Ipayipi lamazwe ngamazwei-flangeizinga ngokuyinhloko linezinhlelo ezimbili, okuyipayipi laseYurophuuhlelo lwe-flangeemelelwa yi-DIN yesiJalimane (kuhlanganise ne-Soviet Union yangaphambili) kanye nepayipi laseMelikauhlelo lwe-flangeemelelwa ipayipi le-ANSI laseMelikai-flange.Ngaphezu kwalokho, kukhona ipayipi Japanese JISama-flange, kodwa ekufakweni kwe-petrochemical ngokuvamile okusetshenziselwa imisebenzi yomphakathi kuphela, futhi umthelela wamazwe ngamazwe mncane.Amapayipi amapayipi amazwe ahlukahlukene ethulwa ngezansi:

1, eya eJalimane kanye ne-Soviet Union yangaphambili njengommeleli wepayipi lesistimu yaseYurophui-flange
2. Izinga lepayipi lepayipi lesistimu yaseMelika, elimelwe yi-ANSIB16.5 ne-ANSIB16.47
I-3, amazinga we-pipe flange aseBrithani naseFrance, amazwe amabili ngalinye linamazinga amabili e-pipe flange.
Ukufingqa, izinga lamazwe ngamazwe lama-flange amapayipi lingafingqwa njengezinhlelo ezimbili ze-pipe flange ezihlukene futhi ezingaguquguquki: i-European pipe flange system emelwe yiJalimane;Enye i-American pipe flange system emelwe yi-United States.
I-Ios7005-1 iyindinganiso eyamenyezelwa yi-International Organisation for Standardization ngo-1992, indinganiso empeleni i-United States neJalimane uchungechunge olubili lwamapayipi amapayipi ahlanganiswe ezingeni le-pipe flange.
