FLANGE SEBAKA

Litlhaloso tsa 'Mele
Pele ho tsohle, flange e tlameha ho lekana phala kapa thepa eo e etselitsoeng eona. Litlhaloso tsa 'mele bakeng sa li-flange tsa liphaephe li kenyelletsa litekanyo le libopeho tsa moralo.

Litekanyo tsa Flange
Litekanyo tsa 'mele li lokela ho hlalosoa e le hore boholo ba li-flanges bo nepahale.

Ka ntle ho bophara (OD) ke sebaka se pakeng tsa mahlakore a mabeli a hanyetsanang a sefahleho sa flange.
Botenya bo bolela botenya ba moqomo o ka ntle o hokelang, 'me ha bo kenyelle karolo ea flange e tšoereng phala.
Bolt selikalikoe bophara ke bolelele ho tloha bohareng ba lesoba la bolt ho ea bohareng ba lesoba le hanyetsanang.
Boholo ba liphaephe ke boholo bo tsamaisanang ba phaephe, hangata bo etsoa ho latela maemo a amohelehang. Hangata e hlalosoa ke linomoro tse peli tse se nang lehlakore, boholo ba pipe ea lebitso (NPS) le kemiso (SCH).
Ka lebitso bore boholo ke bophara bo ka hare ba sehokelo sa flange. Ha ho etsoa le ho laela mofuta ofe kapa ofe oa sehokelo sa phala, ke habohlokoa ho bapisa boholo ba sekhechana le boholo ba phala ea ho kopanya.
Lifahleho tsa Flange
Lifahleho tsa Flange li ka etsoa ho latela palo e kholo ea libopeho tse ikhethileng tse ipapisitseng le litlhoko tsa moralo. Mehlala e meng e kenyelletsa:

Sefahleho se phahamisitsoeng (RF)
Mofuta oa lesale (RTJ)
O-ring groove
Mefuta ea Pipe Flanges
Li-pipe flanges li ka aroloa ka mefuta e robeli ho latela moralo. Mefuta ena ke blind, lap joint, orifice, reduction, slip-on, socket-weld, threaded, le weld neck.

Li-blind flanges ke lipoleiti tse chitja tse se nang setsi sa bohareng se sebelisetsoang ho koala liphaephe, li-valve kapa lisebelisoa. Li thusa ho lumella ho fihlella habonolo mohala ha o se o tiisitsoe. Li ka boela tsa sebelisoa bakeng sa tlhahlobo ea khatello ea phallo. Li-flange tse foufetseng li entsoe ho lumellana le liphaephe tse tloaelehileng ka boholo bohle ka litekanyetso tse phahameng tsa khatello ho feta mefuta e meng ea flange.

Li-flanges tse kopantsoeng li sebelisoa liphaepheng tse kentsoeng liphaephe tse kenngoeng kapa tse nang le mapheo a liropeng. Li ka potoloha phala ho lumella ho lokisoa ha bonolo le ho kopanya masoba a bolt esita le ka mor'a hore li-welds li phethoe. Ka lebaka la molemo ona, li-flange tse kopantsoeng tsa lap li sebelisoa lits'ebetsong tse hlokang ho qhaqhoa khafetsa ha li-flange le phala. Li tšoana le li-slip-on flanges, empa li na le radius e kobehileng ho bore le sefahlehong ho amohela pheletsong ea lenonyeletso la lirope. Likhatello tsa khatello ea li-lap joint flanges li tlase, empa li phahame ho feta li-slip-on flanges.

Li-slip-on flanges li etselitsoe hore li thelle qetellong ea liphaephe ebe li chesetsoa sebakeng sa tsona. Li fana ka lisebelisoa tse bonolo le tse theko e tlaase 'me li loketse bakeng sa lisebelisoa tse tlaase tsa khatello.

Li-socket weld flanges li loketse liphaephe tsa boholo bo bonyenyane, tse nang le khatello e phahameng. Boqapi ba bona bo tšoana le ba li-slip-on flanges, empa moralo o ka hare oa pokotho o lumella hore ho be le boreleli le phallo e ntle ea mokelikeli. Ha li tjheselitsoe ka hare, li-flange tsena li boetse li na le matla a mokhathala a 50% ho feta li-flange tse peli tse cheselitsoeng.

Li-flanges tse nang le likhoele ke mefuta e khethehileng ea liphaephe tse ka kopanngoang le phala ntle le welding. Li khoele ka har'a bore ho bapisa khoele e kantle holim'a phaephe 'me li teiloe ho etsa tiiso pakeng tsa flange le phala. Li-welds tsa tiiso le tsona li ka sebelisoa hammoho le likhokahano tse kentsoeng bakeng sa ho tiisa le ho tiisa. Li sebelisoa ka ho fetisisa bakeng sa liphaephe tse nyenyane le likhatello tse tlaase, 'me li lokela ho qojoa lits'ebetsong tse nang le meroalo e meholo le li-torque tse phahameng.

Li-welding neck flanges li na le sebaka se selelele sa tapered 'me se sebelisetsoa ho sebelisa khatello e phahameng. The tapered hub fetisa khatello ea kelello ho tloha flange ho phala ka boeona 'me e fana ka matlafatso a matla a hanyetsanang le lijana.
