Flat Welding Flange
Chifukwa flange ali ndi ntchito yabwino mabuku, chimagwiritsidwa ntchito ntchito zofunika monga makampani mankhwala, zomangamanga, madzi, ngalande, mafuta, kuwala ndi katundu mafakitale, refrigeration, ukhondo, mapaipi, kumenyana moto, mphamvu yamagetsi, Azamlengalenga, shipbuilding ndi zina zotero.
International chitoliro flange mfundo makamaka ndi machitidwe awiri, ndicho European chitoliro flange dongosolo akuimiridwa ndi German DIN (kuphatikiza kale Soviet Union) ndi American chitoliro flange dongosolo akuimiridwa ndi American ANSI chitoliro flanges.Kuphatikiza apo, pali ma flange a chitoliro cha Japan JIS, koma nthawi zambiri amagwiritsidwa ntchito pagulu m'mafakitale a petrochemical, ndipo alibe mphamvu zambiri padziko lonse lapansi.Tsopano kumayambiriro kwa flanges chitoliro m'mayiko osiyanasiyana ndi motere:
1. European system mapaipi flanges akuimiridwa ndi Germany ndi Soviet Union wakale
2. American dongosolo chitoliro flange miyezo, woimiridwa ndi ANSI B16.5 ndi ANSI B 16.47
3. British ndi French chitoliro flange miyezo, aliyense amene ali ndi mfundo ziwiri casing flange.
Mwachidule, miyezo yapadziko lonse lapansi yapadziko lonse lapansi imatha kufotokozedwa mwachidule ngati machitidwe awiri osiyana komanso osasinthika a chitoliro cha chitoliro: imodzi ndi dongosolo la European pipe flange lomwe likuimiridwa ndi Germany;winayo akuimiridwa ndi United States American pipe flange system.
IOS7005-1 ndi muyezo womwe unalengezedwa ndi International Organisation for Standardization mu 1992. Mulingo uwu kwenikweni ndi mulingo wa chitoliro womwe umaphatikiza mitundu iwiri ya mipope yochokera ku United States ndi Germany.
