1, i-butt welding flangeizinga lokushisa le-anneal lifinyelela ezingeni lokushisa elishiwo,i-butt welding flangeukwelashwa ngokuvamile kuthathwa ukwelashwa ukushisa isixazululo, okungukuthi, abantu ngokuvamile okuthiwa "annealing", izinga lokushisa 1040 ~ 1120 ℃. Ungabuka futhi ngembobo yokubuka isithando somlilo, ii-flangeizinto ezifakwa endaweni yokudoba kufanele zibe yi-incandescent, kodwa akukho ukuthambisa okuxegayo.
2, umoya oshisayo,i-butt welding flangengokuvamile isetshenziswa njengomkhathi ohlanzekile we-hydrogen annealing, ukuhlanzeka komkhathi kungaphezu kuka-99.99%, uma enye ingxenye yomkhathi iyigesi engasebenzi, ubumsulwa bungase bube ngaphansi kancane, kodwa bungakwazi ukuqukatha umoya-mpilo omningi, umhwamuko wamanzi. .

I-butt welding flange
3, i-butt welding flangeukuvikela ingcindezi yegesi, ukuze kuvikelwei-butt welding flangeUkuvuza, igesi yokuvikela isithando somlilo kufanele igcine ukucindezela okuthile okuhle, uma kuyigesi yokuvikela i-hydrogen, ngokuvamile idinga ngaphezu kuka-20kBar.
4, welding flangeukucubungula umhwamuko wamanzi esithandweni sokuphonsa, ngakolunye uhlangothi, hlola ukuthi impahla yesithando somlilo yomile yini, impahla yesithando somlilo kufanele yomiswe okokuqala; Okwesibili ukuthi ngabe ii-flangeukufakwa kwamapayipi esithandweni kuhlala kugcwele amanzi amaningi, ikakhulukazi uma kunezimbobo zokufakwa kwamapayipi e-flange, ungangeni, ngaphandle kwalokho umkhathi wesithando somlilo uzobhujiswa ngokuphelele.
5, i-butt welding flangeukufakwa uphawu komzimba ezithandweni,i-butt welding flangeisithando somlilo esikhanyayo kufanele sivalwe, sihlukaniswe nomoya wangaphandle; Nge-hydrogen njengegesi evikelayo, kuvulwe imbobo eyodwa kuphela. Indlela yokuhlola ingasetshenziswa ukusula imifantu yejoyinti ngalinye esithandweni somlilo ngensipho namanzi ukuze kubonakale ukuthi kuzogijima yini; Phakathi kwazo, indawo okulula ukugijima kuyo indawo lapho isithando somlilo singena epayipini nendawo lapho ipayipi iphuma khona. Indandatho yokuvala kule ndawo kulula kakhulu ukuyigqoka futhi idabuke, ngakho kufanele ihlolwe futhi ishintshwe njalo.
