Nā flanges maʻamau ʻoleʻo ia nā mea i hoʻopili ʻia i nā ipu a i ʻole nā ​​paipu ma o ka hoʻoheheʻe ʻana i nā fillet. Hiki i kekahiflange. E nānā i ka flange hoʻohuia i ʻole looper flange e like me ka pono o ke apo flange a me ka ʻāpana pololei.FlangeʻElua ʻano o ke apo: ʻāʻī a me ka ʻāʻī ʻole. Hoʻohālikelike ʻia me kaʻāʻī ʻāʻī, flange maʻamau ʻoleHe maʻalahi ka hana a mālama i nā mea, akā ʻaʻole maikaʻi kona paʻa a me ka hoʻopaʻa ʻana e like me ka flange o ka ʻāʻī.Nā flanges maʻamau ʻolehoʻohana nui ʻia no ka hoʻopili ʻana i nā moku me ka haʻahaʻa haʻahaʻa a me nā pipeline.
Flange maʻamau ʻoleHe kūpono ia no ka haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa, puʻuwai fluctuation, vibration a me ka hopena ʻaʻole koʻikoʻi ka ʻōnaehana pipeline.Nā flanges maʻamau ʻolehoʻohana nui ʻia no ka mea ʻoi aku ka maʻalahi o ka hoʻohālikelike ʻana i ka wā wili a me ka hui ʻana a ʻoi aku ka maʻalahi.

Nā flanges maʻamau ʻolenā apo i hana ʻia i nā mea hiki ke hana i ka deformation plastic a loaʻa kekahi ikaika. Hoʻokiʻoki ʻia ka hapa nui o nā gaskets mai nā ʻāpana non-metallic a i hana ʻia ma ke ʻano like ʻole e kahi hale hana ʻoihana. ʻO ka papa asbestos papa, ka papa asbestos, ka papa polyethylene a pēlā aku. ʻO ia hoʻi kahi pahu hoʻopihapiha metala i hana ʻia me ka asbestos a me nā mea metala ʻole ʻē aʻe i wahī ʻia e kahi pā metala lahilahi (pepa hao, ke kila kila); Hana ʻia kekahi ʻano gasket me ka lipine kila lahilahi a me ka lipine asbestos i ʻoki pū ʻia. He kūpono ka pahu pahu maʻamau no ka manawa o ka mahana ma lalo o 120 ℃; He kūpono ka pahu pahu Rubber no ka mahana wela ma lalo o 450 ℃, ka mahana o ka aila ma lalo o 350 ℃, nā manawa haʻahaʻa haʻahaʻa. Ma ka hihia o 5MPa ma lalo nei, hoʻohana pinepine ʻia ka pā asbestos kūpaʻa i ka wai no ka mea corrosion.
I loko o nā lako paʻi kiʻekiʻe a me nā paipu, hoʻohana ʻia nā ʻāpana metala o nā lens-type a i ʻole nā ​​​​ʻano ʻē aʻe i hana ʻia me ke keleawe, aluminika, 10 kila a me ke kila kila. ʻAʻole maʻamau flange gasket a me ka sila ʻana i ka laula hoʻopili maka he haiki loa (line contact), sila maka a me ka gasket kaʻina hoʻopau pae kiʻekiʻe.
Kahi mea hou aʻe,nā lepa maʻamauhiki ke pale aku i ka ili a me ka pohā. ʻO ka mea maʻamau, e hoʻopili ʻia ka ʻili flange ʻaʻole maʻamau (zinc melemele, zinc keʻokeʻo, a me nā mea ʻē aʻe), a i uhi ʻia me ka ʻaila anti-rust, spray anti-rust paint.
