1. Ukuwelda okucaba: kuphela ukuwelda umaleko wangaphandle, akufuneki ukuba udibanise umaleko wangaphakathi; Ngokuqhelekileyo isetyenziswe kwimibhobho yoxinzelelo oluphakathi kunye noluphantsi, uxinzelelo lwegama lofakelo lwemibhobho kufuneka lube ngaphantsi kwe-2.5mpa. Zintathu iindidi zokutywinwa komphezulu weflange welding ethe tyaba, ngohlobo olugudileyo ngokulandelelana, uhlobo lweconcave kunye neconvex kunye nohlobo lwe-tenon groove, olusetyenziswa ngokubanzi kuhlobo olugudileyo, kwaye luyafikeleleka, lungabizi kakhulu.
2. Ukuwelda kwempundu:umaleko wangaphakathi nangaphandle weiflangekufuneka idityaniswe. Ngokuqhelekileyo isetyenziselwa imibhobho yoxinzelelo oluphakathi kunye nophezulu, kwaye uxinzelelo lwegama lombhobho luphakathi kwe-0.25 kunye ne-2.5MPa. Umphezulu wokutywina we-butt welding flange uqhagamshelo yi-concave-convex, ukufakela kunzima kakhulu, ngoko iindleko zabasebenzi, indlela yokufakela kunye neendleko zempahla ezincedisayo ziphezulu kakhulu.
3. I-socket welding: isetyenziswa ngokubanzi kwimibhobho enoxinzelelo lwegama elingaphantsi okanye elilingana ne-10.0mpa kunye nedayamitha yegama elingaphantsi okanye elilingana ne-40mm.
4. Umkhono okhululekileyo: ngokuqhelekileyo isetyenziselwa uxinzelelo alukho phezulu kodwa i-medium iyonakali ngakumbi kumbhobho, ngoko ke olu hlobo lwe-flange lunokumelana okuqinileyo kwe-corrosion, izinto eziphathekayo ziyintsimbi engenasici.

Olu hlobo loqhagamshelwano lusetyenziselwa ikakhulu ukudityaniswa kombhobho wentsimbi, umbhobho womgca werabha, umbhobho wentsimbi ongeyontsimbi kunye nevalve yeflange, njl.iflangeuqhagamshelwano.
Inkqubo yokudibanisa iFlange ngolu hlobo lulandelayo: Uqhagamshelo lweFlange kunye nombhobho kufuneka luhlangabezane nezi mfuno zilandelayo:
1. Iziko lombhobho kunyeiflangekufuneka ibe kumgangatho ofanayo.
2. Umphezulu wokutywina weziko lombhobho kunye ne-flange yi-90 degrees vertical.
3. Isikhundla seiflangeiibholiti kumbhobho kufuneka zihambelane.
