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 ekrusayo, ngoko olu hlobo lweflange lunokumelana nokugqwala okuqinileyo, kwaye izinto eziphathekayo ziyintsimbi engenasici.
Olu hlobo loqhagamshelwano lusetyenziswa ikakhulu kuqhagamshelo lombhobho wentsimbi, umbhobho wentsimbi, umbhobho wentsimbi ongeyontsimbi kunye.ivalve yeflange, njl., kunye nokudityaniswa kwezixhobo zenkqubo kunye ne-flange nazo zidibene ne-flange.
