1. Kufuridzirwa kwekushisa kwekushisa kwekushisa
Kugadziriswa kwekugadzirisa ndiyo inonyanya kushanda kunyorovesa maitiro ekurapa austenitic Stainless simbi.Iyo welded pombi mushure mekugadziriswa kwekugadzirisa inogona kuwana yakanakisa corrosion resistance, yakaderera simba uye nani plastiki.Nenzira iyi chete inogona kusangana nezvinodiwa zvemapombi eindasitiri senge condenser pombi nemapombi emakemikari.
Zvinoenderana nezvinodiwa zvakajairwa zvemapombi esimbi asina simbi emacondensers, tembiricha yekupisa yeaustenitic simbi isina tsvina yakashongedzwa pombi inofanira kusvika 1050 ~ 1150 ℃.Panguva imwecheteyo, inodiwawo kuti mukati uye kunze kwekunze kwepaipi yakashongedzwa mushure mekupisa kupisa kwakachena uye kwakatsetseka, pasina oxidation ruvara.Nokudaro, zvinotarisirwa kuti zvive zvakasimba panguva yekupisa uye kutonhora kwepombi dzakasungirirwa.Kudzora tembiricha shanduko yemhando (muchoto chechoto), pombi yesimbi inofanirwa kunge iri munzvimbo yakanaka yekudzivirira, uye nzira yekudzima mvura yechinyakare haigone kushandiswa kudzivirira tembiricha yepamusoro yesimbi pombi kubva pakuora okisijeni uye oxidizing pamusoro pepombi. .Kazhinji, iyo tembiricha yekurapa yeaustenitic simbi isina tsvina ndeye 1050 ~ 1150 ℃.Kana tembiricha iyi isingasviki, chimiro chemukati che austenitic simbi isina kusimba haina kugadzikana, uye carbides inonaya, zvichiita kuti pamusoro pepombi yesimbi isingasviki muvara wakajeka, uye pamusoro pepombi ichaita yakasviba.
2. Pesvedzero yekudzivirira gasi
Kupisa kwekupisa kwesimbi isina tsvina yakashongedzwa pombi inotora oxidation-isina inoramba ichipisa kupisa yevira ine inodzivirira gasi, iyo inogona kuwana inopenya nzvimbo isina oxidation, nekudaro ichibvisa echinyakare pickling process.Iwo magasi ekudzivirira anogona kushandiswa akakwirira-kuchena hydrogen, yakaora ammonia uye mamwe magasi ekudzivirira.Sezvo simbi isina tsvina yakashongedzwa pombi ine chromium, hazvibviri kuita inopenya kupisa kurapwa mune yakajairwa gasi rekudzivirira (senge hydrocarbon decomposition gas, nezvimwewo), uye zviri nani kuzviita munzvimbo yekutsvaira.Zvisinei, nokuda kwekupisa kwekupisa kwe-in-line-stainless steel welded pombi, nzvimbo yevacuum haigoni kushandiswa, uye gasi inert (yakadai seargon) inogona kushandiswa.Kunyangwe kushandiswa kwegasi inert segasi rinodzivirira rekupisa kurapwa kwe austenitic simbi isina tsvina yakashongedzwa mapaipi ine hunhu hwekusatora chikamu mukuita kwemakemikari, kushanda kuri nyore, kwakachengeteka uye kwakavimbika, asi haina kudzikisa zvivakwa, kuitira kuti kupisa kurapa mhedzisiro. haigone kusangana neyakajeka inopenya yemhando yekurapa zvinodiwa.Silver grey.Uyezve, mutengo weinert gasi wakakwira uye hauna kukodzera kugadzirwa kwakakura.Maererano tsvakurudzo pamusoro kupisa kurapwa muitiro uye kuongorora uye akadzokororwa miedzo pamusoro kunaka Stainless simbi welded pombi pashure kupenya kupisa kurapwa, nzira yokutanga kushandisa inert gasi kuchenesa mhepo ari kupisa kurapwa choto, uye ipapo kutsiva inert gasi ine hydrogen, yaratidza kuti kupenya kupisa kurapwa kwave kuwanikwa.Hunhu hunodiwa. Hangao Tech (SEKO Machinery) kuchengetedza kupisa kunopenya annealing kupisa kupisa muchina ndeye online mhando midziyo, yakanyatsogadzirirwa simbi isina tsvina yakashongedzwa pombi yekugadzira mitsetse.
3. Kufurira kwekushisa kwekutonhora
Mushure mekupisa simbi isina tsvina yakasungwa pombi kusvika 1050 ~ 1150 ℃, iyo welded pombi inofanira kukurumidza kutonhora pasi.inofanira kudzikiswa kune tembiricha isina oxidize.Nokudaro, kutonhora kwekutonhora kwakakosha zvikuru, uye hutanho hwekushisa hunofanira kunyatsodzorwa.

4. Kufurira kwe welded pombi pamusoro
Mamiriro epamusoro pesimbi isina tsvina yakashongedzwa pombi isati yapinda muchoto ine simba guru pakugadzirisa kupisa kwakajeka.Kana iyo pamusoro pepombi yakashongedzwa yakasvibiswa nehunyoro, girisi uye imwe tsvina muchoto, ruvara rwegirini rweokisijeni rwakajeka ruchaonekwa pamusoro pepombi yakashongedzwa mushure mekupisa kwekupisa.Nokudaro, vasati vapinda muchoto chekupisa kupisa, pamusoro pesimbi isina tsvina yakashongedzwa pombi inofanira kuva yakachena kwazvo, uye pamusoro pepombi yakasungirirwa haifaniri kubvumirwa kuva nehunyoro.Kana zvichidikanwa, inogona kuomeswa muomesi kutanga, uye wozoisa muchoto.
5. Kufurira kweKupisa Kurapa Furnace Kuvhara
Kupisa kwevira kwemoto kunofanira kuvharwa uye kuparadzaniswa nemhepo yekunze.Kunyanya nzvimbo iyo pombi yakashongedzwa inopinda muchoto chechoto uye nenzvimbo iyo pombi yakashongedzwa inobuda muchoto chechoto, mhete yekuisa chisimbiso munzvimbo idzi inonyanya kupfekwa, saka inofanira kuongororwa kazhinji uye kuchinjwa nenguva.Kuti udzivirire micro-leakage, gasi rinodzivirira muchoto rinofanira kuchengetedza imwe dzvinyiriro yakanaka.Kana iri hydrogen inodzivirira gasi, inowanzodiwa kuti ive yakakura kupfuura yakajairwa atmospheric pressure.
6. Kufurira kwezvimwe zvinhu pakurapa kupisa kwakajeka
Munguva yekushanda, zvakakosha kuve nechokwadi kuti welding inoenderera uye yakagadzikana.Kana paine maburi kana seams papombi yakashongedzwa, basa revira rekupisa kupisa rinofanira kumira, kana zvisina kudaro pombi yakashongedzwa inogona kuputika muchoto.Mukuwedzera, iyo welding mhedzisiro haina kunaka, uye mhepo kana mwando wakapfapfaidzwa kubva mugomba welding uchaparadza mhepo inodzivirira muchoto uye inokanganisa kupenya kwekupisa kupisa.
