Super Duplex 2507 yeeb nkab muaj PREN Ntau dua lossis sib npaug li 42 thiab CPT (qhov tseem ceeb pitting kub) ≈ ntawm 85 degree, ua rau nws tiv taus corrosion los ntawm siab - dej hiav txwv kub, concentrated brine (20% NaCl), sib sib zog nqus - hiav txwv / offshore splash zones, thiab acidic brines.
Qhov tsawg kawg nkaus lub zog ntawm 2507 yog siab li 550 MPa (80 ksi), kwv yees li peb npaug ntawm 316L thiab ntau dua li cov qauv duplex steel 2205 (Ntau dua lossis sib npaug rau 450 MPa), tso cai rau nyias nyias- cov qauv tsim phab ntsa thiab txo cov nqi khoom.
Super duplex stainless hlau 2507 nthuav tawm txo qhov toughness thiab corrosion kuj ntawm kub kub; Yog li ntawd, qhov pom zoo ua haujlwm kub tsis siab tshaj 316℃(600℃F). Qhov tsawg kawg nkaus ua haujlwm kub tuaj yeem ncav cuag -50 degree.
Customized Services
- TORICH muaj kev hloov kho rau qhov tsis yog - qhov loj me, npog sab nraud ntawm 6mm-630mm, phab ntsa thicknesses ntawm 0.5mm-55mm, thiab ntev li ntawm 3 mus rau 12 meters.
- Xaus- cov kev pabcuam ua haujlwm muaj, suav nrog tus qauv lossis tshwj xeeb beveling (V-type, U-type, ob npaug-V), threading (NPT, BSP, API), thiab prefabricated flange vuam.
- Ntxiv rau cov txheej txheem pickling, kev kho deg xws li electropolishing (Ra Tsawg dua lossis sib npaug li 0.4μm), ci ntsa iab, sandblasting, thiab sab hauv honing muaj.

Cov qhab nia xaiv tau
- Rau ntau cov roj thiab roj qhov dej, desulfurization units, thiab acid pickling systems, Zeron 100 (UNS S32760) yog ib qho kev xaiv; nws muaj superior corrosion kuj, tab sis tus nqi yog kwv yees li 15-25% siab dua li ntawm 2507.
- Rau kev sib sau thiab xa cov kav dej nrog qis acidity thiab tsis muaj H₂S cov ntsiab lus, 2205 yog qhov kev xaiv tsim nyog; nws tsis tshua kim tshaj 2507 thiab yooj yim rau fabricate thiab weld.
- Rau cov ntawv thov uas xav tau kev tiv thaiv corrosion siab tab sis tsuas yog lub zog nruab nrab, 254SMO lossis 904L tuaj yeem raug xaiv, vim lawv tiv taus qhov kub thiab txias siab.
thaj chaw thov
- Subsea flowlines thiab ntau lawm pipelines

FAQ
Q: Dab tsi yuav tsum tau ceev faj thaum vuam 2507 steel kav?
A: Siv qhov sib txuam 2507 muab tub lim (piv txwv li, ER2594), tswj cov khoom siv hluav taws xob kom tsawg dua lossis sib npaug li 1.5 kJ / mm, thiab tswj qhov kub ntawm qhov sib cuam tshuam tsawg dua lossis sib npaug li 150 degree. Tom qab-weld kev kho cua sov tsis tas yuav tsum tau kho, tab sis yuav tsum tau saib xyuas kom tsis txhob muaj teeb meem theem ua rau hauv tshav kub- thaj chaw cuam tshuam (HAZ).
Q: Cov kev ntsuam xyuas corrosion yog dab tsi ntawm 2507 steel kav?
A: Cov qauv kev xeem suav nrog kev kuaj kev sib xyaw ua ke (ASTM A262 Practice E) thiab pitting corrosion testing (ASTM G48 Method A). Rau kev lag luam roj thiab roj, kev sim ntxiv xws li SSCC (NACE TM0177), HIC (NACE TM0284), thiab kev ntsuam xyuas crevice corrosion tuaj yeem ua.
Q: Koj puas tsuas yog tsim cov kav dej seamless? Koj puas tuaj yeem muab cov kav dej welded?
A: Peb kuj muab ASTM A790 welded kav thiab ASTM A928 welded thiab txias - cov kav dej ua haujlwm kom tau raws li ntau yam kev ntsuas siab.
