A/SA106 Pipe yog dab tsi?
A/SA106 yog tus qauv specification rau seamless carbon steel yeeb nkab npaj rau siab - kub kev pab cuam. ASTM version yog xaiv A106 thiab ASME version SA106; ob cov ntaub ntawv yog technically zoo tib yam. Cov yeeb nkab yog siv rau hauv cov roj thiab roj refineries, fais fab nroj tsuag, petrochemical nroj tsuag, boilers, thiab ships qhov twg cov kav dej yuav tsum thauj cov kua thiab gases ntawm siab kub thiab siab. Nws yog qhov tsim nyog rau kev khoov, flanging, thiab kev ua haujlwm zoo sib xws.
Qib A106
Tus qauv txhais tau peb qib zog.
| Qib | Yam tsawg kawg Yield Strength | Yam tsawg kawg Tensile Strength |
|---|---|---|
| Qib A | 30 ksi, sib npaug rau 205 MPa | 48 ksi, sib npaug rau 330 MPa |
| Qib B | 35 ksi, sib npaug rau 240 MPa | 60 ksi, sib npaug rau 415 MPa |
| Qib C | 40 ksi, sib npaug rau 275 MPa | 70 ksi, sib npaug rau 485 MPa |
Qib B yog qib kev txiav txim siab tshaj plaws, thaum Qib C raug xaiv thaum xav tau lub zog ntau dua rau qhov loj thiab phab ntsa tuab.
Tshuaj muaj pes tsawg leeg
| Lub ntsiab | Qib A | Qib B | Qib C |
|---|---|---|---|
| Carbon, C, siab tshaj | 0.25% | 0.30% | 0.35% |
| Manganese, Mn | 0.27% rau 0.93% | 0.29% rau 1.06% | 0.29% rau 1.06% |
| Phosphorus, P, max | 0.035% | 0.035% | 0.035% |
| Sulfur, S, siab tshaj | 0.035% | 0.035% | 0.035% |
| Silicon, Si, yam tsawg kawg nkaus | 0.10% | 0.10% | 0.10% |
Kev tsim khoom
Cov yeeb nkab yog tsim los ntawm cov hlau tua, melted los ntawm qhib -hearth, yooj yim- oxygen, los yog hluav taws xob- cov txheej txheem rauv, tejzaum nws ua ke nrog cais degassing lossis refining. Cov hlau yuav raug muab pov rau hauv cov khoom siv los yog cov hlua khi. Cov yeeb nkab ntawm NPS 1-1 / 2 thiab me me tuaj yeem ua tiav kub lossis txias, thaum cov yeeb nkab ntawm NPS 2 thiab loj dua yog kub tiav tshwj tsis yog tau teev tseg. Cov yeeb nkab kub tiav tsis tas yuav tsum tau kho cua sov, thaum cov yeeb nkab txias txias yuav tsum tau kho cua sov tom qab qhov kawg txias kos dhau.
Qhov Loj Loj thiab Teem caij
A106 yeeb nkab feem ntau muab nkag rau hauv NPS 1/4 rau NPS 36 sab nraud txoj kab uas hla, nrog phab ntsa thicknesses los ntawm Teem caij 20 txog Teem caij XXH thiab hnyav dua. Phab ntsa thicknesses txog li 140 mm yog muaj los ntawm loj - txoj kab uas hla manufacturers. Tus txheej txheem npog nominal phab ntsa yeeb nkab, thiab qhov ntev kam rau ua raws li cov yeeb nkab loj rooj.
Kev kuaj thiab tshuaj xyuas
Txhua cov yeeb nkab yog kuaj hydrostatically txhawm rau txheeb xyuas qhov tseeb siab. Tsis yog-kev kuaj hluav taws xob puas xws li eddy tam sim no lossis kuaj ultrasonic tuaj yeem raug teev los ntawm tus neeg yuav khoom kom pom qhov tsis zoo. Cov khoom siv kho tshuab raug txheeb xyuas los ntawm kev ntsuas tensile, thiab cov tshuaj muaj pes tsawg leeg los ntawm kev ntsuas cua sov. Mill daim ntawv pov thawj sau cov txiaj ntsig thiab yuav tsum muaj rau cov ntaub ntawv pov thawj siab.
Tej kev siv
A106 yeeb nkab yog siv rau siab -kub chav kab, boiler feed kab, refinery txheej txheem piping, thiab fais fab nroj tsuag piping. Nws nqa cov kua dej kub thiab cov roj cua uas qhov ntsuas kub thiab siab tshaj qhov txwv ntawm qis - kub lossis dav - lub hom phiaj specifications. Nws kuj tseem siv rau cov tswv cuab hauv cov khoom siv hauv siab - qhov kev pabcuam kub, xws li kev txhawb nqa thiab pawg.
FAQ
Dab tsi yog qhov txawv ntawm ASTM A106 thiab ASME SA106?
Lawv yog tib yam specification uas tau muab los ntawm ob lub koom haum. ASTM luam tawm A106 thiab ASME luam tawm SA106 rau kev siv hauv ASME-cov qauv tsim. Cov kev cai yuav tsum yog tib yam, thiab ob qho kev xaiv yuav tshwm sim ntawm daim ntawv pov thawj.
Qhov twg qib A106 feem ntau?
Qib B yog qib feem ntau xaj. Nws muaj qhov sib npaug zoo tshaj plaws ntawm lub zog, muaj, thiab tus nqi rau feem ntau ntawm -kub siab piping daim ntawv thov.
Puas yog A106 yeeb nkab welded lossis seamless?
A106 npog seamless yeeb nkab nkaus xwb. Rau welded yeeb nkab hauv kev pabcuam zoo sib xws, cov qauv xws li A671 lossis A691 yog siv nyob ntawm qhov ntsuas kub thiab siab.
Qhov tua steel txhais li cas?

Qhov siab tshaj plaws ua haujlwm kub rau A106 Qib B yog dab tsi?
Qhov kub siab tshaj plaws nyob ntawm tus qauv tsim. Raws li ASME B31.3 thiab B31.1, Qib B feem ntau txwv rau li 425 degrees Celsius, dhau ntawm cov khoom nkag tau tswj hwm tus qauv tsim.
Yuav ua li cas kev ntsuam xyuas ntawm txhua lub yeeb nkab?
Txhua cov yeeb nkab yog kuaj hydrostatically. Cov kev xav tau ntxiv xws li tsis yog -kev ntsuas hluav taws xob puas tsuaj, kev sib tsoo, lossis kev sim cuam tshuam tau teev tseg los ntawm tus neeg yuav khoom thaum qhov kev pabcuam xav tau.
