Phaephe ea tšepe e se nang mohele ea motsoako oa A335P92, litlhaloso tse 48.3*7.14 (ke hore, bophara ba kantle ke 48.3mm, botenya ba lebota ke 7.14mm), joalo ka phaephe ea boiler ea khatello e phahameng, tekanyetso ea eona ea ts'ebetso ke ASTM A335M. Se latelang ke tlhahlobo e qaqileng ea phaephe ea tšepe:
I. Kakaretso ea motheo ea Liphaephe tsa Boiler tsa Tšepe
Phaephe ea tšepe e se nang mokelikeli ea motsoako oa A335P92 ke mofuta oa phaephe ea tšepe e se nang mokelikeli ea boleng bo holimo ea mocheso o phahameng le khatello e phahameng ea motsoako, e sebelisoang haholo tikolohong ea mocheso o phahameng le khatello e phahameng joalo ka phaephe e kholo ea mouoane le phaephe ea mouoane e futhumatsoang bocha ea lifeme tsa motlakase tse futhumatsang. Thepa ea eona ke P92, e leng ea tšepe ea United States ea nomoro ea ASTM A335 P92 martensitic e hanelang mocheso.
Ea bobeli, metsoako ea lik'hemik'hale tsa Li-Tubes tsa Boiler tsa Tšepe
Sebopeho sa lik'hemik'hale sa phaephe ea tšepe e se nang seamless ea A335P92 se laoloa hantle, haholo-holo ho kenyeletsoa khabone, manganese, phosphorus, sebabole, silicon, chromium, molybdenum, vanadium, naetrojene, nickel, aluminium, niobium, tungsten le boron le likarolo tse ling. Mefuta e ikhethileng ea litaba ke e latelang:
Khabone (C): 0.07~0.13%
Manganese (Mn): 0.30-0.60%
Fosforase (P): ≤0.020%
Sebabole (S): ≤0.010%
Silicone (Si): ≤0.50%
Chromium (Cr): 8.5~9.50%
Molybdenum (Mo): 0.30~0.60% (empa hoa hlokomeleha hore ha e bapisoa le tšepe ea SA-335P91, tšepe ea SA-335P92 e fokotsa ka nepo litaba tsa karolo ea Mo, 'me e ntlafatsa ts'ebetso ea thepa ka ho eketsa palo e itseng ea W)
Vanadium (V): 0.15~0.25%
Naetrojene (N): 0.03~0.07%
Nikele (Ni): ≤0.40%
Aluminium (Al): ≤0.04%
Niobium (Nb): ≤0.040~0.09%
Tungsten (Bophara): 1.5~2.0%
Boron (B): 0.001~0.006%
Karolo e utloahalang ea likarolo tsena e etsa hore phaephe ea tšepe e se nang moalo ea A335P92 e be le khanyetso e ntle ea mafome a mocheso o phahameng, khanyetso ea oxidation, matla a mocheso o phahameng le litšobotsi tsa ho kheloha.
3. Thepa ea mechini ea li-Tube tsa Boiler tsa Tšepe
Phaephe ea tšepe e se nang sekoli ea motsoako oa A335P92 e na le thepa e ntle ea mechini, e bontšitsoeng ka tsela e latelang:
Matla a ho thapolla: ≥620MPa
Matla a tlhahiso: ≥440MP
Matlotlo ana a mechini a netefatsa polokeho le botshepehi ba dipeipi tsa tshepe maemong a mocheso o phahameng le kgatello e phahameng.
4. Tšimo ea ts'ebeliso ea Li-Tubes tsa Boiler tsa Tšepe
Phaephe ea tšepe e se nang sekoli ea motsoako oa A335P92 ka lebaka la litšobotsi tsa eona tse ntle tsa ts'ebetso, e sebelisoa haholo masimong a latelang:
Setsi sa motlakase se futhumatsang: e le thepa ea bohlokoa bakeng sa phaephe e kholo ea mouoane le phaephe ea mouoane e futhumatsoang bocha, e ka mamella mocheso o phahameng le tikoloho ea khatello e phahameng ho netefatsa ts'ebetso e sireletsehileng ea setsi sa motlakase.
Khemikhale ea Petro: Ts'ebetsong ea ho hloekisa peterole le tlhahiso ea lik'hemik'hale, e sebelisoa ho hlahisa lisebelisoa tse kang li-reactor, li-heat exchanger le liphaephe tsa phetisetso ho fihlela litlhoko tsa mocheso o phahameng le khatello le ho hanyetsa mafome.
Indasteri ea matla a nyutlelie: Litsing tsa matla a nyutlelie, e sebelisetsoa ho etsa litsamaiso tsa ho pholisa li-reactor tsa nyutlelie le liphaephe tse amanang le tsona ho netefatsa polokeho le botsitso ba tlhahiso ea matla a nyutlelie.
5. Litekanyetso tsa ho kenya tshebetsong le ditaelo tsa ho odara tsa Di-Tube tsa Boiler tsa Tshepe
Phaephe ea tšepe e se nang mokelikeli ea motsoako oa A335P92 e latela maemo a phahameng a ASTM A335/A335M. Ha ho odara, tlhahisoleseling e latelang e hloka ho hlaka:
Bongata (mohlala, ka maoto, dimetara, kapa metso)
Lebitso la thepa (phaephe e tloaelehileng ea tšepe e se nang moalo)
Sehlopha (P92)
Mokhoa oa tlhahiso (ho qeta ka mocheso kapa ho taka ka serame)
Litlhaloso (mohlala, bophara ba kantle, botenya ba lebota, jj.)
Bolelele (boholo bo arotsoeng le boholo bo fetohang)
Qetello ea ho sebetsa
Litlhoko tsa khetho (mohlala, khatello ea metsi le ho kheloha ha boima bo lumelletsoeng)
Tlaleho ea teko e hlokahalang
Nomoro e tloaelehileng
Litlhoko tse ikhethang kapa litlhoko life kapa life tse ling tse tlatsetso tse ikhethileng
Ka bokhutšoanyane, phaephe ea tšepe e se nang mokelikeli ea A335P92 ke phaephe ea tšepe e se nang mokelikeli ea boleng bo holimo ea mocheso o phahameng le khatello e phahameng, e sebelisoang haholo masimong a mangata ka litšobotsi tsa eona tse ntle tsa ts'ebetso. Ha ho odara le ho sebelisoa, ho hlokahala ho latela ka tieo litekanyetso le litlhoko tse amehang ho netefatsa polokeho le ts'epo ea eona.
Rea u amohela ho ikopanya le rona bakeng sa lintlha tse ling!
