ʻO nā flanges nui-diameter kekahi ʻano o nā flanges, i hoʻohana nui ʻia a hoʻolaha ʻia i ka ʻoihana mīkini a ua hoʻokipa maikaʻi ʻia a makemake ʻia e nā mea hoʻohana. Hoʻohana nui ʻia nā flanges nui-diameter, a ua hoʻoholo ʻia ke ʻano o ka hoʻohana e like me nā ʻano like ʻole. Hoʻohana nui ʻia lākou i nā hihia i ʻoi aku ka maʻalahi o nā kūlana waena, e like me ka ea hoʻomaʻemaʻe ʻole i hoʻomaʻemaʻe ʻia a me ka wai kahe haʻahaʻa haʻahaʻa. ʻO kona pōmaikaʻi ʻo ia ke kumukūʻai maʻalahi. Ua kūpono nā flanges i ʻōwili ʻia no nā pilina paipu kila me ke kaomi inoa ʻaʻole ʻoi aku ma mua o 2.5MPa. Hiki ke hana ʻia ka ʻili hoʻopaʻa o ka flange i ʻōwili ʻia i ʻano maʻalahi. ʻO ka nui o ka hoʻohana ʻana i nā flanges i ʻōwili ʻia a me nā ʻano ʻelua ʻelua o nā flanges i ʻōwili ʻia he mea maʻamau hoʻi i ka hoʻohana ʻana.

Hoʻokiʻoki ʻia nā flanges nui-diameter i loko o nā ʻāpana me kahi pā waena a laila ʻōwili ʻia i loko o kahi pōʻai. A laila e hana i nā laina wai, nā puka kī, a me nā mea ʻē aʻe. ʻO ka mea maka he pā waena me ka maikaʻi. Hana ʻia nā flanges nui me ke kila kalapona, ke kila kila, ke kila kila, etc.

Hōʻike nui ʻia nā hiʻohiʻona hana a me ka hoʻohana ʻana i nā flanges nui-diameter i nā wahi i luna. Inā hoʻohana mākou a pau i nā flanges nui-diameter, pono mākou āpau e hoʻomaopopo i kēia mau ʻano i loaʻa iā lākou.

ʻEkolu ʻano o ka flange sealing surfaces nui-diameter: palahalaha sealing surfaces, kūpono no nā manawa me ka haʻahaʻa haʻahaʻa a me nā mea ʻawaʻawa ʻole; concave a convex sealing surfaces, kūpono no nā manawa me ke kaomi kiʻekiʻe iki; ili alelo a me nā ʻauwaha e hoʻopaʻa ʻia ai, kūpono no nā mea pahū, nā mea ʻawaʻawa a me ke kaomi kiʻekiʻe. He aha ke kaʻina hana maikaʻi o nā flanges nui-diameter?

ʻO ke kaʻina hana o nā flanges nui-diameter penei:
ʻO nā flanges nui-diameter i hana ʻia me ka hoʻohana ʻana i nā kaʻina hana like ʻole ko lākou pono a me nā hemahema, akā ʻaʻole kēia ka hihia. No nā flanges nui-diameter i hana ʻia i nā papa waena, ʻo ka mālama ʻana i ke kūlana hui ka mea koʻikoʻi loa. Inā ʻaʻole welded maikaʻi kēia kūlana, hiki mai ka leakage. No nā flanges nui-diameter forged, e loaʻa kahi ʻili o ka flange i hoʻopau ʻia ma hope o ka puka ʻana. Inā paʻi ka puka bolt ma ke kūlana o ka ʻili o ka ʻili, hiki ke kahe wai ke kau ʻia ke kaomi.
