ANSI B16.5 ndi muyezo wofalitsidwa ndi American National Standards Institute (ANSI) wotchedwa "Chitoliro chachitsuloZojambula za Flanges ndi Flanges- Pressure Classes 150, 300, 400, 600, 900, 1500, 2500 "(Pipe Flanges ndi Flanged Fittings NPS 1/2 kupyolera mu NPS 24 Metric/Inch Standard).
Muyezowu umatchulanso zofunikira pamiyeso, kukakamiza, zida ndi mayeso azitsulo zamapaipi achitsulo ndi zolumikizira zofananira zolumikizirana ndi kuphatikizira mapaipi.
Flanges wamba pogwiritsa ntchito muyezo uwu ndi: kuwotcherera khosi flange, kuterera pa flange hubbed, mbale lathyathyathya kuwotcherera flange, akhungu flange,zitsulo zowotcherera flange, ulusi wa flange,nangula flangendiflange yomasuka.
Muyezo wa ANSI B16.5 ndi umodzi mwamiyezo yomwe imagwiritsidwa ntchito kwambiri pakupanga mapaipi.Imatchula ma flange okhala ndi milingo yosiyanasiyana yokakamiza kuti akwaniritse ntchito zosiyanasiyana komanso zofunikira.Flanges izi angagwiritsidwe ntchito kulumikiza mapaipi, mavavu, zida ndi zigawo zina m'madera osiyanasiyana mafakitale, kuphatikizapo mafuta, mankhwala, gasi, mphamvu yamagetsi, etc.
Zambiri ndi mawonekedwe ake:
1.Kukula kosiyanasiyana: ANSI B16.5 muyezo umatanthawuza kukula kwa zitsulo zazitsulo zazitsulo, zomwe zimaphimba 1/2 inch (15mm) mpaka 24 mainchesi (600mm), komanso zimaphatikizapo kuthamanga mwadzina kuchokera ku 150 psi (PN20) mpaka 2500 psi (PN420) kupsinjika maganizo.
2.Mulingo wa Pressure: Muyezo umatanthawuza ma flange okhala ndi miyeso yosiyana ya kuthamanga, yomwe imagwirizana ndi kuthamanga kwa ntchito komanso kutentha.Kupanikizika kofala kumaphatikizapo 150, 300, 600, 900, 1500, ndi 2500, pakati pa ena.
3.Zofunikira zakuthupi: Muyezo umanena za kapangidwe kake ka mankhwala, makina opangira zinthu komanso zofunikira pakupanga zinthu zopangidwa ndi flanges, kuphatikiza chitsulo cha kaboni, chitsulo chosapanga dzimbiri, chitsulo cha alloy, etc.
4.Zofunikira pakupanga: Muyezo umatanthawuza zofunikira za mapangidwe a flange, monga makulidwe a flange, chiwerengero ndi m'mimba mwake wa mabowo olumikiza bolt, etc.
5.Kuyesa: Muyezo umafuna kuti ma flanges ayesedwe mosiyanasiyana panthawi yopanga kuti atsimikizire kuti akukwaniritsa zofunikira ndikuwonetsetsa chitetezo ndi kudalirika kwa kulumikizana.
Zomwe zili mulingo wa ANSI B16.5 ndizokwanira.Amapereka chitsogozo chofunikira komanso zofunikira kwa mainjiniya, opanga ndi opanga kuti awonetsetse kuti kulumikizana ndi kuphatikizira kwamapaipi kumakwaniritsa miyezo ndi zofunikira.Muzogwiritsa ntchito, mtundu woyenera wa flange ndi mawonekedwe ake ayenera kusankhidwa molingana ndi zofunikira zaumisiri ndi mapangidwe ake kuti zitsimikizire kuti mapaipi amayenda bwino.
