Flange
- Flanges General
- Flanges amagwiritsidwa ntchito kulumikiza ma valve, mapaipi, mapampu ndi zipangizo zina kuti apange dongosolo la pipework.Nthawi zambiri ma flanges amawotcherera kapena ulusi, ndipo ma flanges awiri amalumikizidwa palimodzi powamanga ndi ma gaskets kuti apereke chisindikizo chomwe chimapereka mwayi wofikira ku mapaipi.Ma Flanges awa amapezeka mumitundu yosiyanasiyana monga slip pa flanges, weld neck flanges, blind flanges, ndi socket weld flanges, etc. Pansipa tafotokozera mitundu yosiyanasiyana ya ma flanges omwe amagwiritsidwa ntchito m'mapaipi amatengera kukula kwake zinthu zina.

Lap Joint Flanges
Mtundu uwu wa flange umakhala ndi nsonga ndi flange. Flange palokha siwowotcherera koma m'malo mwake chimango chimayikidwa / kutsetsereka pamwamba pa flange ndikuwotcherera ku chitoliro.Kukonzekera uku kumathandiza kugwirizanitsa flange muzochitika zomwe kusagwirizana kungakhale vuto.M'mphepete mwa chiwombankhanga, flange palokha sichikhudzana ndi madzi.Mapeto a chishango ndi chidutswa chomwe chimawotchedwa ku chitoliro ndipo chimakhudzana ndi madzimadzi.Mapeto a stub amabwera mumtundu wa A ndipo mtundu wa B. Mapeto amtundu wa A ndiofala kwambiri.Flange yolumikizana ndi lap imangobwera mu nkhope yosalala.Anthu amasokoneza ma flange olowa ndi slip pa flange chifukwa amawoneka ofanana kwambiri, kupatulapo kuti lap joint flange imakhala ndi mbali zozungulira kumbuyo ndi nkhope yosalala.

Socket Weld Flanges
Oyenera kwa ma diameter ang'onoang'ono a chitoliro muzochitika zotsika komanso zotsika kwambiri, ma flanges a socket-weld amakhala ndi kugwirizana komwe mumayika chitoliro mu flange ndiyeno muteteze kugwirizana ndi chowotcherera chimodzi cha multi-pass fillet.Izi zimapangitsa kuti kalembedwe kameneka kakhale kosavuta kuyika kuposa mitundu ina yowotcherera ya flange ndikupewa malire okhudzana ndi ulusi.

Weld Neck Flanges
Welding Neck Flanges ndizosavuta kuzindikira ngati malo otalikirapo, omwe amapita pang'onopang'ono mpaka makulidwe a khoma kuchokera ku chitoliro kapena koyenera.Chipinda chotalikirapo chimakhala ndi chilimbikitso chofunikira kuti chigwiritsidwe ntchito pazinthu zingapo zomwe zimakhudza kuthamanga kwambiri, sub-zero ndi / kapena kutentha kokwera.Kusintha kosalala kuchokera ku makulidwe a flange kupita ku chitoliro kapena makulidwe oyenera a khoma lopangidwa ndi tepi ndikopindulitsa kwambiri, pansi pamikhalidwe yopindika mobwerezabwereza, chifukwa cha kukulitsa kwa mzere kapena mphamvu zina zosinthika. kotero sipadzakhala choletsa kuyenda kwa mankhwala.Izi zimalepheretsa chipwirikiti pa olowa ndi kuchepetsa kukokoloka.Amaperekanso kugawa kwabwino kwambiri kwapakatikati mwa tapered hub. The Weld neck flanges amalumikizidwa ndi matako-kuwotcherera ku mapaipi.Izi zimagwiritsidwa ntchito makamaka pazithandizo zovuta pomwe zolumikizira zonse zowotcherera zimafunikira kuwunika kwa radiographic.Pofotokoza ma flanges awa, makulidwe a kumapeto kwa kuwotcherera kuyeneranso kufotokozedwa limodzi ndi mawonekedwe a flange.

Mitundu ya Flanges
Ulusi wa flange umatchedwanso screwed flange kapena screwed-on flange. sitayilo iyi ili ndi ulusi mkati mwa flange bore womwe umayenderana ndi ulusi wachimuna wofananira pa chitoliro kapena wokwanira.Mtundu uwu wa flange umagwiritsidwa ntchito pomwe kuwotcherera sikoyenera.Flange yopangidwa ndi ulusi imagwiritsidwa ntchito kwambiri pamagetsi otsika komanso mapaipi ang'onoang'ono (mpaka 4 ″ mwadzina).

Slip Pa Flanges
Slip pa Flange Ndi mphete yomwe imayikidwa kumapeto kwa chitoliro, ndi nkhope ya flange yomwe imachokera kumapeto kwa chitoliro ndi mtunda wokwanira kuyika mkanda wowotcherera mkati mwake.Monga momwe dzinalo likusonyezera kuti ma flanges amatsetsereka pa chitoliro ndipo amadziwika kuti Slip On Flanges.Flange yotsetsereka imadziwikanso kuti SO flange.Ndi mtundu wa flange womwe umakhala wokulirapo pang'ono kuposa chitoliro ndipo imatsetsereka pamwamba pa chitoliro, ndi mapangidwe amkati.Popeza gawo lamkati la flange ndi lalikulu pang'ono kuposa mawonekedwe akunja a chitoliro, pamwamba ndi pansi pa flange zitha kulumikizidwa mwachindunji ndi zida kapena chitoliro ndi kuwotcherera kwa SO flange.Amagwiritsidwa ntchito polowetsa chitoliro mu dzenje lamkati la flange.Mapaipi otsekemera amagwiritsidwa ntchito ndi nkhope yokwezeka kapena yosalala.Slip-On Flanges ndi chisankho choyenera pamapulogalamu otsika kwambiri.Slip pa flange imagwiritsidwa ntchito mopitilira muyeso m'mapaipi ambiri amadzimadzi.

