I-UNS S31803 Duplex Stainless Steel

I-UNS S31803 iyizinga elimele le-duplex yensimbi engagqwali equkethe u-22% we-chromium kanye ne-nickel engu-5%, evame ukubizwa ngokuthi i-Alloy 2205. Le nto inokumelana nokugqwala okuhle kakhulu okujwayelekile futhi amandla aphezulu yizinga le-duplex elisetshenziswa kakhulu.

Ibanga le-2205 linikeza ukumelana okuhle kakhulu nokugqwala kwe-intergranular, i-pitting kanye nokugqwala kwe-crevice kuhlanganiswe nokumelana kwayo ne-chloride stress corrosion cracking emazingeni okushisa angama-50- 300ºC. I-Alloy 2205 insimbi engagqwali iguquguquka ngokwedlulele ngokusetshenziswa okuningi embonini kawoyela negesi, i-petrochemical, kanye nezimboni zokucubungula amakhemikhali.

Izicelo

Izinsimbi ezingenasici ze-Duplex S31803 zivame ukusetshenziswa ku:

Ukucutshungulwa kwamakhemikhali| Imishini yokukhiqiza i-Chloroethylene, i-methanol synthesis reactor, ezokuthutha i-acetic acid, nokugcinwa

Amafutha negesi| Ukuhlola uwoyela negesi nokuhamba, imishini yokuqhekeka ye-Catalytic, imishini ye-hydrotreating

Izindawo zasolwandle, imishini yokulawula ukungcoliswa kwemvelo, ukukhiqizwa kwe-Pulp & iphepha, indawo yokucubungula ukudla, njalonjalo.

I-alloy S31803 isetshenziswa kakhulu ezimbonini zikawoyela negesi, izimboni zasolwandle, ukucubungula amakhemikhali, nezimboni zenuzi ngenxa yamandla ayo amahle kakhulu kanye nokumelana nokugqwala okuhle. I-Lkalloy ingomunye wabathengisi abahamba phambili be-S31803 ipayipi lensimbi engagqwali, ishubhu, ipuleti, nokufakwa kwamapayipi esixazululweni esilashwayo nesicinyiwe.
