P235TR1 Carbon Steel Boiler Hlau Yeeb
P235TR 1yog European standard qib ntawmnon- alloy zoo- steel tubetsim tshwj xeeb rausiab lub hom phiaj thiab siab kub kev pab cuam, xws li hauv boilers thiab tshav kub exchangers. Nws yog txhais raws li European tus qauvTS EN 10216-2: Seamless steel raj rau lub hom phiaj siab - Kev xa tawm cov xwm txheej - Ntu 2: Cov hlau tsis muaj hlau thiab hlau alloy nrog cov khoom ntsuas kub siab.
Cov yam ntxwv tseem ceeb:
Khoom siv:Tsis yog- alloy (carbon) steel nrog cov qauv zoo.
Daim Ntawv Thov Tseem Ceeb:Manufacturing ntawmboilers, superheaters, thiab cov hlab ntsha siabqhov twg cov khoom raug rau sab hauv siab thiab siab kub.
Cov khoom tseem ceeb:lavyam tsawg kawg nkaus yield zogthiabtensile zogntawm chav tsev kub, raws li tau teev tsegcreep kujthiabsiab -kub muaj zogkhoom.
Kev tsim khoom:Feem ntau muab raws liseamless rajkom muaj kev ncaj ncees nyob rau hauv siab.
Lub ntsiab lus npe:
P:Stands rau "Pressure" lub hom phiaj.
235:Qhia qhovYam tsawg kawg nkaus yield zog (ReH)nyob rau hauv MPa ntawm chav tsev kub.
TR 1:Sawv rauTube, rotor, thiab siab hlab ntsha steel, Qib 1. Cov qeb "TR" txhais tau hais tias cov hlau uas muaj qhov ntsuas qhov ntsuas kub.
Technical Parameter Table
Cov lus hauv qab no qhia txog cov tshuaj lom neeg tseem ceeb thiab cov khoom siv kho tshuab raws li EN 10216-2.
Table 1: Chemical Composition (Qhov tseem ceeb tshaj plaws hauv % los ntawm qhov hnyav)
| Element | Cov pa roj carbon (C) | Silicon (Si) | Manganese (Mn) | Phosphorus (P) | Sulfur (S) | Aluminium (Al) |
|---|---|---|---|---|---|---|
| Tus nqi | 0.13 | 0.35 | 0.70 - 1.20 | 0.025 | 0.020 | ≥ 0.020 |
Lus Cim: Cov qauv zoo yog ua tiav los ntawm kev kho aluminium (Al ntsiab lus).
Table 2: Chav Kub Kub Mechanical Properties
| Khoom | Yield Strength (ReH), min | Tensile zog (Rm) | Elongation (A), min |
|---|---|---|---|
| Tus nqi | 235 MPa rau | 360 - 480 MPa | 25% |
Table 3: Piv txwv ntawm Cov Cuab Yeej Cuab Yeej Ua Ntej (Qhov Tsawg Tshaj Tawm Tawm Zog - Rp0.2, hauv MPa)
| Kev ntsuas kub (°C) | 100 | 150 | 200 | 250 | 300 | 350 | 400 | 450 |
|---|---|---|---|---|---|---|---|---|
| Rp 0.2, min (MPa) | 186 | 167 | 150 | 139 | 131 | 125 | 119 | 114 |
Nco tseg: Cov nqi hauv Table 3 yog rau siv. Cov txiaj ntsig tau lees paub tseeb nyob ntawm phab ntsa thickness thiab tau teev nyob rau hauv tus qauv cov khoom ntxiv. Kev tsim qauv yuav tsum ua raws li tus qauv kev lees paub kev ntxhov siab rau kev suav.
Common Equivalent Qib
| Txuj | Qib sib npaug | Lus ceeb toom |
|---|---|---|
| TS EN ISO 9329-2 | P235GH | Zoo sib xws heev, feem ntau siv los ua qhov sib npaug. |
| TIAB SA 17175 | Qhov 35.8 / St35.8III | Cov npe German qub, daim ntawv thov zoo sib xws. |
| ASTM/ASME | SA-192 (rau cov raj kub siab boiler) los yog SA-106 B | Tsis ncaj equivalents. SA-106 B yog rau cov kev pabcuam kub kub tab sis txawv qhov tshwj xeeb. Kev xaiv yuav tsum muaj kev sib piv kom ntxaws. |
Daim ntawv thov
Boiler Tubes:Cov kav dej phab ntsa, cov khoom siv nyiaj txiag, thiab cov khoom siv hluav taws xob superheater hauv cov pob txha roj hluav taws xob thiab cov boilers muaj.
Thaum tshav kub kub Exchanger Tubes:Rau cua sov nto nyob rau hauv ntau yam txheej txheem industries.
Siab Piping:Rau chav dej thiab dej kub kab hauv qhov ntsuas kub thiab siab txwv.
Hauv cov ntsiab lus,P235TR 1yog ib tug qauv European carbon steel qib rau seamless siab raj, muab ib tug sib npaug ntawm lub zog, formability, thiab guaranteed kev ua tau zoo ntawm siab kub, ua rau nws yog ib qho tseem ceeb cov ntaub ntawv rau boiler kev tsim kho.
