Sib sib zog nqus Dive: ASTM A479 (The "Pressure" Standard)
CovASTM A479 (los yog ASME SA 479)specification yog ib daim ntawv qhia kev uas npog stainless hlau tuav tshwj xeeb rau siv nyob rau hauv lub siab systems.
Vim tias tsis ua haujlwm hauv lub nkoj siab tuaj yeem ua rau muaj kev puas tsuaj loj, A479 yuav tsum:
- Plaub Steel Qeb:Nws nruj me ntsis categorizes cov ntaub ntawv rau hauv Austenitic, Austenitic-Ferric (Duplex), Ferritic, thiab Martensitic.
- Strict Property Values:Lub zog tensile, yield zog, elongation, thiab hardness yuav tsum tau raws li qhov tseeb raws li qhov tshwj xeeb cua sov- kho mob.
- ASME Alignment:Nws yog tsim los ua haujlwm nrog ASME cov lej, ua rau nws "mus-rau" rau kev lag luam roj, roj, thiab hluav taws xob.
Sib sib zog nqus Dive: ASTM A276 (Tus Qauv "Kev Lag Luam")
ASTM A276, ASTM A276yog qhov feem ntau specification rau stainless hlau tuav. Nws muaj ntau yam thiab suav nrog ntau yam "dawb-machining" thiab cov qib txheem.
- Versatility:Nws yog siv thaum qhov kev txhawj xeeb tseem ceeb yog cov khoom muaj peev xwm los tiv thaiv corrosion los yog muab cov qauv kev ncaj ncees nyob rau hauv uas tsis yog -pressurized ib puag ncig.
- Muaj:Vim tias nws yog tus qauv "general", A276 cov ntaub ntawv feem ntau tau yooj yim dua nyob rau hauv Tshuag hla ntau qhov ntau thiab tsawg thiab cov duab.
- Kev txwv:Nws tshwj xeeb tsis suav nrog bar raureforging.
Tus nqi thiab kev ua lag luam muaj
Feem ntau, ib qho ntawm cov hlau tsis muaj steel hlau yuav yog "dual- ntawv pov thawj," txhais tau tias nws ua tau raws li qhov yuav tsum tau muaj ntawm ASTM A276 thiab ASTM A479.
- Nqe:Feem ntau, qhov sib txawv ntawm tus nqi yog qhov tsawg yog tias qib yog ntau (xws li 316L). Txawm li cas los xij, yog tias kev kuaj tshwj xeeb lossis cov ntaub ntawv yuav tsum tau ua raws li A479 / SA479, cov nqi yuav nce ntxiv.
- Ntiaj teb no Source:Rau cov haujlwm thoob ntiaj teb, xyuas kom koj tus neeg muag khoom muab qhov tseebMTR (Cov ntaub ntawv ntsuam xyuas)qhia tias cov kev kho cua sov tshwj xeeb thiab cov kev sim tshuab ua haujlwm raws li tus qauv uas koj cov engineers tau teev tseg.
Cov lus nug nquag nug (FAQ)
1. Puas tuaj yeem siv ASTM A276 hloov ASTM A479?
Feem ntau, tsis yog, yog tias daim ntawv thov cuam tshuam nrog -siab boilers lossis cov hlab ntsha. Thaum cov tshuaj muaj pes tsawg leeg feem ntau zoo ib yam, ASTM A479 yuav tsum tau kuaj xyuas cov cuab yeej tshwj xeeb thiab kev kho cua sov los ntawm ASME cov lej kev nyab xeeb uas ASTM A276 tsis npog.
2. Dab tsi yog daim ntawv thov tseem ceeb ntawm ASTM A479?
ASTM A479 feem ntau yog siv rau kev tsim cov boilers thiab cov hlab ntsha siab. Nws nquag teev tseg rau valve stems, fittings, thiab sab hauv cov khoom nyob rau hauv cov roj, roj, thiab nuclear industries.
3. Puas yog ASTM A276 npog tag nrho cov hlau tsis zoo?
ASTM A276 npog kub-tiav lossis txias- cov khoom tiav, suav nrog cov voj voog, squares, hexagons, thiab kub- dov lossis extruded duab zoo li lub kaum sab xis, tees, thiab cov kab. Txawm li cas los xij, nws tshwj xeeb tsis suav nrog cov tuav rau reforging.
4. Puas yog ASTM A276 thiab A479 tus nqi sib txawv?
Rau cov qib txheem zoo li 304 lossis 316, tus nqi feem ntau zoo sib xws. Txawm li cas los xij, A479 tuaj yeem nqa tau tus nqi yog tias qhov kev sim tshwj xeeb ntxiv lossis dual- ntawv pov thawj (ASME SA479) yog xav tau rau ib qhov project.
