Umbhobho wamazwe ngamazweiflangeumgangatho ubukhulu becala uneenkqubo ezimbini, ezizezi umbhobho waseYurophuinkqubo yeflangeimelwe yi-DIN yesiJamani (kubandakanywa ne-Soviet Union yangaphambili) kunye nombhobho waseMelikainkqubo yeflangeimelwe ngumbhobho we-ANSI waseMelikaiflange.Ukongeza, kukho umbhobho we-JIS waseJapaniiflange, kodwa kufakelo lwepetrochemical olusetyenziswa ngokubanzi kuphela kwimisebenzi yoluntu, kwaye impembelelo yamazwe ngamazwe incinci.Iiflange zemibhobho yamazwe ahlukeneyo ziziswa ngezantsi:

1, ukuya eJamani kunye neSoviet Union yangaphambili njengommeli wombhobho wenkqubo yaseYurophuiflange
2. Umbhobho we-American pipe standard standard, emelwe yi-ANSIB16.5 kunye ne-ANSIB16.47
I-3, imigangatho ye-flange yombhobho waseBrithani kunye nesiFrentshi, amazwe amabini anemigangatho emibini ye-pipe flange.
Ukushwankathela, umgangatho wamazwe ngamazwe we-pipe flanges unokushwankathelwa njengeenkqubo ezimbini ezahlukeneyo kunye nezingatshintshiyo zeflange yombhobho: inkqubo ye-flange yombhobho yaseYurophu emelwe yiJamani;Enye yinkqubo yeflange yombhobho waseMelika emelwe yiUnited States.
Ios7005-1 ngumgangatho owabhengezwa nguMbutho waMazwe ngaMazwe wokuMiselwa koMgangatho ngo-1992, umgangatho ngokwenene yi-United States kunye neJamani uthotho lweeflange zemibhobho ezidityaniswe kumgangatho weflange wombhobho.
