Flange welding flat me ka ai
Ma muli o ka maikaʻi o ka hana piha o ka flange, hoʻohana nui ʻia ia i nā papahana kumu e like me ka ʻoihana kemika, ke kūkulu ʻana, ka lako wai, ka wai, ka ʻaila, ka māmā a me ka ʻoihana kaumaha, refrigeration, sanitation, plumbing, fire fighting, electric power, aerospace, shipbuilding and pela aku.
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 me ʻelua mau kūlana flange casing.
ʻO ka hōʻuluʻulu manaʻo, hiki ke hōʻuluʻulu ʻia nā kūlana flange paipu honua holoʻokoʻa 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 ʻano o nā flanges paipu mai ʻAmelika Hui Pū ʻIa a me Kelemānia.
