Izindinganiso zamazwe ngamazwe ze-flange zamapayipi ikakhulukazi zinezinhlelo ezimbili, okuyisistimu yamapayipi e-European flange emelwe i-DIN yaseJalimane (kuhlanganise ne-Soviet Union yangaphambili) kanye nesistimu ye-flange yamapayipi aseMelika emelwe amapayipi amapayipi e-ANSI aseMelika.Ngaphezu kwalokho, kukhona ama-flange amapayipi e-JIS aseJapane, kodwa ngokuvamile asetshenziswa kuphela emisebenzini yomphakathi ezitshalweni ze-petrochemical, futhi anomthelela omncane wamazwe ngamazwe.Manje ukwethulwa kwamapayipi amapayipi emazweni ahlukahlukene kanje:
1. Ama-flange amapayipi esistimu yaseYurophu amelwe iJalimane kanye nezwe elaliyiSoviet Union
2. Amazinga we-American pipe flange, amelwe i-ANSI B16.5 ne-ANSI B 16.47
3. Izindinganiso ze-pipe flange zaseBrithani nezaseFrance, izwe ngalinye kulawa womabili linezindinganiso ezimbili ze-casing flange.
Kafushane, izindinganiso ze-flange zamapayipi zomhlaba jikelele zingafingqwa njengezinhlelo ezimbili ze-flange zamapayipi ezihlukene nezingaguquguquki: enye i-European pipe flange system emelwe yiJalimane;enye imelwe yi-United States American pipe flange system.
I-IOS7005-1 iyindinganiso eyamenyezelwa yi-International Organization for Standardization ngo-1992. Leli zinga empeleni liyindinganiso ye-pipe flange ehlanganisa uchungechunge olubili lwamapayipi amapayipi avela e-United States naseJalimane.
