Yenziwe ngentsimbi eshayinayoiflange edityanisiweyoizinto ezisecaleni zenziwe ngokwesiqhelo. Isixhobo kufuneka sifike kwindawo yokuvuza kuqala. Ingongoma kukuseka igumbi elivaliweyo phakathi kwe-stainlessintsimbi yentsimbiyomzimba kunye nomdibaniso wombhobho. Ukuthintela ukuvuza phakathi komzimba kunye ne-stainlessintsimbi yentsimbingenxa yokugcinwa koxinzelelo, i-annular cavity inikezelwa apho i-clamp kunye nomda wangaphandle we-stainless.intsimbi yentsimbiUkuhlangana komzimba. Isixhobo sokudibanisa izinyo sisetyenziswa njengesixhobo sokuthintela ngenxa yokuba ibamba kwiflange encinci yentsimbi engatyiwayo enobukhulu inokuhanjiswa ngokulula ukuya kwidayamitha encinci engenasila.intsimbi yentsimbingexesha lokutofa. Emva kokuba i-sealant iqinile ngexesha lokusebenza, khangela ukuphumla koxinzelelo kwaye wenze i-reinjection yendawo ukuvala i-port injection.

Intsimbi engenastainless flat welding flange amanyathelo ofakelo:
1. i-welding yangoku kufuneka ingabi nkulu kakhulu, malunga ne-20% encinci kune-carbon steel electrode, i-arc ayinakuba yinde kakhulu, i-inter-layer yokupholisa ayikwazi ukuthintela ukufudumeza kwe-flange cover corrosion kufuneka ikhawuleze.
2. I-electrode kufuneka yomiswe ngaphambi kokusetyenziswa. Uhlobo lwe-Perovskite kufuneka lomiswe kwi-150 ° C ngeyure ye-1 kwaye uhlobo oluphantsi lwe-hydrogen kufuneka lomiswe kwi-200-250 ° C ngeyure eli-1 (ungaphindi ukomisa ngaphezu kweyodwa. Musa ukongeza i-welding, i-welding i-carbon content ukukhusela i-electrode coating adhesion. kwioli kunye nolunye ukungcola, ukuze ungachaphazeli umgangatho wamalungu.
3. welding steel stainless flangeizixhobo zombhobho, ngenxa yokufudumeza ngokuphindaphindiweyo kunye nokuxhathisa ukubola, i-carbide precipitation kunye neempawu zomatshini.
4. Emva kwe-welding, iiflangeyokuqina kweCHROMIUM yentsimbi engenazifakelo yeflange inkulu kwaye kulula ukuyiqhekeza. Iindidi ezifanayo ze-electrodes zensimbi ezingenasici ze-chrome (G202, xa usebenzisa i-G207) kufuneka zifudumezwe ukuya kwi-300 ° C okanye ngaphezulu emva kwe-welding kwaye zipholile ngokuthe ngcembe ukuya kwi-700 ° C emva kwe-welding. Ukuba unyango olushushu lwe-weld alunakwenzeka, iintonga (A107, A207) kufuneka zisetyenziselwe ukudibanisa iiflange zensimbi ezingenasici.
5. engenabalaintsimbi yentsimbi, ubungakanani obuchanekileyo bezinto ezizinzileyo ze-Ti, Nb, Mo, njl., ukwenzela ukuba kuphuculwe ukuxhathisa kwe-corrosion kunye ne-weldability, i-weldability ingcono kune-chromium ye-flange yensimbi engenasici, xa usebenzisa uhlobo olufanayo lwe-chromium ye-stainless steel flange electrode (G302, G307) ), yifudumeze ukuya kuma-200 ° C okanye ngaphezulu, kwaye emva kwe-welding malunga ne-800 ° C yomsindo. Ukuba akunjalo, yisebenzise.
6. insimbi engenasici ene-flanged tube electrode (A107, A207), i-stainlessintsimbi flangedUkufakwa kwe-tube, i-electrode ye-welding flange inokumelana nokugqwesa okugqwesileyo kunye nokumelana ne-oxidation kusetyenziswa kakhulu kwimveliso yeekhemikhali, izichumisi, i-petroleum, oomatshini bezonyango.
