ʻO nā flanges nā ʻāpana like ʻole i maʻamau i ka ʻenehana pipeline.Hoʻohana ʻia nā flanges i ʻelua a me nā flanges pili i nā kiwi.I ka ʻenehana pipeline, hoʻohana nui ʻia ka flange no ka pilina pipeline.I ka pono e hoʻohui i ka paipu, ʻokoʻa ka hoʻokomo ʻana i kahi flange, hiki ke hoʻohana i ka flange uea haʻahaʻa haʻahaʻa, ʻoi aku ka nui o 4 kg o ka puʻe welded flange.E kau i ka pahu ma waena o nā ʻāpana ʻelua a hoʻopaʻa iā lākou me nā bolts.He ʻokoʻa ka mānoanoa o nā flanges o nā kaomi like ʻole a hoʻohana i nā bolts ʻokoʻa.
ʻO nā paila wai a me nā kiwi, ke hoʻopili ʻia me nā paipu, hana ʻia nā ʻāpana kūloko o kēia mau mea hana i ke ʻano flange kūpono, ʻike ʻia hoʻi ʻo ka pili flange.ʻO nā mea āpau i loko o nā mokulele ʻelua ma ka ʻaoʻao o ka hoʻohana ʻana i ka pili bolt i ka manawa like i pani ʻia i nā ʻāpana pili, i kapa ʻia ʻo "flange", e like me ka hoʻopili ʻana o ka paipu ventilation, hiki ke kapa ʻia kēia ʻano ʻāpana "nā ʻāpana flange class".Akā,ʻo kēia pilina he hapa wale nō ia o nā mea hana, e like me ka hoʻohuiʻana o ka flange a me ka paila wai,ʻaʻole maikaʻi e kapa i ka paila wai "nā'āpana flange".Hiki ke kapa ʻia nā ʻāpana liʻiliʻi, e like me nā valves, "nā ʻāpana flange".
ʻO ke kila flange gasket he ʻano apo i hana ʻia i nā mea hiki ke hana i ka deformation plastic a loaʻa kekahi ikaika.ʻO ka hapa nui o nā gaskets i ʻoki ʻia mai nā papa non-metallic, a i ʻole i hana ʻia e nā ʻoihana ʻoihana e like me ka nui i ʻōlelo ʻia, ʻo ka mea hana he papa asbestos rubber, asbestos board, polyethylene board, etc.;ʻO ka pā metala lahilahi (pepa hao, ke kila kila) asbestos a me nā mea metala ʻole ʻē aʻe i wahī ʻia me ka pahu metala;Aia kekahi puʻupuʻu wili i hana ʻia me ka lipine kila lahilahi me ka lipine asbestos.ʻO ka pahu pahu maʻamau kūpono no ka mahana ma lalo o 120 ℃ mau manawa;ʻO ka pahu asbestos rubber gasket he kūpono ia no ka wela o ka wai ma lalo o 450 ℃, ka mahana o ka aila ma lalo o 350 ℃, ke kaomi ma lalo o 5MPa mau manawa, no ka media corrosive maʻamau, ʻo ka mea maʻamau i hoʻohana ʻia ʻo ka papa asbestos kūpaʻa i ka waikawa.I nā mea hana kiʻekiʻe a me nā pipelines, ka hoʻohana ʻana i ke keleawe, ke alumini, ke kila 10, ke kila kila i hana ʻia i ke ʻano lens a i ʻole nā ʻano ʻē aʻe o nā gasket metala.He haiki loa ka laula pili ma waena o ke kaomi kiʻekiʻe a me ka ili hoʻopaʻa (line contact), a kiʻekiʻe ka pau ʻana o ka hana ma waena o ka ili a me ka gasket.
ʻOkoʻa ka flange puʻupuʻu liʻiliʻi liʻiliʻi, kaomi kiʻekiʻe a me ka haʻahaʻa haʻahaʻa ke anawaena nui, ʻokoʻa ka mānoanoa o ka flange puʻe a me ke anawaena bolt a me ka helu.
