Tilmaamaha Flange oo isticmaal feejignaan

Flangeswaa qaybo qaabaysan oo inta badan loo isticmaalo tuubooyinka.Flangeswaxaa loo isticmaalaa laba-labo iyo is-barbardhiggarbahaalwaaxyada. Injineerinka dhuumaha,garbahawaxaa inta badan loo isticmaalaa isku xirka dhuumaha. Baahida loo qabo in lagu xiro dhuumaha, dhammaan noocyada rakibaadda ee flange, dhuumaha cadaadiska hooseeya waxay isticmaali karaan siliggarab, isticmaalka flange alxanka in ka badan 4 kiiloogaraam oo cadaadis ah. Ku dar gaaska daboolaya inta u dhaxaysa labagarbaha, ka dibna ku dheji bot.Flangesoo leh cadaadis kala duwan ayaa leh dhumucyo kala duwan waxayna isticmaalaan boolal kala duwan.

Marka la barbar dhigo birta kaarboonka, birta aan lahayni waxay leedahay sifooyinka soo socda:
1) Heerka taban ee koronto oo sarreeya, qiyaastii 5 jeer oo birta kaarboon ah.
2) Isku xidhka fidinta toosan ee waaweyn, 40% ka weyn birta kaarboonka, iyo korodhka heerkulka, isku xidhka fidinta tooska ah ee qiimaha ayaa sidoo kale loo kordhiyaa si waafaqsan.
3) Dhaqdhaqaaqa kulaylka hooseeya, qiyaastii 1/3 ee birta kaarboon.
Fiiro gaar ah:
1. Si looga hortago daxalka u dhexeeya indhaha sababtoo ah kululaynta daboolka flange, hadda alxanka waa inuusan noqon mid aad u weyn, oo ku saabsan 20% ka yar electrode birta carbon, arc waa inuusan noqon mid aad u dheer, qaboojinta degdega ah. inta u dhaxaysa lakabyada, iyo kuul alxanka cidhiidhi ah ayaa ku habboon.
2. electrode waa in lagu hayaa qalalan marka la isticmaalo, nooca calcium titanium waa in la qalajiyey by 150 ℃ 1 saac, hoose A nooca hydrogen waa in la qalajiyo 200-250 ℃ 1 saac (ma soo noqnoqda qalajin, haddii kale daahan waa sahlan tahay in dildilaac iyo jajab), si looga hortago in daahan electrode stick saliid iyo wasakh kale, si aanay u kordhin content carbon ee tollayn alxanka iyo saamayn tayada qaybaha alxanka.

3.garabalxanka tuubooyinka, by kululaynta soo noqnoqda roobab carbide, yaraynaysaa caabbinta daxalka iyo sifooyinka farsamada.
4. chromegarabQalabyada alxanka ka dib adkaynta flange heerka Maraykanku waa weyn yahay, fududahay in la dillaaco. Haddii nooc isku mid ah ee chromium ahama electrode (G202, G207) alxanka, waa in la sameeyaa in ka badan 300 ℃ preheating iyo ku saabsan 700 ℃ ka dib alxanka daawaynta qaboojin gaabis ah. Haddii alxanka aan la daweyn karin alxanka ka dib, korantada tuubada flanged (A107, A207) waa in la isticmaalaa.
5.garab, si loo hagaajiyo caabbinta daxalka iyo alxanka iyo kordhinta qaddarka ku habboon ee walxaha xasiloonida Ti, Nb, Mo, iwm, alxanka ayaa ka fiican flange chrome. Marka la isticmaalayo nooc la mid ah chromium flange electrode (G302, G307), waa in preheated kor 200 ℃ iyo xanaaqa ka dib alxanka ku saabsan 800 ℃. Haddii alxanka aan la daweyn karin kulaylka, korantada alxanka tuubada flanged (A107, A207) waa in la isticmaalaa.
6.Carrarayxirmooyinka tuubooyinka, alxanka badhankagarabElektroodhku wuxuu leeyahay iska caabin daxalka wanaagsan iyo iska caabinta oksaydhka, oo si ballaaran loogu isticmaalo kiimikaad, bacriminta kiimikada, batroolka, soosaarka mishiinnada caafimaadka.
