Katup mriksa piring ganda ASTM A995 6A yaiku katup sing digawe saka bahan ASTM A995 6A.
ASTM A995 6A baja tahan karat super duplex muncul ing bentuk baja tuang ing pertengahan 1980-an. Tujuan pangembangan yaiku kanggo ngatasi bahan media sing atos (ngemot klorida, CO2, H2S, lan liya-liyane) sing digunakake ing lapangan minyak lan gas subsea, tinimbang tahan korosi lokal lan resistensi karat seragam. Ora cukup Zeron25 (25Cr-6Ni-2Mo) baja tahan karat dupleks. Baja ASTM A995 6A wis digunakake ing pirang-pirang lapangan, utamane kanggo kekuatan dhuwur lan tahan kanggo korosi lokal lan karat karat klorida. Baja ngandhut nitrogen sing luwih dhuwur, sing nduweni efek stabilisasi austenit. Senajan isi kromium lan unsur molybdenum dhuwur, amarga efek saka nitrogen, nalika suhu luwih saka 1050 ℃, jumlah ferrite isih cedhak 50%.
Amarga sifat mekanik sing apik lan tahan korosi, baja tahan karat duplex wis akeh digunakake ing teknik lepas pantai lan galangan kapal, kayata gas lapangan minyak lepas pantai, sistem banyu, pompa banyu jero, platform pengeboran lepas pantai, peralatan pertambangan subsea, kapal perang lan kapal khusus Enteni. Sanajan bahan baja tahan karat duplex ASTM A995 6A nduweni resistensi karat sing dhuwur, nanging isih minangka bahan inert biologis, sing mung bisa nyuda tingkat karat mikroba kanthi efektif, lan isih ora bisa ngatasi cilaka sing disebabake dening karat mikroba saka panyebab oyod.
Bukaan lan tutup tutup katup dual-plate dibukak utawa ditutup kanthi aliran medium lan kekuwatan kanggo nyegah aliran mburi katup kasebut diarani katup mriksa. Katup mriksa minangka katup otomatis, utamane digunakake ing pipa kanthi aliran media siji-sijine, mung ngidini media kasebut mili ing siji arah kanggo nyegah kacilakan.
Katup Newsway ASTM A995 6A bagean pambuka / tutup tutup katup piring kaping pindho dibukak utawa ditutup kanthi aliran medium lan meksa supaya medium ora mili bali. Klep mriksa piring dual kalebu ing kategori katup otomatis, sing utamane digunakake kanggo saluran pipa kanthi aliran media siji arah, lan mung ngidini media mili ing arah siji kanggo nyegah kacilakan. Plat kupu katup mriksa rong setengah bunderan, lan spring digunakake kanggo meksa reset. Lumahing sealing bisa dadi bahan tahan las lumahing awak utawa lapisan karet. Wis sawetara saka sudhut nggunakake lan sealing dipercaya.
