1, butt welding flangeiqondo lobushushu le-annealing lifikelela kubushushu obuchaziweyo,butt welding flangeunyango luthathwa ngokubanzi unyango unyango ubushushu, oko kukuthi, abantu ngokuqhelekileyo ebizwa ngokuba "annealing", uluhlu lobushushu 1040 ~ 1120 ℃.Unokujonga kwakhona ngomngxuma wokujonga isithando somlilo, iiflangeUkufakwa kwindawo yokucoca kufuneka kube yi-incandescent, kodwa akukho ukuthambisa ukuthoba.
2, umoya opholileyo,butt welding flangengokuqhelekileyo isetyenziswa njengomoya ococekileyo we-hydrogen annealing, ukucoceka kwe-atmosfera kungaphezu kwama-99.99%, ukuba enye indawo ye-atmosfera yigesi engasebenziyo, ukucoceka kunokuba ngaphantsi kancinane, kodwa akunakuqulatha ioksijini eninzi, umphunga wamanzi. .

I-butt welding flange
3, butt welding flangeukukhusela uxinzelelo lwegesi, ukwenzela ukuthintelabutt welding flangeukuvuza, igesi yokukhusela isithando somlilo kufuneka igcine uxinzelelo oluthile oluhle, ukuba igesi yokukhusela i-hydrogen, ifuna ngokubanzi ngaphezu kwe-20kBar.
4, welding flangeukucubungula umphunga wamanzi kwisithando somlilo sokuphosa, kwelinye icala, khangela ukuba izinto zesithando somlilo zomile, izinto zokutshisa kufuneka zomiswe okokuqala;Okwesibini kukubaiflangeukufakwa kombhobho kwisithando somlilo kuhlala kuninzi kakhulu amabala amanzi, ngakumbi ukuba kukho imingxuma kwizixhobo zemibhobho yeflange, musa ukuvuza, ngaphandle koko umoya wesithando somlilo uya kutshatyalaliswa ngokupheleleyo.
5, butt welding flangeukutywinwa komzimba kwiziko,butt welding flangeisithando somlilo esikhanyayo kufuneka sivalwe, sihlukaniswe nomoya wangaphandle;Nge-hydrogen njengegesi ekhuselayo, inye kuphela i-vent evulekileyo.Indlela yokuhlola ingasetyenziselwa ukusula iintanda zelungu ngalinye kwisithando somlilo ngesepha kunye namanzi ukuze kubonwe ukuba kuqhutywe;Phakathi kwabo, indawo ekulula ukuyiqhuba yindawo apho isithando somlilo singena kumbhobho kunye nendawo apho umbhobho uphuma khona.Umsesane wokutywina kule ndawo ulula kakhulu ukunxiba kunye nokukrazula, ngoko kufuneka ujongwe kwaye utshintshwe rhoqo.
