Butt-welding flange ke e 'ngoe ea li-flanges, e bolelang flange e nang le molala le phetoho ea phala e chitja' me e hokahane le phala ka ho tjheseletsa butt.Hobane bolelele ba molala bo ka aroloa kamolala butt welding flangelemolala o bataletseng welding flange.
Butt-welding flanges e sebelisoa haholo hobane ha ho bonolo ho holofala, e tiisitsoe hantle, e sebelisoa haholo, e na le litlhoko tse tsamaellanang tsa ho tiea le elasticity le phetoho e utloahalang ea ho cheselletsa butt thinning.
Ka nts'etsopele ea kaho ea liphaephe tsa libaka tse telele, flange e entsoeng ka butt-welded e fetohile karolo ea bohlokoa ea teko ea khatello ea lipeipi.Pele le ka mor'a tlhahlobo ea khatello, karolo e 'ngoe le e' ngoe ea liphaephe e hloka ho fieloa ka bolo, ka makhetlo a 4-5.Haholo-holo ka mor'a teko ea khatello, ho thata ho hloekisa metsi ka pipeline, 'me linako tsa ho hloekisa li tla eketseha.
Flat welding flange ke mofuta o mong oaflange.E sebelisoa haholo le ho khothaletsoa indastering ea mechini, 'me e amohetse thoriso le mohau ho tsoa ho basebelisi ba bangata.
Tikoloho e ka sehloohong ea ts'ebeliso ea flange e bataletseng ea welding e loketse, mme boleng bo ikhethileng ba ts'ebeliso le ts'ebetso ea flange e bataletseng ea welding e hloka ho khethoa ho latela maemo a itseng.Ho hlahisa flange ho bonolo ebile ho theko e tlase, empa mosebetsi oa tjheseletsa o moholo, tšebeliso ea li-electrode e kholo, 'me e ke ke ea mamella mocheso o phahameng, khatello e phahameng, ho khumama khafetsa le ho feto-fetoha ha mocheso.Ka kakaretso e sebelisoa bakeng sa liphaephe tse nang le PN ≤ 2.5MPa, mocheso o tloaelehileng, le mocheso oa ho sebetsa t ≤ 0 ℃.
E 'ngoe ke ho cheselletsa weld ea kantle pakeng tsa flange le phala, hape le ho cheselletsa phala e kentsoeng ka har'a flange.Pipe le sefahleho sa flange li tla ts'oaroa ho latela litlhoko tsa kopano ea setšoantšo.Hlokomela hore sefahleho sa flange se ke ke sa senyeha nakong ea welding, ho seng joalo ho tiisa ha ho molemo.Mokhoa oa ho tjheseletsa ke ho tjheseletsa arc ka letsoho, mme ho tjheseletsa ho hlokehang ka mokgwa wa welding ho ka sebediswa.
Molemo
The butt-welding flange e na le sebopeho se utloahalang, matla a phahameng le ho tiea, e khona ho mamella mocheso o phahameng le khatello e phahameng, ho khumama khafetsa le ho feto-fetoha ha mocheso, ts'ebetso e ntle ea ho tiisa, 'me ha ho bonolo ho e senya.E sebetsa haholo ho liphaephe tse nang le khatello e kholo kapa ho fetoha ha mocheso kapa mocheso o phahameng, khatello e phahameng le liphaephe tse tlaase tsa mocheso.Malapeng, bophara ba phala bo nyane, 'me ke khatello e tlase,' me khokahano ea butt welding flange ha e bonahale.Ka kamoreng ea boiler kapa setšeng sa tlhahiso, ho na le liphaephe le lisebelisoa tse hokahaneng ka li-flange tsa butt welding hohle.
Mokhoa oa ho sebetsa oa butt welding flange ke ofe?
1. Ho etsa sekheo se sekoahelo se sekoere billet, ebe ho bata ho kobeha karolong ea arc, ho kenngoa ka mor'a phekolo ea mocheso, ebe o kopanya ka har'a selikalikoe holim'a lathe e otlolohileng ho sebetsa ho sebopeho le boholo bo hlophisitsoeng;
2. Mohato oa pele ke ho tsamaisa ho ea setšeng sa kaho, ebe o kopanya le ho tjheseletsa likarolo tse 'maloa tsa arc ka li-flange tse feletseng tsa li-welding;
3. Li-flange tsa li-butt-welding li na le litekanyetso tse fapaneng tsa tlhahiso ea tlhahiso le tlhahiso, 'me li ka hlahisoa le ho sebelisoa ho ea ka litekanyetso tse lumellanang, e le ho hlokomela boleng ba tšebeliso le mosebetsi oa li-flange tse bōpehileng ka mokhoa o khethehileng.
