Iyini i-ASME B16.5 futhi kungani kufanele silandele le ndinganiso?

""I-AMSE B16.5"empeleni ibhekisela endinganisweni ye-flange yamapayipi ezimboni eyakhiwa futhi yagcinwa yi-American Society of Mechanical Engineers (ASME), futhi iyindinganiso eyinhloko emele i-"American Pipe Flange System". Ngokuvamile, i-ASME B16.5 isebenza kumapayipi ane-NPS engamasentimitha angu-24 nangaphansi; kumadayamitha amakhulu (amasentimitha angu-26 kuya kwangu-60), indinganiso ye-ASME B16.47 idinga ukusetshenziswa.

• Izinhlobo ze-flange ezimboziwe:kufaka phakathi ama-flange e-butt-weld, ama-flange e-socket-weld, ama-flange anezintambo, ama-flange ashelelayo, ama-flange ahambisanayo, kanye nama-flange angaboni, phakathi kwezinye.

Lena enye yezindinganiso ezisetshenziswa kakhulu kuma-flange amapayipi kanye nezingxenye ze-flange embonini yomhlaba wonke ye-petrochemical, chemical, power, oil kanye negesi.

Incazelo eyinhloko kanye nobubanzi bokusetshenziswa kwale nqubo

Izinga le-ASME B16.5, elaziwa ngokusemthethweni ngokuthi ama-NPS 1/2 kuya ku-NPS 24 Metric/American Standard Pipe Flanges and Flange Fittings\", libeka kakhulu:

• Ububanzi bosayizi:Imboza ama-flange ane-nominal pipe diameters (NPS) asukela ku-1/2 intshi kuya ku-24 intshi.
• Isilinganiso sokucindezela:Ichaza izigaba eziyisikhombisa zokucindezela (Amakilasi) angu-150, 300, 400, 600, 900, 1500 kanye no-2500. Iklasi ngalinye lihambisana nezingcindezi zokusebenza ezihlukile ezivunyelwe kanye nezinguquko ngokushisa.
• Okuqukethwe okucacisiwe:Ichaza ngokuningiliziwe izilinganiso zokucindezela nokushisa, izinto zokwakha, ubukhulu, ukubekezelelana, izimpawu kanye nokuhlolwa okudingekayo kuma-flange.

Izinga le-150Ukucindezela okuphezulu (100°F / 38°C): 285 psi Ukusetshenziswa: Amapayipi amanzi ajwayelekile, umusi ophansi, izinhlelo ze-HVAC

Uchungechunge lwama-300Ukucindezela okuphezulu (100°F / 38°C): 740 psi Isicelo: Umusi ocindezelwe okuphakathi nendawo, ukuhlinzekwa kwamanzi ezimbonini, ukucubungula amakhemikhali

Ibanga lama-600Ukucindezela okuphezulu (ku-100°F / 38°C): 1480 psi Ukusetshenziswa: Amapayipi anomusi ophakeme, uwoyela negesi, izindawo zokuhluza

Isilinganiso sokucindezela esingu-900 psi nangaphezulu(100°F / 38°C): 2200 psi nangaphezulu. Izicelo: Imboni enzima, iziteshi zikagesi, amapulatifomu asogwini lolwandle, iziteshi zikagesi zenuzi.
