I-duplex steel

Yize kubalulekile ukukhumbula ukuthi ukugqwala okukhonkotha kungaba ukukhathazeka ngezixazululo ze-chloride lapho imithombo ye-oxidizing ikhona. Kulezi zimo, ungqimba lwe-Passive (lokuvikela) lwe-Duplex 305 Izinto ezibonakalayo zingahle zincishiswe ekuphaphemeni kwasendaweni kungenzeka.

Inhlanganisela ye-chromium, i-molybdenum ne-nitrogen inika i-Duplex 2205 FLANSEs Ukuvikelwa okuhle ku-chloride pittipt kanye nokugqwala kwamanzi, okubenza balusizo ezindaweni zasolwandle, okubenza basebenzise amasistimu wamanzi abunjiwe kanye nezinye izinhlelo zokufaka ukudla.

Lesi sigaba sezinto ezibonakalayo sifaka amabanga angama-2205, F51, F53, kanye noF60. I-Duplex Stainless ikhuphuke ngokudumile ngokuhamba kweminyaka ngenxa yezakhiwo zayo ezinhle kakhulu zamakhemikhali kanye nemishini eqhathanisa nabalingani bayo abayisisekelo abangenasici, banikezwe ikakhulukazi ukuthi ukwehluka kwezindleko kunciphile manje njengoba kutholakala ukutholakala.

I-2507 (uns S32750) iyinsimbi embi kakhulu ye-Super Dumplex eyenzelwe izinhlelo zokusebenza ezidinga amandla ahlukile nokuphikiswa kokugqwala. I-2507 i-chromium engama-25%, i-4% molybdenum, kanye no-7% nickel alloy aphumela ekumelaneni okuhle nokuhlaselwa kwe-chloride okukhohlisayo nokuhlaselwa kwe-crevice corrition.

Ngezengezo ze-chromium, i-molybdenum ne-nitrogen yokugqwala okwenziwe kwasendaweni njengokuphaphama nokuhlaselwa kwe-crevice kuyathuthukiswa. I-Alloy 2507 inokumelana okuhle kakhulu kwe-pitting yasendaweni.

Ukwakheka kwe-granular of Duplex kuyinto hrrite-aunten hybrid enamandla aphakeme wokulinganisa isisindo ngokuqhathaniswa no-304 noma 36. Ibhala ukufudumala kwe-auntenitic kanye nokugcina ukubonwa okuhle kwezicelo ezibonakalayo ezibandayo.

I-2205 isiza abasebenzisi ukuthi bagweme ukuqhekeka kokugqwayiza kwengcindezi okuvame ukubonwa nge-316 no-317.

I-DuPlex Steel Flange futhi inikezela ukunqotshwa okuhle nokusebenza, ukumuncwa kwamandla okuphezulu kanye nokunwetshwa okuphansi okushisayo.

Lawa mabanga alungele insizakalo elungisiwe okulula ukuxhumeka kwe-Flange, kepha kancane kancane lapho kwakheka ukwakheka kwensimbi okuyinkimbinkimbi. Ngenhlanhla, ukusebenziseka kwe-Dumplex kube yizinhlaka eziyinkimbinkimbi futhi eziyindilinga kuncane kunenkinga ngensimbi ehlelekile enikezwe ukukhetha okubanzi kwensimbi elula yensimbi ethambile kuzinhlelo ezingezona ezonakalisayo.

Ukusetshenziswa kweDuplex 2507 kufanele kukhawulelwe kwizicelo ezingezansi 600¡Ã f (316¡Ã c). Ukuvezwa kokushisa okuphakanyisiwe kunganciphisa ukumelana nokuqina kokugqwala kwe-Alloy 2507.

I-2507 inenhlanganisela yezakhiwo ezinikezwe yisakhiwo se-auntenitic ne-ferrititic, kanye nokusheshisa okuhle nokusebenza.

