S32750 Tšepe e sa Khabeng e se nang Seamless Tubing
Selelekela sa Sehlahisoa
Super Duplex e sa hloekang joaloka S32750, ke sebopeho se kopaneng sa austenite le ferrite (50/50) se ntlafalitseng matla ho feta maemo a tšepe a ferritic le austenitic. Phapang e kholo ke hore Super Duplex e na le molybdenum le chromium e phahameng e fanang ka thepa e kholo. Chromium e phahameng e boetse e khothalletsa ho thehoa ha mekhahlelo e kotsi ea intermetallic, e amehang ho brittleness ea 475°C ka lebaka la pula ea karolo ea α' e ruileng ka chromium, le ho brittleness ke sigma, chi le mekhahlelo e meng mochesong o phahameng.
Alloy 2507 (S32750) le yona e na le naetrojene e ngata, e seng feela e kgothaletsang ho thehwa ha austenite le ho eketsa matla, empa hape e diehisa ho thehwa ha mekhahlelo ya methale e fapaneng ho lekana ho dumella ho sebetswa le ho etswa ha sehlopha sa duplex.
Sehlopha sena se khetholloa ka ho hanyetsa mafome a chloride hantle haholo, hammoho le matla a phahameng haholo a mechini. Se loketse haholo ho sebelisoa libakeng tse mabifi tse kang metsi a leoatle a futhumetseng a nang le chlorine le mecha ea litaba e nang le asiti ea chloride.
Litšobotsi tsa Alloy 2507 (S32750) ke tse latelang:
● Ho hanyetsa ka mokhoa o babatsehang ho peperana ha khatello ea khatello ea maikutlo (SCC) libakeng tse nang le chloride
● Ho hanyetsa ka mokhoa o babatsehang ho ts'enyeho ea likoti le mapetso
● Ho hanyetsa ho hoholo ho bakoang ke ho bola ho akaretsang
● Matla a phahameng haholo a mechini
● Thepa ea 'mele e fanang ka melemo ea moralo
● Ho hanyetsa haholo ho bola ha khoholeho le mokhathala oa ho bola
● Ho tjheseletsa hantle
S32750 e etselitsoe lits'ebetso tse boima tse hlokang matla a ikhethang le ho hanyetsa mafome, tse fumanoang hots'ebetso ea lik'hemik'hale, disebediswa tsa peterole, le metsi a lewatle. E sebediswa haholo ho batlisiseng/tlhahisong ya oli le kgase le ho fapanyetsana mocheso tshebetsong ya peterole/dikhemikhale. Sehlopha sena se boetse se loketse ditshebediso tsa haeteroliki le tsa disebediswa dibakeng tsa lewatle tsa tropike.
