He aha ka flange?

ʻO Flange no ka pōkole, he huaʻōlelo maʻamau wale nō, e pili ana i kahi kino metala like ʻole e wehe ai i kekahi mau puka paʻa, hoʻohana ʻia e hoʻohui i nā mea ʻē aʻe, hoʻohana nui ʻia kēia ʻano mea i nā mīkini, no laila he mea ʻē ke ʻano. ʻoiai ua ʻike ʻia ʻo ia he flange, ua loaʻa kona inoa mai ka ʻōlelo Pelekane.i ka paipu a me ka paipu interconnection o na hapa, i pili i ka hope o ka paipu, i ka flange he aperture, screws e hana i na flanges elua Tightly pili, ma waena o ka flange me ka gasket sila.

 

ʻO ka Flange kahi ʻāpana ʻano diski, ʻo ka mea maʻamau i ka ʻenehana pipeline, hoʻohana ʻia ka flange i ʻelua.

E pili ana i nā ʻano hoʻohui flange, ʻekolu mau ʻāpana:

 

- Pipe flanges

- Puke

- Hoʻohui Bolt

 

I ka hapanui o nā hihia, aia kahi gasket kūikawā a me nā mea bolt i hana ʻia mai ka mea like me ka ʻāpana flange pipe.ʻO nā flanges maʻamau nā flanges stainless steel.ʻO nā flanges, ma ka ʻaoʻao ʻē aʻe, loaʻa i nā ʻano mea like ʻole i mea e hoʻohālikelike ai iā lākou i nā koi o ka pūnaewele.ʻO kekahi o nā mea flange maʻamau he monel, inconel, a me chrome molybdenum, e pili ana i nā koi o ka pūnaewele.ʻO ka koho maikaʻi loa o nā mea pono e hilinaʻi i ke ʻano o ka ʻōnaehana āu e makemake ai e hoʻohana i kahi flange me nā koi kikoʻī.

Ma waho aʻe o ka hoʻolālā hana o kahi flange, ʻo kona nui ka mea nui e hoʻohuli i ka koho flange i ka wā e hoʻolālā ai, mālama a hoʻonui i kahi ʻōnaehana paipu.Akā, pono e noʻonoʻo ʻia ka pili o ka flange me ka paipu a me nā gaskets i hoʻohana ʻia e hōʻoia i ka nui kūpono.Ma waho aʻe o kēia, ʻo kekahi mau manaʻo maʻamau penei:

- ʻO ke anawaena o waho: ʻO ke anawaena o waho ka mamao ma waena o ʻelua ʻaoʻao ʻaoʻao o ka alo flange.

- Mānoanoa: Ana ʻia ka mānoanoa mai waho o ka rim.

- Ke Anawaena Poʻai Bolt: ʻO kēia ka mamao ma waena o nā puka pili pili i ana ʻia mai ke kikowaena a i ke kikowaena.

- Nui Pipe: ʻO ka nui o ka paipu ka nui e like me ka flange.

- Nominal Bore: ʻO ka nominal bore ka nui o ke anawaena o loko o ka mea hoʻohui flange.

Hoʻokaʻawale Flange a me ka pae lawelawe

Hoʻokaʻawale ʻia nā flanges ma muli o ko lākou hiki ke kū i nā ʻano wela a me nā puʻe.Ua koho ʻia e ka hoʻohana ʻana i nā leka a i ʻole nā ​​suffix "#", "lb" a i ʻole "papa".ʻO kēia nā suffix hiki ke hoʻololi a ʻokoʻa hoʻi e ka ʻāina a i ʻole ka mea hoʻolako.ʻO nā papa inoa maʻamau i ʻike ʻia ma lalo nei:

1. Flange palahalaha (FF)

ʻO ka ʻili o ka ʻili palahalaha ma ka mokulele like me ka ʻili o ka pahu bolted.ʻO nā mea kūʻai e hoʻohana ana i nā flanges palahalaha, ʻo ia ka mea i hana ʻia me nā mole e hoʻohālikelike i ka flange a i ʻole ka uhi flange.ʻAʻole pono e kau ʻia nā flanges palahalaha ma nā flanges ʻaoʻao inverted. ASME B31.1 ʻōlelo ʻo ia i ka wā e hui pū ai i nā flanges hao palahalaha i nā flanges kila kalapona, pono e wehe ʻia ka maka i hoʻokiʻekiʻe ʻia ma nā flanges carbon steel a pono e hoʻopaʻa ʻia ke alo piha.ʻO kēia ka mea e pale aku ai i nā liʻiliʻi liʻiliʻi liʻiliʻi o ka hao mai ka pipi ʻana i loko o ka hakahaka i hana ʻia e ka ihu hoʻokiʻekiʻe o ka flange kila kalapona.

