Insimbi engagqwaliflat welded flangeizinsimbi eziseceleni zenziwe ngokwezifiso. I-fixture kufanele iqale ifinyelele lapho kuvuza khona. Iphuzu ukusungula igumbi elivaliwe phakathi kwe-stainlessinsimbi flangeyomzimba kanye nelunga lepayipi. Ukuvimbela ukuvuza phakathi komzimba kanye ne-stainlessinsimbi flangengenxa yokugcinwa kwengcindezi, i-annular cavity inikezwa lapho i-clamp kanye nomphetho wangaphandle we-stainlessinsimbi flangeukunqwabelana komzimba. I-tooth clamp isetshenziswa njengethuluzi lokuvimbela ngoba i-clamp ku-flange encane yensimbi engagqwali engasuswa kalula ihanjiswe kububanzi obuncane obungenasici.insimbi flangengesikhathi sokujova. Ngemuva kokuthi i-sealant iqine ngesikhathi sokusebenza, hlola ukukhululeka kwengcindezi futhi wenze ukujova kwendawo ukuze uvale imbobo yomjovo.

Izinyathelo zokufaka i-Stainless steel flat welding flange:
1. Welding wamanje akufanele kube mkhulu kakhulu, mayelana 20% ezincane kuka carbon steel electrode, arc ayikwazi ukuba yinde kakhulu, inter-ungqimba Ukupholisa ayikwazi ukuvimbela ukushisa flange cover ukugqwala kumele kube fast.
2. I-electrode kumele yomiswe ngaphambi kokusetshenziswa. Uhlobo lwe-Perovskite kufanele lomiswe ku-150 ° C ihora elingu-1 futhi uhlobo oluphansi lwe-hydrogen kufanele lomiswe ku-200-250 ° C ihora elingu-1 (ungaphindi ukomisa ngaphezu kwesisodwa. Ungafaki i-welding, i-welding carbon content ukuvimbela ukunamathela kwe-electrode coating. emafutheni nokunye ukungcola, ukuze kungathinti izinga lezingxenye.
3. welding steel stainless flangeukufakwa kwamapayipi, ngenxa yokushisa okuphindaphindiwe nokumelana nokugqwala, imvula ye-carbide kanye nezakhiwo zemishini.
4. Ngemva kokushisela, i-i-flangeyokufakwa kwe-CHROMIUM yensimbi engenasici eqinile inkulu futhi kulula ukuqhekeka. Izinhlobo ezifanayo zama-electrode ensimbi engagqwali ye-chrome (G202, uma kusetshenziswa i-G207) kumele zishiswe kuqala zibe ngu-300°C noma ngaphezulu ngemva kokushisela futhi zipholiswe kancane kancane zibe ngu-700°C ngemva kokushisela. Uma ukwelashwa kokushisa kwe-weld kungenakwenzeka, izinduku (A107, A207) kufanele zisetshenziselwe ukushisela ama-flange ensimbi engagqwali.
5. engenasiciinsimbi flange, inani elifanele lezakhi ezizinzile i-Ti, Nb, Mo, njll., ukuze kuthuthukiswe ukumelana nokugqwala nokushisela, ukushisela kungcono kune-chromium insimbi engagqwali flange, uma usebenzisa uhlobo olufanayo lwe-chromium insimbi engagqwali flange electrode (G302, G307 ), yishise ifike ku-200°C noma ngaphezulu, futhi ngemva kokushisela ifike ku-800°C. Uma kungenjalo, yisebenzise.
6. insimbi engagqwali flanged tube electrode (A107, A207), engagqwaliinsimbi flangedukufakwa kwe-tube, i-welding flange electrode inokumelana nokugqwala okuhle kakhulu futhi ukumelana ne-oxidation kusetshenziswa kabanzi ekukhiqizeni amakhemikhali, umanyolo, uphethiloli, imishini yezokwelapha.
