Loaʻa i nā kūlana flange paipu honua ʻelua ʻōnaehana, ʻo ia ka ʻōnaehana pipe flange ʻEulopa i hōʻike ʻia e German DIN (me ka Soviet Union mua) a me ka ʻōnaehana pipe flange ʻAmelika i hōʻike ʻia e nā flanges paipu ANSI ʻAmelika.Eia kekahi, aia nā flanges paipu JIS Iapana, akā hoʻohana wale ʻia lākou i nā hana lehulehu i nā mea kanu petrochemical, a he liʻiliʻi ko lākou hopena honua.I kēia manawa ka hoʻolauna ʻana o nā flanges paipu ma nā ʻāina like ʻole penei:

1. ʻO nā flanges paipu ʻEulopa i hōʻike ʻia e Kelemania a me ka Soviet Union mua
2. Nā kūlana flange paipu pūnaewele ʻAmelika, hōʻike ʻia e ANSI B16.5 a me ANSI B 16.47
3. ʻO nā kūlana flange paipu Pelekāne a me Palani, aia i kēlā me kēia o nā ʻāina ʻelua ʻelua mau kūlana flange casing.

I ka hōʻuluʻulu manaʻo, hiki ke hōʻuluʻulu ʻia nā kūlana flange paipu honua honua ma ke ʻano he ʻelua ʻōnaehana flange paipu like ʻole a hiki ʻole ke hoʻololi ʻia: hoʻokahi ka ʻōnaehana pipe flange ʻEulopa i hōʻike ʻia e Kelemania;ʻo kekahi e hōʻike ʻia e ka ʻōnaehana flange paipu ʻAmelika Hui Pū ʻIa.

ʻO IOS7005-1 kahi maʻamau i hoʻolaha ʻia e ka International Organization for Standardization i ka makahiki 1992. ʻO kēia maʻamau he maʻamau flange paipu e hui pū ana i ʻelua pūʻulu o nā flanges paipu mai ʻAmelika Hui Pū ʻIa a me Kelemānia.
