Chiso chakasimudzwa flange(RF) iri nyore kuziva sezvo nzvimbo ye gasket yakamisikidzwa pamusoro peiyo bolting mutsara weflange.
Chiso chakasimudzwaflangeinopindirana neyakasiyana siyana yeflange gaskets, kubva paflat kusvika kune semi-metallic uye esimbi mhando (senge, semuenzaniso, jekete gaskets uye spiral ronda gaskets), ingave mhete kana yakazara kumeso.
Iyo huru chiyero cheyakasimudzwa face flange dhizaini ndeye kutarisisa kudzvanywa kwemaviri mating flanges pane diki nzvimbo uye kuwedzera simba rechisimbiso.
Kureba kwechiso chakasimudzwa kunoenderana neflangepressure rating sekutsanangurwa kwazvinoitwa neASME B16.5 (yekumanikidza makirasi 150 ne300, kureba i1.6 mm kana 1/16 inch, kumakirasi kubva pa400 kusvika 2500, hurefu hwechiso hwakasimudzwa hunosvika 6.4 mm, kana 1/4 inch).
Iyo yakajairika flange kupera kweASME B16.5 RF flanges ndeye 125 kusvika 250 micron Ra (3 kusvika 6 micron Ra).Chiso chakasimudzwa ndechekuti, maererano neASME B16.5, iyo yakasarudzika flange kumeso kupedzisa kune vanogadzira (izvi zvinoreva kuti mutengi anotsanangudza mukurongeka kana imwe flange face ichidikanwa, seyakafuratira kana mhete yekubatanidza).
Yakasimudzwa face flange ndiyo inonyanya tengeswa mhando yeflange, ingangoita petrochemical application.
