Simbi isina tsvina inogona kuwanikwa kwese muhupenyu, uye kune mhando dzese dzemhando dzakapusa kusiyanisa. Nhasi kuti ugovane newe chinyorwa kujekesa ruzivo ruzivo pano.
Simbi isiriyo ndeyekupfupika kwesimbi isina simba, mhepo, muputi, mvura uye imwe isina kusimba midhiya kana simbi isina simba inozivikanwa sesimbi isina tsvina; Uye ichave ichipokana nemakemikari anokanganisa midhiya
Simbi isina simba inoreva mhepo, steam, mvura uye imwe isina kusimba midhiya uye acids, salkalis uye mamwe emakemikari anokatyamadza outhorosi, anozivikanwa seStainless acid-inopesana nesimbi. Mukudzidzira, kazhinji isina kusimba yehukama hwehukama hwekushora-kwakashata kunonzi Simbi yesimbi, uye yemakemikari media corrosion-inopesana nesimbi inonzi acid-inopesana nesimbi. Nekuda kwemisiyano mumakemikari ezviviri, iyo yekutanga haina kurwisa kumakemikari media corrosion, nepo yekupedzisira ichiwanzowanzoitika. Iko kukanganisa kupokana kwesimbi isina tsvina kunoenderana nezvinhu zvekufema zvirimo mune simbi.
Kuumbwa kwechiitiko
Zvinoenderana nesangano reSimbi
Kazhinji, maererano nesangano resimbi, manyorerwo estalineless yakakamurwa kuita zvikamu zvitatu: austenitic stainless simbi uye mritensitic simbi uye martensitic simbi. Pahwaro hwesangano rekutanga resalurgical yeaya matatu mapoka, duplex manyorerwo, manyorerwo anoomeswa stain takasviba ane isingasviki 50% simbi inotorwa kune izvo zvinodikanwa chaizvo uye zvinangwa.
1. Austenitic Stainless Simbi
Iyo Matrix kutarisana neCubic Cubstal Sangano reAustenitic (CY chikamu) inotongwa neisiri-mashnet Iyo American Simbi uye Steel Institute kusvika 200 uye mazana matatu akateedzana emamita manhamba, akadai se304.
2. Ferritic Stainless Simbi
Matrix kune Muviri-Center Cubstal chimiro chesangano resangano (chikamu) chiri kutonga, kazhinji, kazhinji hazvigone kuomeswa nekuita kurapwa, asi kushanda kunotonhora kunogona kuita zvishoma kusimbisa simbi simbi. American iron uye simbi Institute kusvika 430 uye 446 yeRebheru.
3. Marrensic stainless simbi
Iyo Matrix is merdency sangano (muviri-concecing cubic kana cubic), magineti, kuburikidza nekushambadzira kurapwa kunogona kugadzirisa zvimiro zvaro zve simbi yesimbi isina tsvina. American iron uye simbi Institute kusvika 410, 420, uye 440 manhamba akaiswa. Martensite ane isangano rekutamba kweAustenitic, iyo inogona kushandurwa kuita martensite (kureva kuti yakaomeswa) kana yakatakurwa kuenda kumhepo tembiricha pachiyero chakakodzera.
4. Austenitic a ferrite (duplex) Type Stainless Simbi
Iyo Matrix ine ese esangano uye iri-ferrite sangano rezvikamu zviviri, izvo zvirimo zvechikamu chevashoma Kuenzaniswa neAustenitic Stainless Simbi, Duplex Steel Simba, kuramba kuyamwisa Corrosion uye chloride kushamwaridzana uye kudzora kukanganisa kwakadzikira zvakanyanya.
5. Precipitation inoomarara simbi isina tsvina
Iyo Matrix ndeyeAustenitic kana yeArmenic Sangano, uye inogona kuomeswa nekunyorova kuomesa kuronga kuita kuti iite simbi isina tsvina. American iron uye simbi Institute kusvika 600 akateedzana emabheji emitambo, akadai se630, kureva 17-4fur.
Kazhinji, kuwedzera kuwanda, kupokana kweAustenitic Simbi kwakakwirira, mune zvakashata zvinokatyamadza, kana zvinhu zvakanyanyisa, iwe unogona kushandisa martensitic simbi uye kufungidzira kushoma simbi.
Hunhu uye kushandisa
Kumusoro maitiro
Kusiyana kwakasiyana
1. Nekuti iyo simbi yeganda yemuchina mukufamba-famba maitiro, marobhoti anoteedzerwa nekudzikiswa zvishoma, zvichikonzerwa nekukanda mvura mativi, kazhinji yakakora pakati pemativi maviri eutete. Mukuyera ukobvu hwemitemo yenyika inofanira kuyerwa pakati penhezi.
2. Chikonzero chekuti kushivirira kwakavakirwa pamusika uye kudiwa kwevatengi, kwakawanzo kukamukana kuve kwakakura uye zvidiki zvidiki.
