Ingqiniba Yensimbi Engagqwali
Izindinganiso ze-flange yamapayipi omhlaba wonke zinezinhlelo ezimbili, okungukuthi uhlelo lwe-flange yamapayipi aseYurophu olumelwe yi-DIN yaseJalimane (kufaka phakathi i-Soviet Union yangaphambili) kanye nohlelo lwe-flange yamapayipi aseMelika olumelwe yi-flange yamapayipi aseMelika e-ANSI. Ngaphezu kwalokho, kune-flange yamapayipi aseJapan e-JIS, kodwa ngokuvamile asetshenziswa emisebenzini yomphakathi kuphela ezitshalweni ze-petrochemical, futhi anomthelela omncane kakhulu emhlabeni jikelele. Manje ukwethulwa kwama-flange amapayipi emazweni ahlukahlukene kungokulandelayo:
1. Ama-flange ephayiphi yesistimu yaseYurophu amelwe yiJalimane kanye neSoviet Union yangaphambili
2. Izindinganiso ze-flange zamapayipi esistimu yaseMelika, ezimelelwa yi-ANSI B16.5 kanye ne-ANSI B 16.47
3. Izindinganiso zeflange yamapayipi aseBrithani nawaseFrance, izwe ngalinye lala mazwe amabili linezindinganiso ezimbili zeflange ezifakwe esikhaleni.
Ngamafuphi, izindinganiso ze-flange yamapayipi ezibanzi emhlabeni wonke zingafingqwa njengezinhlelo ezimbili ze-flange zamapayipi ezihlukile nezingashintshaniswa: eyodwa uhlelo lwe-flange lwamapayipi aseYurophu olumelwe yiJalimane; enye imelelwe uhlelo lwe-flange lwamapayipi aseMelika.
I-IOS7005-1 iyindinganiso eyamenyezelwa yi-International Organisation for Standardization ngo-1992. Lendinganiso empeleni iyindinganiso ye-flange yamapayipi ehlanganisa uchungechunge olubili lwama-flange amapayipi avela e-United States naseJalimane.
