Iiflangengamalungu amile kwidiskhi asetyenziswa kakhulu ekubhobhozeni.Iiflangezisetyenziswa ngababini kunye nokuhambelanaiiflangekwiivalvu. Kwimibhobho yobunjineli,iiflangezisetyenziselwa ikakhulu ukudityaniswa kwemibhobho. Kwisidingo sokudibanisa umbhobho, zonke iintlobo zofakelo lwe-flange, umbhobho ophantsi woxinzelelo unokusebenzisa ucingoiflange, ukusetyenziswa kwe-welding flange ngaphezu kwe-4 kilograms yoxinzelelo. Yongeza i-gasket yokutywina phakathi kweebiniiiflange, uze uqinise ngebholithi.Iiflangekunye noxinzelelo oluhlukeneyo lunobunzima obuhlukeneyo kwaye sebenzisa iibholithi ezahlukeneyo.

Xa kuthelekiswa nentsimbi yekhabhoni, insimbi engenasici inezi mpawu zilandelayo:
1) izinga eliphezulu elibi lombane, malunga namaxesha angama-5 e-carbon steel.
I-2) I-coefficient yokwandiswa komgca omkhulu, i-40% inkulu kune-carbon steel, kunye nokunyuka kweqondo lokushisa, i-coefficient yokwandiswa komgca wexabiso nayo inyuka ngokufanelekileyo.
3) I-conductivity ephantsi ye-thermal, malunga ne-1/3 ye-carbon steel.
Phawula:
1. Ukuze uthintele ukubola phakathi kwamehlo ngenxa yokufudumeza kwe-flange cover, i-welding current ayifanele ibe nkulu kakhulu, malunga ne-20% ngaphantsi kwe-carbon steel electrode, i-arc ayifanele ibe yinde kakhulu, ukupholisa ngokukhawuleza. phakathi kwamaleko, kunye ne-weld bead emxinwa ifanelekile.
2. i-electrode kufuneka igcinwe yomile xa isetyenzisiwe, uhlobo lwe-titanium calcium kufuneka lomiswe nge-150 ℃ ngeyure eli-1, uhlobo oluphantsi lwe-Hydrogen lufanele lomiswe nge-200-250 ℃ ngeyure eyi-1 (ungaphindi ukomiswe, ngaphandle koko ukugquma kulula i-crack kunye ne-flake), ukukhusela i-electrode yokugqoka i-oyile yentonga kunye nolunye ukungcola, ukuze unganyusi umxholo wekhabhoni we-welding seam kwaye uchaphazele umgangatho wamacandelo e-welding.

3.iflangeumbhobho welding, ngokuphindaphindiweyo ukufudumeza carbide precipitation, ukunciphisa ukumelana nokugqwala kunye neempawu mechanical.
4. ichromeiflangeizinto zokufakwa emva kokuwelda ukuqina kweflange esemgangathweni yaseMelika inkulu, kulula ukuyiqhekeza. Ukuba uhlobo olufanayo lwe-electrode yensimbi engenasici yechromium (G202, G207) kufuneka iqhutywe ngaphezulu kwe-300 ℃ yokufudumeza kwangaphambili kwaye malunga ne-700 ℃ emva kokuwelda unyango olucothayo lokupholisa. Ukuba i-weldment ayikwazi ukunyangwa emva kwe-welding, i-electrode yepayipi ene-flanged (A107, A207) iya kusetyenziswa.
5.iflange, ukwenzela ukuba kuphuculwe ukuxhathisa kwe-corrosion kunye ne-weldability kunye nokwandisa ubungakanani obufanelekileyo bezinto zokuzinza i-Ti, Nb, Mo, njl., i-weldability ingcono kune-chrome flange. Xa usebenzisa uhlobo olufanayo lwe-electrode ye-chromium flange (G302, G307), kufuneka ifudunyezwe ngaphezulu kwe-200℃ kwaye ishushu emva kwe-welding emalunga ne-800℃. Ukuba i-weldment ayikwazi ukuphathwa ngobushushu, i-electrode ye-welding pipe (A107, A207) kufuneka isetyenziswe.
6.Flangedizixhobo zombhobho, iqhosha-weldingiflangeI-electrode inokumelana ne-corrosion elungileyo kunye nokumelana ne-oxidation, isetyenziswa kakhulu kwimichiza, isichumisi sekhemikhali, i-petroleum, ukwenziwa koomatshini bezonyango.
