ʻO ka ASTM A995 6A ʻelua pāpaʻi pahu pahu he pahu i hana ʻia me ka mea ASTM A995 6A.

Ua ʻike ʻia ka ASTM A995 6A super duplex stainless steel ma ke ʻano o ke kila hoʻolei i ka waena o 1980s. ʻO ka pahuhopu o ka hoʻomohala ʻana, ʻo ia ka hoʻoponopono ʻana i nā mea pāpaʻi koʻikoʻi (loaʻa ka chloride, CO2, H2S, a me nā mea ʻē aʻe) i hoʻohana ʻia i loko o nā māla aila a me ke kinoea ma lalo o ka moana, ma kahi o ke kūpaʻa corrosion kūloko a me ke kūpaʻa ʻaʻahu like ʻole. ʻAʻole lawa ka Zeron25 (25Cr-6Ni-2Mo) duplex kila kila. Ua hoʻohana ʻia ke kila ASTM A995 6A i nā kula he nui, ka mea nui no kona ikaika kiʻekiʻe a me ke kūʻē 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 he kiʻekiʻe ka ʻike o ka chromium a me ka molybdenum, ma muli o ka hopena o ka nitrogen, ke kiʻekiʻe ka mahana ma mua o 1050 ℃, kokoke ka nui o ka ferrite i 50%.

Ma muli o ka maikaʻi o ka mechanical a me ka corrosion, duplex stainless steel ua hoʻohana nui ʻia i ka ʻenekinia waho a me ka hana moku, e like me ke kinoea ʻaila ma waho o ke kai, nā ʻōnaehana wai, nā paila wai hohonu, nā kahua hoʻoheheʻe o waho, nā lako mining subsea, nā moku kaua a me nā moku kūikawā E kali. ʻOiai ʻo ASTM A995 6A duplex stainless steel material he kiʻekiʻe corrosion resistance, ʻo ia nō kahi mea biologically inert, hiki ke hoʻolohi wale i ka nui o ka microbial corrosion, a ʻaʻole hiki ke hoʻopau i ka pōʻino i hoʻokumu ʻia e ka microbial corrosion mai ke kumu kumu.

Wehe ʻia a pani ʻia paha ka lua-plate check valve e wehe a pani ʻia e ke kahe waena a me ka ikaika e pale aku i ke kahe hope o ka valve mai kapa ʻia ʻo ia he valve check. ʻO nā kiwi hoʻomaʻamaʻa he mau kiwi ʻakomi, hoʻohana nui ʻia ma nā paipu me ka holo ʻana o ka media, e ʻae wale i ka media e kahe i ka ʻaoʻao hoʻokahi e pale i nā pōʻino.

ʻO Newsway Valve ASTM A995 6A ua wehe ʻia a pani ʻia nā ʻāpana ʻāpana ʻelua e nānā i ka pahu pahu pahu pālua e ke kahe waena a me ka ikaika e pale i ke kahe ʻana i hope. ʻO nā kiwi hoʻopaʻa pālua pālua no ka ʻāpana o nā kiwi aunoa, ka mea i hoʻohana nui ʻia no nā pipeline me ka holo ʻana o ka media, a ʻae wale i ka media e kahe i kahi ʻaoʻao e pale ai i nā pōʻino. ʻElua mau ʻāpana pōʻai o ka pā pelekane valve check, a hoʻohana ʻia ka pūnāwai e hoʻoikaika i ka hoʻoponopono ʻana. ʻO ka ʻili hoʻopaʻa ʻana hiki ke lilo i ke kino o ka surfacing welding material a i ʻole ka uhi ʻana o ke kino. Loaʻa iā ia kahi ākea o ka hoʻohana a me ka sila hilinaʻi.

Inā makemake ʻoe i nā kikoʻī hou aʻe e pili ana i nā valve e ʻoluʻolu e kelepona iā NSW (newsway valve) keʻena kūʻai

Nā Mea Hana ʻo Newsway Valves

Hiki ke hāʻawi ʻia ke kino valve NSW a me nā mea ʻoki ma ke ʻano Forged a me ke ʻano Casting. Ma hope o nā mea kila kila a me ke kalapona, hana pū mākou i nā valve i nā mea kūikawā e like me ka titanium, nickel alloys, HASTELLOY® *, INCOLOY®, MONEL®, Alloy 20, super-duplex, corrosion resistant alloys a me nā mea papa urea.
