ASTM A106 thiab ASTM A500 yog ob tus qauv steel hlau nyob rau hauv kev tsim cov hom phiaj tsim, cov khoom siv, kev tsim khoom thiab kev tsim cov xwm txheej. Cov hauv qab no yog ib qho kev sib piv tshwj xeeb los ntawm cov tseem ceeb tshaj plaws:
1. Cov ntsiab lus siv thiab tsim qauv
Xws liTM A106
- Daim Ntawv Thov:Tshwj xeebTsim los rau kev thauj mus los ntawm high - kub thiab high {{1} Lub raj mis siab, nws yog ib qho kev siv hluav taws xob siab, cov tshuaj lom neeg thiab hluav taws xob.
- Hom Phiaj Tsim:Qhia meej qhov kev siab siab, kub ua hauj thiab sealing kev ua tau zoo thiab muaj peev xwm tiv thaiv ntev {}}} kub nkag thiab lub siab txias.
- Cov xwm txheej raug:Roj Refinery Pipelines, Boiler Tshuab, High- kev hloov pauv kub.
ATM A500
- Daim Ntawv Thov:Nws kuvS tsim nyog rau cov khoom zoo li qub ntsaws - cov qauv qauv thiab kev pab cuam yam, suav nrog cov neeg txheeb xyuas cov khaub ncaws, thiab cov pob txha tsev.
- Hom Phiaj Tsim:Txhim kho cov qauv muaj zog, khoov thiab compressive thiab qhov tseeb raug, nrog tsom rau kev thauj khoom ruaj khov hauv qab cov txheej txheem txias
- Cov xwm txheej raug:Hlau tsim vaj tse, choj trusses, tsheb chassis.
2. Cov Khoom Siv Khoom Siv thiab Kev Ua Tau Zoo
Kev sib piv ntawm cov kev hloov hluav taws xob:
| Chaw ua uas tsis tau haus | ASTM A106 (Chav Kawm B) | ASTM A500 (Chav Kawm B) |
| Lub zog tensile | Ntau dua los yog sib npaug rau 60,000 psi | 58,000-80,000 psi |
| Paib lub zog | Ntau dua los yog sib npaug rau 35,000 psi | Ntau dua los yog sib npaug rau 46,000 psi |
| Elongation | Ntau dua los yog sib npaug rau 30% | Ntau dua los yog sib npaug rau 23% |
Nco tseg: C / D Qib C / D muaj lub zog siab dua (tawm lub zog ntau dua los yog sib npaug rau hnyav {{3} duty} Duty wrectures.
Tshuaj lom neeg sib txawv
ASTM A106:
Cov pa roj carbon yog tsawg dua los yog sib npaug rau 0.30%, cov ntsiab lus manganese yog 0.29%) thiab phosphorus (tsawg dua los yog sib npaug los txo cov siab kub.
ASTM A500:
Qhov ntau ntawm cov pa roj carbon thiab cov ntsiab lus manganese yog dav (piv txwv, cov pa roj hmab tsawg dua los yog sib npaug lossis sib npaug ntawm 0.05% tsawg dua lossis sib npaug rau 0.04%).
3. Kev tsim qauv thiab daim ntawv
ASTM A106:
• Txheej txheem: tsuas yog tsis ncaj ncees tsim khoom (kub yob lossis cov duab txias lossis txias), kom tsis muaj cov ntsiab lus tsis muaj zog hauv Weld Seam nyob rau hauv lub kub thiab siab siab.
• Daim Ntawv: Tsuas yog ncig ncig - seem.
ASTM A500:
• Cov txheej txheem: Txhawb cov vuam lossis seamless vuam, thiab yuav tsum tau txias ua rau txhim kho lub zog.
• Daim Ntawv: Nws tau them ntau tus hla -} ntu xws li vas, xwmfab, thiab duab plaub, yoog raws li cov qauv sib txawv.
4. Siv tau ib puag ncig thiab cov cai tshwj xeeb
ASTM A106:
• Thaum kub tsis kam: nws tuaj yeem tiv taus ntev}}}}}} kev ntsuas siab dua lossis muaj kev sib npaug- kub tensile xeem.
• Yuav kuaj cov kev xeem: Yuam kev ua haujlwm hydrostatic kuaj thiab tsis - kev sim (xws li ultrasonic kuaj) kom paub tseeb.
ASTM A500:
• Kev hloov kho ib puag ncig: haum rau cov qauv zoo li qub ntawm ib txwm lossis tsawg kub, uas tsis muaj siab - kub ua tau zoo.
• Kev tshuaj xyuas: Qhov seem tsis ntev (cov uas hla ± 1%, phab ntsa thickness - 10%), chaw nyob tiaj.
5. Cov qauv txheej txheem thiab qib kawm qib kawm
| Lub hom phiaj | Teem nqi | Raug Daim Ntawv Teev Lus |
| ASTM A106 | A, B, C | B Qib yog qhov feem ntau (siab - kub kav) |
| ASTM A500 | A, B, C, D | B (General qauv), C / D Qib (txhawb nqa hnyav) |
Ntsiab lus: Cov kev sib txawv thiab xaiv cov lus qhia
Qhov tseem ceeb txawv:
ASTM A106 yog tus qauv rau cov kav dej tsis zoo, tsom mus rau siab- kub sefting thiab siab tsis kam. ASTM A500 yog tus qauv rau kev teeb tsa hlab, hais txog load -}} kev siv duab lub zog.
Xaiv Scenario:
• Xaiv A106: High - dej khov, roj thiab roj tsheb thauj mus los, thiab hwj huam raj hluav taws xob tshuab.
• Xaiv A500: cov qauv zoo li qub xws li lub tsev kawm ntawv ua ke, thiab cov chaw tsheb.
• Tsis -} kev hloov pauv tau: vim muaj cov hom phiaj tsim thiab kev ua tau zoo, ob qho chaw tsis tuaj yeem hloov dua.
Rau kev sib piv ntxiv ntawm cov tsis muaj zog (xws li loj npaum li cas thiab cuam tshuam cov ntawv nyeem), cov thawj cov ntawv ntawm Astm A106-19 tus qauv lossis lub tshuab ua tshuab tau raug xa mus.
