SELELEKELA SA FLANGE

Litlhaloso tsa 'Mele
Sa pele le sa bohlokoa, flange e lokela ho lekana le phaephe kapa thepa eo e etselitsoeng eona. Litlhaloso tsa 'mele bakeng sa li-flange tsa phaephe li kenyelletsa litekanyo le libopeho tsa moralo.

Litekanyo tsa Flange
Litekanyo tsa 'mele li lokela ho hlalosoa e le hore ho be le boholo ba li-flange ka nepo.

Bophara ba kantle (OD) ke sebaka se pakeng tsa mathoko a mabeli a fapaneng a sefahleho sa flange.
Botenya bo bolela botenya ba moedi o ka ntle o hokelang, mme ha bo kenyelletse karolo ea flange e tšoereng phaephe.
Bophara ba selikalikoe sa bolt ke bolelele ho tloha bohareng ba lesoba la bolt ho ea bohareng ba lesoba le fapaneng.
Boholo ba phaephe ke boholo ba phaephe bo tsamaellanang le phaephe ya phaephe, ka kakaretso bo etswa ho ya ka maemo a amohetsweng. Hangata bo bolelwa ka dinomoro tse pedi tse sa lekanang, boholo ba phaephe bo tlwaelehileng (NPS) le kemiso (SCH).
Boholo ba mokoti o tloaelehileng ke bophara ba kahare ba sehokelo sa flange. Ha o etsa le ho odara mofuta ofe kapa ofe wa sehokelo sa phaephe, ho bohlokwa ho bapisa boholo ba mokoti wa sengoathoana le boholo ba mokoti wa phaephe e kopanyang.
Lifahleho tsa Flange
Lifahleho tsa Flange li ka etsoa ho latela litlhoko tse ngata tsa moralo tse ipapisitseng le libopeho tse ikhethileng. Mehlala e meng e kenyelletsa:

Sephara
Sefahleho se phahamisitsoeng (RF)
Sehokelo sa mofuta oa lesale (RTJ)
Morokho oa O-ring
Mefuta ea Li-Flanges tsa Pipe
Li-flange tsa liphaephe li ka aroloa ka mefuta e robeli ho latela moralo. Mefuta ena ke blind, lap joint, orifice, reducing, slip-on, socket-weld, threaded, le weld neck.

Li-flange tse foufetseng ke lipoleiti tse chitja tse se nang setsi se sebelisetsoang ho koala lipheletso tsa liphaephe, li-valve, kapa lisebelisoa. Li thusa ho lumella ho fihlella habonolo mohala hang ha o koetsoe. Li ka boela tsa sebelisoa bakeng sa teko ea khatello ea phallo. Li-flange tse foufetseng li etselitsoe ho lekana liphaephe tse tloaelehileng ka boholo bohle ka litekanyetso tse phahameng tsa khatello ho feta mefuta e meng ea li-flange.

Li-flange tsa mahlakore a kopaneng li sebelisoa holim'a liphaephe tse kentsoeng phaephe e kobehileng kapa tse nang le lipheletso tsa stub tsa mahlakore a kopaneng. Li ka potoloha phaephe ho lumella ho lekola habonolo le ho kopanya masoba a liboto esita le ka mor'a hore li-weld li phetheloe. Ka lebaka la molemo ona, li-flange tsa mahlakore a kopaneng li sebelisoa lits'ebetsong tse hlokang ho qhaqhoa khafetsa ha li-flange le phaephe. ​​Li tšoana le li-flange tse thellang, empa li na le radius e kobehileng bore le sefahlehong ho amohela pheletso ea stub ea mahlakore a kopaneng. Litekanyetso tsa khatello bakeng sa li-flange tsa mahlakore a kopaneng li tlase, empa li phahame ho feta tsa li-flange tse thellang.

Li-flange tse thellang li etselitsoe ho thellisa holim'a pheletso ea liphaephe ebe li kopanngoa sebakeng sa tsona. Li fana ka ho kenngoa habonolo le ka theko e tlase 'me li loketse lits'ebetso tse tlase tsa khatello.

Li-flange tsa ho weld tsa sokete li loketse liphaephe tse nyane, tse nang le khatello e phahameng. Tlhahiso ea tsona e tšoana le ea li-flange tsa ho slip-on, empa moralo oa ka hare oa pokotho o lumella mokoti o boreleli le phallo e ntle ea mokelikeli. Ha li slip-on ka hare, li-flange tsena li boetse li na le matla a mokhathala a fetang 50% ho feta li-flange tsa ho slip-on tse slip-on tse slip-on tse slip-on tse slip-on.

Li-flange tse nang le khoele ke mefuta e ikhethang ea flange ea phaephe e ka hokelloang phaepheng ntle le ho tjheseletsa. Li kentsoe khoele ka har'a mokoti ho lumellana le khoele ea kantle phaepheng 'me lia tenyetseha ho etsa tiiso pakeng tsa flange le phaephe. ​​Li-weld tsa seal li ka boela tsa sebelisoa hammoho le likhokahano tse nang le khoele bakeng sa ho matlafatsa le ho tiisa haholoanyane. Li sebelisoa hantle bakeng sa liphaephe tse nyane le khatello e tlase, 'me li lokela ho qojoa lits'ebetsong tse nang le meroalo e meholo le li-torque tse phahameng.

Li-flange tsa molala oa ho tjheseletsa li na le hub e telele e nang le tape 'me li sebelisoa bakeng sa lits'ebetso tsa khatello e phahameng. Hub e nang le tape e fetisetsa khatello ho tloha flange ho ea phaepheng ka boeona 'me e fana ka matla a ho matlafatsa a thibelang ho lahla.
