1. Cov qauv GB / T 3094 thiab ASTM A213 txhais li cas rau cov kav dej no?
Teb:
GB / T 3094 yog Suav lub teb chaws tus qauv qhia qhov txias-draw precision steel hlab (xws li carbon thiab alloy steel) nrog nruj tolerances thiab zoo nto tiav; feem ntau siv rau machining, structural thiab dej kev pab cuam.
ASTM A213 / ASME SA213 yog tus qauv Asmeskas rau seamless ferritic thiab austenitic alloy steel boiler, superheater, thiab cua kub-exchanger raj, npog cov qib xws li npib tsib xee alloys xws li Inconel thiab high-temperature steels.
Ob leeg ua kom zoo ib yam zoo, tshuaj muaj pes tsawg leeg, cov khoom siv kho tshuab, thiab cov kev sim rau kev siv hauv kev lag luam.
2. Dab tsi yog cov yam ntxwv ntawm cov nickel alloys teev (Inconel 600, 601, 625, 718, 725, 926, X-750)?
Teb:
Cov nickel-based superalloys txhua tus muaj cov yam ntxwv ua tau zoo:
Inconel 600 & 601: Zoo heev oxidation thiab corrosion kuj, zoo-kub lub zog.
Inconel 625: Superior corrosion kuj thiab lub zog tshaj qhov kub thiab txias; dav siv nyob rau hauv chemical thiab marine ib puag ncig.
Inconel 718: Siab creep, qaug zog, thiab kev ntxhov siab-rupture tsis kam mus txog ~ 700 degree.
Inconel 725, 926, X-750: Advanced alloys nrog txhim khu lub zog, corrosion kuj, thiab thermal stability rau xav tau aerospace thiab lub zog tsim siv.
3. Dab tsi yog qhov txiaj ntsig ntawm qhov txias dov hauv kev tsim cov kav dej seamless?
Teb:
Cov txheej txheem txias dov txo lub raj txoj kab uas hla thiab phab ntsa tuab ntawm chav tsev kub, ua rau:
Txhim kho phab ntsa thickness uniformity thiab nruj dua tolerance piv nrog cov kav kub-dov.
Smooder nto tiav thiab zoo dua dimensional precision.
Txhim kho cov yam ntxwv zoo tsim nyog rau kev tsim khoom precision, kev pabcuam siab, thiab kev siv high-engineering.
4. Cov ntawv thov twg yog cov hlau alloy thiab cov nickel alloy seamless kav siv rau?
Teb:
Cov kav dej no yog siv rau qhov chaw muaj zog, tiv thaiv corrosion, kub ua hauj, los yog precision yuav tsum tau, xws li:
Boilers, heat exchangers, thiab superheaters hauv fais fab nroj tsuag (ASTM A213 kev pabcuam).
Kev ua tshuaj lom neeg, petrochemical, offshore, thiab marine systems tuav cov kua dej corrosive.
Aerospace thiab high-temperature industrial daim ntaub ntawv yuav tsum tau ruaj khov mechanical zog.
Tus qauv thiab precision kua conveyance nyob rau hauv manufacturing thiab machinery (txias-rolled steel).
5. Cov neeg yuav khoom yuav ntsuas qhov zoo thiab xaiv cov khoom siv yeeb nkab li cas?
Teb:
Cov yam tseem ceeb muaj xws li:
Kev ua raws li tus qauv: Xyuas kom cov kav dej ua tau raws li cov qauv ASTM / ASME / GB / T nrog cov ntaub ntawv tiav thiab daim ntawv pov thawj zeb xeem (MTC).
Cov ntaub ntawv qib vs daim ntawv thov: Xaiv cov alloy raws li qhov kub thiab txias, siab, thiab corrosive tej yam kev mob
Surface and dimension tolerances: Cold-rolled pipes muab precision thiab smoother nto, uas yuav muaj teeb meem nyob rau hauv high-end fabrication.
Kev tshuaj xyuas & kev sim: Nrhiav cov kev ntsuam xyuas hydrostatic / NDT thiab cov ntaub ntawv tshuaj xyuas thib peb rau kev ntseeg siab rau kev pabcuam tseem ceeb.
