sab laj txog cov qauv tsim qauv thiab ua kom cov khoom ua tau raws li txhua qhov kev xav tau tshwj xeeb rau daim ntawv thov.
Manufacturing thiab Fabrication
Kev tsim khoom:Cov kav dej no feem ntau yogseamless, txhais tau tias lawv yog tsim los ntawm ib tug khoom billet tsis muaj welded seam. Qhov no muab lub zog zoo ib yam thiab tseem ceeb heev rau siab -siab ncaj ncees.
Weldability:1,0345 uazoo heev weldabilityvim nws cov ntsiab lus qis carbon. Cov txheej txheem vuam zoo li SMAW (Stick), GTAW (TIG), thiab GMAW (MIG) tuaj yeem siv. Preheating feem ntau tsis tas yuav tsum tau ua rau nyias nyias tab sis yuav tsum tau soj ntsuam raws li thickness thiab ambient tej yam kev mob.
Kev tsim:Nws muaj qhov txias txias zoo- tsim cov khoom, cia nws khoov thiab flanged thaum tsim cov tshuab boiler.
Kev txiav txim siab tseem ceeb
Tsis yog rau Corrosive Environments:Raws li cov pa roj carbon steel, nws muaj kev txwv tsis pub ua rau corrosion. Nyob rau hauv ib puag ncig nrog cov dej oxygenated los yog lwm yam corrosive, kev tiv thaiv kev tiv thaiv (xws li kev kho dej) lossis lwm yam khoom siv (stainless steel) yuav tsim nyog.
Kub txwv:Thaum zoo rau qhov kub siab, nws muaj qhov ntsuas kub siab (feem ntau nyob ib puag ncig 450-500℃rau kev pabcuam mus sij hawm ntev). Nyob rau hauv tas li ntawd, creep lub zog txo qis heev.
Quality thiab Certification:Nco ntsoov xyuas cov yeeb nkab xa khoom muab aDaim ntawv pov thawj zeb xeem (MTC)los yogEN 10204 3.1/3.2 daim ntawv pov thawj. Cov ntaub ntawv no tau lees paub tias cov khoom tau raug sim thiab ua raws li EN 10216-1 tus qauv.
Cov ntsiab lus
1.0345 (P235GH) Carbon Steel Boiler Yeeb Nkabyog ib qho kev txhim khu kev qha, tus nqi- siv tau zoo, thiab siv dav siv los tsim cov khoom siv siab hauv boilers, kub exchangers, thiab cov hlab ntsha siab. Nws zoo heev ua ke ntawm lub zog, weldability, thiab siab -kub kev ua tau zoo ua rau nws yog ib qho tseem ceeb lub tsev thaiv rau lub hwj chim thiab txheej txheem industries.
Thaum muab cov khoom no, nco ntsoov qhia tag nrho cov qauv (piv txwv li,TS EN 10216-1 P235GH) kom ntseeg tau tias koj tau txais cov khoom raug rau koj daim ntawv thov.
