1. Mefuta e fapaneng ea weld:
Slip On Flanges: fillet weld e sebelisetsoa ho tjheseletsa pakeng tsa phala ea flange le flange.
Weld Neck Flanges: The seam tjheseletsa pakeng tsa flange le phala ke circumferential weld.
2. Lisebelisoa tse fapaneng:
Slip On Flanges e entsoe ka poleiti e tloaelehileng ea tšepe e nang le botenya bo fihlelang litlhoko.
Weld Neck Flanges hangata e entsoe ka tšepe e entsoeng ka tšepe.
3. Likhatello tse fapaneng tsa lebitso:
Khatello ea lebitso la Slip On Flanges: 0.6 - 4.0MPa
Khatello ea lebitso la Weld Neck Flanges : 1-25MPa
4.Mehaho e fapaneng
Slip On Flanges: e bua ka flange e atolosang liphaephe tsa tšepe, lisebelisoa tsa liphaephe, joalo-joalo ka har'a flange le ho hokahana le lisebelisoa kapa liphaephe ka li-welds tsa fillet.
Weld Neck Flanges: flange e nang le molala le phetoho ea phala, e kopantsoeng le phala ka ho cheselletsa butt.
5.Scope ea kopo:
Slip On Flanges : e sebetsa ho hokahanngoa ha liphaephe tsa tšepe tse nang le khatello ea mabitso e sa feteng 2.5MPa. Sebaka sa tiiso sa flange se ka etsoa ka mefuta e meraro: mofuta o boreleli, mofuta oa concave convex le mofuta oa mortise. Tšebeliso ea flange e boreleli ke eona e kholo ka ho fetisisa E sebelisoa haholo-holo tabeng ea maemo a mahareng a mahareng, joalo ka khatello e tlase e sa hloekisitsoeng moea o hatelitsoeng le metsi a potolohang khatello e tlase.
Weld Neck Flanges : e sebelisetsoa ho cheselletsa butt ea li-flanges le liphaephe. Sebopeho sa eona sea utloahala, matla a eona le ho satalla ha eona li kholo, e khona ho mamella mocheso o phahameng le khatello e phahameng, ho khumama khafetsa le ho fetoha ha mocheso, 'me ho tiisoa ha eona hoa tšepahala. Molala butt welding flange e nang le khatello ea lebitso ea 1.0 ~ 16.0MPa e amohela bokaholimo ba tiiso ea concave convex.
The flat welding flange e ka kopanngoa feela le phala 'me e ke ke ea amahanngoa ka ho toba le phala ea welding ea butt; Li-flange tsa ho tjheseletsa butt ka kakaretso li ka hokahanngoa ka kotloloho ho liphaephe tsohle tsa tjheseletsa tsa butt (ho kenyeletsoa likhau, lithae, liphaephe tse nang le li-diameter tse fapaneng, joalo-joalo), 'me ehlile, liphaephe.
The rigidity ea molala butt tjheseletsa flange e kholo ho feta ea molala bataletseng tjheseletsa flange, 'me butt tjheseletsa matla a phahame ho feta a bataletseng tjheseletsa flange, kahoo ha ho bonolo ho dutla.
Molala o bataletseng oa welding flange le molala butt welding flange o ke ke oa nkeloa sebaka ka thato. Mabapi le tlhahiso, molala o teteaneng oa welding flange (SO flange) o na le warpage e kholo ea ka hare, boima bo fokolang le theko e tlaase. Ho phaella moo, flange ea ho tjheseletsa ha molala e nang le bophara bo boholo ho feta 250 mm (WN ke khutsufatso ea WELDINGCHECK) e hloka ho hlahlojoa, kahoo litšenyehelo li batla li le tlaase.
Ho tjheseletsa sephara ka molala ho sebelisoa haholo lisebelisoa tsa peterole tse tsoang kantle ho naha, tse tšoanang le tsa S0 ea Amerika. Li-flange tse cheselletsang butt li sebelisoa bakeng sa mecha ea litaba e kotsi haholo.
Butt-welding flange e bua ka bophara ba phala le botenya ba lebota la pheletso e kopanyang, e ts'oanang le phala e lokelang ho chesetsoa, joalo ka ha liphaephe tse peli li cheselitsoe.
Flange e bataletseng ea tjheseletsa ke sethala sa concave, lesoba la eona le ka hare le leholo hanyane ho feta bophara ba kantle ba phala, 'me phala e kenngoa ka har'a welding e ka hare.
Ho tjheseletsa ha flat le butt welding ho bolela mekhoa ea ho tjheseletsa ea flange le ho hokela lipeipi. Ha ho tjheseletsa flange e bataletseng, ho hlokahala hore ho be le tjheseletsa e le 'ngoe feela,' me ha ho hlokahale ho kenya phala le khokahanyo ea flange. Ho tjheseletsa le ho kenya tjheseletsa flange ho hloka ho tjhesetswa ka mahlakoreng a mabedi a flange. Ka hona, flange e bataletseng ea tjheseletsa e sebelisoa ka kakaretso bakeng sa khatello e tlase le liphaephe tse mahareng tsa khatello, 'me letlapa la tjheseletsa la butt le sebelisoa bakeng sa khokahano ea phala e mahareng le e phahameng. The butt welding flange ka kakaretso bonyane ke PN2. 5 MPa, sebelisa welding butt ho fokotsa khatello ea maikutlo. Ka kakaretso, butt welding flange e boetse e bitsoa high neck flange le neck flange. Ka hona, litšenyehelo tsa ho kenya, litšenyehelo tsa basebetsi le litšenyehelo tse thusang tsa welding flange li phahame, hobane ho na le ts'ebetso e le 'ngoe feela ea ho cheselletsa flange.
