Inkqubo ibandakanya i-groove kunye ne-annular lip ebanjwe enye ye-flange kunye neyona ndawo iphakamileyo yokudibanisa nenye i-flange ukwenza umgca wokutywina xa iiflange zihlanganiswa. Umqathango wokuba inkqubo ivuza okanye ayixhomekeke kwimilo kunye nobukhulu bomlomo we-annular kunye nokuguqulwa kwayo ngexesha loqhagamshelwano. Kolu phononongo, iiflange ezininzi ezingenayo i-gasket zilungiswa ngemilinganiselo yomilebe eyahlukeneyo ukuphanda unxibelelwano kunye nemeko yokutywinwa ngovavanyo kunye nohlalutyo lwe-FEM. Uhlalutyo lubonisa ukuba iimeko zingabonakaliswa ngokubhekiselele kuxinzelelo loqhagamshelwano oluphezulu kunye nobukhulu bendawo yeplastiki xa i-flanges ihlanganiswe. Uvavanyo lokuvuza kwe-helium lubonisa ukubai-gasketless flangeinomsebenzi ongcono wokutywina xa kuthelekiswa neegaskets eziqhelekileyo.
