I. Kakaretso ea Sehlahisoa
GB/T9948-2013Phaephe ea tšepe e se nang moedi ke phaephe ea tšepe e se nang moedi ea boleng bo holimo e sebelisoang ka ho khetheha bakeng sa ts'ebetso ea ho petsoha ha peterole, 'me e sebelisoa haholo lisebelisoa tsa bohlokoa tse kang lipeipi tsa sebōpi, li-heat exchanger le lipeipi tsa khatello libakeng tsa ho hloekisa oli. Tekanyetso ena e laola ka tieo thepa, ts'ebetso ea tlhahiso le litlhoko tsa ts'ebetso ea lipeipi tsa tšepe ho netefatsa ts'ebetso ea tsona e tsitsitseng libakeng tse nang le mafome a mangata, mocheso o phahameng le khatello e phahameng.
2. Lisebelisoa le ts'ebetso
1. Lisebelisoa tse ka sehloohong
GB/T9948-2013Liphaephe tsa tšepe tse se nang moedi li entsoe ka mefuta e fapaneng ea thepa ea boleng bo holimo ea motsoako, ho kenyeletsoa:
Tšepe ea mohaho oa k'habone:20G, 20MnG, 25MnG
Tšepe ea meaho ea motsoako:15MoG, 20MoG, 12CrMoG, 15CrMoG, 12Cr2MoG, 12CrMoVG, 12Cr3MoVSiTiB
Tšepe e sa ruseng le tšepe e sa keneleng mocheso: 1Cr18Ni9, 1Cr18Ni11Nb
2. Tshebetso ya mantlha
Ho hanyetsa mocheso o phahameng: E loketse lits'ebetso tsa mocheso o phahameng joalo ka ho petsoha ha peterole (ho fihlela ho 600°C kapa ho feta).
Ho hanyetsa khatello e phahameng: Thepa e matla haholo e netefatsa ts'ebetso e sireletsehileng ea liphaephe tlas'a maemo a khatello e phahameng.
Ho hanyetsa mafome: Likarolo tse khethehileng tsa motsoako li hanela ka katleho lintho tse senyang tse kang hydrogen sulfide le carbon dioxide.
Tšepo e phahameng: Taolo e tiileng ea boleng e netefatsa hore thepa ea mechini le sebopeho sa lik'hemik'hale tsa liphaephe tsa tšepe li fihlela maemo a GB/T9948.
3. Ts'ebetso ea tlhahiso
Liphaephe tsa tšepe tse se nang moedi tsa GB/T9948-2013 li hlahisoa ka ho phutholla ho chesang le ho hula ka mokhoa o batang (ho phutholla):
Mokhoa oa ho phutholla o chesang: billet ea tube e chitja → ho futhumatsa → ho phunyeha → ho phutholla → boholo → ho pholisa → ho otlolla → tlhahlobo ea boleng → polokelo.
Mokhoa oa ho hula ka mokhoa o batang (ho pitikisa): ho phunyeletsa → ho pikitla → ho taka ka mokhoa o batang → kalafo ea mocheso → ho otlolla → ho lemoha liphoso → ho tšoaea → polokelo.
Mekhoa ena ka bobeli e netefatsa ho nepahala ho phahameng, bokaholimo bo boreleli le thepa e ntle ea mechini ea lipeipi tsa tšepe.
4. Masimo a kopo
Liphaephe tsa peterole tsa GB/T9948 li sebelisoa haholo ho:
Indasteri ea peterole: yuniti ea ho petsoha, seakere sa hydrogenation, lisebelisoa tsa ho ntlafatsa li-catalytic
Indasteri ea ho hloekisa oli: liphaephe tsa sebōpi sa mocheso o phahameng, liphaephe tsa mocheso, liphaephe tsa khatello e phahameng
Tsamaiso ea khase ea tlhaho: liphaephe tsa phetisetso ea khase tse hanelang mafome, tse nang le khatello e phahameng
Tlhahiso ea liboiler: liboiler tsa seteishene sa motlakase, litsamaiso tsa liphaephe tsa boiler tsa indasteri
5. Menyetla ea 'maraka
Ka ntshetsopele e potlakileng ya indasteri ya peterole ya lapeng le kgolo ya tlhokeho ya mmaraka wa matjhaba, bongata ba thekiso ya diphaephe tsa tshepe tse se nang moedi tsa GB/T9948 bo ntse bo eketseha. Khanyetso ya yona e ntle ya mocheso o phahameng le ho hanyetsa mafome di etsa hore e be thepa ya diphaephe e kgethwang masimong a ho petsoha le ho hlwekisa peterole.
6. Litlhokomelo tsa ho reka le ho sebelisa
Khetho e tiileng ea thepa: Khetha thepa e loketseng ea GB/T9948 (joalo ka 12CrMoG, 15CrMoG, jj.) ho latela maemo a mosebetsi (mocheso, khatello, ho bola).
Setifikeiti sa boleng: Netefatsa hore phaephe ea tšepe e fihlela maemo a GB/T9948-2013 mme o fane ka tlaleho ea tlhahlobo ea motho oa boraro.
Ho kenya le ho hlokomela: Qoba tshenyo ya mechini nakong ya ho tsamaiswa le ho kenngwa, mme o hlahlobe kgafetsa mafome a diphaephe le maemo a kgatello.
Phaephe ea peterole ea GB/T9948-2013 e fetohile khetho e ntle bakeng sa liindasteri tsa peterole, tsa ho hloekisa, tsa khase ea tlhaho le tse ling ka lebaka la melemo ea eona ea ho hanyetsa mocheso o phahameng, ho hanyetsa khatello e phahameng le ho hanyetsa mafome. Ho khetha thepa e loketseng (joalo ka 12CrMoG, 15CrMoG, jj.) le ho latela maemo ka tieo ho ka netefatsa ts'ebetso ea nako e telele e sireletsehileng le e tsitsitseng ea phaephe.
Mantsoe a bohlokoa:#Phaephe ea ho petsoha ha peterole, #GB/T9948, #GB/T9948-2013 phaephe ea tšepe e se nang mohele, #Peipi ea tšepe e petsohang ea peterole, #12CrMoG, #15CrMoG, #Phaephe ea tšepe ea mocheso o phahameng le khatello e phahameng, #Phaephe ea lik'hemik'hale tsa peterole
