EN1092-1 Paheʻe ma ka pā Flange Kuʻikuʻi Kuʻikuʻi Pāʻani Flange

Hoʻolauna Huahana

He ʻano flange i hoʻopili ʻia me ka paipu ma ka weld fillet.ʻO ka paheʻe ma luna o ka pāpaʻa he flange kūʻokoʻa.Ke hoʻohālikelike ʻia me ka ʻāʻī kuʻi ʻana o ka ʻāʻī, ʻoi aku ka maʻalahi o ka flange ma luna o ka pā a me ka liʻiliʻi o nā mea, akā ʻaʻole maikaʻi kona paʻa a me ka hoʻopaʻa ʻana.ʻāʻī wiliwili ʻāʻī.Hoʻohana nui ʻia ka slip on plate flange i ka hoʻopili ʻana i nā moku a me nā paipu haʻahaʻa.No ke kumu kuai o kapaheʻe ma luna o ka pā flangeHe nui i ka paipu kaomi, akā ʻilihune kona rigidity, ʻaʻole pono e hoʻohana ʻia i ka pipeline kiʻekiʻe, flammable a explosive pipeline a me ka pipeline kaʻina hana kemika me nā koi kiʻekiʻe.

Hoʻohana pinepine ʻia ma ka ʻāina a me nā ʻāina ʻē aʻe: Nā kūlana o ka Ministry of Chemical Industry: HG/T20592-2009, HG/T20615-2009;Kūlana ʻAmelika: ASME B16.5, ASME B16.47;Nā kūlana aupuni: GB/T9124.1-2019, GB/T9124.2-2019.

Kūlana maʻamau no ka flange paheʻe ma ka pā

ʻO Flange kahi ʻano mea hoʻohui e hiki ke ʻike i ka pilina a me ka hui ʻana o nā pipeline a me nā ʻāpana ma waena o nā mea hana.Hoʻohana nui ʻia ia i ke kinoea, petrochemical, pharmaceutical, metallurgy, pepa, ikehu, condensation, mālama wai a me nā kūlana hana ʻoihana ʻē aʻe.I kēia manawa, ʻo ka flange ʻoki wela ka mea nui loaflange maʻamauʻano ma ka mākeke, a ʻo ia kekahi o nā ʻano kumu nui i hoʻohana ʻia i nā ʻano hana hoʻopili pili

E like me ka laʻana o ka ʻoki ʻana i ka flange ʻokiʻoki ʻoi aku ka hōʻoia ʻana i ka pololei a me ka pāpā ʻana i nā mea hana, ʻo kēia pepa ka mea nui i ka flange i hana ʻia me ka pā kila, hiki ke hoʻokaʻawale ʻia i ʻelua ʻāpana: flat welding flange a me extrusion flange.

Hoʻokumu ʻia ka flange welding flat ma ke kumu o ka ʻoki ʻana a me ka ʻoki ʻana i nā ʻaoʻao, a ua hui pū ʻia nā papa kila ma nā ʻaoʻao e ka welding e hana i kahi hale holoʻokoʻa.

ʻO nā ʻanuʻu nui o ka hana flange welding flat penei:
(1) E koho i ka pā kila kūpono: i ka hoʻololi ʻana i ka nui o ka hoʻomanawanui, e noʻonoʻo pono i ka nui o ka pā kila i koho ʻia
(2) ʻOki a ʻokiʻoki: hoʻohana i ka mīkini ʻoki ʻoki kila a me ka mīkini polishing e ʻoki i ka pā kila no ka hoʻokō ʻana i ka pololei a me nā koi proportionality.
(3) Ke kuʻi ʻana o ka pā kila: e hoʻopaʻa i ka wili arc linear, e hoʻopaʻa i ka ʻaoʻao o ka pā kila me kahi puʻupuʻu liʻiliʻi, a hoʻohui i kahi weld kū i ka weld.
(4) Hui a me ka hoʻoponopono: hoʻokomo a hoʻoponopono i nā ʻāpana like ʻole e hōʻoia i ke kūlike a me ke kuhikuhi o ka nui a me ke kaula.
(5) Nānā: Hoʻohana ʻia nā calipers Vernier e ana i ka mānoanoa flange, ke anawaena o waho a me ka laula weld.Hoʻohana ʻia nā calipers vernier e ana i ka nui o ka flange.
(6) Hoʻopololei: hoʻolalelale i nā hakahaka o ka lihi e hoʻomaikaʻi i ke kiʻi hiʻohiʻona.

ʻO nā lawelawe hoʻoponopono āpau i luna no nā flanges welding flat i hana ʻia i nā papa kila e hana ʻia e like me nā koi o nā kūlana ʻoihana e hōʻoia i kēlā me kēia huahana a me ka paʻi ʻana ma ka pā kila i nā koi ʻenehana.I ka manawa like, e hōʻoia i ka hoʻokō ʻana i nā koi o ka mea palekana, ke ʻano a me ka lōʻihi o ka huahana.
