ʻO ka ʻōnaehana flange paipu ʻEulopa, ʻo ia hoʻi ka Soviet Union mua, ua hōʻike ʻia e ka German DIN, a ʻo ka ʻōnaehana pipe flange ʻAmelika e hōʻike ʻia e ka flange paipu ANSI ʻAmelika.ʻO kēia mau kūlana ʻelua ka mea nui i hoʻohana ʻia ma ka honua.He koho ʻē aʻe nā ʻūhā paipu JIS Iapana, ʻoiai ua hoʻemi ʻia ko lākou mana honua no ka mea maʻamau e hoʻohana wale ʻia lākou no nā hana lehulehu ma nā wahi petrochemical.Eia ka ʻike maʻamau o nā flanges paipu i hoʻohana ʻia i kēlā me kēia lāhui:
1. ʻO Kelemānia a me ka Soviet Union mua nā lālā ʻelua o ka ʻōnaehana ʻEulopa.
2. ʻO ka ANSI B16.5 a me ANSI B 16.47 American system pipe flange standards
3. Aia nā kūlana flange casing kaʻawale no nā ʻāpana paipu paʻa o nā ʻāina ʻelua.
I ka hopena, ʻo nā ʻōnaehana flange paipu ʻokoʻa ʻelua a hiki ʻole ke hoʻololi i ka pae honua holoʻokoʻa o nā flanges paipu penei: kahi ʻōnaehana paipu ʻEulopa, i hōʻike ʻia e Kelemania;a he ʻōnaehana flange paipu ʻAmelika, i hōʻike ʻia e ʻAmelika Hui Pū ʻIa.
Ua hoʻopuka ka International Organization for Standardization i ka standard flange pipe i kapa ʻia ʻo IOS7005-1 i ka makahiki 1992. Hoʻohui kēia maʻamau i nā kūlana flange pipe mai Kelemānia a me ʻAmelika Hui Pū ʻIa.
