I-Duplex 2205 VS 316 Insimbi Engagqwali

I-316 insimbi engagqwali iyinto evamile, esetshenziswa kabanzi ku-petrochemical, izitshalo zikamanyolo, ukwakhiwa kwemikhumbi nezinye izimboni. Ukufakwa kwensimbi eyi-duplex 2205 kuya ngokuya kuba banzi, ikakhulukazi emafutheni asogwini lolwandle, ekukhishweni kukasawoti emanzini olwandle nakwezinye izinkambu ezinezidingo zokugqwala okuphezulu. Ukuthi uzosetshenziswa yini316 ipayipi lensimbi engagqwalinoma i-duplex pipe iyinkinga amakhasimende ethu avame ukuhlangana nayo. Lesi sihloko sethula kafushane umehluko phakathi kwe-duplex 2205 kanye ne-316 yensimbi engagqwali. Ngethemba ukuthi kuzoba usizo kuwe.

Umehluko Wamakhemikhali PhakathiI-Duplex 2205kanye ne-316 SS

I-316 insimbi engagqwali isetshenziswa kakhulu embonini yamakhemikhali ngenxa yokumelana kwayo nokugqwala okuhle kakhulu. Ine-elementi ye-molybdenum engu-2-3%, futhi ingeyokuphuma kwe-18-8 austenitic stainless steel. Ngokuqondene ne-Duplex 2205, yengezwe ne-nitrogen ukuze kuthuthukiswe ukumelana kwayo nokugqwala. Futhi isixazululo esiqinile izicubu e ferrite futhi austenite uye matasa ingxenye ngayinye, okungenani oyedwa wabo uyofinyelela 30%, okwenza kube ukwenza izici ferrite futhi austenitic insimbi engagqwali.

Umehluko Phakathi kwe-Duplex 2205 kanye ne-316 Stainless Steel

• a) Amandla okukhiqiza we-duplex 2205 aphakeme ngesikhathi esisodwa kuno-316L, futhi inokuqina okwanele kwepulasitiki yokubunjwa. Futhi ubukhulu bodonga lomkhumbi wokucindezela owenziwe nge-duplex 2205 buncane ngo-30-50% kunobu-316L, obungasindisa izindleko.

• b) I-Duplex 2205 yenza kahle kakhulu ekumelaneni nokugqwala kwengcindezi, ikakhulukazi uma isetshenziswa endaweni yasolwandle equkethe ama-ion e-chloride. Kodwa-ke, ukugqwala kwengcindezi kuyinkinga evelele okufanele ixazululwe ngensimbi engagqwali ye-austenitic kufaka phakathi i-316L.

• c) I-Duplex 2205 yenza ukumelana nokugqwala okungcono kune-316L ekwenzayo ngezindlela eziningi. Isebenza ukumelana nokugqwala okuphezulu kakhulu ku-acetic acid, i-formic acid, futhi ingaba indawo yensimbi engagqwali ye-austenitic, kanye ne-alloy resistant corrosion. Kodwa-ke, ukukhetha i-duplex 2205 noma i-316L, kusanqunywa izidingo zemvelo kanye nezindleko.

• d) I-Duplex 2205 inamandla aphezulu futhi ifanelekile ukumelana nokugqwala kwendawo, ukumelana nokugqwala nokusebenza kokukhathala kokugqwala, okungcono kunensimbi engagqwali engu-316L.

• e) I-linear extension coefficient ye-duplex 2205 ingaphansi kuka-316L, futhi iseduze ne-carbon steel. Lokhu kwenza i-duplex 2205 ifanele ukuxhunywa kwe-carbon steel, okuletha ukubaluleka okukhulu kwezobunjiniyela.

• f) Kungakhathaliseki ukuthi ingaphansi kwezimo zomthwalo oguquguqukayo noma omile, i-duplex 2205 inamandla okumunca amandla aphezulu kuno-316L, okuletha izinzuzo ezisobala namanani okusebenza angokoqobo ezingxenyeni zesakhiwo noma amapayipi lapho kubhekwana nezimo eziphuthumayo ezinjengomthelela, ukuqhuma.

Ububi be-Duplex 2205

Ngezinzuzo eziningi kangaka, i-duplex 2205 ibonakala ingaphezu kuka-316. Nokho, uma iqhathaniswa ne-316, i-duplex 2205 nayo inokungalungi:

• a) Ukusetshenziswa kwe-duplex 2205 akuyona indawo yonke noma ahlukene njengo-316L. Isibonelo, uma umuntu edinga ukusebenza ngaphansi kwezinga lokushisa elingaphansi kwama-degree angu-250 isikhathi eside, khona-ke kuphela i-316L yensimbi engagqwali ingaba nekhono.

• b) Ukuqina kwepulasitiki ye-duplex 2205 impofu kuno-316L, futhi yenza kabi kakhulu ekucubunguleni nasekubunjweni okubandayo.

• c) I-Duplex 2205 ine-brittleness yezinga lokushisa eliphakathi, futhi ukwelashwa kokushisa kanye nesistimu yenqubo yokushisela idinga ukulawulwa ngokuqinile, ukuze kugwenywe isigaba esiyingozi ukuthi sivele, sibangele umonakalo.

• d) Uma kuqhathaniswa nensimbi engagqwali ye-austenitic, ubuthakathaka bensimbi engagqwali eyi-duplex ukuthi iqukethe inani elikhulu lezicubu ze-ferrite.

Izindleko ze-Duplex 2205 VS 316 SS

Abanye abantu bangase bacabange ukuthi intengo ye-duplex steel iphezulu kakhulu, iphakeme kakhulu kune-316 insimbi engagqwali. Eqinisweni, kuncike kumkhiqizo.

Sinikezela ngepayipi nokufakwa kokubili kwe-duplex 2205 kanye ne-316 SS, wamukelekile ukuthi usithinte uma kukhona izidingo.
