Xaiv qhov raugalloy steel yeeb nkabyog qhov tseem ceeb rau kev ua haujlwm, kev nyab xeeb, thiab kev siv nyiaj txiag. Nrog rau ntau qib, cov qauv, thiab cov txheej txheem tsim khoom, cov neeg yuav khoom xav tau lub ntsiab lus meej. Phau ntawv qhia no suav nrog cov ntsiab lus tseem ceeb rau xyoo 2026.
1. Txhais cov kev ua haujlwm
Pib nrog koj ib puag ncig:
- KubQhov kub thiab txias (tsawg dua lossis sib npaug rau -40 degree), nruab nrab (350-550 degree), siab kub (550-650 degree)
- Siab: Tsawg, nruab nrab, siab (Ntau dua lossis sib npaug rau 100 bar)
- Nruab nrab: Dej, chav dej, roj, roj, H2S, acid, alkali, chloride
- Cyclic loads: qaug zog thiab kev co kuj
2. Xaiv qhov raug Alloy qib
Cov qhab-nees thiab kev siv ib txwm:
- Tsawg- alloy (1-5% Cr): 16Mn, 15CrMo, 12Cr1Mo - dav dav qhov siab
- Nruab nrab- alloy (5-12% Cr): P91, P92, T91 - ultra-supercritical boilers
- Stainless & siab{0}} alloy: 304, 316L, 2205, 310S - corrosion{5}}cov kev pabcuam tiv taus
- Nickel -raws li: Alloy 600, 625, 825 - huab cua corrosion/kub
3. Txheeb xyuas cov qauv & ua raws
Xyuas kom cov kav dej ua tau raws li cov qauv thoob ntiaj teb:
- ASTM / ASME CovQauv: A335, A213, A106, SA106
- API: 5CT (roj zoo), 5L (kab yeeb nkab)
- DIN, EN, GB
- Yuav tsum tau xeem:UT, ET, HT, PMI, tensile, cuam tshuam, hardness
4. Cov txheej txheem ntau lawm
- Seamless vs. welded: Seamless nyiam rau kev kub siab / kub
- Kub-ua tiav / txias- kos: Txias-kos tau zoo dua precision thiab nto tiav
- Kev kho cua sov: Normalized, quenched, tempered - tseem ceeb rau creep zog
5. Tshawb xyuas cov ntaub ntawv zoo
Cov neeg muag khoom ntseeg tau muab:
- Material Test Report (MTR)
- Mill test daim ntawv pov thawj (TS EN 10204-3.1)
- NDT reports
- Thaum tshav kub kub tooj thiab ntau traceability
6. Koom tes nrog ib tus neeg muaj kev paub dhau los
Nrhiav:
- Export daim ntawv tso cai (2026 raws)
- Hauv -lub tsev kuaj thiab kuaj muaj peev xwm
- Kev cai loj / qib ntau lawm
- ruaj khov raw khoom muab
- Ntawm -lub sij hawm logistics thiab kev lis kev cai txhawb nqa
Cov Lus Qhia Kawg
Tsis txhob xaiv raws li tus nqi xwb.Tsawg- cov kav dej raug nqi feem ntau ua tsis tiav hauv cov xwm txheej tseem ceeb, ua rau cov nqi ntev dua - lub sij hawm. Ua ntejzoo, ntawv pov thawj, thiab traceability.