Hoʻohana ʻia kēia ʻano maka flange i ka hana ʻana i nā mea hana a me nā kiwi no nā noi āpau kahi i hana ʻia ai ka hao.ʻOi aku ka palupalu o ka hao a hoʻohana mau ʻia no ka haʻahaʻa haʻahaʻa haʻahaʻa.ʻO ka maka palahalaha e hiki ai i nā flanges ʻelua ke hoʻopili piha ma luna o ka ʻili holoʻokoʻa.Loaʻa i nā Flange Flat (FF) kahi ʻili pili e like ke kiʻekiʻe me nā kaula bolt o ka flange.Hoʻohana ʻia nā mea holoi maka holoʻokoʻa ma waena o ʻelua flanges palahalaha a maʻa mau.Wahi a ASME B31.3, ʻaʻole pono e hoʻopili ʻia nā flanges palahalaha me nā flanges kiʻekiʻe ma muli o ka hiki ke hoʻokuʻu ʻia mai ka hui flanged hopena.

2. Hoʻokiʻekiʻe ʻia ka Maka (RF)

ʻO ka flange alo i hoʻokiʻekiʻe ʻia ke ʻano maʻamau i hoʻohana ʻia i nā noi fabricator a ʻike maʻalahi.Kapa ʻia ʻo ia he convex no ka mea aia ka maka o ke kinoea ma luna o ke alo o ke apo bolt.Pono kēlā me kēia ʻano o ke alo i ka hoʻohana ʻana i nā ʻano gaskets, me nā ʻano ʻāpana apo palahalaha a me nā mea hoʻohui metala e like me ke ʻano spiral-wound a me nā ʻano puʻupuʻu pālua.

Hoʻolālā ʻia nā flanges RF e noʻonoʻo hou i ke kaomi ma kahi wahi liʻiliʻi o ka gasket, e hoʻomaikaʻi ai i ka mana kaomi o ka hui.ua wehewehe ʻia nā anawaena a me nā kiʻekiʻe e ka pae kaomi a me ke anawaena ma ASME B16.5.Hōʻike ka pae puʻe Flange i ke kiʻekiʻe o ka maka e hāpai ʻia. Ua manaʻo ʻia nā flanges RF e noʻonoʻo hou i ke kaomi ʻana ma kahi wahi liʻiliʻi o ka gasket, a laila e hoʻonui ai i ka hiki ke hoʻomalu i ke kaomi o ka hui. ASME B16.5.ʻO nā helu flange kaomi.

Ke koi ʻia kahi sila metala ma waena o nā flanges i hoʻopaʻa ʻia (ʻo ia ke kūlana no nā noi kiʻekiʻe a me ka wela wela, ʻo ia hoʻi, ma luna o 700/800 C °), hoʻohana ʻia ka Ring Joint Flange (RTJ).

ʻO ka flange hui apo loaʻa kahi ʻāwī pōʻai e hoʻokomo i ke apo hui pū (oval a i ʻole rectangular).

Ke hoʻopaʻa ʻia nā ʻāpana apo ʻelua a hoʻopaʻa ʻia, hoʻololi ka ikaika o ka bolt i ka gasket i loko o ke awāwa o ka flange, e hana ana i kahi sila metala paʻa loa.I mea e hoʻokō ai i kēia, pono e ʻoi aku ka palupalu o ka mea o ke apo hui pū (ʻoi aku ka ductile) ma mua o ka mea o nā flanges.

Hiki ke hoʻopaʻa ʻia nā flanges RTJ me nā gaskets RTJ o nā ʻano like ʻole (R, RX, BX) a me nā profiles (e laʻa, octagonal/elliptical no ke ʻano R).

ʻO ka gasket RTJ maʻamau ka ʻano R me kahi ʻāpana octagonal, ʻoiai e hōʻoiaʻiʻo ana i kahi sila ikaika loa (ʻo ka ʻāpana oval ke ʻano kahiko).Eia naʻe, ʻae ka hoʻolālā "flat groove" i nā ʻano ʻelua o nā gasket RTJ me kahi ʻāpana octagonal a oval paha.
