High pressure Stainless steel tube mugadziri
316L imhando yesimbi isina tsvina, AISI 316L ndiyo inoenderana neAmerican brand uye Sus 316L ndiyo inoenderana neJapan mhando. China yakabatana kodhi yedhijitari ndeye s31603, iyo yakajairwa brand ndeye 022cr17ni12mo2 (itsva chiyero), uye mhando yekare ndeye 00Cr17Ni14Mo2, iyo inoratidza kuti inonyanya kuve neCr, Ni uye Mo, uye nhamba inoratidza iyo inenge muzana. Iyo yenyika chiyero ndeye GB / T 20878-2007 (yazvino edition). 316L inoshandiswa zvakanyanya muindasitiri yemakemikari nekuda kweiyo yakanakisa corrosion resistance. 316L isimbi inotorwa kubva ku18-8 austenitic simbi isina tsvina, ine 2 ~ 3% Mo yakawedzerwa. Pahwaro hwe316L, mamakisi mazhinji esimbi anotorwawo. Semuenzaniso, 316Ti inotorwa mushure mekuwedzera zvishoma zveTi, 316N inotorwa mushure mekuwedzera zvishoma zveN, uye 317L inotorwa nekuwedzera zvinyorwa zveNi uye mo.
Mazhinji e316L aripo pamusika anogadzirwa zvinoenderana neAmerican zviyero. Mukufunga nezve mutengo, zvigayo zvesimbi zvinowanzo dzikamisa iyo Ni yezvigadzirwa kune yakaderera muganho sezvinobvira. Chiyero cheAmerica chinoti Ni content ye316L i10 ~ 14%, uye chiyero cheJapan chinoti Ni content ye316L i12 ~ 15%. Zvinoenderana neiyo shoma mwero, pane musiyano we2% muNi yemukati pakati peAmerican Standard neJapan standard, iyo inoratidzwa mumutengo. Naizvozvo, vatengi vachiri kuda kuona kuti chigadzirwa chinoreva ASTM kana JIS chiyero kana uchitenga 316L zvigadzirwa.
Iyo Mo yemukati ye316L inoita kuti simbi ive neyakanakisa gomba corrosion resistance uye inogona kuiswa zvakachengeteka kunharaunda ine halogen ions seCl -. Sezvo 316L ichinyanya kushandiswa kune ayo emakemikari zvimiro, zvigayo zvesimbi zvine zvishoma zvakaderera zvinodiwa zvekutariswa kwepasi kwe316L (zvichienzaniswa ne304), uye vatengi vane yakakwirira yepamusoro zvinodiwa vanofanira kusimbisa kutariswa kwepasi.
Iwo maviri anonyanya kushandiswa simbi isina tsvina 304316 (kana 1.4308,1.4408 inoenderana neGerman / European zviyero), mutsauko mukuru pakati pe316 ne304 mukuumbwa kwemakemikari ndewekuti 316 ine Mo, uye inowanzo zivikanwa kuti 316 ine zvirinani corrosion resistance uye iri yakawanda inodzivirira kupisa kupfuura 304 munzvimbo yakakwirira yekupisa. Naizvozvo, munzvimbo yepamusoro tembiricha, mainjiniya anowanzo sarudza 316 zvikamu. Asi icho chinonzi chinhu hachisi mhedziso. Munzvimbo yakanyanyisa sulfuric acid, usashandise 316 pane chero kupisa kwakanyanya. Zvikasadaro, ichave yakakura. Vanhu vanodzidza makanika vese vakadzidza shinda. Ndichiri kuyeuka mafuta akasviba akasimba anoda kuiswa kudzivirira tambo kuti dzisarume pakupisa kwakanyanya: molybdenum disulfide (MoS2), kubva panogona kutorwa mhedziso mbiri: chekutanga, Mo ndeyechokwadi-inodzivirira tembiricha (unoziva? goridhe rei rinonyungudutswa mukati? Molybdenum crucible!). 2: Molybdenum inopindirana zviri nyore ine high valence sulfur ions kuita sulfide. Naizvozvo, hapana simbi isina Stainless isingakundiki uye inodzivirira ngura. Mukuongorora kwekupedzisira, simbi isina tsvina isimbi ine tsvina yakawanda (asi izvi zvinosvibisa zvinonyanya kusagadzikana kupfuura simbi). Kana iri simbi, inogona kuita nezvimwe zvinhu.
