ASTM A995 6A dual phaj kos valve yog lub valve ua los ntawm ASTM A995 6A cov khoom.

ASTM A995 6A super duplex stainless hlau tau tshwm sim nyob rau hauv daim ntawv ntawm cam khwb cia hlau nyob rau hauv nruab nrab-1980s. Lub hom phiaj ntawm txoj kev loj hlob yog los daws cov xov xwm hnyav (muaj cov tshuaj chloride, CO2, H2S, thiab lwm yam) cov ntaub ntawv siv nyob rau hauv subsea roj thiab roj teb, es tsis txhob ntawm lub zos corrosion kuj thiab uniform corrosion kuj. Tsis txaus Zeron25 (25Cr-6Ni-2Mo) duplex stainless hlau. ASTM A995 6A steel tau siv nyob rau hauv ntau lub teb, feem ntau yog rau nws lub zog siab thiab tsis kam mus rau hauv zos corrosion thiab kev nyuaj siab corrosion ntawm chloride. Hlau muaj nitrogen ntau dua, uas muaj cov nyhuv stabilizing austenite. Txawm hais tias cov ntsiab lus ntawm chromium thiab molybdenum ntsiab yog siab, vim muaj cov nyhuv ntawm nitrogen, thaum kub siab tshaj 1050 ℃, cov nyiaj ferrite tseem nyob ze rau 50%.

Vim nws cov khoom siv zoo thiab kev tiv thaiv corrosion, duplex stainless hlau tau dav siv nyob rau hauv offshore engineering thiab shipbuilding, xws li offshore oilfield gas, dej systems, dej twj tso kua mis, offshore drilling platforms, subsea mining khoom, warships thiab tshwj xeeb ships tos. Txawm hais tias ASTM A995 6A duplex stainless hlau cov khoom muaj kev tiv thaiv corrosion siab, nws tseem yog cov khoom siv roj ntsha tsis zoo, uas tuaj yeem txo qis tus nqi ntawm microbial corrosion, thiab tseem tsis tuaj yeem daws qhov teeb meem los ntawm microbial corrosion los ntawm cov hauv paus hauv paus.

Ob lub phaj kos valve qhib thiab kaw cov tswv cuab yog qhib lossis kaw los ntawm qhov nruab nrab ntws thiab lub zog los tiv thaiv lub nraub qaum ntawm lub valve los ntawm kev hu ua lub tshev valve. Kos li qub yog tsis siv neeg li qub, feem ntau yog siv rau hauv cov kav dej nrog ib txoj kev khiav ntawm kev tshaj tawm, cia tsuas yog cov xov xwm ntws mus rau hauv ib qho kev coj los tiv thaiv kev sib tsoo.

Newsway Valve ASTM A995 6A dual phaj kos valve qhib / kaw qhov chaw qhib lossis kaw los ntawm qhov nruab nrab ntws thiab quab yuam kom tiv thaiv qhov nruab nrab ntawm ntws rov qab. Dual phaj check li qub yog nyob rau hauv qeb ntawm tsis siv neeg li qub, uas yog tsuas yog siv rau cov kav dej nrog ib-txoj kev khiav ntawm kev tshaj tawm, thiab tsuas yog tso cai rau cov xov xwm ntws mus rau hauv ib qho kev taw qhia kom tsis txhob muaj xwm txheej. Lub check valve npauj npaim phaj yog ob lub voj voog, thiab lub caij nplooj ntoos hlav yog siv los yuam kom rov pib dua. Lub sealing nto tuaj yeem yog lub cev qhov chaw vuam cov khoom siv tiv thaiv lossis roj hmab hauv ob sab phlu. Nws muaj ntau yam kev siv thiab txhim khu kev qha sealing.
