1. Ukuwelda okucaba:kuphela ukuwelda umaleko wangaphandle, ngaphandle kwe-welding yangaphakathi;Ngokuqhelekileyo isetyenziswe kwimibhobho yoxinzelelo oluphakathi kunye noluphantsi, uxinzelelo lwegama lombhobho lungaphantsi kwe-0.25mpa.Kukho iintlobo ezintathu zokutywinwa komphezuluflat welding flange, eziluhlobo olugudileyo, uhlobo lweconcave kunye neconvex kunye nodidi lwe-tenon groove.Phakathi kwazo, uhlobo olugudileyo lolona lusetyenziswa kakhulu, kwaye ixabiso liyafikeleleka kwaye liyasebenza.
2. Ukuwelda iimpundu:zombini iileya zangaphakathi nangaphandle zeiflangekufuneka idityaniswe, isetyenziswe ngokubanzi kwimibhobho yoxinzelelo oluphakathi kunye nophezulu, kwaye uxinzelelo lwegama lombhobho luphakathi kwe-0.25 ~ 2.5mpa.Umphezulu wokutywina wewelding flangeuxhulumaniso luyi-concave kunye ne-convex, kwaye ukufakela kuyinkimbinkimbi, ngoko iindleko zabasebenzi, indlela yokufakela kunye neendleko zezinto ezincedisayo ziphezulu kakhulu.

3. I socket welding:esetyenziswa ngokubanzi kuxinzelelo oluqhelekileyo lungaphantsi okanye lulingana no-10.0MPa, idiameter yegama ingaphantsi okanye ilingana ne-40mm kumbhobho.
4. Umkhono okhululekileyo: Isetyenziswa ngokubanzi kwimibhobho enoxinzelelo oluphantsi kodwa iphakathi elonakalisayo, ngoko ke olu hlobo lweflange lunokumelana ne-corrosion eyomeleleyo, kwaye izinto eziphathekayo ziyintsimbi engenasici.
Olu hlobo loqhagamshelwano lusetyenziswa ikakhulu kuqhagamshelo lombhobho wentsimbi, umbhobho wentsimbi, umbhobho wentsimbi ongeyontsimbi kunyeivalve yeflange, njl., kunye nokudityaniswa kwezixhobo zenkqubo kunye ne-flange nazo zidibene ne-flange.
