Kev piav txog

Lub Gate lub rooj vag valve yog ib qho chaw muaj khoom ntawm cov khoom siv duplex steel, tshwj xeeb tshaj plaws 2205 lossis 2507, uas cov khoom ua kom muaj zog thiab corrosion kuj cov yam ntxwv. Hom valve no yog tsim nyog tshwj xeeb rau cov xov xwm corrosive ib puag ncig, xws li acids, seasater, dej hiav txwv, thiab tshuaj chloride ions.

Cov yam ntxwv tseem ceeb:

1. Lub zog siab: cov txiaj ntsig lub zog yog ntau dua ob zaug ntawm kev ua tsis zoo ntawm cov hlau

2. Zoo heev corrosion: Muaj peev xwm tiv thaiv kev ntxhov siab corrosion hauv chloride ion qhov chaw tsis zoo ntawm 2205 dulex steel zoo dua li ntawm 316L Austenitic Stainless hlau

3. Nyob rau hauv corrosion Kuj: piv nrog Austenitic Stainless hlau nrog cov ntsiab lus alloy sib npaug, nws muaj cov hnav zoo dua thiab ua rau muaj kev tiv thaiv zoo dua