Akhungu Flanges
Amagwiritsidwa ntchito pothetsa kapena kudzipatula makina a mapaipi, ma flanges akhungu amakhala ma disks opanda kanthu.Akayika bwino ndikuphatikizidwa ndi ma gaskets olondola, amatha kukwaniritsa chisindikizo chapadera chomwe chimakhala chosavuta kuchotsa pakafunika.
- Kupanga Kulumikizana: Mitundu Yoyang'anizana ndi Flange
- Nkhope ya Flange imapereka njira yolumikizira flange ndi chinthu chosindikizira, nthawi zambiri ndi gasket.Ngakhale pali mitundu yambiri ya nkhope, mitundu yodziwika bwino ya nkhope ya flange ikutsatira;
- Mitundu yoyang'anizana imazindikira ma gaskets onse ofunikira kuti muyike flange ndi mawonekedwe okhudzana ndi chisindikizo chopangidwa.
- Mitundu ya nkhope yodziwika bwino ndi:
- --Nkhope Yathyathyathya (FF):Monga momwe dzinalo likusonyezera, ma flanges a nkhope yosalala amakhala ndi malo ophwanyika, osakanikirana pamodzi ndi nkhope yathunthu yomwe imakhudza mbali zambiri za flange.
- --Nkhope Yokwezeka (RF):Ma flanges awa amakhala ndi gawo laling'ono lokwezeka mozungulira bore ndi mkati mwake mozungulira gasket.
- --Ring Joint Face (RTJ):Amagwiritsidwa ntchito pazovuta kwambiri komanso kutentha kwambiri, mtundu wa nkhope uwu umakhala ndi groove momwe gasket yachitsulo imakhala kuti isunge chisindikizo.
- --Lilime ndi Groove (T&G):Ma flanges awa amakhala ndi grooves yofananira ndi magawo okwera.Izi zimathandizira pakuyika momwe kapangidwe kake kamathandizira ma flanges kuti azitha kudzigwirizanitsa okha komanso kumapereka chosungira chomatira cha gasket.
- --Male & Female (M&F):Mofanana ndi lilime ndi ma groove flanges, ma flangeswa amagwiritsa ntchito mizere yofananira ndi magawo okweza kuti ateteze gasket.Komabe, mosiyana ndi lilime ndi groove flanges, izi zimasunga gasket pa nkhope ya mkazi, kupereka kuyika kolondola komanso kuwonjezereka kwa zinthu zakuthupi.
- Mitundu yambiri ya nkhope imaperekanso imodzi mwazomaliza ziwiri: zopindika kapena zosalala.
- Kusankha pakati pa zosankha ndizofunikira chifukwa zidzatsimikizira gasket yabwino kwa chisindikizo chodalirika.
- Nthawi zambiri, nkhope zosalala zimagwira ntchito bwino ndi ma gaskets achitsulo pomwe nkhope zopindika zimathandizira kupanga zisindikizo zolimba zokhala ndi ma gaskets ofewa.
- Kukwanira Koyenera: Kuyang'ana Pa Flange Dimensions
- Kupatula kapangidwe ka flange, miyeso ya flange ndiyomwe ingakhudze kusankha kwa flange popanga, kukonza, kapena kukonza mapaipi.
- Zolinga zodziwika bwino ndi izi:
- Kukula kwa ma flange kumaphatikizapo zambiri zomwe zatchulidwa, makulidwe a flange, OD, ID, PCD, bolt bolt, kutalika kwa hub, makulidwe a hub, nkhope yosindikiza.Chifukwa chake ndikofunikira kutsimikizira miyeso ya flange musanatsimikizire dongosolo la flange .Malinga ndi kagwiritsidwe ntchito kosiyana ndi muyezo, miyeso ndi yosiyana .Ngati ma flanges adzagwiritsidwa ntchito mu njira yokhazikika ya ASME, ma flange nthawi zambiri amakhala ASME B16.5 kapena B16.47 flanges, osati EN 1092 flanges.
- Chifukwa chake ngati muyitanitsa wopanga flange , muyenera kutchula mulingo wa Flange ndi mulingo wazinthu .
- Ulalo pansipa umapereka miyeso ya flange ya 150 #, 300 # ndi 600 # flanges.
- Pipe Flange Dimension Table
- Flange Classification & Service Ratings
- Chilichonse mwazomwe zili pamwambapa chikhala ndi chikoka pa momwe flange imagwirira ntchito panjira zosiyanasiyana komanso malo.
- Ma Flanges nthawi zambiri amawaika m'magulu malinga ndi luso lawo lotha kupirira kutentha ndi kupanikizika.
- Izi zimasankhidwa pogwiritsa ntchito nambala komanso mawu akuti "#", "lb", kapena "class".Ma suffixes awa amatha kusinthana koma amasiyana malinga ndi dera kapena wogulitsa.
- Magulu odziwika bwino ndi awa:
- -- 150 #
- --300 #
- --600 #
- --900 #
- -- 1500 #
- --2500 #
- Kuthamanga kwenikweni ndi kulekerera kutentha kumasiyana malinga ndi zida zomwe zimagwiritsidwa ntchito, kapangidwe ka flange, ndi kukula kwa flange.Chokhazikika chokha ndichoti nthawi zonse, kupanikizika kumachepa pamene kutentha kumakwera.
