JIS G 3466 yog dab tsi?
TIAB SA 3466yog Japanese Industrial Standard uas qhia txog cov kev cai raucarbon steel kav siv rau boiler thiab tshav kub exchanger daim ntaub ntawv.
Cov yam ntxwv tseem ceeb ntawm cov kav dej ua rau tus qauv no yog lawv lub peev xwm los tiv thaiv kev kub siab thiab kub. Lawv feem ntau yogseamlessthiab tau tsim los siv rau hauv cov kev pabcuam tseem ceeb xws li:
Boiler Superheaters
Boiler Reheaters
Economizers
Thaum tshav kub kub Exchangers
Lwm cov khoom siv ntawm cov hlab ntsha siab
Cov qib tseem ceeb thiab lawv cov khoom
JIS G 3466 txhais tau ntau qib, nrog rau feem ntauSTB340, STB410, thiab STB510. Tus "STB" sawv cev rau "Seamless Tube rau Boiler," thiab tus lej qhia txog qhovyam tsawg kawg nkaus tensile zoghauv MPa.
Nov yog cov ncauj lus kom ntxaws ntawm cov qib uas muaj ntau tshaj plaws:
1. TSI 340
Qhov no yog qib qis - carbon steel qib nrog zoo weldability thiab formability.
Chemical Composition (kwv yees):
Carbon (C): Tsawg dua lossis sib npaug li 0.18%
Manganese (Mn): 0.30 - 0.60%
Phosphorus (P): Tsawg dua lossis sib npaug rau 0.035%
Sulfur (S): Tsawg dua lossis sib npaug rau 0.035%
Mechanical Properties:
Tensile zog:340 MPa (min)
Yield zog:185 MPa (min)
Elongation:35% (min)
Yam ntxwv:Zoo ductility, yooj yim rau weld, haum rau qis kub thiab siab kev pab cuam.
2. SWB 410
Qhov nruab nrab - qib carbon steel muab lub zog siab dua STB340.
Chemical Composition (kwv yees):
Carbon (C): 0.10 - 0.25%
Manganese (Mn): 0.30 - 0.60%
Phosphorus (P): Tsawg dua lossis sib npaug rau 0.035%
Sulfur (S): Tsawg dua lossis sib npaug rau 0.035%
Mechanical Properties:
Tensile zog:410 MPa (min)
Yield zog:245 MPa (min)
Elongation:30% (min)
Yam ntxwv:Qhov zoo sib npaug ntawm lub zog thiab formability.
3. TSI 510
Ib qib siab dua - qib carbon steel, feem ntau siv qhov twg yuav tsum muaj zog siv tshuab ntau dua.
Chemical Composition (kwv yees):
Carbon (C): 0.15 - 0.30%
Manganese (Mn): 0.60 - 0.90%
Phosphorus (P): Tsawg dua lossis sib npaug rau 0.035%
Sulfur (S): Tsawg dua lossis sib npaug rau 0.035%
Mechanical Properties:
Tensile zog:510 MPa (min)
Yield zog:285 MPa (min)
Elongation:25% (min)
Yam ntxwv:Lub zog siab dua vim muaj cov pa roj carbon ntau ntxiv thiab manganese cov ntsiab lus. Weldability tej zaum yuav xav tau kev saib xyuas ntau dua (ua ntej- cua sov lossis tom qab- kev kho cua sov).
Kev sib piv nrog International Standards
JIS G 3466 cov kav dej ua haujlwm zoo ib yam li cov kav dej los ntawm lwm cov qauv thoob ntiaj teb siv rau tib lub hom phiaj. Nov yog qhov kev sib piv ntxhib:
| TIAB SA 3466 | ASTM A179 / A192 | TIAB SA 17175 | GB 5310 (Suav Std.) |
|---|---|---|---|
| SWB 340 | Zoo ib yam li A179 (Low-C) | Zoo ib yam li St35.8 | Zoo ib yam li 20G |
| SWB 410 | Zoo ib yam li A192 (Med-C) | Zoo ib yam li St45.8 | - |
| SWB 510 | - | - | - |
Lus Cim Tseem Ceeb:Thaum cov qhab nia zoo sib xws, lawv yogtsis yog ib txwm ncaj qha interchangeable. Cov tshuaj muaj pes tsawg leeg txwv, kev kho cua sov, thiab cov txheej txheem kuaj yuav txawv. Nco ntsoov sab laj tus qauv tshwj xeeb thiab cov qauv tsim tshwj xeeb thaum xaiv cov khoom siv.
Cov ntawv thov siv
Vim lawv qhov siab -siab thiab siab -kub muaj peev xwm, JIS G 3466 kav feem ntau yog siv rau hauv:
Kev tsim hluav taws xob:
Superheater thiab reheater tubes hauv cov thee- raug rho tawm haujlwm, roj- raug rho tawm haujlwm, thiab biomass fais fab nroj tsuag.
Cov kav dej phab ntsa thiab cov kav dej economizer hauv boilers.
Petrochemical Kev Lag Luam:
Thaum tshav kub kub exchanger raj nyob rau hauv refineries thiab tshuaj ua cov nroj tsuag.
Tube rau hluav taws xob cua sov thiab txheej txheem cua sov.
Muaj boilers:
Ntau cov raj thiab cov kav dej hauv kev lag luam - nplai chav boilers.
Cov ntsiab lus tseem ceeb uas yuav tsum nco ntsoov
Seamless Kev Tsim Kho:JIS G 3466 kav dej yuav luag tshwj xeeb seamless, uas muab superior siab ncaj ncees piv rau welded kav.
High -Tsev Kev Pabcuam:Lawv tau tsim thiab sim ua kom muaj kev ntseeg siab nyob rau lub sijhawm ntev ntawm qhov kub thiab txias.
Qib Xaiv:Qhov kev xaiv ntawm qib (STB340, STB410, thiab lwm yam) nyob ntawm tus qauv tsim, qhov kub thiab txias, thiab qhov xav tau lub zog ntawm daim ntawv thov tshwj xeeb.
Kev Tswj Xyuas Zoo:Tus txheej txheem tswj hwm nruj tsis- kuaj kev puas tsuaj (xws li eddy tam sim no lossis hydrostatic testing) kom ntseeg tau tias cov kav dej tsis muaj qhov tsis xws luag uas tuaj yeem ua rau tsis ua haujlwm.
Hauv cov ntsiab lus,JIS G 3466 yog tus qauv tseem ceeb rau siab -cov pa roj carbon steel yeeb nkab zoo tseem ceeb rau kev nyab xeeb thiab ua haujlwm tau zoo ntawm boilers thiab kub exchangers thoob plaws lub zog thiab cov txheej txheem kev lag luam.
