ASME B16.5 ke eng hona ke hobane'ng ha re lokela ho latela tekanyetso ena?

""AMSE B16.5"Ha e le hantle e bolela tekanyetso ea flange ea liphaephe tsa indasteri e entsoeng le ho hlokomeloa ke Mokhatlo oa Amerika oa Baenjiniere ba Mechanical (ASME), 'me ke tekanyetso ea mantlha ea moemeli oa "American Pipe Flange System". Ka kakaretso, ASME B16.5 e sebetsa ho liphaephe tse nang le NPS ea lisenthimithara tse 24 le ka tlase; bakeng sa bophara bo boholo (NPS ea lisenthimithara tse 26 ho isa ho tse 60), tekanyetso ea ASME B16.47 e hloka ho sebelisoa.

• Mefuta ea li-flange tse koahetsoeng:ho kenyeletsoa le di-flange tsa butt-weld, di-flange tsa socket-weld, di-flange tse nang le di-threaded, di-flange tse thellang, di-flange tse kopanang le mahlakore, le di-flange tse sa boneng, hara tse ding.

Ena ke e 'ngoe ea litekanyetso tse sebelisoang haholo bakeng sa liphaephe tsa liphaephe le likarolo tsa liphaephe indastering ea lefats'e ea petrochemical, chemical, power, oli le khase.

Tlhaloso ea mantlha le boholo ba ts'ebeliso ea tekanyetso

Tekanyetso ea ASME B16.5, e tsejoang ka molao e le "NPS 1/2 ho isa ho NPS 24 Metric/American Standard Pipe Flanges and Flange Fittings", haholo-holo e hlalosa:

• Mefuta ea boholo:E koahela li-flange tse nang le bophara ba liphaephe tse tloaelehileng (NPS) ho tloha ho 1/2 inch ho isa ho 24 inches.
• Tekanyetso ea khatello:E hlalosa lihlopha tse supileng tsa khatello (Lihlopha) tsa 150, 300, 400, 600, 900, 1500 le 2500. Sehlopha se seng le se seng se tsamaisana le likhatello tse fapaneng tse lumelletsoeng tsa ho sebetsa le liphetoho tse amanang le mocheso.
• Dikahare tse hlalosang:E hlalosa ka botlalo litekanyetso tsa khatello le mocheso, thepa, litekanyo, mamello, matšoao le liteko tse hlokahalang bakeng sa li-flange.

Boemo ba bo-150Khatello e phahameng ka ho fetisisa (100°F / 38°C): 285 psi Tšebeliso: Liphaephe tsa metsi tse akaretsang, mouoane o nang le khatello e tlase, litsamaiso tsa HVAC

Letoto la 300Khatello e phahameng ka ho fetisisa (100°F / 38°C): 740 psi Tšebeliso: Mouoane o nang le khatello e mahareng, phepelo ea metsi a indasteri, ts'ebetso ea lik'hemik'hale

Sehlopha sa bo600Khatello e phahameng (ho 100°F / 38°C): 1480 psi Tšebeliso: Liphaephe tsa mouoane, oli le khase tse nang le khatello e phahameng, libaka tsa ho hloekisa

Tekanyo ea khatello ea 900 psi le ho feta(100°F / 38°C): 2200 psi le ho feta. Ditshebediso: Indasteri e kgolo, dipolante tsa motlakase, dipolante tsa lewatle, dipolante tsa matla a nyutlelie.
