ANSI B16.47 Series A flange ndi mtundu wa flange wopangidwa kuti ugwirizane ndi kuthamanga kwambiri komanso kukula kwake kwakukulu poyerekeza ndi ANSI B16.5 muyezo. Bungwe la American National Standards Institute (ANSI) B16.47 Series A limatchula miyeso, mawonekedwe azinthu, ndi zofunikira zoyezetsa ma flanges akulu akulu omwe amagwiritsidwa ntchito popanikiza kwambiri.
Ma Flanges a Series A amagwiritsidwa ntchito m'mafakitale monga mafuta ndi gasi, petrochemical, ndi kupanga magetsi, komwe kupanikizika kwambiri ndi kutentha kumakhala kofala. Ma flanges awa amapezeka kukula kwake kuyambira mainchesi 26 mpaka 60 mainchesi ndipo adapangidwa kuti akwaniritse zofunikira zamapaipi akuluakulu amakampani.
ANSI B16.47 Series A flange imakhala ndi nkhope yokwezeka komanso bwalo lalikulu la bolt, zomwe zimapereka kulumikizana kotetezeka komanso kodalirika pamapulogalamu olemetsa. Ma flanges awa amapezeka muzinthu zosiyanasiyana, monga chitsulo cha carbon, chitsulo chosapanga dzimbiri, ndi zitsulo za alloy, kuti zigwirizane ndi ntchito zosiyanasiyana.
Mbali imodzi yofunika kwambiri ya Series A flange ndi nkhope yake yayikulu ya flange ndi bwalo lozungulira la bawuti, zomwe zimalola kuti pakhale bawuti yapamwamba komanso kugawa bwino kupsinjika, zomwe zimapangitsa kuti kusindikiza kukhale bwino komanso kuchepetsa chiopsezo cha kutayikira.
Mwachidule, ANSI B16.47 Series A flange ndi chisankho cholimba komanso chodalirika pamapaipi opopera othamanga kwambiri komanso akulu akulu, omwe amapereka magwiridwe antchito apamwamba komanso olimba pakugwiritsa ntchito mafakitale.
