Ho fihlela litlhoko tse phahameng tsa bareki bakeng sa khatello ea metsi le khatello ea moea moralong oaflange motlakase o futhumatsang li-tubes,Ntlafatso e felletseng ea hlokahala ho tsoa litekanyong tse fapaneng joalo ka khetho ea thepa, moralo oa sebopeho, ts'ebetso ea tlhahiso, le netefatso ea ts'ebetso. Morero o ikhethileng ke o latelang:
1,Khetho ea thepa: Ntlafatsa matla a hatellang le motheo oa ho tiisa
1. Khetho ea lisebelisoa tse kholo tsa pipe
Matla a phahameng le lisebelisoa tse thibelang ho bola li khethoa bakeng sa maemo a sebetsang a khatello e phahameng (khatello ea metsi≥10MPa kapa khatello ea moea≥6MPa), joalo ka:
316L ea tšepe e sa hloekang (e hanana le mecha ea litaba e senyang ka kakaretso, matla a hatellang≥520MPa);
Incoloy 800 (e hanyetsanang le mocheso o phahameng, khatello e phahameng le oxidation, e loketseng tikoloho ea mocheso o phahameng oa mocheso, matla a tlhahiso.≥240MPa);

Botenya ba lerako la phala bo baloa ho ea ka litekanyetso tsa GB/T 151 Heat Exchanger kapa ASME BPVC VIII-1, ho netefatsa hore moeli oa lebota la botenya≥20% (joalo ka ho bala botenya ba lebota + 0.5mm ntlha ea polokeho ha khatello ea ho sebetsa e le 15MPa).
2. Flange le tiiso e nyalanang
Mofuta oa Flange: Maemong a khatello e phahameng, ho sebelisoa li-flange tsa neck welding (WNRF) kapa integral flanges (IF), 'me sebaka sa ho tiisa se khethoa e le mortise le tenon (TG) kapa ring joint (RJ) ho fokotsa kotsi ea ho koala ho tsoa holim'a metsi.
Ho tiisa gasket: Khetha gasket e phuthetsoeng ka tšepe (e nang le mehele ea ka hare le ea ka ntle) (ho hanyetsa khatello≤25MPa) kapa octagonal metal ring gasket (khatello e phahameng le mocheso o phahameng, ho hanyetsa khatello≥40MPa) ho latela litšobotsi tsa seaplane. Thepa ea gasket e lumellana le thepa ea phala (e kang 316L gasket e nang le 316L flange).
2,Moralo oa Sebopeho: Ho Matlafatsa Khatello le ho Tšepahala
1. Ho ntlafatsa sebopeho sa mechine
Moralo oa ho kobeha: Qoba ho kobeha lehlakoreng le letona 'me u sebelise radius e kholo ea curvature (R≥3D, D ke bophara ba phala) ho fokotsa khatello ea maikutlo; Ha ho etsoa liphaephe tse ngata, li aroloa ka mokhoa o ts'oanang ho leka-lekanya matla a radial.
Sebopeho se matlafatsang: Eketsa mehele ea tšehetso (spacing≤1.5m) kapa lithupa tse hahelletsoeng ka hare ho sebaka se otlolohileng se seleleletube e futhumatsang ho thibela deformation ea 'mele oa tube tlas'a khatello e phahameng; Karolo ea khokahanyo pakeng tsa flange le 'mele oa liphaephe e nka sebaka sa phetoho se teteaneng (gradient groove welding) ho matlafatsa khanyetso ea ho taboha ea seam ea weld.
2. Ho tiisa le ho hokahanya moralo
Ts'ebetso ea welding: 'Mele oa liphaephe le flange li kene ka ho feletseng ka li-welded (tse kang TIG welding + filler terata), le tlhahlobo ea X-ray ea 100% (RT) kapa tlhahlobo ea ho kenella (PT) e etsoa ka mor'a ho cheselletsa ho etsa bonnete ba hore seam weld ha se na pores le mapetsong;
Thuso ea ho atolosa: Thepa ea phapanyetsano ea mocheso e hokahane le poleiti ea tube e sebelisa mekhoa e 'meli ea ho atolosa hydraulic le ho tiisa welding. Khatello ea ho atolosa ke≥habeli khatello ea ho sebetsa ho thibela ho lutla ha mahareng ho tsoa mekoting ea li-tube plate.
3,Mokhoa oa tlhahiso: taolo e tiileng ea mefokolo le botsitso
1. Taolo ea ho nepahala ha mochini
Ho seha liphaephe ho amohela ho itšeha ka laser / CNC, ka sefahleho sa sefahleho sa perpendicularity≤0.1mm; flange ho tiisa bokahodimo≤Ra1.6μ m, bolt lesoba junifomo kabo phoso≤0.5mm, ho netefatsa matla a tšoanang nakong ea ho kenya.
