Cov ntsiab lus ceev
1.0425yog cov ntaub ntawv tsim raws li GermanDIN 17100Txheem rau cov hlau. Nws yog atsis -} alloy, siab - zoo carbon steelpaub rau nws lub zog zoo thiab muaj sia. Nyob rau hauv cov ntsiab lus ntawm cov kav dej, ib "1.0425 seamless steel yeeb nkab" yog lub raj tsim tawm yam tsis muaj kev tshwj xeeb ntawm cov hlau, ua rau nws zoo tagnrho rau cov ntawv thov siab.
Qhov kev lees paub thiab thoob ntiaj teb lees paub sib npaugASTM A106 Qib B.
1. Cov khoom siv tshwj xeeb thiab sib npaug
| Lub hom phiaj | Teem nqi | Qhov tseem ceeb |
|---|---|---|
| DIN 17100 | 1.0425(ST 52.0) | Tus thawj qauv German. |
| ASTM A106 | Qib B | Cov txheej txheem thoob ntiaj teb feem ntau rau kev kub siab - kub seamless cov yeeb nkab roj. |
| En 10255 | -- | Tsis yog qib ncaj qha, tab sis cov kav dej tuaj yeem muab rau cov qauv no. |
| DIN 2448 | -- | Ib qho kev ua yeeb yam German rau sab hauv kev ua siab ntev ntawm cov kav dej seamless. |
Nco tseg rau "St 52.0":Koj yuav pom cov ntawv txheej txheem qub no. "St" sawv ntsug rau "Stahl" (hlau), "52" qhia txog tsawg zog lub zog ntawm 52 kgf / mpa} mpa mpa}
2. Tshuaj lom neeg sib xyaw ua ke (raug))
Cov muaj pes tsawg leeg yog sib npaug rau Weldability, lub zog, thiab muaj peev xwm.
| Lub ntsiab | Carbon (c) | Manganese (mn) | Phosphorus (p) | Sulphur (s) | Silicon (si) |
|---|---|---|---|---|---|
| Zoo siab | Tsawg dua los yog sib npaug rau 0.22% | 1.00 - 1.60% | Tsawg dua los yog sib npaug rau 0.025% | Tsawg dua los yog sib npaug rau 0.025% | Tsawg dua los yog sib npaug rau 0.55% |
Cov pa roj carbon tsawg:Ua rau nws yooj yim weldable.
Manganese:Nce lub zog thiab tawv tawv.
Tsawg P & S:Txhim kho cov kev coj dawb huv thiab txhim kho kev ua kom muaj weldability thiab tiv taus kom tawg.
3. Cov Khoom Siv Kho Tshuab
Cov khoom no ua rau nws muaj zog dua li cov hlau me (zoo li st37 lossis a106 gr. A).
| Ntiag tug | Tus nqi | Yam tseem ceeb |
|---|---|---|
| Yield zog (min) | 355 MPa(51,500 psi) | Feem ntau hauv cov xwm txheej li qub |
| Lub zog tensile | 510 - 650 mpa(74, 000 - 94}, 300 psi) | Feem ntau hauv cov xwm txheej li qub |
| Elongation (min) | ~21% | Sib txawv nrog gauge ntev |
4. Cov yam ntxwv tseem ceeb & Cov txiaj ntsig
Seamless kev tsim kho:
Tsis muaj Welded Seam:Tshem tawm cov peev xwm muaj peev xwm taw tes pom nyob hauv welded (ERW) kav dej.
Lub zog hnav zoo li:Muaj cov khoom siv kho txhua yam nyob ib ncig ntawm nws txoj kev ncig.
Kev kub siab kuj:Thawj qhov laj thawj rau xaiv seamless kav hla welded sawv daws.
Zoo xws li muaj zog:Nws txoj kev ua tiav (zoo ib yam li A106 Gr. B) yog qib ua haujlwm rau ntau cov ntawv thov siab.
Zoo heev Weldability:Vim yog nws cov ntsiab lus carbon ntau, nws tuaj yeem muab tso tawm yooj yim siv tag nrho cov kev tsis muaj ua ntej tshaj plaws (rau kev kho cua sov.
Zoo machinability thiab formability:Nws tuaj yeem khoov duav, flanged, thiab machined yooj yim.
Tus nqi -} Siv tau ua haujlwm:Muaj kev sib npaug zoo ntawm lub zog, durability, thiab tus nqi rau tsis {{0} {corrosive daim ntaub ntawv.
5. Cov Ntawv Thov Tib Neeg
1.0425 Seamless kav yog siv txhua qhov chaw siab lub zog thiab lub zog muaj zog yog xav tau.
Lub zog tiam:Tube thoiles, cov kab tsheb superas, thiab chav dej hauv pob txha pob zeb roj teeb.
Roj & Roj:
Txheej txheem Piping hauv kev ua kom zoo thiab cov nroj tsuag petrochemical.
Cov kab kis tau cov kab rau cov roj thiab roj (onshore thiab sab nrauv).
Nplua thiab cov txheej txheem piping.
Neeg kho tshuab thiab cov txheej txheem engineering:
High - lub siab hydraulic thiab pneumatic.
Raj raj leeg.
Thauj {- Cov kabmob qauv qauv uas yuav tsum muaj tubular tshooj.
Kev Tsim Kho:Txog siab -} cov tshuab hluav taws xob hauv vaj tse loj thiab muaj chaw muaj kev lag luam.
6. Cov kev txiav txim siab tseem ceeb
Corrosion Kuj:1.0425 yog cov pa roj carbon hlau thiabtsis yog corrosion - tsis kamCov. Nws yuav xeb yog tias raug dej thiab huab cua. Txog kev xeb ib puag ncig, nws yuav tsum muaj kev tiv thaiv nrog cov txheej txheem, xim, lossis cov ntaub pua chaw (piv txwv li, 1.440 / 316L) yuav tsum tau siv.
Txwv ntsuas kub:Thaum nws ua tau zoo ntawm cov chaw kub siab, nws qhov kev siv feem ntau yog txwv rau cov kev pabcuam kom txog~ 450 Qib (842 Qib F)Cov. Rau qhov siab dua, cov hlau nplaum ntau dua.
Cov Qauv thiab Kev Ntsuam Xyuas:Nco ntsoov xyuas kom cov yeeb nkab tau muab cov ntawv pov thawj zeb xeem (MTC)
