ʻO ka ASTM A995 6A pālua pā hōʻoia valve kahi valve i hana ʻia me ka mea ASTM A995 6A.

Ua ʻike ʻia ke kila kila super duplex ASTM A995 6A ma ke ʻano o ke kila i hoʻolei ʻia i ka waena o nā makahiki 1980. ʻO ka pahuhopu hoʻomohala ka hoʻoponopono ʻana i nā mea media ʻino (loaʻa ka chloride, CO2, H2S, a me nā mea ʻē aʻe) i hoʻohana ʻia i nā kahua aila a me ke kinoea subsea, ma kahi o ke kūpaʻa kūloko a me ke kūpaʻa like ʻana o ka corrosion. ʻAʻole lawa ka kila kila duplex Zeron25 (25Cr-6Ni-2Mo). Ua hoʻohana ʻia ke kila ASTM A995 6A ma nā ʻano he nui, ʻo ia hoʻi no kona ikaika kiʻekiʻe a me ke kūpaʻa ʻana i ka corrosion kūloko a me ka corrosion stress o ka chloride. Loaʻa i ke kila ka nitrogen kiʻekiʻe, nona ka hopena o ka hoʻopaʻa ʻana i ka austenite. ʻOiai ke kiʻekiʻe o ka ʻike o nā mea chromium a me molybdenum, ma muli o ka hopena o ka nitrogen, i ka wā e ʻoi aku ai ka mahana ma mua o 1050 ℃, kokoke nō ka nui o ka ferrite i 50%.

Ma muli o kona mau waiwai mechanical maikaʻi a me ke kūpaʻa ʻana i ka corrosion, ua hoʻohana nui ʻia ke kila kila duplex i ka ʻenekinia kai a me ke kūkulu moku, e like me ke kinoea kahua aila kai, nā ʻōnaehana wai, nā pamu wai hohonu, nā kahua ʻeli kai, nā lako hana mining subsea, nā moku kaua a me nā moku kūikawā. ʻOiai ʻo ka mea kila kila duplex ASTM A995 6A he kūpaʻa kiʻekiʻe i ka corrosion, he mea inert biologically nō ia, hiki ke hoʻolohi wale i ka wikiwiki o ka microbial corrosion, a ʻaʻole hiki ke hoʻoponopono i ka pōʻino i hoʻokumu ʻia e ka microbial corrosion mai ke kumu.

ʻO ka lālā wehe a pani ʻana o ka valve nānā pālua-papa e wehe ʻia a pani ʻia paha e ke kahe waena a me ka ikaika e pale aku i ke kahe hope o ka valve mai ka kapa ʻia ʻana he valve nānā. ʻO nā valve nānā he mau valves aunoa, hoʻohana nui ʻia ma nā paipu me ke kahe hoʻokahi ala o ka media, e ʻae ana i ka media wale nō e kahe i hoʻokahi ala e pale aku i nā pōpilikia.

ʻO Newsway Valve ASTM A995 6A pālua papa nānā pani ʻāpana wehe/pani ʻia e ke kahe waena a me ka ikaika e pale aku i ke kahe ʻana o ke waena. No nā pālua papa nānā i ka māhele o nā kiwikā aunoa, kahi i hoʻohana nui ʻia no nā paipu me ke kahe hoʻokahi ala o ka media, a ʻae wale i ka media e kahe i hoʻokahi ʻaoʻao e pale aku i nā ulia. ʻElua mau hapalua pōʻai ka papa butterfly check valve, a hoʻohana ʻia ka pūnāwai e koi i ka hoʻihoʻi hou ʻana. Hiki i ka ʻili sila ke lilo i mea pale ʻaʻahu o ke kino a i ʻole ka uhi laholio. Loaʻa iā ia kahi ākea o ka hoʻohana a me ka sila hilinaʻi.

Inā makemake ʻoe i nā kikoʻī hou aku e pili ana i nā valves e ʻoluʻolu e kelepona i ka ʻoihana kūʻai aku ʻo NSW (newsway valve)
