He aha nā pōmaikaʻi o ka hoʻohana ʻana i nā flanges nui?
ʻO ka flange nui i ke kaʻina hana e loaʻa nā waiwai like ʻole o ka hoʻohana ʻana, a hana i nā ʻano hana like ʻole a me nā hoʻohana. flange nui ʻokoʻa nā mea like ʻole, ka hana ʻana, a me ka ʻenehana hana ʻana. No laila, i ka hoʻohana ʻana i ka hana ʻana i nā flanges nui e nānā pono i ke ʻano, e hoʻohana ʻia e like me kekahi mau kaʻina hana a me nā ʻano.
Ordinary integral nui flanges i palahalaha welded nui flanges a me butt-welded flanges nui, palahalaha welded nui flanges me ka ilihune rigidity, pili i ke kaomi p ≤ 4MPa manawa, butt-welded flanges nui, i kapa 'ia he kiʻekiʻe-ā'ī nui flanges me kiʻekiʻe rigidity, pili i ke kiʻekiʻe kiʻekiʻe a me ke kiʻekiʻe o ka wela, aia ʻekolu mau ʻano o ka sealing surfaces no nā flanges nui: nā mea hoʻopaʻa paʻa paʻa, kūpono no nā manawa haʻahaʻa a me nā manawa. ʻO ka ʻili hoʻopaʻa convex, kūpono no nā manawa ʻoi aku ka kiʻekiʻe o ke kaomi, ka ʻōlelo a me ka ili hoʻopaʻa ʻana, kūpono no ka flammable, pahū, mea ʻawaʻawa a me nā manawa kiʻekiʻe, ʻokoʻa. ka hana ʻana o nā ʻāpana flange nui, ma nā kahua like ʻole, loaʻa ka hana huahana maikaʻi, i nā manawa like ʻole a ʻokoʻa ka hopena o ka lewa.
ʻO kahi gasket flange nui kahi ʻano apo e hiki ai ke hana i ka deformation plastic a loaʻa kekahi ikaika, ʻo ka hapa nui o nā gaskets he ʻoki ʻoki ʻole a i hana ʻia e nā hale hana kūikawā e nā ana i kuhikuhi ʻia. Loaʻa nā mea hana i nā ʻāpana asbestos, nā pepa asbestos, nā ʻāpana polyethylene, a me nā mea ʻē aʻe. i hanaʻia i nāʻehaʻeha, no nā mea hana kiʻekiʻe a me nā paipu i loko o ka flange nui, ka hoʻohanaʻana i nā lens-type a iʻole nāʻano'ē aʻe o nā'āpana metala i hanaʻia me ke keleawe, aluminika, No. ili liʻiliʻi flange sealing nui He haiki loa ka laula hoʻopili (ka laina laina), a ua hana ʻia ka ʻili o ka sila a me ka gasket me kahi kiʻekiʻe o ka pau.
Hoʻohana nui ʻia kona pili no ka hoʻopili ʻana i nā paipu hao hao, nā paipu kaula hao, nā paipu metala non-ferrous, nā kīwī flange nui, a me nā mea ʻē aʻe. nā lehelehe nui,ʻO nā hiʻohiʻona nui o ka pilina flange nui e maʻalahi e wehe, ikaika kiʻekiʻe, a me ka hana sila maikaʻi. I ka hoʻokomo ʻana i nā flanges nui, pono e mālama like ʻia nā flanges nui ʻelua, ʻaʻole pono e ʻoki ʻia a hoʻomaʻemaʻe ʻia ka ʻili o ka sila, a e koho ʻia ka gasket i hoʻohana ʻia no nā flanges nui e like me nā lula hoʻolālā.
He pilina koʻikoʻi ia i ka hana ʻana o ka pipeline, Ua māhele ʻia lākou i ka pili pili (threaded pili) nui flanges a welded nui flanges, aia nā haʻahaʻa haʻahaʻa liʻiliʻi liʻiliʻi threaded pili nui flanges, kiʻekiʻe-puʻe, haʻahaʻa-puʻe, nui- hoʻohana ʻia ke anawaena e wili i nā ʻāpana nui. ʻO ka mānoanoa o nā flanges nui me nā kaomi ʻokoʻa a ʻokoʻa nā anawaena a me nā helu o nā kī hoʻohui. E like me ka like ole puʻe pae, nui flange gaskets ua hana 'ia me ka like 'ole, mai ka haʻahaʻa-press asbestos gaskets, a me kiʻekiʻe-press asbestos gaskets i metala gaskets.
