Zvinhu zvina zvinobataflange processvari:
1. Annealing tembiricha inosvika tembiricha yakatarwa. Flange processing inowanzogamuchirwa mhinduro yekupisa kurapwa, tembiricha ye1040 ~ 1120 ℃ (yeJapan chiyero). Iwe unogona zvakare kuona kuburikidza neannealing cheto chekutarisa gomba, iyo flange iri munzvimbo yeannealing inofanirwa kuve incandescent, asi hapana kupfava kuderera.
2. Kuiswa chisimbiso chemuviri wechoto. Choto chinopfungaira chinopenya ngachive chakapoteredzwa choga choga kubva kunze kwemhepo; Nehaidhirojeni segasi rinorinda, mhepo imwe chete yakazaruka (kupisa iyo hydrogen inobuda). Iyo nzira yekuongorora inogona kushandiswa kupukuta mitswe yejoini yega yega muchoto chekupisa nesipo nemvura kuona kana mhepo inotiza; Pakati pavo, iyo yakanyanya nyore kumhanya mhepo ndiyo annealing choto mupombi uye kunze kwepombi nzvimbo, mhete yekuisa chisimbiso munzvimbo ino inonyanya kupfekwa, kazhinji kutarisa uye kazhinji kuchinja.

3. Chengetedza mhepo yemhepo. Kuti udzivise micro-leakage yepombi fittings, iyo inodzivirira gasi muchoto inofanira kuchengetedza imwe dzvinyiriro yakanaka. Kana iri hydrogen inodzivirira gasi, inowanzodiwa kuti ive pamusoro pe20kBar.
4. Anealing atmosphere. Kazhinji, haidhirojeni yakachena inoshandiswa semhepo yemhepo, uye kuchena kwemhepo kunodarika 99.99%. Kana chimwe chikamu chemumhepo chiri inert gasi, kuchena kunogonawo kuve kwakaderera, asi hakufanirwe kuve neokisijeni yakawandisa uye mhute yemvura.
