ʻO ka ʻāʻī kuʻi lima ʻāʻī ʻāʻī a me ka flange lima ʻāʻī ʻelua ʻano ʻano like ʻole o nā flanges, aia kekahi mau ʻokoʻa i ka helehelena a me ka hoʻohana ʻana. ʻO kēia ka mea nui e hoʻokaʻawale ai ma waena o nā flanges welding neck a me nā flanges lima lima.
Keʻano flange:
ʻO ka ʻāʻī kuʻi palahalaha me ka ʻāʻī: ʻO kēia ʻano flange he ʻāʻī kūwaho, i kapa ʻia ʻo ka ʻāʻī a i ʻole ka ʻāʻī o ka ʻāʻī. ʻOi aku ka liʻiliʻi o ke anawaena o ka ʻāʻī ma mua o ke anawaena o waho o ka flange. ʻO ka hele ʻana o ka ʻāʻī e ʻoi aku ka paʻa o ka ʻāʻī wiliwili palahalaha i ka wā e hoʻopili ai i nā paipu.
ʻAʻohe ʻāʻī: ʻAʻohe ʻāʻī o ka ʻāʻī manuahi, a ʻano pālahalaha kona helehelena me ka ʻole o ka ʻāʻī.
Ke kumu:
Necked flat welding flange: hoʻohana pinepine ʻia i nā ʻōnaehana kiʻekiʻe, wela kiʻekiʻe, a me nā ʻōnaehana pipeline me nā koi kiʻekiʻe no ka ikaika pili flange. Ma muli o ka hoʻolālā ʻana o ka ʻāʻī, hiki iā ia ke pale i ke kaomi ʻoi aku ka nui.
Loose flange: Hoʻohana maʻamau no nā noi haʻahaʻa haʻahaʻa a me ka wela maʻamau, maʻalahi kona hoʻolālā a kūpono i kekahi mau manawa me nā koi haʻahaʻa no ka ikaika pili.
Ke ala pili:
ʻO ka flange wili palahalaha me ka ʻāʻī: pili maʻamau i ka pipeline ma ke kuʻi ʻana i ka ʻāʻī o ka flange. ʻO ka welding ka mea e paʻa ai ka pilina a kūpono hoʻi no nā wahi kiʻekiʻe a me ka wela wela.
Loose flange: hiki ke hoʻopili ʻia i ka pipeline ma o nā bolts. He mea maʻalahi ka pilina a kūpono i kekahi mau kūlana haʻahaʻa haʻahaʻa a haʻahaʻa.
Pilikia pili:
ʻO ka flange welding flat me ka ʻāʻī: Ma muli o kona hoʻolālā ʻana, hiki i nā flanges wili palahalaha me ka ʻāʻī ke kū i ke kaomi kiʻekiʻe.
ʻO ka flange wehe: kūpono maʻamau no nā pae kaomi haʻahaʻa.
Ma nā noi kūpono, ʻo ke koho ʻana o ka flange welding neck a i ʻole ka flange lima manuahi e pili ana i nā kūlana hana o ka ʻōnaehana pipeline, ʻoi aku ka nui o ke koi a me nā koi wela. Pono e noʻonoʻo pono ʻia kēia mau mea e hōʻoia i ka hoʻokō ʻana o ke ʻano flange i koho ʻia i nā koi o ka ʻōnaehana.
