Simbi isina nguraflat welded flangeside fittings inogadzirwa. Iyo gadziriso inofanira kutanga yasvika pakudonha. Iyo poindi ndeyekumisa kamuri yakavharwa pakati peiyo isina tsvinasimbi flangeyemuviri uye yejojo ​​yepombi. Kudzivirira kuvunda pakati pemuviri nestainlesssimbi flangenekuda kwekuchengetedza kudzvanywa, annular mhango inopihwa uko iyo clamp uye yekunze mupendero wesimbi isina tsvina.simbi flangekwemuviri kupindirana. Zino rinobata chisungiso rinoshandiswa semudziyo wekudzivirira nekuti chibatiso chiri padiki dhayamita simbi isina tsvina flange chinogona kutamiswa zviri nyore kune dhayamita diki isina tsvina.simbi flangepanguva jekiseni. Mushure mekunge chisimbiso chaoma panguva yekushanda, tarisa kuzorora kwekunetseka uye ita reinjection yemunharaunda kuvhara chiteshi chejekiseni.

Stainless simbi flat welding flange yekuisa matanho:
1. welding ikozvino haifaniri kunge yakakura, inenge 20% idiki pane kabhoni simbi electrode, arc haigoni kuva yakareba, inter-layer kutonhora haigoni kudzivirira kupisa flange kavha kuparara kunofanira kukurumidza.
2. Iyo electrode inofanira kuomeswa isati yashandiswa. Perovskite mhando inofanira kuomeswa pa150 ° C kweawa imwe uye yakaderera hydrogen mhando inofanira kuomeswa pa200-250 ° C kweawa imwe (usadzokorora kuomesa kanopfuura kamwe chete. Usawedzera welding, welding carbon content kudzivirira electrode coating adhesion. kumafuta uye imwe tsvina, kuitira kuti irege kukanganisa kunaka kwezvikamu.
3. welding Stainless simbi flangepombi fittings, nekuda kwekudzokororwa kudziyisa uye kushora kuramba, carbide precipitation uye mechanical properties.
4. Mushure mekugadzira, iyoflangeyezvakaomeswa CHROMIUM Stainless steel flange fittings yakakura uye iri nyore kutsemuka. Mhando dzakafanana dze chrome-stainless simbi maelectrodes (G202, kana uchishandisa G207) inofanira kunge isati yatanga kupisa kusvika 300 ° C kana kupfuura mushure mekugadzira uye zvishoma nezvishoma kutonhora kusvika 700 ° C mushure mekugadzira. Kana kupisa kurapwa kwe weld kusingagoneki, tsvimbo (A107, A207) inofanira kushandiswa kugadzira simbi isina tsvina flanges.
5. isina tsvinasimbi flange, huwandu hwakakodzera hwezvinhu zvakagadzikana zveTi, Nb, Mo, nezvimwewo, kuitira kuti uvandudze kusimba kwekuora uye weldability, weldability iri nani pane chromium Stainless steel flange, kana uchishandisa mhando imwechete yechromium Stainless steel flange electrode (G302, G307). ), preheat kusvika 200°C kana kupfuura, uye wapedza welding kusvika 800°C hasha. Kana zvisina kudaro, shandisa.
6. simbi isina tsvina flanged tube electrode (A107, A207), isina tsvinasimbi flangedtube fittings, welding flange electrode ine yakanakisa corrosion resistance uye oxidation kuramba inoshandiswa zvakanyanya mukugadzira makemikari, fetereza, peturu, michina yekurapa.
