Khoom Description
Peb lub siab -siab seamless alloy steel kav yog tsim tshwj xeeb rau boiler tseem ceeb thiab kev siv kav dej. Tsim nyob rau hauv nruj raws li ASTM A335 / ASME SA335 tus qauv, npog mainstream chrome-molybdenum qib suav nrog P11, P22, thiab P91 . Lub SCH40 thiab SCH80 phab ntsa thickness teem precisely phim sib txawv ntawm cov kev ntsuas siab, ua rau lawv zoo tagnrho rau cov kab hluav taws xob hluav taws xob, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob loj siab -kub / siab - cov txheej txheem piping, thiab cov khoom siv hluav taws xob.
Core Zoo
Seamless Structure – Zero Weld Weak Points
Tsim los ntawm kev kub extrusion + precision txias- cov txheej txheem dov, cov yeeb nkab nta ib qho kev sib txuas tag nrho- lub cev dawb, tshem tawm cov kev pheej hmoo ntawm cov weld tsis xws luag thiab ua kom muaj kev ruaj ntseg zoo tshaj plaws nyob rau hauv siab - kub cyclic loading .
Alloy Steel Composition - Siab -Tsub & Creep Resistance
Qhov optimized piv ntawm Chromium (Cr) thiab Molybdenum (Mo) muab tshwj xeeb siab -kub kev ua haujlwm:
Molybdenum: Txhim kho siab - kub lub zog, nkag siab tsis kam, inhibits grain loj hlob, thiab txo embrittlement kev pheej hmoo
Chromium: Muab oxidation tsis kam ntawm qhov kub thiab txias, ncua kev pab cuam lub neej nyob rau hauv 540-750℃ib puag ncig
Tag Nrho Cov Qauv Ua Raws Li Txoj Cai Zoo
Tsim los rau ASTM A335 / ASME SA335 cov lus qhia tshwj xeeb, nrog cov qib siv feem ntau suav nrog P5, P9, P11, P22, thiab P91 . Txhua yeeb nkab tuaj nrog:
Mill Test Certificate (MTC)
Chemical composition & mechanical properties reports
Tsis yog-cov ntawv ceeb toom kev ntsuas kev puas tsuaj (UT + ET)
Daim ntawv qhia txog Hydrostatic Test
Kev them nyiaj yug rau - tog thib peb kev soj ntsuam thiab kev lees txais qhov project
