Ib 691 1} cr alloy steel yeeb nkab piav qhia
A 691 1}} welded yeeb nkab yog ib qho chromium-molybdenum}}}}}}}}
Cov qib yog cim raws li 691 1 cr cl21 ("CL21" sawv cev rau cov khoom siv qib).
Cov txheej txheem tsim khoom
Hluav taws xob fusion vuam (EFW) cov txheej txheem tau saws, thiab Weld tau kho nrog kom ntseeg tau cov qauv txheej txheem kev cai.
Tom qab vuam, li qub + tempering kev kho cua sov yuav tsum tau nqa tawm kom tshem tawm sab hauv kev ntxhov siab thiab ua kom zoo ntawm daim hlau ntsuas.

Qhov Zoo
- Kev kub siab: ua haujlwm kub tsawg dua lossis sib npaug nrog 550 degree, lub zog luv, zoo tawm lub zog loj dua los yog sib npaug rau 205mpa)
- Economical: Piv nrog cov roj chromium siab (xws li 3cr, 5cr), tus nqi yog txo los ntawm kwv yees li 20% {%, haum rau cov phiaj xwm siv nyiaj txiag
- Corrosion Kuj: Chromium Cov Zaj Duab Zaj Duab Uas tuaj yeem tiv thaiv corrosion hauv acidic acidic media (xws li sulphur-muaj flue roj, muaj chav)
- Cov txheej txheem ntseeg tau: 100% Kev Ntsuas Hluav Taws Xob (RT) thiab Ultrasonic Kev Ntsuas (U) ntawm ntau dua 95% ntawm niam txiv cov khoom
Cov Ntawv Thov
- Cov Khoom Hluav Taws Xob: Subcritical Boiler Roj Hlau Phom Roj Txhuas Roj Txhuas, Econolizing Manaufold
- Petrochemical: Tsawg-Kub Roj Khoom Pipeline, Cov Khoom Siv Hluav Taws Xob Siab Lub Siab Ua Si Cov Khoom Siv Hluav Taws Xob (Kub tsawg dua lossis sib npaug)
- Kev Lag Luam Machinery: Lub Tshuab Kho Mob Hydraulic Tes Tsho