V. Kugadzira, kuongorora zvinodiwa
1. PIPE PLATE
① DZVIMBORA TUBE PLATE BUTT Majoini ye100% Ray Ongorora kana UT, Yakakodzera Chikamu: RT: ⅱ UT: ⅰ Chikamu;
Kuwedzera kune simbi isina tsvina, yakadururwa pombi pombi yemhepo inosimbisa kupisa kwekunyepa;
③ tube plate gomba bridge wide kutsauka: Maererano neFormula yekuverengera yehupamhi hweHole Bridge: B = (S - D) - D1
Minimum Yakasimba yeHole Bridge: B = 1/2 (s - d) + c;
2. THUBE Bhokisi Kupisa Kurapa:
Carbon Steel, yakaderera Alloy Steel neyekupararira kweBhokisi reCylinder Pipi bhokisi, mukushandiswa kwekusimbisa kwekunetseka kwekunzwa kurapa
3. Kudzvinyirira bvunzo
Kana iyo shell process dhizaini yakaderera pane iyo tube process kumanikidza, kuti utarise mhando yeiyo yekupisa expanger tube uye tube plate connections
① Shell chirongwa chekumanikidza kuwedzera kudzvanywa kwekuyedza nehurongwa hwePIPE kuwirirana neHydraulic test, kuti utarise kana iyo yekudzima pombi majoini. .
【Kana iyo nzira iri pamusoro haina kukodzera, iyo ganda rinogona kunge riri hydrostatic test maererano nekumanikidzwa kwekutanga mushure mekupfuura, uyezve ganda reAmmonia bvunzo kana kuongororwa kweHologen Leage.
Rudzii rwesimbi isina tsvina haisi nyore kutuka?
Pane zvinhu zvitatu zvakakosha zvinokanganisa ngura yesimbi isina tsvina:
1.the zvemukati zvezvinhu zvekunyepedzera. Kazhinji, zvirimo zvechromium muna 10.5% simbi haisi nyore kuimba. Zvepamusoro zvemukati zvechromium uye nickel corrostion kupesana zviri nani, senge makumi matatu emhando yepamusoro yezvinyorwa zve85 ~ ~ 10%, chrromium ye18% ~
2. Maitiro ekunyepedzera we mugadziri anozochinjawo kukosha kweiyo corrosance yesimbi isina tsvina. Kunyemwerera tekinoroji yakanaka, inokatyamadza, yakakura tekinoroji, kubviswa kwezvinhu zvekutamba, saka mhando yechigadzirwa yakagadzikana uye yakavimbika, isina kunaka, isina kunaka mhando yekunhuhwirira. Kusiyana neizvozvo, mamwe madiki midziyo yechidyarwa kumashure, backgreatment technology, yekunyomba maitiro, kusviba hakugone kubviswa, kugadzirwa kwezvigadzirwa kuchadzikama.
3. Kunze kwenzvimbo. Iyo yakaoma uye yakashata nharaunda haisi nyore kunhuwa, nepo mweya humbowo, mamiriro ekunze ekunaya, kana mhepo ine acidity uye alkalinity yemagariro zviri nyore kutariswa. 304 Chinyorwa chesimbi chisina simba, kana nharaunda yakapoteredzwa yakanyanya murombo.
Stainless Simbi Rust Spots Maitiro Ekuita Naye?
1.chemical nzira
Nekutora paste kana kupfira kuti ubatsire zvikamu zvaro zvekudzora kuumbwa kweiyo chromium oxpances, mushure mekubvisa zvese zvakasvibisa uye acid zvasara, zvakakosha kuita sendudzi rakakodzera nemvura. Mushure mekunge zvese zvagadziriswa uye kufuridzirwa nemidziyo inoputika, inogona kuvharwa nekuputika pax. Zvematunhu emuno emunharaunda anogona zvakare kushandiswa 1: 1 peturu, musanganiswa weoiri neakachena njanji kuti ipukunde nzvimbo dzekunze dzinogona kuve.
2. Maitiro maitiro
Sandbeb kusingaperi kuchenesa, kuchenesa negirazi kana ceramic zvimedu zvinoputika, kukurudzira, kutsvaira nekupukuta. Nzira dzechiraniki dzine mukana wekupukuta kusvibiswa zvakakonzerwa zvakambotorwa zvinhu, kupukuta zvinhu kana zvinhu zvakadzikira. Mhando dzose dzekusvibiswa, kunyanya zvimedu zvesimbi zvevatorwa, zvinogona kuve zvinopesana, kunyanya munzvimbo dzakanyorova. Naizvozvo, makanika akacheneswa nzvimbo dzinofanirwa kucheneswa chaizvo pasi pemamiriro akaoma. Iko kushandiswa kwenzira dzemuchinjiro dzinongochenesa nzvimbo kwayo uye hakuchinje kupesana kwezvinhu izvo pachavo. Naizvozvo, zvinokurudzirwa kuRipururiturure pamusoro pemidziyo yekupukuta uye kuvhara iyo nePolising WAX mushure mekuchenesa mechances.
