ASME B16.48 Spectacle Blind Flange Carbon Steel A515 Gr60 A105

Zogulitsa Zambiri

Chiyambi cha Zamalonda

ASME B16.48 ndi mulingo wakhungu wopangidwa ndi American Society of Mechanical Engineers (ASME), woyenera mitundu yosiyanasiyana yamapaipi.Pakati pawo, chiwonetsero chakhungu flange mu ASME B16.48 ndi mtundu wapadera wa akhungu flange.
Themawonekedwe akhungu flange, yomwe imatchedwanso octagon blind flange, imapangidwa ndi ma flange akhungu a octagon, omwe amamangiriridwa pamodzi ndi mabawuti ndi ma gaskets pakati.Kusiyanitsa pakati pa mawonekedwe akhungu akhungu ndi mitundu ina ya ma flanges akhungu ndikuti imatha kupereka kukana kwamphamvu kwambiri komanso kusindikiza, koyenera kumayendedwe osiyanasiyana amagetsi othamanga kwambiri komanso mapaipi amadzimadzi.
Kukula ndi kukakamiza
Malinga ndi muyezo wa ASME B16.48, kukula kwa mawonekedwe akhungu akhungu kumachokera ku 1/2 inchi mpaka 24 inchi, ndipo kupanikizika kumatha kufika ku Class 150 (PN20), Class 300 (PN50), Class 600 (PN100), ndi Kalasi 900 (PN150).
Kuchuluka kwa ntchito
ASME B16.48 mawonekedwe akhungundi mtundu wapadera wakhungu ntchito machitidwe mapaipi, makamaka ntchito unsembe, kukonza, ndi kuyezetsa mavavu, mapampu, zida, flanges, ndi zipangizo zina.
Makamaka, mawonekedwe akhungu a ASME B16.48 amagwiritsidwa ntchito pazinthu izi:
1. Kulumikizana kwa Flange: mbale iyi yakhungu imalumikizidwa ndi flange ndipo imatha kugwiritsidwa ntchito pokonza kapena kusintha zida zamapaipi.Itha kukhala ngati chinthu chosindikizira kwakanthawi kuti tipewe kutayikira kwamadzimadzi pokonza kapena kusintha zida.
2. Kuyika zida: mbale iyi yakhungu itha kugwiritsidwanso ntchito poyika zida zatsopano.Pakakhala palibe zida m'mapaipi koma zida ziyenera kuyikidwa, mbale yakhunguyi imatha kusindikiza mapaipi kwakanthawi mpaka kuyika zida kumalizidwa ndikulumikizidwa ndi mapaipi.
3. Kuyesa kukakamiza: mbale iyi yakhungu ingagwiritsidwenso ntchito poyesa kukakamiza kwa machitidwe a mapaipi.Musanayambe kuyesa kukakamiza pamapaipi, ndikofunikira kutseka ma valve onse ndikugwiritsa ntchito mbale yakhungu iyi kuti mukhazikitse njira yotsekeka pamapaipi kuti mupewe kutayikira mwangozi pakuyesa kukakamiza.
Mwachidule, ASME B16.48 spectacle blind ndi chowonjezera cha mapaipi ochita ntchito zambiri chomwe chimakhala ndi ntchito zambiri pakukonza mapaipi, kukhazikitsa zida, komanso kuyesa kukakamiza.
Ubwino ndi kuipa kwake
Ubwino wake ndi:
1. Kukanika kwamphamvu kwamphamvu: Poyerekeza ndi mitundu ina ya ma flanges akhungu, mawonekedwe akhungu akhungu amatha kupereka kukana kwamphamvu kwambiri ndipo ndi koyenera pamakina osiyanasiyana amagetsi othamanga kwambiri komanso mapaipi amadzimadzi.
2. Kusindikiza kwabwino: chifukwa amapangidwa ndi mbale ziwiri za octagon zakhungu, zomwe zimamangirizidwa pamodzi ndi ma bolts ndi ma gaskets pakati, mawonekedwe akhungu akhungu amakhala ndi ntchito yabwino yosindikiza ndipo amatha kuteteza bwino kutayikira ndi kuipitsa.
Zoyipa:
1. Mtengo wokwera: Poyerekeza ndi mitundu ina ya ma flanges akhungu, mtengo wa magalasi akhungu ndi okwera kwambiri.
2. Kuyika ndi kukonza ndizovuta kwambiri: Kuyika ndi kukonza mawonekedwe akhungu owonera kumafuna zida zambiri ndi ntchito, zomwe zimakhala zovuta.
Zonse,ASME B16.48 mawonekedwe akhungu flangendi mkulu-ntchitokhungu lakhunguoyenera machitidwe osiyanasiyana amagetsi othamanga kwambiri komanso mapaipi amadzimadzi, okhala ndi zabwino monga kukana kukakamiza komanso kusindikiza.
