Molemo tjheseletsa le thepa e meng, loketseng bakeng sa ho lokisa sebopeho se seholo sa sekepe le sekepe hull tšepe.Ho hlokahala tšepe ea sekepe hore e be le matla a phahameng, ho tiea ho betere, ho hanyetsa ho kokota le ho hanyetsa ho putlama ha metsi a tebileng.

6. Tšepe bakeng sa likepe tsa khatello

Tšepe e sebelisoang ha ho etsoa likepe tsa khatello bakeng sa petrochemical, karohano ea khase le polokelo ea khase le lisebelisoa tsa lipalangoang.Hoa hlokahala ho ba le matla a lekaneng le ho tiea, ts'ebetso e ntle ea welding le bokhoni bo batang le bo chesang ba ho sebetsa.Tšepe e sebelisoang hangata ke tšepe e tlase ea alloy e phahameng le tšepe ea carbon.

7, tšepe e tlaase ea mocheso

Bakeng sa ho etsa lisebelisoa tsa khatello le meaho e ka sebelisoang ka tlase ho -20 ℃, ho hlokahala litšepe tse nang le mocheso o tlase o thata le thepa ea tjheseletsa.Ho ea ka mocheso o fapaneng, tšepe e ka sehloohong ke tšepe e tlaase ea alloy, tšepe ea nickel le tšepe e sa hloekang ea austenitic.

8, tšepe ea boiler

Tšepe e sebelisitsoeng ha ho etsoa superheater, phala e kholo ea mouoane, phala ea lebota la metsi le moqomo oa boiler.Hoa hlokahala ho ba le thepa e ntle ea mochine mocheso oa kamore le mocheso o phahameng, oxidation le alkaline corrosion resistance, matla a lekaneng a nako e telele le polasetiki e tsitsitseng ea fracture.Tšepe e ka sehloohong ke tšepe e sa keneleng mocheso oa pearlite (tšepe ea chromium-molybdenum), tšepe ea austenitic e hanyetsanang le mocheso (tšepe ea chromium-nickel), tšepe ea boleng bo phahameng ba k'habone (tšepe ea 20) le tšepe e tlase ea alloy e matla haholo.

9. tšepe ea pipeline

Tšepe bakeng sa oli le khase ea tlhaho nako e telele karohano pipe line.Ke tšepe e matla e tlase ea alloy e nang le matla a phahameng, ho tiea ho holimo, machinability e ntle haholo, ho cheseha le ho hanyetsa kutu.

10, tšepe e matla e phahameng haholo e fana ka matla le matla a thata a fetang 1200MPa le 1400MPa ka ho latellana.Litšobotsi tsa eona tse ka sehloohong ke matla a phahameng haholo, boima bo lekaneng, bo ka mamella khatello ea kelello e ngata, ka nako e ts'oanang e na le matla a mangata a khethehileng, e le hore sebopeho se ka khoneha ho fokotsa boima ba 'mele.

11. Ha ho bapisoa le tšepe e tloaelehileng ea carbon structural, tšepe ea boleng bo phahameng ea carbon structural e na le lintho tse tlaase tsa sebabole, phosphorus le li-inclusions tse seng tsa tšepe.Ho latela litaba tsa khabone le ts'ebeliso e fapaneng, e arotsoe ka tšepe e tlase ea khabone, tšepe ea khabone e mahareng le tšepe e phahameng ea carbon, joalo-joalo, e sebelisoang haholo ho etsa likarolo tsa mochini le liliba.

12. Alloy sebopeho tšepe

Motheong oa tšepe ea sebopeho sa carbon e nang le likarolo tse loketseng tsa alloying, e sebelisoa haholo ho etsa tšepe ea likarolo tsa mochini tse nang le boholo bo boholo ba karolo.E na le ho thatafala ho loketseng, matla a phahameng, ho tiea le matla a mokhathala le mocheso o tlase oa phetoho ea brittle ka mor'a phekolo e tšoanang ea mocheso.Mofuta ona oa tšepe haholo-holo o kenyelletsa tšepe e thata le e futhumatsang, tšepe e thata ka holim'a metsi le tšepe e batang ea polasetiki.

13. Tšepe e thibelang mocheso

Alloy tšepe e nang le matla a phahameng le botsitso bo botle ba lik'hemik'hale ka mocheso o phahameng.Ho kenyelletsa oxidation - tšepe e hanyetsanang (kapa e bitsoa mocheso - tšepe e hanyetsanang) le mocheso - litšepe tse matla tse peli.Tšepe e hanyetsanang le oxidation hangata e hloka botsitso bo betere ba lik'hemik'hale, empa e jara meroalo e tlase.Tšepe ea matla a mocheso e hloka matla a mocheso o phahameng le khanyetso e kholo ea oxidation.

14, tšepe ea boemo ba leholimo (tšepe ea sepakapaka e hanyetsanang le kutu)

Kenya koporo, phosphorus, chromium, nickel le lintho tse ling ho ntlafatsa ho hanyetsa kutu ea sepakapaka ea tšepe.Mofuta ona oa tšepe o arotsoe ka litšepe tse phahameng tsa boemo ba leholimo le litšepe tsa welding.
