ASME B16.5 yog dab tsi thiab vim li cas peb thiaj yuav tsum ua raws li tus qauv no?

\”AMSE B16.5\" qhov tseeb yog hais txog tus qauv flange yeeb nkab kev lag luam uas tau tsim thiab tswj hwm los ntawm American Society of Mechanical Engineers (ASME), thiab nws yog tus qauv sawv cev tseem ceeb ntawm \"American Pipe Flange System\". Feem ntau, ASME B16.5 siv tau rau cov yeeb nkab nrog NPS ntawm 24 nti thiab qis dua; rau cov kab uas hla loj dua (NPS 26 txog 60 nti), tus qauv ASME B16.47 yuav tsum tau siv.

• Cov hom flange uas muaj kev npog:suav nrog cov flanges butt-weld, socket-weld flanges, threaded flanges, slip-on flanges, lap-joint flanges, thiab blind flanges, thiab lwm yam.

Qhov no yog ib qho ntawm cov qauv siv dav tshaj plaws rau cov yeeb nkab flanges thiab cov khoom flange hauv kev lag luam petrochemical thoob ntiaj teb, tshuaj lom neeg, fais fab, roj thiab roj av.

Lub ntsiab lus tseem ceeb thiab daim ntawv thov ntawm tus qauv

Tus qauv ASME B16.5, uas raug hu ua "NPS 1/2 rau NPS 24 Metric / American Standard Pipe Flanges thiab Flange Fittings", feem ntau hais tias:

• Qhov loj me:Npog cov flanges nrog cov yeeb nkab nominal diameters (NPS) txij li 1/2 nti txog 24 nti.
• Kev ntsuas siab:Txhais xya chav kawm siab (Chav Kawm) ntawm 150, 300, 400, 600, 900, 1500 thiab 2500. Txhua chav kawm sib raug rau qhov siab tshaj plaws ntawm kev ua haujlwm siab thiab kev hloov pauv nrog qhov kub thiab txias.
• Cov ntsiab lus ntawm cov lus qhia:Qhia meej txog qhov ntsuas siab-kub, cov ntaub ntawv, qhov loj me, kev kam rau siab, cov cim thiab kev ntsuam xyuas uas xav tau rau cov flanges.