Ho tlatsa phofo ea Magnesium oxide: ho sebelisa theknoloji ea compaction ea vibration, ho tlatsa letsoalo≥2.2g/cm³, ho qoba ho chesa ho feteletseng kapa ho hloleha ha insulation ho bakoang ke likarolo tse se nang letho (insulation resistance≥100MΩ/500V).
2. Teko ea khatello ea maikutlo le ho netefatsa
Teko ea pele ho feme:
Teko ea Hydrostatic: Khatello ea teko ke makhetlo a 1.5 khatello ea ho sebetsa (e kang 10 MPa khatello ea ho sebetsa le khatello ea teko ea 15 MPa), 'me ha ho na khatello ea khatello ka mor'a ho tšoara metsotso ea 30;
Teko ea khatello (e sebetsang ho mecha ea litaba ea khase): Khatello ea teko ke makhetlo a 1.1 khatello ea ho sebetsa, e kopantsoe le ho lemoha leak ea helium mass spectrometry, ka sekhahla sa ho lutla.≤1 × 10 ⁻⁹mbar· L/s.
Teko e senyang: Sampling e sebelisetsoa tlhahlobo ea khatello ea ho phatloha, 'me khatello ea ho phatloha e tlameha ho ba joalo≥makhetlo a 3 khatello ea ho sebetsa ho netefatsa moeli oa polokeho.
4,Ho ikamahanya le maemo: ho sebetsana ka katleho le maemo a thata a ho sebetsa
1. Matšeliso a katoloso ea mocheso
Ha bolelele batube e futhumatsang is ≥2m kapa phapang ea mocheso ke≥100℃, motsoako oa katoloso ea waveform kapa karolo ea khokahanyo e feto-fetohang e lokela ho kenngoa ho lefella deformation ea mocheso (chelete ea ho atolosaΔ L=α L Δ T, kaeα ke lisebelisoa tsa katoloso ea khokahanyo) 'me u qobe ho hloleha ho koala ha flange ho bakoang ke khatello ea mocheso.
2. Taolo ea mojaro oa sefahleho
Mecha ea litaba ea khatello e phahameng (haholo-holo likhase) e na le maikutlo a ho chesa haholo sebakeng seo 'me e hloka phokotso ea mojaro o ka holim'a metsi (≤8W/cm²). Ka ho eketsa palo kapa bophara batube e futhumatsangs, ho qhalakanya matla a matla, le ho thibela ho phahama kapa ho theoha ha lintho tse bonahalang (joalo ka boima ba bokaholimo≤6W/cm² nakong ea ho futhumatsa mouoane).
3. Moralo oa ho lumellana le mecha ea litaba
Bakeng sa maro a khatello e phahameng a nang le likaroloana/litšila, skrine ea sefe (ka nepo ea≥100 mesh) kapa sekoaelo se tataisang se lokela ho kengoa moo ho kenang teng tube e futhumatsang ho fokotsa khoholeho; Mecha ea litaba e senyang e hloka phekolo e eketsehileng ea ho feta / ho fafatsa (joalo ka polytetrafluoroethylene coating, ho hanyetsa mocheso≤260℃).
5,Moqapi o tloaelehileng le o hlophisitsoeng
Fana ka litlaleho tsa lintho tse bonahalang, mangolo a ts'ebetso ea welding (PQR), le litlaleho tsa liteko tsa khatello ho latela maemo a naha (GB 150 "Lijana tsa Khatello", NB/T 47036 "Electric Heating Elements") kapa litekanyetso tsa machaba (ASME BPVC, PED 2014/68/EU).
Ho fihlela litlhoko tse ikhethang tsa bareki (joalo ka ho futhumatsa ka khatello e phahameng bakeng sa lisebelisoa tsa API 6A le ho futhumatsa metsi a tebileng a leoatle), re sebelisana 'moho le bareki ho etsisa maemo a ts'ebetso (joalo ka tlhahlobo e felletseng ea phepelo ea khatello ea maikutlo le ts'ebetso ea phallo ea CFD) le ho etsa litlhophiso tsa flange (joalo ka li-flange tse khethehileng le lisebelisoa tse hanyetsanang le sebabole).
akaretsa
Ka ts'ebetso e felletseng ea "garantiation ea matla a thepa→moralo oa ho hana boima ba sebopeho→taolo ea ho nepahala ha tlhahiso→tlhahlobo le netefatso e koetsoeng", theflange motlakase o futhumatsang tube e ka finyella ts'ebetso e ka tšeptjoang tlas'a maemo a phahameng a motlakase. Ntho ea mantlha ke ho leka-lekanya matla a ho jara khatello, ts'ebetso ea ho tiisa, le botsitso ba nako e telele, ha ho ntse ho nahanoa ka litšoaneleho tsa sebaka sa moreki (mocheso, corrosiveness, sekhahla sa phallo) bakeng sa moralo o reriloeng, qetellong o fihlela tlhoko ea polokeho ea khatello ea metsi / khatello ea moea.≥Ka makhetlo a 1.5 ho li-parameter tsa moralo.
