Iyo sisitimu inosanganisira groove uye annular lip iyo inobatwa neimwe yeflange ine iyo yepamusoro nzvimbo yakabatana neimwe flange kuti iite chisimbiso mutsetse kana maflange aungana. Mamiriro ekuti iyo system inodonha kana kuti kwete zvinoenderana nechimiro uye dimension ye annular lip uye deformation yayo panguva yekubata. Muchidzidzo ichi, akati wandei gasketless flanges akagadzirirwa neakasiyana miromo kuti aongorore kusangana uye kuisirwa mamiriro kuburikidza nekuyedza uye FEM ongororo. Ongororo idzi dzinoratidza kuti mamiriro acho anogona kuratidzwa maererano nekunyanya kusangana kushushikana uye saizi yenzvimbo yepurasitiki kana maflange akaunganidzwa. Iyo helium leak yekuongorora inoratidza kuti iyogasketless flangeine kuita kwekuvhara kurinani kana ichienzaniswa neyakajairwa gaskets.
