Flange maitiro uye shandisa kutarisa

Flangeszvikamu zvakaita sedhisiki zvinowanzoshandiswa pakupomba.Flangesanoshandiswa ari maviri maviri uye nekufananidzaflangespamavharuvhu. Mukugadzira pombi,flangesanonyanya kushandiswa pakubatanidza mapaipi. Mukuda kwekubatanidza pombi, marudzi ese ekugadzwa kweflange, pombi yakaderera inogona kushandisa wayaflange, kushandiswa kwewelding flange inopfuura 4 kilograms yekumanikidza. Wedzera kuvhara gasket pakati pemaviriflanges, wobva wasimbisa nebhaudhi.Flangesnemadzvinyiriro akasiyana ane ukobvu hwakasiyana uye shandisa mabhaudhi akasiyana.

Kuenzaniswa nekabhoni simbi, Stainless simbi ine zvinotevera maitiro:
1) high electric negative rate, inenge 5 times of carbon steel.
2) Yakakura mutsara wekuwedzera coefficient, 40% yakakura kupfuura kabhoni simbi, uye nekuwedzera kwekushisa, mutsara wekuwedzera coefficient yekukosha inowedzerwawo zvinoenderana.
3) Low thermal conductivity, inenge 1/3 ye carbon steel.
Cherechedza:
1. Kuti udzivise kuora pakati pemaziso nekuda kwekupisa kwechifukidziro cheflange, ikozvino welding haifaniri kunge yakakura, inenge 20% pasi pe carbon steel electrode, iyo arc haifaniri kunge yakareba, iyo inokurumidza kutonhora. pakati pezvikamu, uye yakamanikana weld bead yakakodzera.
2. iyo electrode inofanira kuchengetwa yakaoma kana yakashandiswa, titanium calcium type inofanira kuomeswa ne150 ℃ kweawa imwe, yakaderera A hydrogen type inofanira kuomeswa ne200-250 ℃ kweawa 1 (kwete kudzokororwa kuomeswa, kana zvisina kudaro kuvhara kuri nyore crack and flake), kudzivirira iyo electrode coating stick oil uye imwe tsvina, kuitira kuti isawedzera kabhoni yemukati yewelding seam uye kukanganisa kunaka kwezvikamu zvewelding.

3.flangepombi welding, nekudzokororwa kudziya kwecarbide kunaya, kuderedza kushomeka kwekupokana uye michina.
4. chromeflangemafittings after welding kuomesa American standard flange yakakura, iri nyore kutsemuka. Kana iyo imwe mhando yechromium Stainless simbi electrode (G202, G207) welding, inofanira kuitwa pamusoro pe300 ℃ preheating uye inenge 700 ℃ mushure mekuputira kunonoka kutonhora kurapwa. Kana iyo weldment isingakwanisi kurapwa mushure mekutsvaira, flanged pombi electrode (A107, A207) ichashandiswa.
5.flange, kuitira kuti uvandudze kurwisana kwekuora uye weldability uye kuwedzera huwandu hwakakodzera hwekugadzikana kwezvinhu Ti, Nb, Mo, nezvimwewo, weldability iri nani pane chrome flange. Paunenge uchishandisa mhando imwe chete yechromium flange electrode (G302, G307), inofanira kunge isati yapisa pamusoro pe200 ℃ uye kudzikamiswa mushure mekunama pa800 ℃. Kana iyo weldment isingakwanisi kupisa kupisa, flanged pombi welding electrode (A107, A207) inofanira kushandiswa.
6.Flangedpombi fittings, bhatani-weldingflangeelectrode ine yakanaka corrosion resistance uye oxidation kuramba, inoshandiswa zvakanyanya mumakemikari, kemikari fetiraiza, peturu, kugadzira michina yekurapa.
