Izinto ezine ezichaphazela iinkqubo flangezezi:
1. Ubushushu be-anealing bufikelela kubushushu obuchaziweyo.Ukusetyenzwa kwe-Flange kwamkelwa ngokubanzi kunyango lobushushu lwesisombululo, uluhlu lobushushu lwe-1040 ~ 1120 ℃ (umgangatho waseJapan).Unokujonga kwakhona kumngxuma wokujonga isithando somlilo, i-flange kwindawo ye-anneal kufuneka ibe yi-incandescent, kodwa akukho ukuthomba kuthoba.
2. Ukutywinwa komzimba wesithando somlilo.Iziko lomlilo elikhanyayo liya kubiyelwa kwaye libe lodwa ngaphandle emoyeni;Nge-hydrogen njengegesi yokugada, inye kuphela i-vent evulekileyo (ukutshisa i-hydrogen ephumayo).Indlela yokuhlola ingasetyenziselwa ukusula iintanda zelungu ngalinye kwisithando somlilo ngesepha namanzi ukubona ukuba umoya uyabaleka;Phakathi kwabo, eyona nto ilula kakhulu ukuqhuba umoya sisithando somlilo kwipayipi kunye nokuphuma kwindawo yombhobho, ikhonkco lokutywina kule ndawo lilula kakhulu ukunxiba, lihlala lijonge kwaye lihlala litshintsha.

3. Khusela uxinzelelo lomoya.Ukuze kuthintelwe ukuvuza kwe-micro-leak of fittings pipe, igesi yokukhusela kwisithando somlilo kufuneka igcine uxinzelelo oluthile oluhle.Ukuba yigesi yokukhusela i-hydrogen, iyafuneka ngokubanzi ukuba ibe ngaphezu kwe-20kBar.
4. Umoya opholileyo.Ngokubanzi, i-hydrogen esulungekileyo isetyenziswa njenge-atmosfera yomoya, kwaye ukucoceka kwe-atmosfera kungaphezu kwama-99.99%.Ukuba enye indawo ye-atmosphere yi-inert gas, ukucoceka kunokuba ngaphantsi, kodwa akufanele kuqulethe i-oxygen eninzi kunye nomphunga wamanzi.
