CHIYAMBI CHA FLANGE

Mafotokozedwe Akuthupi
Choyamba, flange iyenera kugwirizana ndi chitoliro kapena zida zomwe idapangidwira. Mafotokozedwe enieni a flange za chitoliro ndi monga kukula ndi mawonekedwe a kapangidwe.

Miyeso ya Flange
Miyeso yeniyeni iyenera kufotokozedwa kuti kukula kwa ma flanges kukhale kolondola.

Dayamita yakunja (OD) ndi mtunda pakati pa m'mphepete ziwiri zotsutsana za nkhope ya flange.
Kukhuthala kumatanthauza makulidwe a mkombero wakunja womangirira, ndipo sikuphatikizapo gawo la flange lomwe limagwirira chitoliro.
Chidutswa cha bwalo la bolt ndi kutalika kuyambira pakati pa dzenje la bolt mpaka pakati pa dzenje lotsutsana nalo.
Kukula kwa chitoliro ndi kukula kwa chitoliro chofanana ndi chitoliro cha chitoliro, chomwe nthawi zambiri chimapangidwa motsatira miyezo yovomerezeka. Nthawi zambiri chimayikidwa ndi manambala awiri osafanana, kukula kwa chitoliro chodziwika bwino (NPS) ndi ndandanda (SCH).
Kukula kwa chitoliro chodziwika bwino ndi m'mimba mwake wa cholumikizira cha flange. Mukamapanga ndikuyitanitsa mtundu uliwonse wa cholumikizira cha chitoliro, ndikofunikira kufananiza kukula kwa chitolirocho ndi kukula kwa chitoliro cholumikizira.
Nkhope za Flange
Nkhope za Flange zitha kupangidwa motsatira zofunikira zambiri pakupanga mawonekedwe. Zitsanzo zina ndi izi:

Lathyathyathya
Nkhope yokwezedwa (RF)
Cholumikizira cha mtundu wa mphete (RTJ)
Mzere wa O-ring
Mitundu ya Ma Flange a Mapaipi
Ma flange a mapaipi amatha kugawidwa m'mitundu isanu ndi itatu kutengera kapangidwe kake. Mitundu iyi ndi ya blind, lap joint, orifice, reducing, slip-on, socket-weld, threaded, ndi weld neck.

Ma flange a Blind ndi mbale zozungulira zopanda chogwirira chapakati chomwe chimagwiritsidwa ntchito kutseka malekezero a mapaipi, ma valve, kapena zida. Zimathandiza kuti mzerewo ufike mosavuta ukatsekedwa. Zingagwiritsidwenso ntchito poyesa kuthamanga kwa madzi. Ma flange a Blind amapangidwa kuti agwirizane ndi mapaipi wamba amitundu yonse pamlingo wapamwamba kuposa mitundu ina ya flange.

Ma flange a lap joint amagwiritsidwa ntchito pa mapaipi okhala ndi chitoliro cholumikizidwa kapena ndi malekezero a lap joint stub. Amatha kuzungulira chitoliro kuti alole kuti mabowo a bolt agwirizane mosavuta ngakhale atangomaliza kuluka. Chifukwa cha ubwino uwu, ma flange a lap joint amagwiritsidwa ntchito m'makina omwe amafuna kuchotsedwa kwa ma flange ndi chitoliro nthawi zambiri. Amafanana ndi ma flange otsetsereka, koma ali ndi radius yokhotakhota pa bore ndi nkhope kuti agwirizane ndi malekezero a lap joint stub. Kuthamanga kwa ma flange a lap joint ndi kochepa, koma ndi okwera kuposa ma flange otsetsereka.

Ma flange otsetsereka amapangidwa kuti azitha kutsetsereka kumapeto kwa mapaipi kenako n’kulumikizidwa pamalo pake. Amapereka kuyika kosavuta komanso kotsika mtengo ndipo ndi abwino kwambiri pogwiritsira ntchito mphamvu zochepa.

Ma flange a socket weld ndi abwino kwambiri pa mapaipi ang'onoang'ono komanso amphamvu kwambiri. Kupanga kwawo kuli kofanana ndi kwa ma flange otsetsereka, koma kapangidwe ka mkati mwa thumba kamalola kuti bore ikhale yosalala komanso madzi aziyenda bwino. Ma flange awa akatsetsereka mkati, amakhala ndi mphamvu yotopa ndi 50% kuposa ma flange otsetsereka awiri.

Ma flange opangidwa ndi ulusi ndi mitundu yapadera ya flange ya mapaipi yomwe imatha kulumikizidwa ku chitoliro popanda kuwotcherera. Amapangidwa ndi ulusi mu bore kuti agwirizane ndi ulusi wakunja pa chitoliro ndipo amachepetsedwa kuti apange chisindikizo pakati pa flange ndi chitoliro. Ma weld opangidwa ndi ulusi angagwiritsidwenso ntchito limodzi ndi maulumikizidwe opangidwa ndi ulusi kuti awonjezere mphamvu ndi kutseka. Amagwiritsidwa ntchito bwino pamapaipi ang'onoang'ono komanso kupsinjika kochepa, ndipo ayenera kupewedwa pogwiritsidwa ntchito ndi katundu waukulu komanso mphamvu zambiri.

Ma flange a khosi loswedwa ali ndi hub yayitali yocheperako ndipo amagwiritsidwa ntchito pogwiritsira ntchito mphamvu yamagetsi. Hub yocheperako imasamutsa kupsinjika kuchokera ku flange kupita ku chitolirocho ndipo imapereka mphamvu yolimba yomwe imalimbana ndi mbale.
