ASTM A105 Khoom Siv: Ua tiav Kev Tshwj Xeeb
1. Cov ntsiab lus tseem ceeb
ASTM A105yog aCov Hlau HlauTshwj Xeeb RauFoob Cheebtsam(flanges, fittings, li qub) siv nyob rau hauvSiab Piping TshuabCov. Nws yog feem ntau cov cuab yeej siv rau cov roj carbon hlau flanges nyob rau hauv ASME B16.5 \/ B16.47.
2. Tshuaj lom neeg sib xyaw (ASTM A105 xav tau)
| Lub ntsiab | Cov ntsiab lus (%) | Lub ntsiab | Cov ntsiab lus (%) |
|---|---|---|---|
| Carbon (c) | Tsawg dua los yog sib npaug rau 0. 35 | Manganese (mn) | 0.60–1.05 |
| Phosphorus (p) | Tsawg dua li lossis sib npaug rau 0. 035 | Sulphur (s) | Tsawg dua los yog sib npaug rau 0. 040 |
| Silicon (si) | 0.10–0.35 | Tooj Liab (Cu) | Tsawg dua los yog sib npaug rau 0. 40 |
| Npib tsib caug (ni) | Tsawg dua los yog sib npaug rau 0. 40 | Chromium (cr) | Tsawg dua los yog sib npaug rau 0. 30 |
| Molybdenum (mo) | Tsawg dua los yog sib npaug rau 0. 12 | Vanadium (V) | Tsawg dua los yog sib npaug rau 0. 08 |
(Nco tseg: Cov ntsiab lus txawv txawv ua kom muaj zog Weldability thiab lub zog.)
3. Cov Khoom Siv Kho Tshuab
| Ntiag tug | Tus nqi | Kuaj Tus Qauv |
|---|---|---|
| Lub zog tensile | Ntau dua los yog sib npaug rau 485 mpa | ASTM A370 |
| Paib lub zog | Ntau dua los yog sib npaug rau 250 MPa | ASTM A370 |
| Elongation (50 hli) | Ntau dua los yog sib npaug rau 22% | ASTM A370 |
| Hardness (Brinell) | Tsawg dua los yog sib npaug rau 187 hb | Astm E10 |
4. Cov yam ntxwv tseem ceeb ntawm ASTM A105
✅ Forged cov qauv: Superior Grain Flow Vs pov \/ txiav cov ntaub ntawv
✅ Hwj txwv: Tau tshaj Smaw, GTaw, pom txoj hauv kev
✅ Qhov ntsuas kub ntau: {-29 degree rau 425 degree (Rau qis temps, siv ittm A350 lf2)
✅ Nqi-Zoo: Tus nqi qis dua cov nqi nqus \/ cov hlau nplaum
5. Cov Khoom Siv Khoom Tib
Flanges(ASME B16.5 \/ B16.47)
Cov yeeb nkab fittings(ASME B16.9 \/ B16.11)
Lub cev(API 6D \/ ASME B16.34)
Forged Nqis(rau kev machining cov chaw ua haujlwm)
6. Piv rau cov ntaub ntawv zoo sib xws
| Khoom | ASTM A105 | ASTM A350 LF2 | AISI 304 |
|---|---|---|---|
| Ntaus | Cov Hlau Hlau | Low-temp Carbon Hlau | Stainless hlau |
| Temp ntau | {{0 {} degree ~ 425 degree | -46 degree ~ 340 degree | -254 degree ~ 816 degree |
| Corrosion Kuj | Qi | Qi | Siab |
| Raug | Tsis-Corrosive Tshuab | Cryogenic Service | Corrosive ib puag ncig |
7. Kev tsim qauv txheej txheem
Kev zam: Kub forging ntawm 1100 degree -900 degree
Kev Kho Cua Sov: Normalizing (yeem rau A105N)
Ntaub: CNC Tig \/ Drilling rau Asme Qhov Ntev
Kev kuaj: Hydrostatic, Hardness, PMI (ib astm 961)
8. Qhov txwv thiab kev xaiv lwm yam
⚠ Tsis pom zoo rau:
Cov Medosive Media (Siv Hlau Stainless)
Temperatures >425 Qib (Siv ASTM A694 F60 \/ F65)
Cryogenic Service hauv qab no -29 degree (siv ittm A350 LF2)
9. Ntawv pov thawj & ua raws
ASME Seem II: Pom zoo rau cov hlab ntsha siab siv
Ped 2014\/68 \/ EU: CE khij rau EU kev lag luam
NACE MR0175: Tsawg H2S Kev Pab Ua Raws Cai
