ASTM A789 S32205 Duplex Stainless Hlau Tube
Tso lus
GNEE tuav cov khoom lag luam loj ntawm 2205 stainless hlau kav rau kev xa khoom sai, nrog cov lus qhia ua tiav nrog rau sab nraud ntawm 6.35-273 hli, phab ntsa thicknesses ntawm 0.3-30 hli, thiab cov qauv ntev ntawm 5.8 / 6 m lossis customized ntau thiab tsawg. Dimensional tolerances yog nruj me ntsis tswj ntawm OD ± 0.13 rau ± 0.76 hli thiab WT ± 10% rau ± 15%. Peb muab siab-lub zog, muaj zog corrosion heev- tiv taus, thiab txhim khu kev qha piping kev daws teeb meem rau siab -siab kub exchangers, reactors, thiab cov khoom siv nyob rau hauv corrosive ib puag ncig.
ASTM A789 UNS S32205 duplex stainless hlau kav peb muab tau raug tsim nrog ferrite + austenite dual- theem qauv (45-55% sib npaug microstructure). Ob leeg seamless thiab welded daim ntawv muaj. Rau siab - cov ntawv thov siab, UNS S32205 seamless kav raug pom zoo. Rau UNS S32205 welded kav, peb nruj me ntsis yuav tsum ua kom tiav cov tshuaj annealing ntawm 1050-1100℃tom qab vuam kom tshem tawm cov compositional segregation nyob rau hauv weld cheeb tsam.
Tshwj xeeb tshaj yog rau kev lag luam hluav taws xob sib txawv, peb xav tau lub puab nto ntawm UNS S32205 cov raj kom ua tau raws li cov qauv kev huv huv, suav nrog kev ua kom tiav, tsis muaj oxide nplai, thiab tsis muaj roj paug. Yog li, Pickled & Passivated lossis Bright Annealed processing feem ntau tau teev tseg. Cov khoom muaj qhov ntsuas kub ntawm qhov ntsuas kub (CPT) Ntau dua lossis sib npaug li 40 degree, zoo heev tiv thaiv chloride kev nyuaj siab corrosion cracking, thiab lub neej kev pab cuam 2-3 zaug ntev dua 316L austenitic stainless hlau.

S32205 vs. S31803: Qhov txawv tseem ceeb
UNS S32205 yog ib qho kev txhim kho ntawm thawj UNS S31803 (2205) duplex stainless hlau, muaj cov ntsiab lus nruj dua uas tsis tsuas yog txhim kho corrosion tab sis kuj nce qhov tsawg kawg nkaus txwv rau cov alloy cov tshuaj muaj pes tsawg leeg. S32205 (F60) qhia tau hais tias kev ua tau zoo dua thiab ruaj khov hauv cov tshuaj chloride- nplua nuj ib puag ncig thiab feem ntau tuav ob daim ntawv pov thawj, ua rau nws ua tau raws li qhov yuav tsum tau ua ntawm ob qho tib si qauv.
