Zvinorehwa neKirasi chiyero cheB16 yakatevedzana flange: Chiyero cheKirasi chinodanwa maererano nekushushikana kunobvumidzwa (8750PSI) yeA105, WCB 1.1 zvinhu zveboka pasi pe454 ° C uye kudzvanywa kuyerwa kwakavakirwa pa60.3MP:

• P1=(10S/8750)*Pr≤Pc

P1 - kudzvanywa chiyero cheflange pane inoenderana tembiricha, bar.
S - inobvumirwa kushushikana kukosha kwezvinhu zveflange, MPa.
Pr - flange Kirasi kukosha.

Pc - yakanyanya kudzvanywa rating Bar.

Kune flange yezvinhu 150 # ine inobvumirwa kushushikana kwe100MPa, inowanikwa (10 * 100/8750) * 150 = 17Bar = 1.7MPa.Iyo yakaenzana neinobvumirwa kusagadzikana kwe150 # flange, iyo inobvumirwa kushanda kumanikidza i1.7%.

Maitiro eKusarudza Bolt nzvimbo yeB16 yakatevedzana flange:
Kune flange kana vharafu yekubatanidza muviri:

• AB *7000Psi≥Ag*Pc-> AB *120MPa≥Ag*Pg

Ab - cross sectional area yebhaudhi
Nzvimbo yeAg gasket yekubata kumeso mukati nekunze dhayamita (kusanganisira inotakura nzvimbo mune gasket yemukati dhayamita).
Pc - Kirasi giredhi yeflange
Kutakura simba rebhoti hakuzove kushoma pane fungidziro yekuti kudzvanywa kwemukati kuri mukati mekunze kwedhayamita yegasket sealing surface kana kushushikana kunobvumirwa kwakaenzana ne120MPa.Nekuda kwekubatana kweflange, a193b7 bolt ine simba rekubereka 105ksi (724mpa) inowanzoshandiswa, uye kuchengetedzwa kwekugadzirwa kwebhoti ndeye ns ≥ 6. Nokudaro, nzvimbo yebhoti ye ASME B16.5 flange yakakura kudarika ASME VIII I non. -standard flange.Nekuda kwehuwandu hukuru hwemabhaudhi akawedzera, iyo flange simba kazhinji haina kukodzera kana ikaverengerwa zvinoenderana nefomati.Asi chokwadi, iyo flange yakachengeteka, ndosaka iyo yakatarwa ichiti iyo flange yakasarudzwa zvinoenderana neiyo flange standard yeB16.5 haigone kuverengerwa zvinoenderana neformula.

Zvinorehwa naSch: Sch ipfupiso yehurongwa umpers yehukuru hwepombi.Zvinoreva kuti chiyero chepombi system dhizaini yekumanikidza kune inotenderwa kushushikana pane dhizaini tembiricha inowedzerwa ne100 0 uye kukosha mushure mekutenderera.Semuyenzaniso, kana dhizaini yedhizaini iri 1MPa uye simba rinobvumidzwa repombi riri 100Mpa, pombi ine 1/100 100 0=10 uye> Sch.10 inofanira kushandiswa.Pamapombi akajairwa, kushushikana kunotenderwa kwezvinhu zvakajairika kunosvika 100Mpa, Sch.80 inogona kutakura 8MPa,Sch.160 inogona kutakura 16MPa, zvichingodaro, pane chirevo chakajairika chekusarudza Sch.
