Isistimu ihlanganisa i-groove kanye nodebe oluhlala njalo olubanjwe enye ye-flange enephuzu layo eliphakeme kakhulu lixhumene nelinye i-flange ukuze kwakheke umugqa wokuvala lapho ama-flange ehlanganiswa. Isimo sokuthi isistimu iyavuza noma cha incike ekumeni kanye nobukhulu bodebe lwe-annular kanye nokuguqulwa kwayo ngesikhathi sokuxhumana. Kulolu cwaningo, ama-flange amaningana angenayo i-gasketless alungiswa anezilinganiso ezihlukene zezindebe ukuze kuphenywe ukuthintwa kanye nesimo sokuvala ngokuhlolwa nokuhlaziya kwe-FEM. Ukuhlaziya kubonisa ukuthi izimo zingavezwa ngokuhambisana nokucindezeleka okukhulu kokuxhumana kanye nobukhulu bendawo yepulasitiki lapho ama-flange ehlanganiswa. Ukuhlolwa kokuvuza kwe-helium kuveza ukuthii-gasketless flangeinokusebenza okungcono kokuvala uma kuqhathaniswa nama-gaskets avamile.
