2507 duplex Stainless steel valve inoshandisa JB/T7746 “Compactsimbi vharafu” indasitiri mwero sumo
Kambani yedu inoshanda mukugadzirwa kwemvura yegungwa 2205 duplex simbi isina simbi bhora vharafu 2507 duplex Stainless simbi bhora vharafu 2205 duplex Stainless simbi globe vharafu 2507 duplex Stainless simbi globe valve 2205 duplex Stainless simbi gedhi vharafu 2507 simbi isina duplex simbi simbi 2507 stain simbi simbi 2507 stain simbi simbi. mhando sefa 2507 duplex Stainless simbi sefa 2205 cheki vharafu 2507 cheki vharafu uye zvimwe zvigadzirwa
Mvura yegungwa 2205 duplex simbi vharafu molybdenum duplex Stainless simbi ine kumira zvakanaka kune chloride stress corrosion pasi pekunetseka kwakaderera. Kazhinji, 18-8 mhando austenitic Stainless simbi inogara ichinetsekana nekutyoka kwegora mune neutral chloride mhinduro pamusoro pe60C. Heat exchanger, evaporators uye zvimwe midziyo yakagadzirwa nemhando iyi yesimbi isina tsvina muindasitiri yepakati yetrace chloride uye hydrogen sulfide ine tsika yekuburitsa kusagadzikana ngura kutsemuka, nepo duplex Stainless simbi ine kumira zvakanaka.
(2) Mvura yegungwa 2205 duplex simbi vharafu molybdenum duplex Stainless simbi ine kunaka ngura kuramba. Iyo yakakosha gomba inokwanisa ye duplex simbi isina tsvina yakafanana neye austenitic simbi isina tsvina ine yakafanana pitting resistance (PRE = Cr% + 3.3Mo% + 16N%). Kudzivirirwa kwekuora kwe duplex Stainless simbi uye austenitic Stainless simbi yakafanana neiyo yeAI 316L. Kudzivirirwa kwekuora kwepamusoro chromium duplex simbi isina tsvina ine 25% Cr, kunyanya nitrogen, yakakwirira kudarika iyo yeAI 316L.
(3) Nekunaka kwegora kuramba kuneta uye kupfeka kuita ngura. Mune dzimwe corrosive medium mamiriro ezvinhu, akakodzera kugadzirwa pombi, mavharuvhu uye mamwe magetsi midziyo.
(4) Yakanaka yakazara ma mechanical zvivakwa. Simba rakakwirira uye kuneta simba, goho simba iri 18-8 mhando austenitic Stainless simbi 2 nguva. Munzvimbo yakasimba yekugadzirisa, kureba kunosvika 25%, uye kukosha kwekuoma AK (V-notch) iri pamusoro pe100J.
(5) Weldability yakanaka, diki inopisa inoputika tsika, kazhinji isati yatungidzirwa pasina preheating, welding pasina kupisa kupisa, inogona kugadzirwa ne18-8 mhando austenitic simbi isina kana kabhoni uye zvimwe zvakasiyana.
(6) Kupisa kwekushanda kwekushisa kweye duplex simbi isina simbi ine yakaderera chromium (18% Cr) yakakura kupfuura iyo ye18-8 austenitic simbi isina tsvina, uye kuramba kudiki. Inogona kukungurutswa yakananga kugadzira simbi ndiro isina kuforoma. Duplex simbi isina simbi ine yakakwira chromium (25% Cr) yakaoma zvishoma pane austenitic stainless simbi yekupisa, inogona kugadzirwa ndiro, chubhu uye waya zvigadzirwa.
(7) kutonhora kushanda kupfuura 18-8 mhando austenitic Stainless simbi basa kuomesera mhedzisiro yakakura, muchubhu, ndiro deformation panguva yekutanga nhanho, inoda kuisa kushushikana kukuru kune deformation.
(8) Kuenzaniswa neaustenitic Stainless simbi, high thermal conductivity, yakaderera linear yekuwedzera coefficient, inokodzera midziyo yekugadzira uye kugadzirwa kwecomposite plate. Iyo yakakodzerawo kugadzira iyo chubhu yepakati yekupisa inopisa, uye kupisa kwekushisa kwakakwira kupfuura iyo yeaustenitic simbi isina tsvina.
(9) Pachine zvakasiyana-siyana zvebrittleness maitiro epamusoro chromium ferrite simbi isina tsvina, haifaniri kushandiswa munzvimbo yakakwirira kupfuura 300C yekushanda. Iyo yakaderera iyo chromium yemukati ye duplex simbi isina tsvina, ishoma kukuvadzwa kweiyo yakaenzana brittle chikamu.
JB/T7746 "Compact Steel Valve" Indasitiri yakajairika inosuma yazvino dhizaini nekugadzira chiyero chekugadzira simbi diki dhayamita vharafu munyika yedu JB/T 7746-2006 "Compact Steel Valve", chiyero chakatenderwa uye chakaburitswa munaGunyana 14, 2006. , zuva rekushandiswa ndiMarch 1, 2007.