I-Duplex stainless S31083 S32205 FLANSEs ngokumelana okuhle nokukhohlakala kwe-crevice

I-Super Duplex ANS S32750 yibanga elijwayelekile kakhulu le-Super Dumplex Emakethe. I-S32750 yensimbi engenacala yeDuplex yenzelwe inkonzo ezindaweni ezinolaka-eziqukethe okuqukethe okunolaka.

I-2507 nayo isetshenziswa emishini yokuklama igesi ye-Flue, ama-pulp kanye nemishini yokugaya amaphepha, ukukhiqizwa kukawoyela osogwini lolwandle

Isakhiwo se-Duplex sinikezela nge-2507 ngokumelana okuhlukile ekuphepheni kokuphamba nokucindezela kwe-chloride.

Uma uqhathanisa ne-SS316, iDuplex 2205 ihlolwe ngaphansi kwengcindezi yokugoba emuva ekushiseni kwegumbi. Imiphumela ikhombisa ukuthi umkhawulo wokukhathala

I-Duplex 2507 ivame ukusetshenziswa emishini yokuhlanza, imikhumbi yengcindezelo yamakhemikhali, amapayipi kanye nokushintshana kokushisa kanye nezicelo zasolwandle.

I-Alloy 2507 inama-chromium angama-25%, ama-4% molybdenum, kanye ne-7% nickel. Le molybdenum ephezulu, i-chromium kanye ne-nitrogen okuqukethwe kuphumela ekumelaneni okuhle nokuhlaselwa kwe-chloride nokuhlaselwa kwe-chlorce kanye nesakhiwo se-duplex enikezela nge-2507 ngokumelana okuhlukile kokuqhekeka kokugqwala kwe-chloride ukuqhekeka.

I-auntenitic-Ferritic ehlukile ngokuhlukahluka okuphezulu kwengcindezelo yokuqhekeka kokuqhekeka ngokuqhathaniswa ne-Auntenitic 304 no-316 amabala, kepha ngobunzima obuphansi kanye namandla aphansi.

Ama-Flanges angama-2205 enziwe ngensimbi ye-auntenitic-Ferritic yensimbi engenacala, eyayenzelwe ukuletha amandla aphezulu nokuphikiswa kokugqwala ngaphezu kwama-300 uchungechunge lwensimbi engenacala.

Zombili i-ASME B16.5 ne-ASME B16.47 zivumele ama-flanges amaphayipi enziwe ngochungechunge lwamabanga angenacala.

I-Super Duplex 2507 nati emelana nokugqwala okufanayo ngama-organic acid

Bamelana nokugqwala okujwayelekile. Singabahlinzeki be-ASME SA182 Duplex Slow Uns S32205 Weld intamo evuthayo emanzini olwandle nemishini yokuphehla yamandla.

I-Duplex 2205 Flanges ihlanganisa izimfanelo zokuphikiswa kokugqwayiza kwengcindezelo kanye namandla aphezulu athathwe ekubeni yi-alloy ye-ferrititic kanye namakhono ayo e-autusinitic.

I-Duplex 2507 inokumelana okuphezulu kokuqhekeka kokugqwayiza kwe-chloride ukuqhekeka, amandla aphezulu, kanye nokumelana okuphakeme ku-chloride pitting kanye ne-crevice corrision.

Ama-Flanges angama-2205 anikela ngokumelana nokugqwala okuhle kwe-sulfide, kanye ne-chloride pittipt kanye ne-crevice corrosion engamelana ne-317l.

I-2507 inokumelana kahle nokugqwayiza okujwayelekile, okuphakanyisiwe ngezicelo kuze kufike ku-600¡Ã f, kanye nezinga eliphansi lokunwetshwa kwe-thermal.

I-2205 Flange inokumelana nokugqwala okujwayelekile okujwayelekile, ukumelana okuphezulu kokuqhekeka kokugqwala kwe-chloride ukuqhekeka, kanye nokugqwala okukhohlisayo kanye ne-crevice.
