Lub hauv paus rau phau ntawv
- ASTM A53yog tus qauv tshwj xeeb los ntawm covAmerican Society rau Kev Ntsuam Xyuas thiab Khoom (ASTM)npogseamless thiab welded carbon steel kavnrog nominal ntsa tuab. Nws yog dav siv rauCov ntawv thov txheej txheem, kav dej, thiab cov kua muag kom tsawg.
- Qib Byog cov qhab nia feem ntau nyob hauv cov qauv no, muabNtau Dua Lub Zog thiab Tshaj Tawm Lub ZogPiv rau qib A, ua rau nws haum rau cov ntawv thov ntau dua.
| Qhov loj me (hli) | 1\/2 nti - 24 nti |
| Phab Ntsa Thickness (Mm) | 1.2 - 22 |
| Ntev (m) | Nquag 6m \/ 12m, kuj yog nyob ntawm qhov yuav tsum tau ua |
Cov txheej txheem tsim khoom
ASTM A53 Gr. B kav yog muaj nyob rau hauvob hom:
- Hom E (hluav taws xob tiv thaiv welded - ERW)
Tsim los ntawm dov hlau coils rau hauv ib lub cylindrical puab thiab vuam lub seam.
Raug nqi - ua tau zoo tab sis muaj cov kab weld pom.
- Hom S (Seamless)
Tsim los ntawm tho cov khoom noj khoom haus hnab nyiaj, ua rauTsis muaj Welded Seam.
Zoo dua rauKev Siv SiabVim muaj lub zog ntawm lub zog.
Tshuaj lom neeg muaj pes tsawg leeg thiab cov khoom siv neeg kho tshuab
Tshuaj Muaj Tshuaj
ASTM A53 Qib B Yeeb Nkab muaj cov tshuaj lom neeg tshwj xeeb uas ua kom nws cov khoom siv neeg kho mob tshwj xeeb.
| Lub ntsiab | Muaj pes tsawg leeg (%) |
|---|---|
| Carbon (c) | Tsawg dua los yog sib npaug rau 0. 30% |
| Manganese (mn) | Tsawg dua los yog sib npaug rau 1.20% |
| Phosphorus (p) | Tsawg dua li lossis sib npaug rau 0. 05% |
| Sulphur (s) | Tsawg dua los yog sib npaug rau 0. 045% |
| Hlau (FE) | Seem |
- Cov ntsiab lus muaj roj carbon tsawgkom ntseeg tau zooWeldability thiab Formability.
- Ntau dua manganesetxhim kho lub zog thiab hardness.
- Lwm cov ntsiab lus xws liSulphur thiab phosphorusyogkhaws cia tsawg kawg nkauskom tsis txhob brittleness thiab kom cov yeeb nkab lub durability.
Cov Khoom Siv Neeg Kho Tshuab
| Ntiag tug | Qib B Yuav tsum muaj |
|---|---|
| Lub zog tensile | Ntau dua los yog sib npaug rau 415 MPa (60,200 psi) |
| Paib lub zog | Ntau dua los yog sib npaug rau 240 MPa (35, {2}} psi) |
| Elongation (%) | Ntau dua los yog sib npaug rau 23% (ntev) |
- Lub zog siab duaTshaj li qib A (qib ib lub tensile: ntau dua lossis sib npaug ntawm 330 MPa).
- Haum rauKev Siv Siab-Cov Kab Mob(xws li, chav dej, dej, roj).
Cov ntawv thov thiab cov txiaj ntsig
Cov Kev Siv Cov Ntawv Siv
ASTM A53 qib qib B Kave yog siv nyob rau ntau yam kev lag luam vim lawv lub zog thiab lub zog. Zoo li:
- Kiv dej & khoom siv dej:Dej faib khoom, siv cov dej ua paug.
- Roj & Roj:Kev thauj khoom ntawm cov roj nyoos, cov nkev roj (cov kab qis qis).
- Cov qauv siv:Lub tuam tsev thav ntawv, scaffolding, xuas tes ua.
- HVAC tshuab:Devwork, Chav Rau Chav.
- Kev Tiv Thaiv Hluav Taws Kub:Sprinkler raj.
Qhov zoo ntawm Astm A53 Gr. B
- Siab zog-rau-qhov hnyav piv- muaj zog tsis tau lub teeb.
- Zoo Weldability & Machinability- Yooj yim rau ntaub.
- Nqi-Zoo- Tus pheej yig dua cov hlau hlau lossis cov kav dej nkaus.
- Versatility- Siv rau hauv ob qho qauv txheej txheem thiab kev siv siab.
