Tshaj tawm ntau dhau
Mas siv nyob rau hauv offshore roj thiab roj, tshuaj, roj av thiab petrochemical industries nyob rau hauv lub pipeline system, ntws kab vuam ntawm riser, sau yeeb nkab, thiab lwm yam.
Haum rau vuam ntawm duplex stainless hlau uas muaj 25% Cr,
xws li 00 cr25ni7mo4n, 03 cr25ni6mo3cu2n, UNS 32550 (Alloy255), thiab lwm yam.
Ripple zoo
Tsawg hydrogen super duplex stainless hlau tes electrode, lub ntsiab muaj pes tsawg leeg yog 25Cr-9.5Ni-3.4Mo-2.5Cu-0.2N
Cov hlau weld yog austenitic thiab ferritic biphase qauv, thiab corrosion kuj Performance index yog PRE> 40. Nws muaj lub zog siab thiab ua haujlwm zoo rau pitting thiab kev nyuaj siab corrosion cracking. Cov tshuab vuam zoo heev, ruaj khov arc, zoo nkauj tsim, muag muag ripple, me ntsis txaws, yooj yim slag tshem tawm.
Yooj yim slagging
