ʻO ka paipu honuaflangeʻO ka maʻamau he ʻelua ʻōnaehana, ʻo ia ka paipu ʻEulopaʻōnaehana flangehōʻike ʻia e ka German DIN (me ka Soviet Union mua) a me ka paipu ʻAmelikaʻōnaehana flangehōʻike ʻia e ka paipu ANSI ʻAmelikaflange.Eia kekahi, aia nā paipu JIS Iapananā lehelehe, akā, i loko o nā hoʻonohonoho petrochemical maʻamau e hoʻohana wale ʻia no nā hana lehulehu, a liʻiliʻi ka hopena honua.Hoʻokomo ʻia nā flanges paipu o nā ʻāina like ʻole ma lalo nei:

1, iā Kelemānia a me ka Soviet Union mua ma ke ʻano he ʻelele o ka paipu ʻōnaehana ʻEulopaflange
2. ʻO ka maʻamau flange paipu pūnaewele ʻAmelika, hōʻike ʻia e ANSIB16.5 a me ANSIB16.47
3, Pelekania a me Palani paipu flange standards, elua aina i elua paipu flange hae.
ʻO ka hōʻuluʻulu ʻana, hiki ke hōʻuluʻulu ʻia ke kūlana honua o nā flanges paipu i ʻelua ʻōnaehana flange pipe ʻokoʻa a ʻaʻole hoʻololi ʻia: kahi ʻōnaehana pipe flange ʻEulopa i hōʻike ʻia e Kelemania;ʻO kekahi ʻo ka ʻōnaehana flange paipu ʻAmelika i hōʻike ʻia e ʻAmelika Hui Pū ʻIa.
ʻO Ios7005-1 kahi maʻamau i hoʻolaha ʻia e ka International Organization for Standardization i ka makahiki 1992, ʻo ka maʻamau ʻo ʻAmelika Hui Pū ʻIa a me Kelemānia ʻelua pūʻulu o nā flanges paipu i hoʻohui ʻia i ka standard flange pipe.
