Kodi ASME B16.5 ndi chiyani ndipo n’chifukwa chiyani tiyenera kutsatira muyezo umenewu?

"AMSE B16.5"" kwenikweni amatanthauza muyezo wa flange ya mapayipi a mafakitale wopangidwa ndi kusamalidwa ndi American Society of Mechanical Engineers (ASME), ndipo ndiye muyezo woyimira wa "American Pipe Flange System". Kawirikawiri, ASME B16.5 imagwiritsidwa ntchito pamapayipi okhala ndi NPS ya mainchesi 24 ndi pansi; pa mainchesi akuluakulu (NPS 26 mpaka 60 mainchesi), muyezo wa ASME B16.47 uyenera kugwiritsidwa ntchito.

• Mitundu ya flange yophimbidwa:kuphatikizapo ma flange a butt-weld, ma socket-weld flanges, ma threaded flanges, ma slip-on flanges, ma lap-joint flanges, ndi ma blind flanges, pakati pa ena.

Iyi ndi imodzi mwa miyezo yomwe imagwiritsidwa ntchito kwambiri pa ma flange a mapaipi ndi zigawo za flange m'mafakitale apadziko lonse lapansi a petrochemical, chemical, power, mafuta ndi gasi.

Tanthauzo lalikulu ndi momwe muyezowu umagwiritsidwira ntchito

Muyezo wa ASME B16.5, womwe umadziwika kuti \”NPS 1/2 to NPS 24 Metric/American Standard Pipe Flanges and Flange Fittings\”, makamaka umati:

• Kukula kwa mitundu:Imaphimba ma flange okhala ndi mainchesi a nominal pipe (NPS) kuyambira mainchesi 1/2 mpaka 24.
• Kuyeza kwa kuthamanga:Amatanthauzira magulu asanu ndi awiri a kuthamanga (Magulu) a 150, 300, 400, 600, 900, 1500 ndi 2500. Kalasi iliyonse imafanana ndi kuthamanga kosiyanasiyana kovomerezeka kogwira ntchito komanso kusintha kwa kutentha.
• Zomwe zili mu specification:Tsatanetsatane wa kuchuluka kwa kuthamanga ndi kutentha, zipangizo, miyeso, kulekerera, zizindikiro ndi mayeso ofunikira pa ma flange.

Gawo la 150Kupanikizika kwakukulu (100°F / 38°C): 285 psi Kugwiritsa ntchito: Mapaipi amadzi wamba, nthunzi yotsika, machitidwe a HVAC

Mndandanda wa 300Kupanikizika kwakukulu (100°F / 38°C): 740 psi Kugwiritsa ntchito: Nthunzi yapakati, madzi a mafakitale, kukonza mankhwala

Giredi ya 600Kupanikizika kwakukulu (pa 100°F / 38°C): 1480 psi Kugwiritsa ntchito: Mapaipi a nthunzi, mafuta ndi gasi, mafakitale oyeretsera zinthu

Kupanikizika kwa 900 psi ndi kupitirira apo(100°F / 38°C): 2200 psi ndi kupitirira apo. Ntchito: Makampani akuluakulu, malo opangira magetsi, nsanja za m'mphepete mwa nyanja, malo opangira magetsi a nyukiliya.
