Ntau lub ntiaj teb engineering buyers ntsib tib qhov teeb meem kim:alloy steel kav hla lub Hoobkas tshuaj xyuas, tab sis ua tsis tiav tom qab luv - lub sijhawm ua haujlwm ntawm qhov chaw. Cov teeb meem tshwm sim muaj xws li tawg nyob rau hauv qhov kub thiab txias, leakage nyob rau hauv siab siab, nto corrosion, thiab lub neej luv luv. Cov kev ua tsis tiav no ua rau muaj kev kaw haujlwm, cov nqi kho mob, thiab txawm tias muaj xwm txheej nyab xeeb.
Feem ntau cov yeeb nkab tsis ua haujlwm tsis yog los ntawm kev ua haujlwm tsis raug, tab sis los ntawmKev xaiv qib tsis raug, kev kho cua sov tsis tsim nyog, thiab kev xeem NDT tsis tiav. Hauv phau ntawv qhia no, peb sau cov lus qhia txog rau feem ntau ntawm cov hlau yeeb nkab tsis ua haujlwm thiab cov kev daws teeb meem los pab cov neeg yuav khoom thoob ntiaj teb kom tsis txhob poob qhov project loj.
1. Siab -Tsub Cracking (Common rau P91/P92/T91)
Failure Phenomenon: Cov yeeb nkab lub cev lossis vuam tawg tom qab ntev - lub sijhawm ua haujlwm siab tshaj 550℃.
Keeb kwm: Kev kho tsis zoo quenching thiab tempering, tsis ruaj khov creep zog, tsis tsim nyog chromium -molybdenum element ratio.
Kev daws: Xaiv cov kav dej nrognruj Secondary kev kho cua sovthiab ua kom tiav creep zog xeem ntawv ceeb toom. Rau ultra-supercritical fais fab nroj tsuag, tsuas yog siv tus qauv P91/P92 alloy kav nrog daim ntawv pov thawj MTR tag nrho.
2. Siab -Npaum Leakage (Boiler & Chav Pipeline)
Failure Phenomenon: Micro- leakage ntawm cov yeeb nkab lub cev los yog weld seam nyob rau hauv siab nruam siab.
Keeb kwm: Internal porosity, me me inclusions, unqualified phab ntsa thickness kam rau ua, uas ploj lawm UT ultrasonic kuaj.
Kev daws: Xav tau cov neeg muab khoom los muab100%., tsis lees paub qhov kev tshuaj ntsuam random.
3. Ntsig Gas Corrosion Failure (Oil & Gas Well)
Failure Phenomenon: Pitting corrosion thiab sulfide kev ntxhov siab tawg hauv H2S & CO2 ib puag ncig.
Keeb kwm: Siv cov yeeb nkab uas tsis tshua muaj -cov kav hlau tsis muaj CRA corrosion- cov kav hlau tsis muaj zog.
Kev daws: Xaiv 22Cr/25Cr duplex stainless hlau los yog customized anti-cov kav dej qaub rau cov dej sib sib zog nqus.
4. Hydrogen Embrittlement Failure (Hydrogen Energy Project)
Failure Phenomenon: Cov yeeb nkab brittleness thiab tawg nyob rau hauv siab -siab hydrogen kis tau tus mob.
Keeb kwm: Ordinary alloy kav tsis tuaj yeem tiv thaiv hydrogen molecule nkag mus.
Kev daws: Txaishydrogen embrittlement resistant customized alloy kavnrog tshwj xeeb qis-carbon formula.
5. Dimensional Tolerance yuam kev (Installation Mismatch)
Failure Phenomenon: Cov kav dej tsis tuaj yeem phim cov flanges thiab fittings, ua rau raug yuam kev teeb tsa thiab tom qab xau.
Keeb kwm: Tsawg-precision kub dov ntau lawm, tsis tsim nyog OD / ID kam rau ua.
Kev daws: Xaiv txias - kos precision alloy kav nrog kam rau ua nyob rau hauv ± 0.05mm.
6. Lub neej luv luv vim cov khoom tsis ruaj khov
Failure Phenomenon: Ib puag ncig kev ua haujlwm zoo tab sis kev laus sai thiab oxidation.
Keeb kwm: Recycled scrap steel raw khoom, cov ntsiab lus tsis ruaj khov alloy.
Kev daws: Koom tes nrog cov neeg siv khoom siv100% tshiab raw khoomthiab muab cov xov tooj cua sov traceability rau txhua pawg.
