Kuthatha umsebenzi omningi ukwakha ama-flange wokushisela izinqe, futhi ngenxa yokuthi ama-flange amakhulu okushisela anezindleko eziphakeme kangaka zokukhiqiza, ukushisa kuqala kuyadingeka njalo. Ukuguqulwa kwezinto zokusetshenziswa kanye nenqubo yokuguqulwa okuhlobene nezinga lokushisa nezici zemishini zemodeli yezibalo kwaziwa ngokuthi i-computer simulation flange. Le nqubo yokuguquguquka yenziwa ngosizo lwe-computer simulation nganoma yisiphi isikhathi lapho isimo sokucindezeleka, ubunzima, kanye nokusatshalaliswa kwezinga lokushisa kukhona. Ukulingisa ngokomzimba okwenziwe ngekhompyutha kanye nokulingisa inqubo kungasekelana futhi kuthuthukise okunye. Ama-flange wokushisela izinqe asebenza kanzima ukuzenza, futhi ukushisa kuqala kuyadingeka ngenxa yezindleko eziphezulu zokwenza ama-flange amakhulu okushisela. I-Computer simulation flange igama elisetshenziswa ukuchaza ukuthi izinto ezingavuthiwe ziwohloka kanjani kanye nokuthi izinga lokushisa kanye nezakhiwo zemishini zemodeli yezibalo ziwohloka kanjani. Ukulingiswa kwekhompyutha kusetshenziselwa ukwenza le nqubo yokuguquguquka noma nini lapho izimo zengcindezi, ubunzima, kanye nokusabalalisa kwezinga lokushisa kuhlangatshezwana nazo. Ukulingisa inqubo yekhompuyutha nokulingisa ngokomzimba kungazuza kokubili futhi kuphelelisane.
I-European pipe flange system, ehlanganisa i-Soviet Union yangaphambili, imelwe yi-DIN yaseJalimane, futhi i-American pipe flange system imelwe yi-American ANSI pipe flange. Lawa mazinga amabili yiwona ayinhloko asetshenziswa emazweni omhlaba. Ama-Tube flange aseJapan e-JIS angenye inketho, nakuba umthelela wawo wamazwe ngamazwe uncipha ngoba ngokuvamile asetshenziselwa kuphela imisebenzi yomphakathi ezindaweni ze-petrochemical. Okulandelayo ukubuka konke okuyisisekelo kwamapayipi amapayipi asetshenziswa esizweni ngasinye:
1.IJalimane kanye nezwe elaliyiSoviet Union ngamalungu amabili ohlaka lohlelo lwaseYurophu.
2.Amazinga e-ANSI B16.5 kanye ne-ANSI B 16.47 ye-American pipe flange
3.Kunezindinganiso ezihlukene ze-casing flange zamapayipi ahlukene wamazwe amabili.
Ekuphetheni, ama-flange amapayipi amabili ahlukene futhi angaguquguquki enza izinga lomhlaba wonke lama-flange amapayipi alandelayo: i-European pipe flange system, emelwe yiJalimane; kanye nesistimu ye-pipe flange yaseMelika, emelwe yi-United States.
I-International Organization for Standardization yashicilela izinga le-pipe flange elaziwa nge-IOS7005-1 ngo-1992. Leli zinga lihlanganisa izindinganiso ze-pipe flange ezivela eJalimane nase-United States.
